Transmission Purging
Purge procedures must be implemented if
the hydrostatic system has been opened for
maintenance or when more oil has been added to
the system.
Due to the effects air has on efficiency in
hydrostatic drive applications, it is critical to purge
the system. Follow the instructions on the next
page.
Resulting symptoms in hydrostatic systems may
be:
• Noisy operation.
• Lack of power or drive after short term
operation.
• High operation temperature and excessive
expansion of oil.
•
Shortened component life.
Before starting, make sure the oil tank is at the
proper oil level. If not, fill to the specifications
outlined above.
Perform the procedure first with the vehicle drive
wheels off the ground, then repeated under
normal operating conditions.
See
Moving Machine By Hand
in the
Operation
section for bypass linkage adjustments.
1.
Disengage the brake if activated.
2.
With the bypass linkage open and the
engine running at fast idle, slowly move the
directional control in both forward and reverse
directions (5 or 6 times). As air is purged from
the unit, the oil level will drop.
3.
With the bypass linkage closed 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 the engine.
4.
It may be necessary to repeat Steps 2 and 3
until all the air is completely purged from the
system. When the hydraulic drive operates
at normal noise levels and moves smoothly
forward and reverse at normal speeds, the
hydraulic drive is considered purged.
5. After the vehicle has been used two times, the
oil level must be checked while the oil is cold
and adjusted accordingly.
