WARNING:
Avoid scalding due to hot transmission fluid and parts and avoid fire
caused by contact to the fire source.
1. Remove the drain plug and place it into a proper container. Handle the fluid
according to environmental protection requirements.
2. Clean the drain plug 2 with magnet.
3. Replace seal rings of drain plug and filler.
4. Tighten the drain plugs 1 and 2 to the specified torque (60 Nm).
Add oil
1. Add the transmission fluid through the filler.
2. It indicates that the transmission is filled with fluid when the level reaches to the
lower end of the filler, in this case, continuous adding may cause overflow of fluid
out from the filler.
3. Tighten the filler to the specified torque (60 Nm).
CAUTION:
Check the transmission for fluid leakage when checking the level.
Check and replace retarder oil (ZF)
Check the oil level
CAUTION:
Insufficient oil in the transmission will lead to transmission damage and
accident risk
WARNING:
Insufficient oil in the transmission will lead to the retarder failure, brake.
torque weakening or failure. Please use the auxiliary brake carefully
when continuing to drive, or maintain the transmission.
Operation method:
1. When checking the oil level, the retarder must be closed before stopping, which
can ensure the correct oil quantity in the transmission
2. In order to prevent incorrect inspection, the oil level of the transmission with
retarder must be checked according to the following methods:
1). Horizontal positioning of vehicles
2). engine flameout
3). the transmission oil temperature drop to below 40ºC
3. Check the transmission oil level regularly
4. Confirm whether there is oil leakage in the following parts when checking the oil
level
1). transmission
2). retarder
3). Oil/water heat exchanger
4). Relevant cooling piping
