A.
Set the park brake.
B.
Open the by-pass valve.
C.
Remove the oil filter.
D.
Remove the top plug on the right side
transmission (reinstall at 110-150 in-lbs)
E.
Remove the side plug on the left side
transmission (reinstall at 180-240 in-lbs)
F.
After all the oil is drained out, replace
the filter (use part # H-2567 when
ordering from Country Clipper).Wipe off
the filter base surface, apply a film of
new oil to the gasket of the new filter
and hand tighten ¾ to one full turn after
the filter gasket contacts the filter base
surface.
G.
Refill the transmission with the
recommended oil through the expansion
tank. When the oil level in the
transmission reached the top or side
plug port reinstall the plug and continue
filling until the “Full Cold” line is reached
on the expansion tank. Each
transmission will take approximately 2
quarts of oil.
NOTE: Due to the effect air has on efficiency in
hydrostatic drive, it is critical that it be
purged from the system.
These purge procedures should be
performed any time a hydrostatic
system has been opened for
maintenance or oil has been added to
the system.
IMPORTANT:
Failure to purge system properly may
cause one or all of these symptoms:
1)
noisy operation.
2)
Lack of power or
drive after short term operation.
3)
High
operation temperature and excessive
expansion of oil.
1. PURGING
PROCEDURE
Oil Hydrostatic Transmission
NOTE: Before starting procedure make sure the
transmission is at the proper oil level. If
it is not, fill to specifications.
The following procedures should be
performed with the vehicle drive wheels
off the ground then repeated under
normal operating conditions.
A.
With the transmission unlocked (see
page 10 for details) and engine running,
slowly move the directional control in
both forward and reverse directions 5 to
6 times. As air is purged from the unit,
the oil level will drop.
B.
With the transmission locked and the
engine running, slowly move the
directional control in both forward and
reverse directions (5 to 6 times). Check
the oil level, and add oil as required
after stopping engine.
C.
It may be necessary to repeat Steps A &
B until all air is completely purged from
the system. When the transaxle moves
forward and reverse at a normal speed
purging is complete.
