1. Apply a thin coat of the specified oil on the surface of
the rubber seal of each filter.
2. Turn the filter clockwise until rubber seal contacts the
filter adapter then tighten the filter an additional 3/4 to
1 full turn. Repeat for the other filter
3. Install the filter guards over each filter as previously
removed. Use the three screws to secure the filter
guards.
4. Verify the vent plugs are removed before adding the
oil (
Figure 44 ).
5. Slowly pour the specified oil through expansion
reservoir until oil comes out of
one of the vent plug
holes. Stop and install that vent plug. Torque the plug
to 20.3 N-m (180 in-lb).
6. Continue to add oil through the expansion reservoir
until oil comes out of the remaining vent plug hole on
the second transmission. Stop and install that vent
plug. Torque the plug to 20.3 N-m (180 in-lb).
7. Continue to add oil through the expansion reservoir
until it reaches the Full Cold line on the expansion
reservoir.
8. Proceed to the Bleeding the Hydraulic System section.
Important:
Failure to perform the Bleeding
the Hydraulic System procedure after changing
hydraulic filters and oil can result in irreparable
damage to the transaxle drive system.
Bleeding the Hydraulic System
1. Enter the operator's position. Start engine and
move throttle control ahead to 1/2 throttle position.
Disengage parking brake.
A. Move the bypass levers into the pushing the
machine position; refer to
Pushing the Machine
by Hand (page 21) . With the bypass valves open
and the engine running, slowly move the motion
control pedal in both forward and reverse (5 or
6 times).
B. Move the bypass levers into the operating
the machine position. With the bypass valve
closed and the engine running, slowly move the
traction-control pedal in both forward and reverse
directions (5 to 6 times).
C. Stop the engine and check the oil level in the
expansion reservoir. Add the specified oil as until
it reaches the Full Cold line on the expansion
reservoir.
2. Repeat step 1 until all the air is completely purged from
the system.
When the transaxle operates at normal noise levels and
moves smoothly forward and reverse at normal speeds,
then the transaxle is considered purged.
3. Check the oil level in the expansion reservoir one last
time. Add the specified oil as until it reaches the Full
Cold line on the expansion reservoir if necessary.
