How to renew the lubricating oil of the ZF 45 A reverse gearbox
Note: When the lubricating oil of the reverse gearbox is renewed, the filter element should also be renewed.
1. Turn the filler cap ( W1) counter-clockwise with a 6 mm Allen Key (W2) and remove the cap together with
the filter that is fitted to the cap.
2. As there is no drain plug, the lubricating oil must be removed with a pump (X1). Connect a hose (X2)
to the pump. Push the hose into the suction tube (X3) and down to the bottom of the housing. Operate the
pump to remove the lubricating oil; approximately 2,0 litres (3.3 pints) 2.1 US quarts.
3. The outside diameter of the hose must not be more than 16,0 mm (0.625 in).
4. Add 2,0 litres (3.3 pints) 2.1 US quarts of ATF transmission fluid, see Section 9.
5. Pull the filter element (X4) off the filler cap. Fit the new ‘O’ rings (X2) and (X3) and push a new filter
element onto the filler cap.
6. Fit the filter and filler cap assembly and turn the Allen Key clockwise to fasten the filler cap.
7. Turn the handle of the dipstick (Y1) counter-clockwise to release the dipstick. Remove the dipstick.
Clean the dipstick and check the level of the lubricating oil. The level should be between the minimum
and the maximum marks (Y2). Add more lubricating oil if necessary. Insert the dipstick and turn the handle
clockwise to fasten it.
8. With the gear lever in the neutral position, run the engine at idle speed for a few minutes. This will
ensure that the lubricating oil has circulated around the oil cooler and its pipes. Stop the engine and check
the oil level again. Add more oil, if necessary. Insert and fasten the dipstick.
Caution: Some oil could flow back from the oil filter after the engine is stopped. This could cause the oil level
to be over the maximum mark on the dipstick. If this occurs do not remove the excess oil.
Note: In service the level of the oil can be checked with the oil hot or cold. Always check the oil level before
the transmission is used.
