Service Manual

SKID-STEER LOADERS

INTRODUCTION With correct maintenance and proper use, the Gehl V270/V330 and Mustang 2700V/3300V skid-steer loaders will give years of dependable service. This service manual is intended to be a guide in the assembly and disassembly, installation and removal, adjustment and testing, troubleshooting and replacement of components that together make up the Gehl V270/V330 and Mustang 2700V/3300V skidsteer loaders.

In many of the procedures found within, the installation steps are the exact opposite of the removal steps, and therefore the opposite procedure is not written. Instead, a note to reverse the procedure is stated. This reduces redundancy and excessive pages in the manual. In cases though, where the assembly and disassembly or removal and installation procedures differ, and additional steps or safety concerns are paramount, the entire reverse procedure is written to include the additional information.

The Table of Contents and the Index can be used to make finding a procedure easier. Many schematics, photographs and line art drawings are used to help perform the necessary repairs, tests and adjustments that the skid-steer loader needs to keep it in good running condition.

If you have any questions, please contact your authorized Gehl or Mustang dealer, or call the Gehl and Mustang Service Department for assistance.

SAFETY

Signal Words

DANGER “DANGER” indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury.

General Information The above safety alert symbol means: ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED! It stresses an attitude of “safety awareness” and can be found throughout this service manual and on decals on the machine.

Before operating or working on this machine, read and study the following safety information. In addition, be sure that everyone who operates or works on this equipment is familiar with these safety precautions. It is essential to have competent and careful operators, who are not physically or mentally impaired, and who are thoroughly trained in the safe operation of the machine and the handling of loads. It is recommended that the operator be capable of obtaining a valid motor vehicle operator’s license.

The use of skid-steer loaders is subject to certain hazards that cannot be eliminated by mechanical means, but only by exercising intelligence, care and common sense. Such hazards include, but are not limited to, hillside operation, overloading, instability of the load, poor maintenance and using the equipment for a purpose for which it is not intended or designed.

Both Gehl and Mustang Company ALWAYS consider the operator’s safety when designing machinery and guards exposed moving parts for the operator’s protection. However, some areas cannot be guarded or shielded in order to assure proper operation. The Operator’s Manual and the decals on the machine warn of additional hazards and should be read and observed closely.

These topics in the Safety chapter of the service manual include procedures, which, when followed, will allow safe performance of service procedures: Mandatory Safety Shutdown Procedure, Lift Arm Support Device, Roll-Over Protective Structure (ROPS/FOPS)/Falling Object Protective Structure (FOPS) Lock Mechanism, Loader Raising and Lowering Procedures, and Relieving Hydraulic Pressure.

PRINTED IN USA

WARNING “WARNING” indicates a potentially hazardous situation, which, if not avoided, could result in death or serious injury.

CAUTION “CAUTION” indicates a potentially hazardous situation, which, if not avoided, may result in minor or moderate injury. May also alert against unsafe practices.

Additional Safety Reminders Read and understand the Service Manual and all decals before maintaining, adjusting or servicing this equipment.

Doors, Guards and Shields - Some photographs in this manual may show doors, guards and shields open or removed for illustrative purposes only. BE SURE all doors, guards and shields are in their proper operating positions before starting engine to operate unit.

Damaged or Worn-out Parts - For safe operation, replace damaged or worn-out parts with genuine Gehl/ Mustang service parts, before operating this equipment.

Attachments - Gehl and Mustang loaders are designed and intended to be used only with Gehl/Mustang Company attachments or approved referral attachments.

The Company cannot be responsible for safety if the loader is used with a non-approved attachment.

Battery Safety - To avoid injury from a spark or short circuit, disconnect the negative battery cable before servicing any part of the electrical system. Do not tip the battery more than 45º.

SAFETY

GEHL V270 and V330 / MUSTANG 2700V and 3300V

Loader Stability - A skid-steer loader’s stability is determined by its wheelbase and tread width. The following elements can affect stability: terrain, speed, load being carried or dumped, and sudden control movements. DISREGARDING ANY OF THESE FACTORS CAN CAUSE THE LOADER TO TIP, POSSIBLY RESULTING IN DEATH OR SERIOUS INJURY. Therefore, ALWAYS have the operator restraint bar lowered and wear the seat belt. Operate the controls only from the operator’s seat. Operate the controls smoothly and gradually at an appropriate engine speed that matches the operating conditions.

