Workshop Manual Print No. 604.13.517.00 English

THIS ALERT SYMBOL SIGNALS IMPORTANT MESSAGES INVOLVING YOUR SAFETY. Read and heed carefully the safety instructions listed and follow the precautions recommended to avoid potential risks and to safeguard your health and your safety. You will find this symbol in the text of this Manual referred to the following key words: WARNING - Cautions directed to avoid improper repair interventions involving potential consequences for the safety of the personnel performing the repairs. DANGER - These warnings qualify specifically potential dangers for the safety of the operator or other persons directly or indirectly involved.

IMPORTANT NOTICE All maintenance and repair interventions explained in this Manual must be performed exclusively by the Service Organisation of the Manufacturer, observing strictly the instructions explained using, whenever necessary, the recommended specific tools. Whoever performs the operations reported without following exactly the precautions is responsible on his own, for the damages that may result. Neither the Factory nor any Organisations in its Distribution Network, including but not limited to national, regional or local distributors, are responsible for any liability arising from any damage resulting from defects caused by parts and/or components not approved by the Factory for use in maintaining and/or repairing products manufactured or merchandised by the Factory. In any case, no warranty of any kind is made or shall be imposed with respect to products manufactured or merchandised by the Factory, when failures are caused by the use of parts and/or components not approved by the Factory.


AVOID ACCIDENTS Most accidents, whether they occur in industry, on the farm, at home or on the road, are caused by the failure of some individuals to follow simple and fundamental safety rules and precautions. For this reason MOST ACCIDENTS CAN BE PREVENTED by recognising the real cause and doing something aboiut it before the accident occurs. Regardless of the care used in the design and construction of any type of equipment, there are many conditions that cannot be completely safeguarded against without interfering in the reasonable accessibility and efficient operation. A carefull operator is the best insurance against an accident. The complete observance of one simple rule would prevent many serious accidents. The rule is simple: never attempt to clean, lubricate or maintain a machine while it is in motion.

WARNING Prior to engaging in any maintenance, adjustment or repair operation on machines having hydraulically, mechanically, and/or cable controlled equipment (such as shovels, loaders, dozers, excavators etc.) be certain the equipment is lowered to the ground. If it is necessary to have the equipment partially or fully raised to gain access to certain items, be sure the equipment is suitably supported by means other than the devices used for controlling the equipment.

- If engine has a tendency to stall for any reason under load or idle, report this for adjustment to proper maintenance authority immediately. Do not continue to operate machine, until condition has been corrected.

Choose and shift into the most appropriate gear to keep the speed required, thus preventing any loss of control. - Do not operate machinery in a condition of extreme fatigue or illness. Be especially careful towards the end of working shift.

- On machines supplied with suction radiator fans, be sure to periodically check engine exhaust parts for leaks, as exhaust fumes are dangerous to the operator.

- Do not operate machine with brakes out of adjustment.

- In case of closed type cabs, always keep an opening with the outside, to ensure a constant air circulation.

- Operate the machine at speeds slow enough to ensure complete control at all times.

- Operators must know thoroughly the performances of the machine they are operating. When working on slopes or near sudden level drops of the terrain, avoid areas where ground is loose or soft since rolling-over or loss of control of machine could result.

- Travel slowly over rough terrain, on slopes or near drop-offs, in congested areas or on ice or slippery surfaces. - When backing, always look to where the machine is to be moved. Be alert to the position of exposed personnel. DO NOT OPERATE if exposed personnel enter the immediate work area. STOP THE MACHINE.

- Where noise exposure exceeds 90 dBA for 8 hours, wear approved ear protection.

- Maintain a safe distance from other machines. Provide sufficient clearance for ground and visibility conditions. Yield right-of-way to loaded machines.

- When counterweights are provided, do not work machine if they have been removed. - Overtaking manoeuvres must be performed only when absolutely necessary and unavoidable. Beware of possible uneven terrains, poor visibility conditions, the presence of other machinery or persons out of sight.

