INTRODUCTION General The present manual is designed for Customer Service engineers who wish to familiarise themselves with the maintenance work required for the various truck components. It also contains troubleshooting sections which can be used to identify and remedy truck faults.
INFORMATION This book is not an operating manual. It is designed solely for specialist personnel who have been trained and authorised to carry out the work described in the manual.
This manual therefore contains fewer and less detailed warnings than the Operator’s Manual, as the latter is aimed at persons who have very little or no prior experience at all.
Operating Instructions This manual contains no operating instructions. An operating instructions manual is supplied with the vehicle. Additional copies can be ordered as required. With the help of this manual you and your personnel will be able to ensure the long service life, operational safety and error free functioning of your CROWN vehicle.
Service Training CROWN offers the appropriate vehicle related training for service personnel. Details on this training can be obtained from CROWN on request.
Ordering Spare Parts The maintenance manual does not cover spare parts. These are listed in a separate manual. Spare parts can be ordered by quoting: ●
The truck specification number
●
The truck model number
●
The truck serial number
This information can be found on the truck’s data plate. Only if this information is provided can the order be processed quickly, correctly and reliably.
Please refer to the Technical Specifications Sheet for the utilisable loads, technical data and dimensions for thisseries. Brochures can be obtained from your CROWN dealer or from the following address: CROWN Gabelstapler GmbH & Co.KG Moosacher Str. 52 80809 Munich GERMANY Tel.: +49 (0)89 / 93 002 -0 Fax: +49 (0)89 / 93 002 -175 oder 133

LUBRICATION AND ADJUSTMENT Lifting by another truck
Lifting the Truck
The SC 3200 can be lifted by another truck from the side.
CAUTION Scalding hazard! Spilled battery acid can cause injuries and damage the truck. You must remove the battery before transporting the truck. DANGER
Calculate the minimum capacity requirement based on the weight of the truck. This information can be found on the truck data plate. ●
Position the forks of the truck which is doing the lifting as shown by the diagram below.
●
Secure the SC 3200 firmly to the forks of the truck which is doing the lifting (e.g. with appropriate straps).
Falling loads are hazardous! Accidents can result from lifting gear with insufficient capacity and unsecured loads. Always use lifting gear with sufficient capacity and prevent the load slings from sliding. 0,51 m
Lifting by Crane Calculate the minimum capacity requirement based on the weight of the truck. This information can be found on the truck data plate. Attach the 3 straps to the hitch points as shown.

LUBRICATION AND ADJUSTMENT Towing the Truck If the truck is out of order it can only be towed if the handbrake is released.
WARNING Towing is only allowed with a tow bar.
●
●
First jack up the rear section of the truck:
●
Support one side with a wooden block.
●
Then jack up the truck at the opposite side until the steered wheels are free (see figure).
●
Support the raised side.
●
Then lift the opposite side and support it.
●
To jack up the front section of the truck, place the jack under the chassis frame behind one of the front wheels.
●
As soon as this drive wheel is free, support the outer part of the mast on this side.
●
Repeat this process to lift and support the opposite side.
The brakes of the towing vehicle must be capable of braking the towed vehicle.
Jacking up the Truck DANGER Always support a raised truck with wooden blocks or other appropriate equipment to relieve the jack. Never reach your hands or other parts of your body under the truck before it has been supported, or while jacking the truck up! ●
Improper handling of the truck or of the auxiliary equipment can result in fatal accidents.
To jack up the truck, the forks must be completely lowered (with no load on them) and the parking brake applied. Required capacity of the jack = 0.5 × overall truck weight. Do not forget to include the battery weight.

LUBRICATION AND ADJUSTMENT Counterweight WARNING Trapping hazard! The counterweight weighs at least 800 kg. Hands and feet can be trapped. Only use levers and suitable tools when assembling and disassembling. Never use hands or feet. WARNING Falling load hazard! A falling counterweight can result in serious trapping. Prevent the counterweight from falling. To do this, use a load sling suspended to a crane. The load sling must be pulled through the hole for the tow pin. The crane must have a minimum capacity of 1000 kg.
Disassembly Tools required: 1.
For disassembly you will need a crane or forklift (minimum capacity 200 kg at 2.5m elevation) to support the overhead guard.
●
Remove the mounting screw of the electrical base plate from the counterweight.
●
Remove the mounting screws of the overhead guard from the counterweight.
2.
A second crane or forklift (minimum capacity 1000 kg at 2m elevation) to prevent the counterweight from tipping.
●
Raise the back of the overhead guard 1 – 2 cm and pull a load sling through the hole for the tow pin in the counterweight.
3.
A pallet truck (minimum capacity 1000 kg) with forks that will lower to fit under the counterweight.
●
4.
Hard wooden blocks to fit under the outer mast stages.
Insert the load sling into a crane hook (crane minimum capacity 1000 kg). If you are using a forklift instead of a crane, prevent the load sling on the fork of the truck from sliding.
●
Drive the truck into a secure maintenance area.
●
Tighten the load sling slightly.
●
Tilt the mast back as far as it will go (in the direction of the driver).
●
●
Lower the mast and fork carriage fully.
Drive a pallet truck (minimum capacity 1000 kg) underneath the counterweight. The forks must be positioned under the flat surfaces of the counterweight.
●
Place two wooden blocks, one on the left and one on the right hand side underneath the outer mast stage. This will prevent the truck from tilting onto the fork tips.
●
Raise the forks of the pallet truck until they are touching the counterweight.
●
Remove the mounting screws of the counterweight.
●
Pull the counterweight approx. 10 cm away from the forklift, using the pallet truck.
●
Raise the counterweight off the pallet truck using the crane, and place it of a flat surface.
●
Remove the battery.
●
Attach a load sling to the rear of the overhead guard. This will secure the overhead guard when you loosen the attachment. Alternatively, you can support the overhead guard from the side using a forklift.
●
Remove the tow pin from the counterweight.