DO NOT exceed the rated operating capacity of the machine. For additional stability when operating on inclines or ramps, ALWAYS travel with the heavier end of the loader toward the top of the incline.

ALWAYS look to the rear before backing up.

When parking machine, before leaving seat, check restraint bar for proper operation. The restraint bar, when raised, applies the parking brake and deactivates lift/tilt controls and auxiliary hydraulics.

Keyswitch - NEVER attempt to bypass the keyswitch to start the engine. Use the jump-starting procedure detailed in the Service chapter of the Operator’s Manual.

Hydraulic Fluid Leaks - NEVER use hands to search for hydraulic fluid leaks.

Instead, use paper or cardboard. Fluid under pressure can be invisible, penetrate the skin and cause a serious injury. If any fluid is injected into skin, see a doctor at once. Injected fluid MUST be surgically removed by a doctor or gangrene may result.

Wear Safety Glasses - ALWAYS wear safety glasses with side shields when operating the machine or striking metal against metal. In addition, it is recommended that a softer (chip-resistant) material be used to cushion the blow. Failure to heed could lead to serious injury to eyes or other parts of the body.

ALWAYS wear safety glasses when searching for hydraulic leaks or when working near batteries.

Loaded Bucket/Fork - DO NOT raise or drop a loaded bucket or fork suddenly. Abrupt movements under load can cause serious loader instability.

NEVER push the lift control into the “float” position with the bucket or attachment loaded or raised, because this will cause the lift arm to lower rapidly.

strength to support the weight of the loader and the load.

DO NOT smoke or have any spark-producing equipment in the area while filling the fuel tank or while working on the fuel or hydraulic systems.

Exhaust Gases - Exhaust fumes can kill. DO NOT operate this machine in an enclosed area unless there is adequate ventilation.

Engine - NEVER use ether or starting fluid.

People - NEVER carry riders. DO NOT allow others to ride on the machine or attachment, because they could fall or cause an accident.

BE SURE all persons are away from the machine and warn others in the area before starting the engine.

ALWAYS face the machine and use handholds and steps when getting on and off. DO NOT jump off machine.

Wear appropriate ear protection for prolonged exposure to excessive noise.

ALWAYS perform a daily inspection of the machine before using it. Look for damage, loose or missing parts, leaks, etc.

Remove trash and debris from the machine and engine compartment each day to minimize risk of fire.

New operators MUST operate loader in an open area away from bystanders. Practice with controls until the loader can be operated safely and efficiently.

Mandatory Safety Shutdown Procedure BEFORE cleaning, adjusting, lubricating or servicing the unit or leaving it unattended: 1. Move drive control handle(s) to the neutral position.

2. Lower the lift arm and attachment completely. If the lift arm must be left in the “raised” position, BE SURE to properly engage the lift arm support device.

3. Move the throttle to the low idle position, shut off the engine and remove the key.

4. Before exiting, move the lift/tilt control(s) to verify that controls do not cause movement of the lift arm or hitch.

Only after these precautions can you be sure it is safe to proceed. Failure to follow the above procedure could lead to death or serious injury.

DO NOT drive too close to an excavation or ditch. BE SURE that the surrounding ground has adequate 4

Lift Arm Support Device Engagement 1. Raise the lift arm fully.

2. Turn keyswitch to OFF position to stop engine.

WARNING BEFORE leaving operator’s compartment to work on the loader with the lift arm raised, ALWAYS engage the lift arm support device.

Turn the keyswitch to OFF, remove the key and take it with you.

Many service procedures require a raised lift arm to allow easier access to loader components. For operator and service personnel safety, a lift arm support device is standard on Gehl and Mustang skid-steer loaders. Used as a cylinder block, it helps prevent a raised lift arm from unexpectedly lowering.

3. Have an assistant remove the lift arm support device from its storage location and place the lift arm support device on either the left or right cylinder rod..

Clamping Knob

BE SURE to engage the lift arm support device whenever the lift arm is raised. When the device is not being used, secure it to the right side timing link on the lift arm using the clamping knob provided.

The lift arm support device is a safety device which must be kept in proper operating condition at all times.

The following procedures outline the correct way to engage and disengage the lift arm support device.

4. Restart the engine.

5. Slowly lower the lift arm until the support device contacts the top end of the lift cylinder.

Loader Raising Procedure

Loader Lowering Procedure

The following procedure is used to raise the skid-steer loader so that all four tires are off the ground.

