Maintenance and replacement of
gearbox and drive axle oil
The oil product added to the torque converter -
gearbox assembly must be consistent with oil list
TE-ML 03 recommended by ZF, the oil level shall
be checked once a week by the following
methods:
1) Park the machine on level ground;
2) Place the gear box gear in the neutral posi-
tion;
3) Torque converter - gearbox oil is at 80-
95°C\176°F~203°F;
4) The engine is idling 800rpm);
5) Observe the oil level gauge of gearbox and
it shall be in the "HOT" zone;
After the torque converter and gearbox assembly
co-work for the first 100h, the oil shall be
replaced every 1000h or at least once a year. Oil
can be replaced by the methods as below:
1) Unscrew the drain plug on the torque con-
verter - gearbox assembly to drain the oil.
2) After the Oil sump tank of the gear box com-
pletely gets empty, wipe clean the mating
surface on drain plug and gearbox housing
that contacting with O ring of the oil drain
plug. After the O-ring of the oil drain plug is
replaced, reassemble and tighten it.
3) Add the oil in accordance with the oil list TE-
ML 03 as recommended by ZF;
4) Check the oil level by the method as speci-
fied for transmission.
The fine oil filter is also replaced every time the
oil change is done for the gear box. The oil filter
may be installed by the following method:
1) Apply a small amount of the gear box oil on
the oil seal of oil filter;
2) The oil filter is screwed in until the oil seal of
oil filter contacts the filter head, tighten it 1/3
to 1/2 turn by hand.
The oil product added in the drive axle must be
in accordance with the oil list of 85W-90 heavy-
load wheel gear oil (GL-5) recommended by
LiuGong. The oil level of LiuGong axle may be
checked by the following methods:
The waste oil shall be collected in a container
during oil drainage, in order to avoid environ-
mental contamination;
The oil shall be fully cooled before oil drain-
age, in order to avoid personal injury due to
hot oil splashing onto the body.