- Maintain clear vision of areas of travel or work. Keep cab windows clean and repaired. - When machines are operating in tandem, the pusher (rear) must be equipped with the appropriate deflectors to protect the unit in front from the air stream coming from the radiator.

- Operate the machine at a speed adequate to the working conditions in the site and slow enough to ensure complete control at all times.

SAFETY RULES

- NEVER DRIVE OVER THEM or other surface irregularities that brake traction with the ground, especially when on slopes or near drop-offs.

- Be alert of people in the operating area of the machine. - When operating a machine, know in advance what clearances will be encountered, overhead doors, cables, pipes, bearing load limitations of ground, bridges, floors or ramps.

- Be alert to avoid changes in traction conditions that could cause loss of control. DO NOT DRIVE on ice or frozen ground conditions when working the machine on steep slopes or near drop-offs.

- When roading, find-out what conditions are likely to be encountered, clearances, traffic congestion, type of road surfacing, etc. Beware of fog, smoke or dust elements that obscure visibility.

- Working in virgin and rough terrains is characterised by the presence of all the perils and risks listed above. In these conditions, it is emphasised the danger represented by large tree limbs (possibly falling on the machine), large roots (acting as a leverage under the machine when up-rooted causing the roll-over of the unit) etc..

- When crossing gullies or ditches, move at an angle with reduced speed after ensuring ground conditions will permit a safe traverse. - Explore the working area to identify potential risks such as: slopes, overhangs, pits, demolition rubble, fires, ravines, ditches, soft terrain, heavy traffic, crowded parking areas, closed ambients. In such conditions, proceed with extreme care.

STOPPING - When the machine is stopped for whatever reason, follow the instructions of chapters "Stopping the machine" and "Stopping the engine" of the Operation and Maintenance Instruction Manual.

- Whenever possible, avoid going over obstacles such as rough terrain, rocks, logs highly irregular ground, steps, ditches, railroad tracks. When obstructions must be crossed, do so with extreme care at an angle, if possible. Reduce speed, shift-down. Ease up to the break over point, pass the balance point slowly on the obstruction and ease down on the other side.

- Always remember to position the transmission drive control in neutral and engage the control lock to secure the machine. - The parking brake is automatically set, when the transmission safety lever is lowered.

- In steep down-hill operation, do not allow engine to overspeed. Select proper gear before starting down grade.

- NEVER LEAVE THE MACHINE UNATTENDED with the engine running.

SAFETY RULES

SAFETY RULES FOR SEALS

VITON SEALS (fluoroelastomer)

2) identify the type of material of the seals, if they are VITON, performing the test illustrated below, on the spare parts;

Seals, especially VITON O-Rings, (normally coloured red) are used in systems operating at high temperatures, since this materials resists the effects of heat. However, in the event this material is subject to heat exceeding 315 °C (in practice, only in case of fire or when using welding flames) fluoridic acid is generated. This acid is highly corrosive and could cause severe burns, if in contact with the skin. Every time it is necessary to intervene on components equipped with VITON rings, for which an exposure to excessive temperatures is suspected, the following procedures must be applied:

3) in case it is verified, or there is a reasonable doubt that the components are made of VITON, the contaminated area MUST be decontaminated before proceeding with further operations; 4) wear neoprene rubber or PVC gloves and protection goggles or face screen, and wash accurately the contaminated zone with a solution of hydraulic lime (found at building stores) and water, so that a milky liquid is obtained. Rinse carefully with steam or running water;

1) inspect visually, without touching them, all seals showing signs of damage due to high temperature. They look black and tacky;

5) dispose of the materials removed and the protective gloves in a safe manner, without burning them.