LUBRICATION AND ADJUSTMENT Recommended Lubricants and Oils Lubricants The next page shows typical lubricants used by Crown itself in its factories. However, you can use any lubricants provided they meet the same technical criteria.
Cold Store Truck Lubricants Special hydraulic oil, lubrication oil and grease must be used for cold store trucks operating in low temperature conditions (see table on following page). An anticorrosion fluid (Crown no. 805236-004) must be applied to all screws, washers, nuts, pins, retaining rings etc. Carefully protect all electrical connections and components against corrosion. For detailed information, refer to chapter 4. Service intervals must be adapted to the conditions of use. This means they must be reduced as far as possible to prevent excessive wear.
Bringing the truck back into service If you wish to bring the truck back into service, proceed as follows: ●
Remove any anti-corrosion agents which have been additionally applied (apart from the cold store agents)*.
●
Jack up the truck, remove the wooden blocks and lower the truck.
●
Charge the battery or fit a charged battery.
●
Connect the battery.
●
Carry out the daily inspection.
* Do not apply high pressure cleaning agents and/ or solvents to the truck. Do not use metallic brushes. Do not wet clean the electrical system and do not use flammable solvents.
Taking the truck out of service If you wish to take the truck out of service for more than 3 months, proceed as follows: ●
Disconnect the battery from the truck.
●
Decommission the battery in accordance with the manufacturer’s instructions.
●
Clean the truck*). Lubricate in accordance with the maintenance manual.
●
If the truck is to be stored in harsh conditions (e.g. saline atmosphere) treat the surface of the truck with a suitable preservative to prevent corrosion.
●
Do not park the truck in the open air or in a humid environment. The ideal place is a dry room where the temperature and air humidity are as constant as possible. If the truck has to be covered, use an air-permeable material. Do not use plastic sheets. Otherwise, condensation may form.
●
Jack up the truck. Lower the chassis onto suitable wooden blocks so that the wheels clear the ground (prevents the wheels from flattening from constant pressure).
●
Every 3 months connect the battery, carry out a daily inspection and activate all the truck functions. Now disconnect the battery again.

LUBRICATION AND ADJUSTMENT Inspection and Maintenance Schedule The following pages show the inspection and maintenance schedule for this truck. The service intervals are based on single shift operation under normal conditions. They should be reduced accordingly if the truck is to be operated in dusty or extreme conditions such as a cold store. Exact details should be discussed with a Crown service engineer. When carrying out maintenance routinely check for wear, corrosion, damage, component operation and safety. If in doubt, always replace a questionable part. The lubrication work for longer service intervals must also include the items covered under the shorter intervals.

HYDRAULICS Valve Block The valve block consists of an input unit, three (standard) or four operating units and an end unit. The input unit comprises the main relief valve for limiting the system pressure (set to 235 bar), the priority valve for preferential supply to the steering system when several hydraulic functions are activated and the relief valve for the steering (set to 70 bar). The pressure relief valve settings must not be changed. In the event of a fault, always replace the pressure relief valves. New valves are pre-set to the correct pressure.
●
If necessary, remove the foaming oil at zero pressure circulation by carefully opening the pressure flange (taking care to protect yourself against spray). When bubble-free oil flows out refit the flange.
Oil Change The hydraulic tank (capacity 37 litres) does not contain a drain plug. When changing the oil, the used oil must therefore be suctioned off via a suction pump.
Pump motor Refer to Chapter 4 for pump motor maintenance and repair instructions.
Hydraulic pump INFORMATION The hydraulic pump should not be repaired on site. For this reason it is supplied as a complete assembly only. When commissioning a new or repaired hydraulic pump proceed as follows:
Commissioning ●
Check that the assembly is clean and correctly assembled.
●
When adding hydraulic oil, you must use a filter with the prescribed minimum retention rate (10 µ).
●
Note the arrow direction.
●
Start the pump unladen and leave it to operate for a few seconds without pressure to allow for sufficient lubrication.
●
Never run a pump without oil.
●
If after 20 seconds the oil is still not free of bubbles, check the unit again.
●
When operating temperature has been reached check the pipes are not leaking.
Bleeding ●
To ensure maximum operating safety and minimum wear it is advisable to fill the pump housing with oil before starting.

HYDRAULICS Bleeding the hydraulic system WARNING Risk of serious injury from pressurized hydraulic oil. Pressurized hydraulic oil can penetrate the skin. This is a serious medical emergency which requires immediate medical attention.
●
Slowly open the vent screw on one of the tilt cylinders.
●
Tighten the vent screw as soon as bubble-free oil emerges.
●
Repeat the previous stages on the second tilt cylinder.
Bleeding the free lift cylinder ●
Prepare the work area to collect spilled oil.
●
Cover the brake disks with a plastic sheet to prevent the brake linings becoming contaminated with oil.
●
Raise the fork carriage to approx. 1,200 mm.
Always take the following precautions:
●
Depressurise the hydraulic system before starting assembly work on the hydraulic system.
Wear protective clothing, safety glasses and gloves before carrying out the next step.
●
Slowly open the vent screw on the free lift cylinder.
●
Tighten the vent screw as soon as bubble-free oil emerges.
●
Clean any oily components on the truck.
The skin will not show any obvious initial damage and the physical effects will not be manifested immediately. Seek medical assistance if your skin has been affected by pressurized hydraulic oil.
After carrying out assembly work carefully check to see that all ports are tightened before re-pressurising the system. Wear protective clothing, safety glasses and safety gloves when tracing leaks or bleeding the system. Use a piece of absorbent paper to trace leaks, never use your hands. Follow the hydraulic oil manufacturer’s safety instructions when handling these oils. Bleed the system after carrying out repairs to the free lift, lift and tilt cylinders.
CAUTION Possible damage! On hydraulic connections with O ring seals the O rings will be damaged if opened under pressure. Do not open connections with O ring seals for ventilation. Use only the vent screws provided on the assemblies.