When the service procedures are complete, the skidsteer loader can be taken down from the “raised” position. To lower the loader onto its tires: 1. Using a jack or hoist, raise the loader until its weight no longer rests on the reinforced pallet, jack stands (or blocks).

WARNING BEFORE servicing the machine, exercise the “Mandatory Safety Shutdown Procedure” described in this chapter.

2. Carefully remove the reinforced pallet, jack stands (or blocks) under the loader.

3. Slowly lower the loader until the tires are on the ground.

WARNING DO NOT rely on a jack or hoist to maintain the “raised” position without additional blocking and supports. Serious personal injury could result from improperly raising or blocking the skid-steer loader.

1. To raise and block the skid-steer loader, obtain four jack stands (or blocks) of sufficient strength and stability to support the loader.

2. Using a jack or hoist capable of raising the fullyequipped loader, lift the loader until the tires are off the ground.

3. Place the jack stands (or blocks) under the flat part of the loader chassis. Place them parallel with, but not touching, the tires.

4. Slowly lower the loader so that its weight rests on the jack stands (or blocks).

5. When the procedure is finished, all four tires will be off the ground, and the wheels can be removed as necessary.

Drive Chain Adjustment Skid-steer loader drive chain tension should be checked every 250 hours of operation.

5. To adjust chain tension, loosen the eight locknuts on the two axles on one side of the loader. Using a spreader bar, push the axles outward in their slots to tighten the chain.

Adjustment Procedure

WARNING BEFORE beginning this service procedure, perform the following SAFETY procedures: • Shut off the engine.

• Raise and securely block the loader so all four tires are off the ground.

(For detailed instructions, refer to the Safety chapter of this manual.)

1. Remove the wheels and tires on the side of the loader to be serviced.

2. Remove 14 machine screws on the chaincase access cover (between tires) to access the drive chain.

6. After the proper chain tension is obtained, retighten the locknuts on the axle. Axle housing locknuts should be torqued to 280 lbf. (380 N•m).

IMPORTANT: The drive chain must have a minimum of 1/2" (13 mm) deflection; overtightening causes premature drive chain and sprocket wear.

7. Scrape off the old oil-resistant RTV and apply new RTV. Reinstall the access cover.

Introduction This chapter covers the removal, installation, assembly and adjustment procedures for standard and optional controls on Gehl V270/V330 and Mustang 2700V/3300V model skid-steer loaders.

Equipment Identification Because there are a variety of control options available for Gehl V270/V330 and Mustang 2700V/3300V models, it is necessary to properly identify the controls before beginning the service procedures. Illustrations and photographs are provided with procedures to aid in servicing this equipment.

Hand/Foot Controls On loaders with “Hand/Foot controls,” left and right drive control handles operate independently of each other.

Pushed forward together causes the loader to move forward, but pushing either one farther forward than the other and the loader turns. Separate foot pedals control lift and tilt functions of lift arm and attachment. Engine speed is controlled with a hand throttle dial located in the right instrument panel. A yellow rocker switch in the right control handle controls standard auxiliary hydraulics in tandem with a (red) lock-on button switch. On high-flow models, a rocker switch in the left instrument panel activates the high-flow hydraulics.

Dual Joystick Controls On loaders with "Dual Joystick controls," the left control handle operates the drive wheels, and the right control

CONTROLS

handle operates lift and tilt functions of the lift arm and attachment. Engine speed is controlled with a foot throttle pedal and dial in the right instrument panel. A yellow rocker switch in the right control handle controls standard auxiliary hydraulics in tandem with a (red) lock-on button switch. On high-flow models, a rocker switch in the left instrument panel activates the high-flow hydraulics.

Float Control The float control on skid-steer loaders is controlled by a momentary button switch in the right control handle, which lights a panel indicator light.

Two-Speed Control (Optional) Skid-steer loaders with this option have a high and low speed setting. It is controlled by a button switch in the left control handle, which lights a panel indicator light.

Hydraglide™ Ride Control The Hydraglide™ Ride Control is controlled by a button switch in right control handle, which lights a panel indicator light.

Power-A-Tach® (P-A-T) Hitch Control (Optional) The Power-A-Tach hitch control on skid-steer loaders is controlled by two safety switches. In the left instrument panel is a two-position momentary switch to energize the system. Then, in the right instrument panel, is a threeposition momentary button to actuate the P-A-T hitch.

