4.11 CHECKING THE TRANSMISSION
FLUID (HYDRO)
The transaxle is filled and tested at the factory and
should not require fluid when the unit is put into
service. Inspect the transaxle for leaks or damage to
the housing. If leakage is observed, do not operate
until the leakage is repaired.
Check the oil level and fill to the correct level if needed.
The oil should be between 1.25 and 1.60" from the top
of the housing in the 310-0750 axle. It may be checked
by removing the expansion hose. Typically, an API
classification CG/CD engine oil is used with a viscosity
range equivalent to 20W50.
4.12 PRIMING THE TRANSMISSION
(HYDRO)
The following is suggested for the priming of new or
repaired transaxles to assure proper operating
performance.
1. Locate the unit on a flat level surface to limit the
chance of the unit rolling while performing the
following procedures.
2. Actuate the bypass
(freewheel control).
3. Start engine and run at low idle.
4. Stroke the travel control pedal
forward for five
seconds and then reverse for five seconds. Do this
three times in each direction.
5. Return the travel control to neutral.
6. Disengage the bypass and drive the unit forward
and then reverse. Do this three times each way for
a distance of approximately five feet.
7. Some units may require repeating the previous six
steps to achieve proper operating performance.
4.13 CHECKING THE PTO CLUTCH
Measure Clutch Coil Resistance:
1. Turn engine and power take off (PTO) switch off.
2. Disconnect clutch wire connections.
3. Set meter to check ohms.
4. Connect meter leads in clutch connector.