HYDRAULICS Flushing the cylinders After bleeding the cylinders: ●
Extend the mast fully.
●
Check the cylinders for leaks.
●
Fully extend and retract the mast at least 10 times at max. speed to flush the system.
If this distance is exceeded, this could indicate internal leakage in one of the lift cylinders. It may also be caused by a foreign body in one of the valve seats. Flush the system again (extend and retract the mast at least 10 times). Now carry out the test again.
Tilt cylinder drift test ●
Fully extend and retract the mast several times from one end to the other to flush the hydraulic system.
●
Collect the maximum permissible load for a lift height of 2500 mm (see capacity plate on truck).
●
Tilt the mast backwards (towards the driver) up to the limit.
●
Raise the test load so that one of the fork tips is 2500 mm above the ground.
●
Switch off the truck and disconnect the battery.
Measure the temperature in the hydraulic reservoir before carrying out the tests.
●
Remove one of the floorboards to provide access to one of the tilt cylinders.
The test load must correspond to the maximum capacity at the respective lift height (see capacity plate on truck).
●
Measure the distance from the front of the cylinder gland to the clevis. Note down the reading.
●
Wait for 5 minutes.
●
Measure again the distance from the front of the cylinder gland to the clevis.
●
The difference should be max. + 16 mm.
Drift Tests After carrying out repairs to the hydraulic system perform a drift test. This is the only way of identifying internal leakage.
INFORMATION Whenever you carry out a drift test the hydraulic oil temperature must be 30 40 °C.
DANGER Falling loads are hazardous! You could be fatally injured by a falling load. Never stand underneath a raised load. The test load must be evenly distributed. The load centre of gravity must be centrally located and must not exceed the capacity plate specification. Secure the test load to prevent it from slipping and falling.
Lift cylinder drift test ●
Fully extend and retract the mast several times to flush the hydraulic system.
●
Collect the maximum permissible load for the highest lift height (see capacity plate on truck).
●
Attach a measuring tape to one of the fork tips.
●
Extend the mast fully.
●
Switch off the truck and disconnect the battery.
●
Measure the distance from the fork tip to the ground.
●
Wait for 10 minutes.
●
Measure again the distance from the fork tip to the ground.
●
The load should lower max. 100 mm.
SC3200 03/2004 • Printed in Germany
If this distance is exceeded, this could indicate internal leakage in one of the tilt cylinders. It may also be caused by a foreign body in one of the valve seats. Flush the system again (tilt the mast from one end to the other at least 10 times). Now carry out the test again.
Steer unit drift test ●
Turn the steering wheel as far as it will go.
●

ELECTRICS Electrical Components DANGER The truck must be jacked up prior to carrying out repair work or troubleshooting the electrical system.
Switch Functions The pin references relate to the drive and pump control inputs.
Brake Switch (BRS) The brake switch switches the power supply to pin G6 of the traction controller. This amplifies inversion braking via the traction controller.
Encoder (ENC), Encoder Module (EM) Impulses are generated via the steering wheel, the steering column and the connected encoder ENC. These impulses are digitalised in the encoder module EM and transfered to the pump controller via pin E8.
Accelerator Pedal Switch (ACS, POT1) The accelerator pedal key movement is converted into a control signal via potentiometer POT1 and transfered to pin G1. The accelerator pedal switch ACS cuts off the electric circuit from the direction indicator switch DIS.
Direction Indicator Switch (DIS) The direction indicator switch has three switch positions: forward, neutral and reverse. When the forward or reverse positions are selected, power is supplied to the traction controller on pin G8 (F) or G7 (R). This causes the controller to activate the respective direction contactors.
Handbrake Switch (HBS) The handbrake switch sends battery supply to pin F1 of the traction controller. This causes the control system to disconnect the traction current. It is also possible to travel for 5 seconds with the handbrake applied (starting on an incline) before the controller interrupts the traction current.
SC3200 03/2004 • Printed in Germany
Raise Potentiometer (POT2) The key movement of the "Raise" operating lever is converted into a control signal by potentiometer POT2 and at C1 is fed into the pump controller. The controller in turn governs the pump motor speed.
Steering Axle Potentiometer (POT3) The steering axle potentiometer POT3 is mounted on the steering axle input shaft and gives the following control signals to the traction controller: ●
Travel direction;
●
Steering wheel angle of turn.
This signal enables the traction controller to steer the traction motors accordingly.
Tilt (TLT), Sideshift (SSS), Auxiliary Switch (AXS) The switches for tilting, sideshift and auxiliary function switch the battery supply to connections E2, E3 and E5 of the pump controller. The impulse controller governs the pump motor speed via preset voltages.
Emergency Disconnect The power supply to the truck is disconnected by pulling the battery connector.
Key Switch (KYS) The key switch energises the traction and pump controller via pins E1 and D1 as well as the battery discharge indicator BDI.
Fuses (FU) The main drive motor circuit is protected by fuse FU1 and the lift motor circuit by fuse FU2. The controller circuit is protected by fuse FU3 and the horn by fuse FU4. FU5 protects the supply voltage to the BDI.

