Track Drive Oil - Replace
To drain the oil in the track drive, position the unit as in above
figure. The oil drain plug (3) must be positioned straight down
with the oil supply plug removed to be used as a vent (4). Set
a container under the draining plug. Draining the oil should
always be done when the oil is hot, this will aid in the draining
and help prevent sludge. When the drive is empty, replace
the drain plug (3). Fill the track drive with the recommended
gear oil in the oil supply port (4) until oil reaches and starts
to leak out of level plug (2). Ensure that all three plugs are
tightened. Use fluid as noted in the "Fluid Specifications
Section" of this manual.
Always pay attention to oil leaks and loose bolts, detect
and correct these problems as soon as possible to prevent
damage to the track or machine.
