2. Remove the three 1/4” filter guard screws (C) and the filter
guard (B).
3. Clean the area around the filter base and remove the filter.
4. Apply a film of new oil to the gasket of the new replacement
filter. After the oil has drained, thread the new filter onto the
filter base until the gasket makes contact, then tighten 3/4
of a turn more.
5. Reinstall the filter guard with the three 1/4” filter guard
screws.
6. Using a hex bit swivel socket or a modified allen wrench
remove the top port plug (D) from the transmissions.
7. Remove the transmission expansion tank cap and fill with
oil until oil appears at the bottom of the transmission’s top
port (approximately 2 qts (1,89 L).
8. Reinstall the top port plug and tighten to 15 ft lbs (20,38
Nm).
9. Continue to add oil to the transmission oil expansion tank
until the oil level reaches the “FULL COLD” mark. Reinstall
the transmission expansion tank cap.
10. Repeat this process for the other side of the machine.
11. Perform the
Purging the Air from the Hydraulic System
procedure.
Purging the Air from the Hydraulic System
Due to the effects air has on efficiency in hydraulic drive
systems, it is critical that it be purged from the system.
These purge procedures should be implemented any time a
hydraulic system has been opened to facilitate maintenance or
any additional oil has been added to the system.
The resulting symptoms of air in the hydraulic system may be:
• Noisy operation.
• Lack of power or drive after short term operation.
• High operation temperature and excessive expansion of
oil.
Before starting, make sure the transaxles/transmissions are at
the proper oil levels. If it is not, fill to the specifications outlined
in the
Check / Fill Transmission Oil Level procedure.
Purging Air from the Hydraulic System:
1. Chock the front wheels to prevent the machine from rolling.
Raise the rear of the machine so that the vehicle’s rear tires
do not contact the ground. Position jack stands under the
rear of the machine to secure it.
2. Open the transaxle’s bypass valves (see Pushing the Unit
by Hand for the location and function of the bypass valves),
start the engine, release the parking brake, and slowly move
the unit's control levers in both forward and reverse
directions (5 to 6 times), as air is purged from the unit, the
oil level will drop.
3. Depress the neutral return pedals to return the transmissions
to neutral, stop the engine, and engage the parking brake.
4. Close the transaxle’s bypass valves, start the engine,
release the parking brake, and slowly move the unit's control
levers in both forward and reverse directions (5 to 6 times),
as air is purged from the unit, the oil level will drop.
5. Stop the engine. Remove the jack stands from underneath
the machine.
6. Repeat the process detailed above but with the unit's drive
wheels on the ground. The procedure should be performed
in an area free of any objects or bystanders.
It may be necessary to repeat the process detailed above until
all the air is completely purged from the system. When the
transaxles/transmissions operate at normal noise levels and
move smoothly forward and reverse at normal speeds, then the
transaxles/transmissions are considered purged.
Checking Tire Pressures
Tire pressure should be checked periodically, and maintained
at the levels shown in the Specifications chart. Note that these
pressures may differ slightly from the "Max Inflation" stamped
on the side-wall of the tires. The pressures shown provide proper
traction and extend tire life.
Lubrication
Lubricate the unit at the locations shown in Figures 32, 33, 34,
and 35 as well as the following lubrication points:
Grease
front caster wheel axles & yokes
deck lift pivot blocks