ELECTRICS Zapimos B1S 48/700 Controller
Key Terms
General
Shunt or Shunt Resistor (+SH/-SH) The controller logic can measure the current flowing through the motor using a pre-defined resistance (shunt) in series with the motor and thus control the MOSFETs.
Volt Motor Negative (VMN) The measurement point for the controller logic. The voltage range on the terminal is measured and tests carried out to determine whether the controller power part
Functional Description M0201
Acceleration / Delay Rate The acceleration rate is the time taken for the voltage applied to the motor to rise incrementally to 100 % of the battery supply. The acceleration rate can be changed by the programmer.
Travel Switch ZAPIMOS B1S 48/700 Traction Controller
Protective Devices Polarity Protection Wiring must be laid out in accordance with the wiring diagram to avoid damaging the transistors and capacitors. The logic system itself is internally protected against incorrect polarity.
Wiring Errors The driver outputs for the contactors tolerate only a max. charge of 3A, even though they are protected against overload and short-circuiting.
Overheating When the temperature exceeds 80°C, the maximum current is reduced in proportion to the rise in temperature. If the temperature exceeds 85°C the traction controller cuts out.
Protection The traction controller is protected against dust and spray water (IP54) and is contained within a sealed housing.
SC3200 03/2004 • Printed in Germany
The travel switch stroke is 0 - 100% proportional to the controller output. Checking the travel switch signal on the control input prevents the truck from starting without the driver.
Travel Switch Signal Response The controller responds to the incoming travel potentiometer signal in accordance with the programmed acceleration rate. Changes in the travel potentiometer signal are converted linearly.
Fault Log The last 5 faults are stored in the controller memory along with the relevant number of service hours, the control temperature and the fault frequency.
Fault Identification The internal microprocessor monitors the controller. When a fault is identified, the controller status LED flashes a fault code. For critical faults the controller cuts out. For intermittent faults, e.g. low voltage, the error message automatically fades out after a while. Automatic Fault Identification covers: ●
Both travel directions operated simultaneously.
●
Logic error.
MS-4.3-2232
67
ELECTRICS ●
Incorrect start sequency; travel switch operated.
●
Volt Motor Negative Test (VMN) error.
●
High acceleration potentiometer resistance level when idle.
●
Current measurement error: – Travel: Maximum level exceeded; – Idle: Current ≠ zero.
●
Contactor drivers faulty.
●
Controller temperature above 80°C.
●
Contactors do not close or Volt Motor Negative is too high when idle.
●
Contactors welded.
Sparkless Contactors If a direction switch is switched off, the output voltage rapidly falls to zero. This causes the current to fall to zero before the direction contactor drops.
Inversion Braking With inversion braking the motor is electrically driven in the opposite direction to which it is mechanically turning. The controller governs the field current in order to achieve a controlled braking moment. During inversion braking the current is automatically restricted and the armature current is greater than the field current. The inverse current limit for fast travel can be adjusted using the programmer.
Creep Mode Creep speed is applied when the travel potentiometer is activated. Creep speed can be adjusted between 0 and 25 % of the output voltage. The setting can be adjusted via the potentiometer or the programmer.
Slow Travel In slow travel the maximum speed is reduced. However, the travel switch is still fully extended. The maximum speed setting can only be adjusted by the programmer.
Steering Controller When travelling around corners with the steering wheel at an angle of less than 65° the motors are controlled so that the inside motor is slower and the outside motor correspondingly faster.
MS-4.3-2232
68
When the steering angle is between approx. 65° and 73° the inside motor runs at idle speed. If the steering angle is greater than 73° the inside motor will turn in the opposite direction. This function is dependant on the steering angle measured by the potentiometer on the steering axle, the axle base and the track. The ratio of the two motor speeds corresponds to the ratio of the radii of the two load wheels.
45° Steering Angle Beyond a steering angle of 45° the controller automatically switches to creep speed.
Pedal Braking (Inversion Braking with Battery Supply Regeneration) In pedal braking the energy from the motor coil is not transfered into heat as in inversion braking but a part is fed back to the battery by the controller via the brake contactor. Pedal braking is activated when the operator's foot is taken off the accelerator pedal, the travel direction changed or the operating brakes are applied. If the voltage generated falls to a preset value – (VgenVbat) < 0.7 V – pedal braking is cut out (brake contactor re-opens) and the truck is stopped by the operating brakes (brake pedal).
Ramp Start Here the truck is started with a higher inverse braking current which prevents the truck from rolling backwards when it starts. Ramp start increases the current limit in the direction which has just been applied. Switching to the opposite travel direction ends the ramp start function.
Key Switch The key switch switches the voltage to the logic section of the impulse controller.
Self Test The controller is monitored by means of internal self tests. If an error occurs the controller is cut out. Switching the key switch off and on will cause it to re-start.
Reverse Travel Alarm The traction controller sends a signal via Pin H2 to the lighting module and from there to the horn to activate the alarm when reversing.
SC3200 03/2004 • Printed in Germany
ELECTRICS Seat Switch The seat switch circuit contains a time delay relay which interrupts the truck circuit when the operator has left the truck for a period of time. This prevents the truck from switching off caused by the operator moving or jolts received from the truck.
Current Limit The current limit function reduces the PWM signal to the controller power part until the motor current falls below the value of the current limit.
Overvoltage In the event of overvoltage the PWM cuts out and opens the contactors. When the permissable voltage has been reached the controller resumes operation.
Overheating At a temperature of 80°C the current limit is linearly reduced. At 85°C the controller cuts out.
Low Voltage Reduction The controller reduces the speed when the batteries are discharged to less than the minimum charge level. If the motor current is so high that the battery voltage falls below the low voltage level, the controller reduces the speed until the voltage exceeds above the level.

ELECTRICS Functional Description Acceleration / Delay Rate The acceleration rate is the time taken for the voltage applied to the motor to rise incrementally to 100 % of the battery supply. The acceleration rate can be changed by the programmer.
Hydraulic Switches The sideshift, tilt and aux. hydraulic functions are driven by switches. If applying an operating lever causes the switch to close, the pump motor operates at a preset speed controlled by the programmer. Steering has priority over lifting. Priority control is governed by a priority valve in the valve block.
Lift Cutout If the battery capacity falls below 20%, the battery discharge indicator sends a signal to the controller. The controller cuts out lifting.
Lift potentiometer The travel switch stroke is 0 - 100% proportional to the controller output.
Lift Potentiometer Response The controller responds to the incoming travel potentiometer signal in accordance with the programmed acceleration rate. Changes in the travel potentiometer signal are converted linearly.
Fault Log The last 5 faults are stored in the controller memory along with the relevant number of service hours, the control temperature and the fault frequency.
Fault Identification
Steering Support Signals are generated via an encoder. These are digitalized in the encoder module and sent to the pump controller. The pump controller then drives the pump motor at a speed which is preset by the programmer. Steering has priority over lifting. This is controlled by a priority valve in the valve block.
Key Switch The key switch switches the voltage to the logic section of the impulse controller.
Self Test The controller is monitored by means of internal self tests. If an error occurs the controller is cut out. Switching the key switch off and on will cause it to re-start.
Current Limit The current limit function reduces the PWM signal to the controller power part until the motor current falls below the value of the current limit.
Overvoltage In the event of overvoltage the controller range limit cuts out and opens the contactors. When the permissible voltage has been reached the controller resumes operation.
Overtemperature At a temperature of 80°C the output current is linearly reduced. At 85°C the controller cuts out.

ELECTRICS Battery General
Battery Discharge Indicator (BDI) WARNING The following setting and calibration instructions for the BDI apply only to wet batteries.
The battery condition has a considerable impact on the performance of the truck. Effective maintenance will maintain the performance levels and lifespan of the battery. ●
WARNING The battery must be serviced solely in accordance with the battery manufacturer's instructions. ●
Incorrect or inadequate maintenance will initially reduce the performance of the truck and ultimately result in premature failure of the battery.
It is essential to adjust the battery discharge indicator (BDI) correctly to ensure on the one hand that the battery is not fully discharged and on the other that there is maximum battery capacity available for the task in hand.
Replacing the battery WARNING Only use batteries of the permitted size, weight and specifications for this truck. ●
An incorrect battery type can cause damage to the truck.
●
An incorrect weight and size will alter the centre of gravity of the truck, potentially resulting in accidents.
There are several different battery compartment versions. Refer to the truck operator manual to battery replacement instructions. The operator manual contains the latest safety instructions and information.
For maintenance-free batteries follow the manufacturer's instructions regarding the discharge terminal voltage.
General A battery from the factory will require approx. 5 - 10 charge and discharge cycles to reach its full capacity. A battery is considered to be technically discharged when it has reached 20% residual capacity. For example, a battery with a 500 amp hour capacity has an actual available output of 400 amp hours. In addition, the effective output will depend on the discharge speed, which in turn is affected by the particular truck application. The battery discharge indicator must therefore be set in accordance with the truck's particular application conditions. The battery discharge indicator controls the lift cutout system. The lift cutout system is designed to prevent the battery from being operated to the point where is fully discharged. If the battery is constantly discharged to below 20% of residual capacity it will be damaged. If the lift cutout system is activated above 20% of the battery's residual capacity the battery will not be damaged, but the truck's maximum operating time under a single battery charge will not be attained. The lift cutout system should therefore be activated as close to 20% of the battery's residual capacity as possible. If at all, it may be slightly above 20%, but never below.
NOTE For new trucks the battery discharge indicator should be set at the latest after ten discharge and charge cycles.