TABLES OF TECHNICAL DATA STEERING SYSTEM

The machine uses a differential steering system; this consists of a hydraulic pump, a hydraulic motor, two epicyclical control modules and steering gear train. The rear transmission has two power inputs. One from the bevel gear set for the speeds and forward & reverse, the other from the motor to steer.The steering system is actuated by two "finger top" potentiometric levers located on the left side of the operator's compartment. The levers send an electric signal to the microprocessor that controls the two electro proportional valves. These valves convert the electric signal into a hydraulic signal, to pilot the steering section of the main valve.This section controls the pump flow to the hydraulic motor that, through the steering gear train, actuates the two epicyclical modules and the right track chain. Open hydrostatic circuit includes: main pump The same of the equipment (see hydraulic system)

GENERAL INSTRUCTIONS INSTALLATION OF SEALS ON ROTATING SHAFTS Please follow these cautions: - prior to the installation, keep the seals soaking in the same oil they shall work with for half an hour;

- during the pressing, make sure that the seal is introduced perpendicular to the seat and once the installation is completed, that it contacts the bottom face; - to prevent that the sealing lip is damaged by the shaft, it is suggested that during the installation an appropriate seal be placed in between.

- clean accurately the shaft and make sure that its working surface is undamaged; - direct the sealing lip toward the fluid; in case of a hydro dynamic lip, the rifling must be oriented considering the movement direction of the shaft, moving the fluid toward the inside of the seal; - smear the sealing lip with a film of lubricant (oil is preferred over grease);

INSTALLATION OF O-RINGS Lubricate the seals prior to inserting them in the relevant seats that, during the installation phase, tend to twist thus altering the correct positioning, jeopardising the sealing function.

- insert the seal into the relevant seat pressing it or using a punch with a flat face; avoid absolutely to strike it with a hammer or a mallet;

RECOMMANDATIONS FOR THE DISASSEMBLY AND REASSEMBLY OF GROUPS The following information, of a general type, have the purpose of facilitating the disassembly and reassembly of groups.

D150

DISASSEMBLY It is always recommended for any intervention on the engine or other groups removed from the machine, use the appropriate supporting rigs.

Thus please read and heed them carefully when performing the work.

Always make available boxes and containers capable of holding small parts removed. Take particular care that machined surfaces of various parts are resting, after the removal, on wooden blocks or shelves.

CLEANING

When disassembling similar parts, such as valve tappets etc. are placed in appropriate containers, so that the same installation sequence is re-established.

After disconnecting the electrical system, clean accurately all the parts to be disassembled, preferably with a jet of steam. In many repair or service shops caustic compounds are used to eliminate traces of grease, dirt, paint and remains of seals etc. from the parts. These compounds are very useful and effective when properly used, but can cause serious damages to certain materials. Materials such as aluminium, rubber, fibres sintered bronze and alloying agents are sensitive to all highly concentrated caustic compounds. Some heat exchangers are built with aluminium fins. To clean them both internally and externally these parts the use of solvents not reacting with aluminium is recommended.

ASSEMBLY Clean accurately all components to assemble as described in the various paragraph of the manual. The use of special tools illustrated in the manual is recommended.

Note – For the applications of sealing compounds please comply with the instructions prescribed on the various commercial products.

Carefully read personal and machine SAFETY PRECAUTIONS (at the beginning of this manual)

The manufactured prescribes, unless differently specified, the following sealing compounds: VIT type C or RHODORSIL CAF 1, or LOCTITE 510. Whenever possible, press the bushes into a correct position, using a press. If the use of a hammer is required to install a bush, use an appropriate punch to prevent damaging the bushes. Lubricate ball bearings and bushes before installing them in the relevant pins. Lubricate the sealing lip of new seals. In particular, new seals must always be used for engine cylinder heads. Use fittings of dimensions and specifications as indicated referring to the part numbers listed in the Parts catalogue. When prescribed, use safety washers, split pins, locking wires etc. Comply with the prescribed tightening torques as indicated in the "tightening torque" section of this Manual, using an appropriate toque wrench. Self-locking nuts must be replaced at each installation to ensure constantly a good resistance to the loosening.

- Keep all inner threads clean. - Remove immediately the caps before connecting the pipes and plug all open ends. - Never use or re-use flanges or half-flanges deformed more than 0.6 mm (0.02 in) in the centre (see figure). - Make sure that the seat of O-Rings is not damaged.

