5.11.1.3 - Draining the oil from the final drive units
Every 2000 hours
• Unscrew the drain plug (Ref. 1, Fig. 23).
• Refit the drain plug.
• Top up the level through the filler cap (Ref. 1, Fig. 24).
The oil level should be 55 mm below the filler cap.
5.11.2 - Auxiliary hydraulics
Check the oil level every day using the dipstick (Fig. 25).
NOTE: When using hydraulic implements taking a large
quantity of oil out of the transmission (hydraulic
motors, large capacity cylinders) top up oil to the max-
imum level. When you change transmission oil, you
MUST bleed the hydraulic and braking circuits. If nec-
essary, ask your nearest dealer for assistance.
5.11.2.1 - Draining the auxiliary hydraulics
Every 1200 hours
To carry out the draining, the oil must be hot and linkage
must be in lowered position with all rams retracted.
• Unscrew the drain plug (Ref. 1, Fig. 26).
• Fill the tank via the breather plug (Ref. 1, Fig. 28).
• If the hydraulic system is polluted, change the 300
micron steering suction strainer (2. Fig. 27) and the 300
micron LS pump suction strainer (1. Fig. 27).
NOTE: the tank must be disassembled for this latter
operation (see your dealer or agent).