ELECTRICS battery manufacturer's maintenance instructions to check if the battery is actually 100% charged. Faulty battery cells will make calibration impossible.
Battery Discharge Indicator Setting (BDI) The acid density is a very reliable indicator of the charge status of a lead acid battery. However, since it is unrealistic to continually measure the acid density of a truck battery to an industrial standard, the battery voltage is used to determine the charge status over longer journeys. To adapt the BDI to the battery used and the truck's specific application profile, you need the battery manufacturer's data sheet. The values you require are the density of the electrolyte for an 80% discharged battery (20% battery residual capacity) and for a fully charged battery (100% battery capacity). Finally, via the potentiometer on the back of the BDI the display is set to the actual discharge terminal voltage of the battery at 20% residual capacity.
●
Operate the truck as usual under normal operating conditions until the battery is empty: both LEDs of the BDI will flash and the lift cutout system will be triggered.
●
Leave the battery for at least 10 to12 hours (one hour at the very minimum!).
●
After this interval measure the acid density on at least three different battery cells. The smallest recorded value is the one you need.
●
Compare the recorded density with the density specified by the manufacturer for an 80% discharged battery (20% residual capacity).
●
If the battery is more than 80% discharged (less than 20% residual capacity), set the potentiometer on the back of the BDI to direction K.
●
If the battery is less than 80% discharged (more than 20% residual capacity), set the potentiometer on the back of the BDI to direction U.
●
Charge the battery again and then check the calibration.
The factory default setting of the battery discharge indicator is "M" (any setting from K to U is possible).
Calibration ●
Fully charge the battery as indicated by the battery manufacturer in the operating instructions. Measure the acid density in accordance with the

ELECTRICS Electric Motors
●
The brush edges must not be cracked. Brushes with cracking along the long edge of the surface will have been damaged by a worn collector. If information is provided in the manual, restore the collector to the specified limits. Otherwise, replace the armature in full.
●
Loose brush connections are a clear sign of motor overload. In this case inspect the collector for burning and repair or replace as necessary.
●
When fitting the brush take care to place the spring gently on the brush. If the contact is too hard the brush will be damaged.
●
Make sure that all brushes contact the armature at the same pressure.
●
New brushes must be run in with a medium load in the first hours. Never fully charge the motor straight away.
General Maintenance Instructions The following instructions apply to all motors. Details relating to specific models and designs are provided in the sub-sections (traction motor, pump motor etc.).
Preparation ●
Disconnect the battery (= EMERGENCY DISCONNECT).
●
Secure the truck from rolling away.
Important Maintenance Instructions ●
Remove all carbon brushes and check for wear. If one or more carbon brushes need to be replaced, replace all brushes. In addition to the carbon brushes the pressure springs must also be replaced to ensure the correct pressure. The length of the shortest brush determines whether the brush set needs to be replaced. Even if the minimum length has not been reached the brushes should be replaced as the remaining useful life could be much shorter than the time until the next inspection: If a brush is too short the spring will lie on the brush support. The brush sparks during operation and burns the collector with corresponding damage.
●
Blast the motor with dry compressed air only.
●
Check the armature for uneveness, burning, grooves and cracking of the multi-plate edges. Turn the armature if necessary. A non-oily, evenly distributed layer on the brush surfaces is normal.
●
If oil or grease is found in the motor collector compartment (usually a paste consisting of oil, oil vapour, dust and carbon particles), immediately remove the cause and clean the motor thoroughly: Oil or grease burns in the brush sparks and leaves behind a highly abrasive oil ash which can very quickly destroy the collector and the brushes.
●
The brushes must be able to move freely in the brush support (without spring tension) without tilting. Never modify brushes if one or more brushes cannot move freely. In this case replace all brushes as they will probably have been thermally overloaded. Thermal overloading (temperatures >160 ºC) causes the brushes to swell up. Brushes which jam in the brush support produce intense sparking and destroy the collector.

BRAKE On the brake linings which contact the rotor (brake applied), measure the distance between the two fixed plates (see Fig. MS-2232-010). The brake linings are worn if the distance is 11.8 mm or less.
Brakes General DANGER A falling mast section can have fatal consequences. When carrying out work which requires the mast sections to be raised: secure the raised mast stages to prevent them from suddenly falling (hard wooden blocks underneath the raised sections and if necessary chains around the cross arms of the mast stages)!
Brake Removal ●
Secure the truck with blocks under the wheels to prevent it from rolling away. Raise the inner mast until you can access the brakes through the mast. Lower the inner mast onto suitable square hard wooden blocks and secure it. De-pressurise the hydraulic system (see Chapter 2). Disconnect the battery.
●
If necessary, with the hydraulic system depressurised, remove the hydraulic lines and hoses in order to access the brakes.
●
Remove the floor boards. Remove the lower instrument panel cover. Undo the jam nut from the handbrake cable and discharge the brake cable (A, Fig. MS-2237-004).

MS-2232-002
NOTE To remove the brakes, replace the brake disks and the linings, you may need to disconnect the hydraulic connections, depending on the type of mast. Cover the brakes with a plastic sheet beforehand. This will prevent the brake linings from being contaminated with oil.
MS-2232-004 ●
If you have difficulty reaching the brakes, remove the drive motors (see Chapter 4). Although this is not strictly necessary, it can save considerable time.
●
Unscrew the cross strut which connects the two brake units (Fig. MS-2232-006 on following page).

