Service Manual Print No. 84568077A 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.

IV


SAFETY RULES - Be alert of people in the operating area of the machine.

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

- 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.

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

SAFETY RULES

SAFETY RULES FOR SEALS VITON SEALS (FLUOROELASTOMER)

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 (599 °F) (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:

black and tacky; 2) identify the type of material of the seals, if they are VITON, performing the test illustrated below, on the spare parts; 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; 5) dispose of the materials removed and the protective gloves in a safe manner, without burning them.

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

STEERING SYSTEM D350

23/35 M

10

The machine uses a differential steering system; this consists of a hydraulic pump, a hydraulic motor, controls, two planetary modules and a steering gear train. The rear transmission has two power inlets. One from the bevel gear for the speed and Forward reverse, the other from the motor, to turn. The steering system is actuated by two "finger tip" potentiometric levers, located on the left side of the operator's seat. The levers send an electric signal to the microprocessor controlling the two proportional solenoid valves; these valves convert the electric signal into a hydraulic one, piloting 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 planetary modules and the right track chain.

The steering system is controlled by two levers installed on the left side of the operator’s seat. When the lever is moved, a modular pressure is forwarded through the controller and the proportional solenoid valves to the steering control valve. The service brakes system is negatively controlled by the brake pedal or when pulling the two levers at the same time. The actuation of the pedal cuts with a modulation the backpressure of the brake piston so that the springs apply a braking load.

GENERAL INSTRUCTIONS INSTALLATION OF SEALS FOR ROTATING SHAFTS Osservate le seguenti avvertenze: - prior to installation, keep the seals half an hour dipped into the same oil they are going to seal; - clean accurately the shaft and make sure that its working surface is undamaged; - direct the sealing lip towards the fluid; in case of an hydro dynamic lip, the grooves must be oriented so that the rotating direction of the shaft, tend to return the oil inside the seal; - smear the sealing lip with a film of lubricant (oil is preferred to grease); - install the seal into its seat by pressing it or using a punch with a flat contact face; absolutely avoid hammering it; - when pressing the seal, make sure that it is entered perpendicularly to its seat and once the pressing is over, make sure, when requested, that is seated against the shoulder; - in order to avoid damaging the sealing seat with the shaft, it is recommended, during the installation of the two parts, to insert an appropriate seal. INSTALLATION OF O-RINGS Lubricate the seals before placing them into the relevant seats so as to avoid that, during the installation, they tend to roll, thus altering their correct positioning, being furled, causing prejudice to their sealing function. RECOMMENDATIONS FOR THE DISASSEMBLY AND REASSEMBLY OF GROUPS The following information, of a general nature, are intended to facilitate the disassembly and reassembly of groups. Consequently, read and heed them when performing this type of operations.

CLEANING After disconnecting the electrical system, clean accurately all the parts to be disassembled, preferably using steam. In many repair or service workshops, caustic compounds are used to eliminate all traces of grease, dirt, paint or remains of sealing materials etc. from the parts. These compounds are very useful and efficient when used correctly; however they can cause considerable damages to certain components. Materials such as aluminium, rubber, fibres, sintered bronze and alloying elements are particularly sensitive to all highly concentrated caustic compounds. Some heat exchangers are made with aluminium fins. To clean internally or outside these parts, the use of solvents not reacting with aluminium are recommended. DISASSEMBLY It is always recommended, for any intervention on engines or other assemblies removed form the machine, that appropriate stands are used. Make available baskets or containers sufficient to store all the smaller size parts disassembled. Take particular care of machined faces of the components, placing them, after the disassembly, on shelves or wooden blocks. When identical parts are disassembled, such as valves, tappets etc., place them in appropriate containers to ensure the same mating order when reassembling. ASSEMBLY Clean accurately all the components to be reassembled, as described by the various chapters of the Manual. The use of the proper special tools shown in the Manual is recommended. Note – When applying sealing adhesive compounds, comply with the instructions provided with commercial products.

The manufacturer prescribes, unless differently specified, the following adhesive compounds: RHODORSIL CAF 1, or LOCTITE 510. Whenever possible, press bushes into their correct position using a press. In the event it is necessary to use a hammer to install a bush, use an appropriate punch to avoid damaging the bush. Lubricate ball bearings prior to their installation. Lubricate the sealing lip of all seals, prior to their installation. Whenever possible, install new seals; in particular new gaskets must be used on engine cylinder heads. Use screws with the dimensions and grade indicated, referring to the part number of the Spare Parts Catalogue. When indicated, safety washers, split pins and locking wires etc. must be used. Comply with the prescribed tightening torques indicated in the "Tightening torques" section of this Manual, using an appropriate torque wrench. Self-locking nuts must be replaced at each disassembly, to ensure a constant good performance against loosening. HIGH PRESSURE PIPES, CONNECTIONS, HOSES AND PIPES

Wrong

Correct

This chapter provides correct recommendations and procedures to be followed during the disassembly of pipes and relevant connections.

D350R0407

- Keep all internal and external threads clean; - Remove the plugs just before connecting the pipes and plug at once all open connections. - Do not use or reuse semi flanges out of shape more than 0.6 mm (0.02 in) in the centre (see figure). - Make sure that the seats of O-rings are undamaged.

Wrong

Correct

- Lubricate all O-Rings. - Make sure that O-Rings are in place in the relevant seat. - Tighten regularly so as to avoid distortions or damages to O-Rings;

- Install pipes and support bands letting the latter slightly loosen (tighten the band only after tightening the connections). - Make sure that the hoses reach the corresponding part to be connected to without forcing their position. - In the event a hose is mounted straight, let enough space to absorb contractions caused by pressure. - Hoses must not be rolled (see figure) or touching one another or touching other parts, especially if moving. - Make sure that the dimension of the bands is appropriate for the outer diameter of the pipe to be tighten to avoid possible rubbings (see figure).

D350R0409

Wrong

- Do not install bands on small diameter curves, to avoid that, under pressure, forces are generated in the pipe (see figure: the dotted lines indicate the contraction that the hose could be subject to under the action of the pressure).

Correct

- Make sure that bands are installed in a correct position so that the hose is kept away from obstacles (see figure). D350R0410

TROUBLESHOOTING GENERALITIES

d) Inspection of the machine

For a fast troubleshooting, we recommend the compliance with the following rules:

After the test described in item c, stop the machine and perform a visual inspection. Check whether leakages of fluids, loosening of fixtures, breakages or various deformations etc. occurred.

a) Knowing the machine It is impossible to research the causes and formula te a diagnosis of troubles without having a good knowledge of the machine. Thus it is recommended that the descriptions regarding the arrangement and the operation of the various groups provided by the Repair Manuals are carefully read.

e) Diagnosis Once the trouble is identified. prepare a list of the possible causes with the help of the suggestions of the chapter for the group involved and identify the correct one, using practical tests, starting from the most probable causes and the easiest tests.

b) Inspection with the operator Many trouble originate from a bad use or insufficient maintenance. Check with the operator if the machine was previously subject to the current trouble and eventual interventions have been performed with appropriate equipment and genuine spare parts. Also, check the environmental working conditions of the machine and make sure that current maintenance is performed. c) Operating the machine The best way to ascertain the conditions of the machine is to test it under real working conditions. During such test, check: - the correct operation of the monitoring instrumentation; - the performance of the machine; - eventual odours or signs of overheating; - noises different from normal operation noises; identify their origin and the operating conditions during which they occur.