The energizing switch drops the hydraulic pilot pressure and applies the parking brake. While holding the energizing switch, the actuating switch can then be applied to latch (extend) or unlatch (retract) the hitch pins.

Introduction This chapter covers troubleshooting, testing, removal, installation and adjustment procedures for hydraulic system components on Gehl V270/V330 and Mustang 2700V/3300V model skid-steer loaders.

Power for the lift arm functions and auxiliary hydraulics is provided by a gear pump attached to the front of the tandem pump.

Standard and high-flow models include a standard-flow auxiliary hydraulics system with connections on the lift arm for attachment hookup. High-flow models are equipped with high-flow hydraulics, which includes connectors on the right side of the lift arm, for operating attachments that require higher hydraulic flow.

Information on recommended hydraulic fluids, capacities and filter change intervals is in the Lubrication chapter. For detailed information on gear pump or control valve internal repair, consult the GehlMustang Service Department and/or the hydraulic component manufacturer’s service manual. Hydraulic components related to the drive system are covered in the Hydrostatic System chapter.

HYDRAULIC SYSTEM

The following troubleshooting guide lists potential hydraulic system problems, as well as possible causes and remedies, for Gehl V270 and Mustang 2700V skidsteer loaders.

If you cannot locate a particular hydraulic system problem in this chart, consult the Hydrostatic System chapter troubleshooting chart or call a Service technician.

When a problem occurs, don’t overlook simple causes.

A malfunction could be caused by something as simple as low fluid level in the hydraulic reservoir. After a mechanical failure has been corrected, be sure to locate the cause of the problem.

IMPORTANT DO NOT attempt to service or repair major hydraulic system components, such as the gear pump, unless authorized to do so by your Gehl or Mustang dealer. Any unauthorized repair will void the warranty.

HYDRAULIC SYSTEM

GEHL V270 and V330 / MUSTANG 2700V and 3300V

Pressure Tests, Control Valve The control valve on the skid-steer loader controls lift and tilt functions of the lift arm and standard and highflow auxiliary hydraulics. It is located on the right side of the chassis. The relief valve(s) inside the control valve can be tested at the lift arm couplers.

Test Procedure The hydraulic oil must be at normal operating temperature.

5. Have assistant observe the pressure reading on the gauge. The pressure reading on the loader should be: a. for standard flow, at least 3250 PSI (224 bar), but NOT more than 3350 PSI (231 bar), and b. for high-flow, at least 3150 PSI (217 bar), but NOT more than 3250 PSI (224 bar).

6. If the pressure reading is NOT between the specified pressures, adjust pressure as follows:

WARNING

WARNING BEFORE beginning this service procedure, perform the following SAFETY procedures:

BEFORE continuing this service procedure, perform the following SAFETY procedures:

• Shut off the engine.

• Shut off the engine.

• Relieve hydraulic system pressure.

• Lower the lift arm.

(For detailed instructions, refer to the Safety chapter of this manual.)

• Set the hydraulic auxiliary to the detent position.

• Tilt back ROPS/FOPS until lock engages.

NOTE: To prevent contamination, ALWAYS clean the area around hydraulic fittings before disconnecting any hydraulic plug, hose or tube.

(For detailed instructions, refer to the Safety chapter in this manual.)

1. What you’ll need: an assistant and a minimum 5000 psi (345 bar) pressure gauge.

a. Remove the cap on the relief valve adjuster screw(s). The high-flow relief valve is located at the top rear area of the control valve. Standard auxiliary relief valve is beneath the high-flow relief valve at the bottom rear of the control valve.

2. Perform the pressure tests at the auxiliary hydraulic couplers located on the left lift arm and the highflow couplers (if so equipped) located on the right lift arm of high-flow auxiliary loaders.

Relief Valves Standard Auxiliary Couplers

3. Install the pressure gauge in the end of the male coupler and set the auxiliary hydraulic circuit to the detent position.

4. Slowly increase the engine speed to HIGH IDLE.

HYDRAULIC SYSTEM

Tilt Cylinder Test If the bucket (or attachment) drifts down with the tilt control in the NEUTRAL position, first check the tilt cylinders for external leakage. If external leakage is evident, a new seal kit should be installed in the leaking cylinder(s). If no external leakage is evident, check the tilt cylinders for internal leakage according to the following procedure.