Brake Assembly Before Assembling ●
Clean all parts with a brake cleaning agent or any other oil and silicon-free agent.
●
Check all parts of the brakes for damage and wear. Replace any faulty or worn parts. The fixed plates (with the brake lining) must always be replaced in pairs.
●
Now carry out the following adjustments and inspections: ●
Adjust the foot brake
●
Adjust the handbrake
●
Check the braking distance
See the following pages for instructions.
Replace any brake linings which have become oily over a long period of time. These will soak up too much oil. Cleaning is generally superficial and the oil will seep back to the surface during operation. Only when the oil has a short effect - e.g. when you have removed the brakes - can the it be removed with a brake cleaning agent and the brake lining re-used .
Assembly ●
Place the first fixed plate (4) on the stud bolts (5) of the base plate.

STEERING When the steering wheel is applied, oil flows from the oil tank to the spool valve via the hydraulic pump. The priority valve (2) distributes the flow of oil: the amount currently required for steering is routed to the steer unit (3). The rest is routed to the downstream hydraulic functions.
Steering Hydraulics Function The input unit of the spool valve (1) contains a priority valve (2). If the steering and at least one other hydraulic function are activated at the same time, the priority valve controls the distribution of the oil between the required functions. Steering always takes priority over the other function.
2 1
The proportions are determined by the LS signal (4) sent from the steer unit to the priority valve. As the load pressure increases, so the amount of oil flowing to the steer unit rises. A pressure relief valve restricts the operating pressure in the steer unit to 70 bar. Refer to the HYD chapter for a illustration of the steering hydraulic system.

MAST Lifting Gear Minimum Capacity
Mast (TT Series) DANGER Risk of trapping and severing limbs! When carrying out work on the mast and the attachments: always block the mast stages and attachments to prevent them from accidentally moving. Make sure the wooden blocks and lifting gear used have sufficient capacity.
General Torques Mast bearing mounting screws Torque the 4 mounting screws on the mast bearing blocks to 550 – 600 Nm.
Note the minimum capacity for the lifting gear whenever carrying out work on the mast. The required minimum capacity is as follows: Complete mast: 1,200 kg Attachments:
100 kg
Mast Testing (Assembled) Clean the mast channels and test the tracking paths of the rollers in the mast channels. There should only be wear in the rear section of the I beam where the rollers slide. There should not be any grooving or cutting in the I beam caused by the mast rollers. If grooving or cutting is evident, it will normally take place at the side of the roller; 10 mm from the channel face. In this case the mast rollers will have to be adjusted. Remove a shim from underneath the affected mast roller. A recheck of the mast channel will be required. De-grease the running area of the roller in the mast channel and spray on a thin layer of paint. Extend and retract the mast, and then check the tracking path of the roller (the paint will show up the tracking path). If the contact pattern matches requirements, apply grease to the contact surfaces (see lubrication table, chapter 1).
0
When the mast is raised and nearly fully extended, it should not tilt to the right or left but should be even and straight. All mast stages should be aligned. If a tilting condition exists, it is a sign that the shimming is too loose or unbalanced and will need to be adjusted. 550 - 600 Nm
All hose guide pulleys should move freely, check hoses for chafing.
Flaking It is not uncommon for a new mast to appear as if it is flaking or peeling. This appearance indicates that the rollers are seating on the mast channel and this is considered normal. Eventually, this condition will disappear. The grease applied to the channel will retain these particles.
MS-2232-011
Mast Stoppers Torque the mast stoppers to 122 – 149 Nm. Apply the standard torque to all the other screws (see table in Chapter 1).

MAST Mast Disassembly DANGER All assembly work on the mast is hazardous. Unsecured stage masts and attachments can sever limbs or even cause fatal injuries. Always block and secure the respective components properly prior to starting assembly. Pressurised hydraulic systems can cause serious injury when the opened.
Dismantling the Mast (Attached) General For the complete mast you required lifting gear with a minimum capacity of 1,200 kg. For attachments (fork carriage etc.) the minimum capacity of the lifting gear is 100 kg. ●
Remove the load backrest and fully lower the mast.
●
Disconnect the battery.
●
Reduce the system hydraulic pressure: To do this move the sideshift lever and if applicable the auxiliary function lever a few times backward and forward.
●
Place a flat tray underneath the mast area and collect any spilled hydraulic oil.
●
Cover the brakes with a plastic sheet. This will prevent the brake lining from being contaminated with oil.
●
Immediately seal any open hydraulic ports with filler plugs.
●
Item numbers in brackets refer to Figure MP2232-028.
Pressurised hydraulic oil can result in serious injury. Any fluid which penetrates the skin at high pressure must be considered as a serious medical emergency even if the skin does not initially show any unusual signs. The pain may take time to set in. Tighten all connections before pressuring the system again. Keep your hands and body away from holes as hydraulic oil could emerge at high pressure. Always use a piece of absorbent paper to trace leaks, never use your hands. The mast can be dismantled while attached to the truck, provided there is sufficient height and the crane used has the necessary lift height. Alternatively, dismantle the mast from the chassis, turn it over and dismantle it in a horizontal position.
DANGER Note the minimum capacity for the lifting gear required. Falling assemblies can sever limbs and cause fatal injuries.

MAST Replacing the Mast Rollers on the Mast To replace the mast rollers you need to remove the mast Stages and the Fork Carriage
Removing the individual mast stages stages.
First remove the fork carriage and the individual mast stages as described in the previous section. If it is impossible to remove the mast stages with the mast attached (height), completely detach the mast from the truck (see Removing the Mast from the Truck) and dismantle the mast in a horizontal position.
●
Attach a load sling to the cross member of the third mast stage.
●
Raise the third mast stages until the lift chains become slack.
●
Remove the lift cylinder attachments (15, 16, 17)
●
Disconnect all the hydraulic connections to the third mast stage so that it can be freely lifted out.
The mast rollers are available in three diameters: standard (part no. 074668-001), with 0.635 mm oversize (part no. 124321-025) and with 1.27 mm oversize (part no. 124321-050).
●
At the top of the second mast stage remove the lift chain, the pulleys and the hydraulic hoses.
A maximum of 6 shims may be placed under a roller.
●
Remove the cover (38) and the screws (42) from the top of the left-hand side of the second mast stage. Replace the cover (38) back on the pulley assembly.
Mast Stage Rollers 1.
First determine the roller diameter required for each mast stage. Use the roller with the diameter which just runs over the entire running area in the mast channel without jamming.
2.
Push the appropriate rollers onto the mast stage bolts until they come to rest on the shoulder.
●
Now remove the screw (33) and take off the pulley assembly with the hydraulic hoses.
●
Remove the pulley (50) and the lift chain from the top right hand side of the second mast stage.
3.
Lift the second mast stage into the first stage.
●
Remove the lift chains and the hoses from the bottom of the third mast stage.
4.
Lower the second mast stage into the first stage to leave an overlap of 455mm.
●
Check again if there are any connections which could be damaged when the third mast stage is lifted out.
5.
Using a crowbar press against the upper mast rollers of the second mast stage until it rests against the opposite roller in the mast channel.
●
Using the crane pull the third mast stage out from the top. Place the third mast stage on the ground.
6.
●
Attach a load sling to the cross member of the second mast stage.
Keep holding the crowbar under pressure and using a feeler gauge measure the distance between the edge of the roller and the mast channel.
●
Slightly raise the second mast stage. Remove the screw (30) in order to loosen the lift cylinder piston rod.
7.
●
Raise the second mast stage until the stop block at the top of the first mast stage can be accessed via the lower hole in the second mast stage.
●
Remove the stop block (4 to 8, 66).
●
Check again if there are connections which could be damaged when the second mast stage is lifted out.
Divide the reading by 2. The figure now obtained is the play that needs to be compensated for on each side of the mast by placing shims underneath a roller. Divide the measurement previously obtained by 0.76 to give you the number of shims needed to place under the mast rollers (the shims are 0.76mm thick). After inserting the shims the maximum residual play can be 0.76 mm.
8.
Repeat stages 5 to 7 on the lower mast roller.
9.
Lift the second mast stage out again and place the number of shims calculated in stages 7 and 8 underneath the mast rollers. It is important to use the same number of shims on either side.
●
Using the crane pull the second mast stage out from the top. Place the second mast stage on the ground.

