MAINTENANCE
PURGING TRANSAXLES
Due to the effects air has on efciency in hydrostatic
drive applications, it is critical that it be purged from
the system.
These purge procedures should be implemented any
time a hydrostatic system has been opened to fa-
cilitate maintenance or any additional uid has been
added to the system.
Purging may be required if the unit shows any of the
following symptoms:
- Noisy operation.
- Lack of power or drive after short term use.
- High operation temperature, excessive oil
expansion.
1. Check the transaxle uid, ll to proper level, if
required.
2. Raise the drive wheels off the ground. Support
unit with jackstands or other suitable means.
3. With the bypass valves open, and the engine
running, slowly move the control levers in both
forward and reverse directions 5 to 6 times. As
air is purged from the unit, the oil level will drop.
4. With the bypass valve closed, and the engine
running, slowly move the control levers in both
forward and reverse directions 5 to 6 times.
5. Stop engine. Check the transaxle uid level, add
uid as required.
6. It may be necessary to repeat steps 3-5 until all
the air is completely purged from the system.
When the transaxle moves forward and reverse
at normal speed, purging is complete.