NOTE: When checking for drifting, BE SURE the ignition key is in the ON position, with the operator in the seat, and the restraint bar lowered. The maximum allowable tilt cylinder circuit drifting with a loaded bucket is 0.4" (10 mm) of cylinder extension in 15 minutes.

Test Procedure

c. First, set the standard flow. Repeat steps 4 and 5.

Turn the adjuster screw to achieve the desired setting.

WARNING

d. Next, set the high-flow. Repeat steps 4 and 5.

Turn the adjuster screw to achieve the desired setting.

BEFORE beginning this service procedure, perform the following SAFETY procedures:

e. Recheck the standard flow setting.

• Shut off the engine.

• Relieve hydraulic system pressure.

(For detailed instructions, refer to the Safety chapter of this manual.)

1. Load the bucket and allow it to rest on the ground.

IMPORTANT: To prevent contamination, ALWAYS clean the area around hydraulic fittings before disconnecting any hydraulic hose or tube.

2. Checking one tilt cylinder at a time, remove the lower hydraulic hose from the cylinder being tested, and cap or plug the hose and cylinder port.

Caps/plugs MUST BE able to withstand full hydraulic pressure.

HYDRAULIC SYSTEM

GEHL V270 and V330 / MUSTANG 2700V and 3300V Self-Leveling Valve Test

WARNING

Test Procedure

BEFORE raising a loaded bucket, BE SURE no personnel are near the loader. Serious personal injury can result if bucket drops suddenly or its contents spill out.

3. Climb back into the operator’s seat, lower the restraint bar, and start the engine.

4. Raise the lift arm enough for the bucket (or attachment) to clear the ground.

5. Shut off the engine, turn the ignition key to the ON position (engine OFF) and operate the tilt control in both directions.

6. If the bucket drifts, the blocked tilt cylinder has leaking piston seals. If it DOES NOT drift, lower the lift arm and reconnect the hydraulic hose to the cylinder. Then test the other tilt cylinder in the same way, repeating steps 2-5.

WARNING BEFORE beginning this service procedure, perform the following SAFETY procedures: • Shut off the engine.

• Relieve hydraulic system pressure.

(For detailed instructions, refer to the Safety chapter in this manual.)

1. With the engine OFF and the ROPS raised and locked, loosen the jam nut on the self-leveling valve adjuster screw.

Self-Leveling Valve Adjuster Screw

7. After both tilt cylinders have been tested, be sure the hydraulic hoses are reconnected.

NOTE: If both tilt cylinders have good seals, and the bucket still drifts, the fault could be in either the control valve or the self-leveling valve. Continue the test procedure with step 8, below. Also, refer to the Troubleshooting Guide in this chapter.

8. To determine if either the control valve or self-leveling valve is faulty and causing the bucket to drift, perform the “Self-Leveling Valve Test” procedure in this chapter.

NOTE: For step 2, BE SURE to count and record the number of turns, so the adjuster screw can be returned to its original setting after the test.

2. With an allen wrench, turn the adjuster screw in (clockwise) until it bottoms out. The self-leveling valve is now disabled and will not affect the tilt operations.

3. Perform steps 3-5 in the “Tilt Cylinder Test” procedure. If the bucket no longer drifts, the self-leveling valve is defective. If the bucket continues to drift, the control valve is defective and in need of repair or replacement.

4. Refer to the “Self-Leveling Valve Adjustment” procedure in this chapter for correct adjustment of the self-leveling valve.

If no external leakage is evident, check the lift cylinders for internal leakage according to the following procedure.

HYDRAULIC SYSTEM

4. Install a plug on the hydraulic tube. Attach a hose to the rod end port of the cylinder and run the other end of the hose into a suitable container.

5. Climb into the operator’s seat, lower the restraint bar and start the engine.

6. Hold the lift control in the RAISE position. If the seals in the cylinder are defective and leaking, oil will flow out of the rod end port.

NOTE: When checking lift arm for drifting, BE SURE the ignition key is in the ON position, with the operator in the seat, and the restraint bar lowered. The maximum allowable lift cylinder drifting is 0.75" (19 mm) of cylinder retraction in 15 minutes.

7. Slowly lower the lift arm until the support device contacts the lift cylinder. Shut off the engine and relieve hydraulic pressure with the lift control.