If the mast has to be further dismantled, refer to Dismantling the Mast (Attached).
CAUTION Risk of injury from falling components. Using the crane, hold the cylinder and the mast assemblies at their centre of gravity and prevent the load slings from sliding off.
SC3200 03/2004 • Printed in Germany
MAST The procedure is practically identical to removing the mast components with the mast assembled. Only the crane movements are horizontal. You will therefore need a portal or gantry crane.
Mast Assembly Assemble the mast in the reverse order of the procedure in Mast Removal. Refit the mast bearings (Fig. MS-2232-011) and the corresponding number of shims on their original side. Torque the mast bearing mounting screws to 550 600 Nm. Apply liquid sealant part no. 060015-016 to the mast stopper (66) screws and torque to 122 - 149 Nm. Apply liquid sealant part no. 060017-014 to the lift cylinder mounting studs prior to assembly. Apply a thin layer of grease to the tilt cylinder bearing studs (2, Fig. MS-2232-012). For grease type see Lubricant table in Chapter 1.

MAST Inspection
Lift Chains General Lift chains are a major component of a fork lift truck. The chain system on this mast is designed to transmit the lift force from the hydraulic cylinder to the fork reliably and efficiently. Safe, uninterrupted truck operation depends on careful servicing and maintenance of the lift chains. Most complaints about the chain performance are due to lack of maintenance. Highly stressed precision chains require regular maintenance to ensure a long useful life.
The chain must be inspected every 100 hours for any signs of faults or damage. If used in a corrosive or dusty environment, this interval must be reduced to 50 hours. If this cannot be performed on the truck, the lift chains must be removed. Irrespective of the result of the inspection, the lift chains, detachable chain anchors and anchor bolts must be replaced after max. 6000 service hours or three years, whichever comes first. The inspection should include the following: ●
Chain wear and elongation.
●
Pitting due to rust or corrosion, in particular on the outer surfaces of the connection plates.
●
Pins turning in or extruding from the outside plates.
●
Loss of freedom of movement.
●
Damage to the anchor bolt attachment
●
Wear and corrosion to the anchor bolt and anchor.
●
Wear between the bolts and the connection plates.
The following sections cover the above items in detail.
Cleaning WARNING Never use chemical solvents or steam to clean the chains. The lubricant applied at the factory will be removed from the inner plate surfaces. The chain surface should be cleaned with paraffin, a hard bristle brush and lint-free cloth. After inspection apply another film of chain spray. The oil acts both as a lubricant and as an anti-corrosive protection.
Wear The chain bends as it passes over the chain rollers. This leads to a gradual wearing of the joints. Any slack a chain undergoes during its lifetime is due to wear to the links and the chain plate eyelet.

MAST DANGER
Freedom of Movement of Chain Links
When checking for chain wear be sure to measure a part of the chain which passes over the guide pulleys. Never repair chains by cutting out the worn section and replacing it with a new section. If a chain is worn, always replace both lift chains.
Each individual chain link must flex freely. Tight joints (Fig. 2775si) increase friction and the chain tension during lifting. Excessive chain tension in turn accelerates material wear.
Chain wear can be measured with a wear gauge (Crown No. 106440) or a steel tape measure (see Fig. 2271). Before testing the chain slack it is important to tension the lift chain if necessary. For non-detachable lift chains the weight of the fork carriage or mast is sufficient. If the lift chain is detached it must be kept taut during measurement. The chain slack test must cover at least ten links, over at least three different points in a section of the chain which always passes over a pulley during operation.
2775si
Possible causes of stiff joints are as follows: ●
Bent pins or plates
●
Rusty joints.
●
Peened plate edges.
Plate edge distortion is caused by: ●
Ruptured chain pinion.
●
Constant overloading of the chain.
●
Chain striking the mast components.
Immediately replace any chains with stiff joints.
Chain Tension
Centre Chain Dimensions (Dimension C in Fig. 2271). New:
10 links = 254 mm
Wear limit:
10 links = 262 mm
Outer Chain Dimensions New:
10 links = 190.5 mm
Wear limit:
10 links = 196 mm
When installed, both lift chains should have the same chain tension to ensure even distribution of the load over the two chains when lifting. When replacing the forks make sure that both forks lie evenly on the surface. If they are not even, compensate the chain length via the chain anchor so that both chains have the same chain tension. After adjusting, tighten the counternuts of the chain anchor again (for correct torques see Chapter 1, Torque table).
DANGER If just one of the faults mentioned in this chapter is detected, both chains together with their chain anchors or bolts must be immediately replaced. Never repair damaged chains! This can result in fatal accidents!

