l
Wait for the oil and water to cool before working on the hydraulic circuits and on the engine.
l
During removal and assembly operations for some groups, it is necessary to support the engine; use saw horses, jacks or
blocks suitable for the weight to support and put it in a triangular position to prevent it from flipping over.
l
Use a hoist or a crane to lift heavy components. Make sure that metal cables, chains or fibre belts are not worn and that the
hooks are not damaged.
l
Always use lifting equipment which can easily support the weight of the units to remove and connect correctly.
l
When lifting or supporting a unit or part of the engine, work slowly to prevent dangerous swinging and damaging collisions
with other parts.
l
Never work on parts or units hanging on a hoist or crane.
l
If removing the screws from units which can fall, always leave two opposite screws for safety purposes; remove these screws
only after having hooked the unit to a lifting device or after having positioned support blocks.
l
If fuel or oil drips on the floor during removal or assembly operations, clean it as soon as possible to avoid operators slipping
and possible fires.
l
If electrical cables or wires are removed, make sure that they are reassembled with their original fastening, to prevent machine
vibration from damaging them.
l
Never insert your hands or fingers to check the alignment between two holes, use soft material pins.
l
When installing units or parts, always use the torques indicated in the general tables; the torques indicated in the paragraphs
regarding assembly, are specific torques whose values have been determined by testing and they must absolutely be com -
plied with.
l
If installing parts subject to strong vibrations or which turn at high speed, pay particular attention during the final test of the
installation.
0.2.3 - precautions to use during performance of the work
When disassembling or assembling a part, always follow the general precautions below.
precautions for disassembly
l
After disconnecting the pipes of the hydraulic system and fuel supply system, fit the caps to prevent impurities from entering.
l
Use a container with sufficient capacity to recover oil, coolant or fuel.
l
Before removing a machine part, check the alignment references which indicate the correct assembly position. Add additional
marks if necessary to avoid incorrect assembly.
l
When disassembling the connectors, always hold them tightly to prevent forcing on the electrical cables.
l
Mark the electrical cables and pipes if necessary to avoid mixing them up during assembly.
l
Check the number and height of the shims and put them in a safe place.
l
To lift the engine or parts of it, use equipment that is adequate for the component weight.
l
When using eye-bolts to remove engine parts, make sure they are not deformed; completely tighten them and then align the
direction of the eye with the lifting hook.
l
Before removing a part, accurately clean the surrounding area and, after removing the part, cover it to prevent dirt and dust
from getting on it.
precautions for assembly
l
Tighten nuts and screws with the specified torques.
l
Fit hoses and wiring being careful not to bend or twist them.
l
Replace gaskets, O-rings, split pins and safety stop rights with new parts; make sure the tines of the split pin are separated
and bent and thus so they cannot come out of their seats.
l
After fitting the snap rings, make sure they are well inserted in their seat.
l
When you need to lock threading with sealant, clean the part removing oil and grease, then apply drops of adhesive in order
to uniformly cover the threading.
l
To apply sealants, clean the involved surface, remove any residual oil and grease, make sure there are no dents or dirt, then
apply the sealant uniformly making sure it completely surrounds any holes.
l
Clean all the parts, remove dirt, oxidation, carbonaceous deposits, burrs and dents.
l
Apply a film of engine oil to all moving parts.
l
When fitting the electrical system connectors, remove oil, dust or water which can penetrate between the contacts and then
connect them tightly; when required force the connectors until the twin lock catch.
l
Lock the flanged couplings uniformly, tightening the screws in a crossed and alternating sequence.