Test Procedure

9. The other cylinder can be checked the same way.

1. Remove the bucket or attachment from the attachment bracket.

NOTE: If neither lift cylinder shows signs of external or internal leakage, and the lift arm still drifts, the problem could be due to leaking hydraulic tube fittings between the control valve and the lift cylinders. Check all hydraulic tube fittings thoroughly. The fault could also be in either the control valve or the ride control manifold. Continue the test procedure with step 10.

Also refer to the Troubleshooting Guide in this chapter.

WARNING BEFORE continuing this service procedure, perform the following SAFETY procedures: • Raise lift arm; engage lift arm support device.

• Shut off the engine.

• Relieve hydraulic system pressure.

8. Reconnect the tube to the cylinder, then reattach the clamp around the hydraulic tube and cylinder.

10. Relieve hydraulic pressure. Disconnect the ride control tubes to port A & B of the ride control manifold. Cap the fittings on the hydraulic tubes in the chassis, near the battery.

(For detailed instructions, refer to the Safety chapter in this manual.)

2. Remove the clamp securing the hydraulic tubes to the lift cylinder on the side being tested.

IMPORTANT: To prevent contamination, ALWAYS clean around hydraulic fittings before disconnecting any hydraulic lines.

3. Disconnect the hydraulic tube from the rod end port of the lift cylinder to be tested.

11. Raise the lift arm and check for drifting.

12. If drifting has subsided, then the solenoid valve nearest port A of the ride control manifold should be replaced.

13. If drifting remains after disconnecting the ride control manifold, then the control valve is at fault and should be replaced.

HYDRAULIC SYSTEM

GEHL V270 and V330 / MUSTANG 2700V and 3300V

Solenoid Valve Test - Joystick Drive Supply, Brake, Two-Speed Brake and Ride Control During normal operation, the Hydraglide™ solenoid valve provides two functions: a float function for the lift arm and a ride control function for the lift arm. The float function allows the bucket to follow the contours of the ground during back-dragging applications. The ride control function is a cushioning effect for the lift arm when driving over uneven surfaces.

During normal operations, the joystick drive supply and brake valves should prevent operation of the drive functions if any of the safety interlock system switches are open, for example: » Operator not sitting on the seat. » Restraint bar not lowered.

Joystick Drive Supply, Brake and Two-Speed Brake Test Procedure 1. Climb into the operator’s seat, lower the restraint bar and start the engine.

2. BE SURE the parking brake switch on the instrument panel is in the OFF position.

3. Raise the restraint bar. Use the drive controls (one at a time) to see if the tires will move. » If the skid loader moves forward or backward, the joystick drive supply or brake solenoid is malfunctioning.

Use a piece of cardboard or paper. Escaping fluid under pressure can be invisible and penetrate the skin causing serious injury. If any fluid is injected into your skin, see a doctor at once. Injected fluid MUST be surgically removed by a doctor familiar with this type of injury or gangrene may result.

1. Secure the control valve to the welded bracket with four locking capscrews. If straight or 90° fittings are not in the valve, install them at this time.

2. Ports 10 and 11: Connect four hoses to straight fittings on the control valve, two hoses in front and two in the rear.

3. Port 9 (high-flow only): Connect the pressure hose to the 90° fitting on the control valve (other end connects to gear pump).

WARNING ALWAYS wear safety glasses when checking for hydraulic fluid leaks. Escaping fluid under pressure can be invisible and can cause permanent eyesight damage if safety glasses are not worn.

4. Port 8: Connect a lift, tilt and auxiliary tube to the straight fittings on the control valve.

5. Port 7: Connect a lift, tilt and auxiliary tube to the straight fittings on the control valve.

6. Port 6: Connect the pressure hose to the straight fitting on the control valve (other end connects to gear pump).

7. Port 5: Connect the auxiliary return tube and highflow return tube (high-flow only) to straight fittings on the control valve.

8. Port 4: Connect the auxiliary feed tube and highflow feed tube (high-flow only) to straight fittings on the control valve.

9. Port 3: Connect the hydraulic filter tube to the straight fitting on control valve.

10. Ports 1 and 2 (high-flow only): Connect the highflow tubes at the straight fittings on the valve.

Electrically-controlled Standard Auxiliary Hydraulic Flow System Test and Operation The standard auxiliary hydraulics flow is controlled by the slider and trigger switch in the right control handle.

The control handle contains an integrated circuit that controls the signal to two proportional solenoid valves (a 3-bank or 5-bank) located on the right chaincase in the chassis.