Wrong

Correct

- Lubricate the O-Rings. - Make sure that the O-Rings are well seated. - Tighten regularly to prevent distortions or damages

GENERALITIES

- Tighten regularly to prevent distortions or damages to the O-Rings.

Wrong

- Install pipes and supporting straps letting the latter slightly loosen (tighten the strap after tightening the connections). - Ensure that the pipes can reach the opposite side to be connected without being forced.

Correct

- If a pipe is installed in a straight position, allow sufficient room to absorb contractions due to the pressure. D350R0410

- Pipes must not be twisted (see figure) nor touch one another nor touching other parts, especially moving parts. - Make sure that the dimensions of bands is correct in relation to the diameter of the pipe to be secured to prevent possible rubbing (see figure). - Do not install a band over a minimal curve to prevent that under pressure, the hose is stressed (see figure: the dotted part indicates the contraction that the pipe can be subject to under the effect of the pressure). - Make sure that bands are installed in the right position so that the hose is kept away from obstacles (see figure).

DIAGNOSTIC CHECKS GENERALITIES For a fat troubleshooting, please follow these rules:

a) Knowing the machine. It is impossible to perform any troubleshooting and to formulate a diagnosis without knowing well the machine. Thus it is recommended that the descriptions contained in the Repair Manual about the configuration and the operation of the different groups be read carefully.

e) Diagnosis Once the trouble is identified, make a list of possible causes with the help of the suggestions in the chapter relative to the group involved and identify the correct one by performing the appropriate tests, starting from the most probable causes and from the easiest tests.

b) Check with the operator. Many troubles are originated by an improper operation or insufficient maintenance. Check with the operator whether the machine experienced previously troubles similar to the ones in progress and whether any intervention was performed using appropriate tooling and genuine spare parts. Also, check the ambient working conditions of the machine and make sure that current maintenance is performed.

c) Operating the machine. The best way to check the conditions of a machine is to operate it under normal working conditions. In doing this check: - the correct operation of the monitoring instrumentation; - the performance of the machine; - possible odours or signs of overheating; - abnormal noises; identify their origin and the operating conditions when they occur.

d) Inspecting the machine. After the test of item c, stop the machine and have a visual inspection. Check whether the various groups show signs of leakage of fluids, loose fixtures, failures or deformations etc.

2.1 GENERAL DESCRIPTION 2.1.1 TRANSMISSION TORQUE CONVERTER HYDRAULIC DIAGRAM The transmission is of a "power-shift" type with three forward and three reverse speeds. The system is powered by a dual pump feeding the transmission and the torque converter (1). The pump sucks oil from the transmission housing through filter (6) and circulates it purifying further through filter (2). A valve (set at 2.5 bar) (36.25 psi) protects filter (2) against over pressures due to the clogging of the cartridge or excessively thick oil. The feeding pump of the hydraulic system steering clutches sucks the oil accumulated in the torque converter support housing, through a mesh filter (14) and returns it to the transmission housing. The oil delivered by feeding pump (1) after being purified by filter (2) reaches pressure relief valve (3) establishing and maintaining the pressure setting of the oil controlling the transmission clutches. Safety valve (16) protects the torque converter and the heat exchanger against accidental pressure in-

crements, normally due to cold and excessively thick oil, discharging the flow excess into the pump delivery line (1). The oil flowing out the torque converter, passes through the heat exchanger, the manifold and it is distributed to the lube and cooling ducts of the transmission clutches. The maximum lube pressure is limited by valve (15) set at 3 bar (43.5 psi). Modulating valves (9) make the engagement of the clutches progressive, regulating the pressure increment in the control circuits. A low engine lube oil pressure or an excessive lube oil temperature are indicated on the dashboard in the cab. Quick discharge valves on the 2nd and 3rd speed clutches, during the speed engagement phase, are in closed position, under the action of pressurised oil. When shifting from one speed to another, the relevant control cylinder is connected to the discharge and the pressure drop causes the centrifugal force to prevail over the action of the oil, moving the balls outwards, facilitating a quick discharge.
