3.
Before removing the tank caps (C), make sure the area
around the tank cap and fill neck of the tank is free of dust,
dirt, or other debris. Remove the tank cap.
4.
Add oil up to the full cold mark.
5.
Reinstall the tank caps.
6.
After adding oil to the tanks, it may be necessary to purge
air from the hydraulic system. If the unit is not driving
properly perform the
Purging the Air from the Hydraulic
System procedure.
Transmission Oil Filter Change
Change Interval: Every 400 Hours or Yearly (Initial hydraulic
oil and filter change after first 100 hours of operation)
Replacement Filter Number: 5101026X1
Note: Removing the oil filter from the transaxle will drain the oil
tank. Have a suitable container ready to catch any spilled oil.
The manufacturer recommends that this be a dealer-only service
item.
1.
Locate the transmission oil filters (A, Figure 24) underneath
the rear of the machine on the transmissions.
24
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 bumper of the machine to secure it.
2.
Open the transaxle’s bypass valves (see
Pushing the Rider
by Hand for the location and function of the bypass valves),
start the engine, release the parking brake, and slowly move
the zero-turn rider’s ground speed 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.
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 zero-turn
rider’s ground speed 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.