Troubleshooting Test 1. The seat switch is compressed, the restraint bar is down and raise the ROPS/FOPS as described in the Operator’s Manual.

2. Check the auxiliary control fuse in the fuse box panel.

3. Check the diode and micro-relay in the power distribution panel.

4. Check connections at the control handle and coils.

5. Be sure that the interlock control module is outputting a signal for the hydraulic solenoid safety relay.

• The relay will actuate only with the keyswitch in the “ON” position, the restraint bar down and the seat switched closed.

6. Using a volt/ohm multimeter or a test lamp, probe the two wires going into pin 1 and pin 2 of the coil.

DO NOT disconnect the plug. If the plug is disconnected the controller will shut down.

Standard Aux Flow Controls

• The solenoid will actuate only with the keyswitch in the “ON” position, the restraint bar down and the seat switched closed. If the solenoid is unplugged, plug it back in and turn the keyswitch to “OFF,” wait two seconds and then turn the keyswitch to the “ON” position to reset the circuit.

Standard Flow Coils - 3-Bank Valve

• Monitor the voltage between pin 1 and pin 2 while operating the slider switch. With the help of an assistant, apply pressure to the operator’s seat and actuate the slider switch. The voltage should vary between 5.5 volts and 7.0 Volts.

Standard Flow High-Flow

• The coil resistance can be checked as well and should read 5.4 ohms ().

High-Flow Auxiliary Rocker Switch

ELECTRICAL SYSTEM

Troubleshooting Test 1. The seat switch is compressed, the restraint bar is down and raise the ROPS/FOPS as described in the Operator’s Manual.

2. There are indicators on the high-flow module to aid in diagnosis. Have an assistant actuate the rocker switch and monitor the indicators on the module.

This will provide direction on what to troubleshoot.

3. Check the auxiliary control fuse in the fuse box panel.

4. Check the electrical connections at the 5-bank proportional solenoid valve.

5. Be sure that the interlock module is outputting a signal for the hydraulic solenoid safety relay.

• The relay will actuate only with the keyswitch in the “ON” position, the restraint bar down and the seat switched closed.

6. Using a test lamp, probe the wire going into pin 1 of the coil. DO NOT disconnect the plug. If the plug is disconnected the controller will shut down.

High-Flow Control Module

• The solenoid will actuate only with the keyswitch in the “ON” position, the restraint bar down and the seat switched closed. If the solenoid is unplugged, plug it back in again and turn the keyswitch to “OFF,” wait two seconds and then turn the keyswitch to the “ON” position to reset the circuit.

• With the help of an assistant, apply pressure to the operator’s seat and actuate the high-flow switch. The light will be dimmer than normal due to reduced voltage in this circuit.

7. The coil resistance can be checked as well and should read 5.4 ohms ().

Troubleshooting Guide

Introduction This chapter covers troubleshooting, removal, installation, and adjustment procedures for engine components on Gehl V270/V330 and Mustang 2700V/ 3300V model skid-steer loaders. The primary engine system components are shown on following pages.

They are equipped with a Yanmar 4TNV98 turbocharged diesel engine. The four-cylinder engines are 202 cubic inch displacement (3,31 L) engines. The turbo engine compression ratio is 18.5:1. The fourcylinder engines are direct injection four-stroke engines with a firing order of 1, 2, 3, 4.

A “full-flow” oil filter is used in the lubrication system.

As with any engine, clean oil, fuel and air are critical to satisfactory performance and long engine life. If properly maintained, this engine can be expected to provide thousands of hours of trouble-free operation.

When ordering engine parts, always check the Gehl or Mustang Parts Manual to see if a special part has been fitted to the engine. If Gehl or Mustang parts are required, they can be ordered from Gehl Company.

The following troubleshooting guide lists potential engine problems, as well as possible causes and remedies, for Gehl V270/V330 and Mustang 2700V/ 3300V model skid-steer loaders.

When a problem occurs, don’t overlook simple causes.

A malfunction could be caused by something as simple as an empty fuel tank. After a mechanical failure has been corrected, be sure to locate the cause of the problem. For further troubleshooting information, refer to the engine manufacturer’s manual.

IMPORTANT DO NOT attempt to service or repair major components, such as the fuel injector pump, unless authorized to do so by your Gehl or Mustang dealer. Any unauthorized repair will void the warranty.

Troubleshooting Guide Problem Starter will not engage when keyswitch is turned to “START”.