MAST Chain Anchor and Pulleys
Protruding or Turned Chain Pins DANGER
2774si
Never attempt to repair the chain by driving pins back into the chain. This can result in accidents with severe or even fatal injuries if the chain tears. Fit new chains.
In the course of checking the chain system, the chain anchors, chain bolts and pulleys must be checked for wear. On the chain anchor watch out for wear and cracking of the individual fingers. If one of the above problems occurs replace the chain anchor. Detachable chain anchors and anchor bolts must be replaced after max. 6000 service hours or three years, whichever comes first. Pulleys with heavily worn flanges and contact surfaces must be replaced. Worn flanges are due to misalignment. The chain tension and mast roller setting must be checked.
Worn Connection Plates Generally speaking, material wear is the cause of worn or missing connection plates. The plates near the chain pin hole (Fig. 2774si) can crack after a large number of lifting cycles with heavy loads. Replace both chains immediately if cracking shows or plates are missing.
2776si
Considerable frictional forces between the connection plates and the pins occur when lifting heavy loads with an insufficient or non-existent film of oil. In extreme cases the frictional torque in the joints can be such that the pins turn and gradually work out of the chain (Fig. 2776si). This can result in chain failure. Turned pins can be rapidly identified if the flat ends are not all pointing in the same direction. Chains with twisted or protruding pins must be replaced immediately.
Corrosion
2773si
The chains used on fork lift trucks are highly stressed precision components. It is particularly important to maintain the original fatigue strength throughout its useful life. Corrosion considerably reduces the capacity of a lift chain. It results in cracking in the side plates. Lift chains must therefore be protected from corrosion. The layer of grease applied in the factory hot dip galvanizing process is an excellent protection and fully penetrates the joints.
MS-7-2232

SC3200 03/2004 • Printed in Germany
MAST Do not remove this layer! After commissioning the chain supplement the factory lubrication through a regular lubrication schedule. Rust film on lift chains can be removed and neutralised by cleaning with chain oil. Always replace heavily corroded and rusting chains. The risk of cracking as a result of rust is too great.
Chain Lateral Wear Wear traces along a stretch of the chain on the pin heads and the outer plates indicate misalignment. This can have one of two causes: uneven chain tension or misalignment between the pulleys and the chain anchors. Uneven Chain Tension When fitting or adjusting the chains make sure that they are evenly charged. If for example the fork heel height or the platform height are changed, the chain anchors must be loosened until both forks touch the ground. Both chains must have equal amounts of air or tension at this point. The lower chain anchor nuts must be tightened by the same number of turns. When the required height has been reached, fix the setting with the top (chain side) lock nut and its respective lock washer. Misalignment of Lift Components Misalignment of the chain pinion and the chain due to the wrong number of washers on the mast or a damaged mast or cylinder components can also contribute to wearing of the chain sides. To test whether this is the case, proceed as follows: Place the truck on a horizontal surface in the service station. Support the fork carriage and detach both ends of the lift chain from the chain anchor and visually inspect the alignment with the anchor slots.

MAST Lift Chain Lubrication Lubrication is the most important factor in lift chain maintenance. It considerably affects the chain’s useful life. Highly stressed chains under constant use cannot last sufficiently long if they are not regularly lubricated within a planned maintenance schedule.
bolt (see Fig. 277si) and allow the oil to penetrate to the bearing surface on the chain bolt, even when the chain is dirty. In normal operating conditions the chains should be cleaned and immediately lubricated every 100 service hours. In extreme conditions this interval must be reduced accordingly.
As with all contact surfaces, the tensiled steel precision moving parts require a durable lubricant film between the contact surfaces to avoid excessive wear. Maintaining a lubricant film on all the chain surfaces provides the following benefits: ●
Restricts joint wear to a minimum (chain elongation)
●
Avoids corrosion
●
Reduces the risk of chain bolts turning
●
Restricts the danger of chain joints turning in to a minimum
●
Ensures an even movement of the chains and thus reduces noise levels
●
Reduces the chain tension due to less friction in the chain system
Oil film
Key factors when considering which lubricant to use are as follows: ●
High degree of penetration in the narrowest of gaps
●
Maximum tolerance of pressure and shearing forces before the lubricant film comes off.
●
Suitability to the operating temperature range, especially important for cold store trucks.
277si
You will find details of Crown approved chain oils in the Lubricant table in Chapter 1 of this manual. Lubrication intervals depend on the operating conditions and the environment. Trucks parked outdoors, in cold stores or which are subjected to extreme weather conditions must be lubricated more frequently. Dust will gather on oiled chains in dusty environments. However, even in these conditions, regular lubrication can considerably reduce wear. A paste mixture of oil and dirt will gather on the chain joints, but they will not wear as fast as they would if they were left to dry, leaving a metal to metal contact between the pins and plates. Note: A lift chain must never be allowed to dry. In dusty operating conditions the multi-plate chains can be more efficiently lubricated than roller chains. Multi-plate chains consist of several plates. Therefore they provide several paths for the lubricant to reach the chain MS-7-2232

CYLINDERS Tilt Cylinders General
Removal INFORMATION Always leave one tilt cylinder installed!
Make sure the components and the working area are clean. Thoroughly clean the tilt cylinder before dismantling it. Hydraulic systems are sensitive to contamination.
If both tilt cylinders have to be repaired on a truck, first remove one cylinder, repair it and then install it again. Then remove the second cylinder for repair and refit it.
When carrying out repairs, always replace all the seals and bearing rings. Apply a thin layer of hydraulic oil to all the seals and internal metal surfaces prior to assembly. Use hydraulic oil according to the temperature range of the area of application (see Lubricant table in Chapter 1). Various tilt angles are possible depending on the truck model. The key factors in deciding the tilt angle are the spacer bushings (9 and 17, Fig. MP-2232-031). When ordering spare parts refer to the parts table in the spare parts catalog.
If both tilt cylinders were to be removed at the same time, you would need and inclinometer and a horizontal surface to re-adjust the mast tilt angle with a tolerance of 15 angular minutes. ●
Tilt the mast fully forward (the tilt cylinders must be fully extended). The mast must remain at this angle until the tilt cylinder is re-installed.
●
Disconnect the battery and depressurise the hydraulic system (see Chapter 7 Mast).
●
Remove the screw (6, Fig. MP-2232-031) and the safety plate (5, MP-2232-031) from the clevis of one of the tilt cylinders.
●
Remove the screw (6) and pull the retaining pin (27, MP-2232-031) out of the bearing stud (26, MP-2232-031).
CAUTION Possible damage! Do not drive the bearing studs in or out. Any knocks will damage the studs and the bearings and will distort the forks on the cylinder tube and the clevis. Push or pull the studs with a suitable tool. While doing so, ensure that the tool is supporting the opposite side of the fork.
