Transmission Maintenance
Oil Grade:
The permitted oil grade for the power-shift transmission is oils in the ZF list of
recommended lubricants T E- ML03.
This list of lubricants will be updated periodically and a copy can be requested from the
McConnel Service Department.
Factory fill of oil in the transmission is: - TOTAL RUBIA 10W
Oil Level Check:
IMPORTANT It is imperative that the correct procedure is
followed:
Transmission in neutral
Oil at working temperature 80-90
o
C
Engine at low idle
Handbrake on
Read following instruction thoroughly
The transmission oil check should be carried out with regard to the safety
directions and rules for accident prevention, the respective national regulations
have to be absolutely respected.
For example: the vehicle has to be secured against rolling with blocks to the
wheels.
The oil level check must be carried out as follows:
1. Oil level check (weekly).
2. The vehicle must be parked on level ground.
3. Transmission to be in the neutral position “N”
4. In a cold start situation, the engine must be running for about 2-3 minutes at low
engine idle speed. and the mark on the oil dipstick must be above the cold start
mark “COLD MIN” (see figure 4.2 B2)
5. At transmission operating temperature of about 80-90 degree Celsius.
6. At an engine low idling speed
7. Loosen oil dipstick by counter clock rotation, remove and clean it.
8. Insert oil dipstick slowly into the oil level tube until contact is obtained, and pull it out
again.
9. On the oil dipstick, the oil level must be in the area marked “ HOT “ (see figure 4.2
B2)
10. Insert the oil dipstick again, and tighten by clockwise rotation
If the oil level has dropped in the operating temperature condition below the HOT zone, it
is absolutely necessary to replenish with oil according to the recommend list of lubricants
TE-ML-03.
An oil level above the “HOT” mark will lead too a high oil operating temperature within the
transmission.
