Changing Hydraulic Oil and Filter
NOTE: Change the hydraulic oil filter and
hydraulic oil every 400 hours. Use Mobil 1
Extended Performance 15W50 Synthetic Oil
or equivalent for best component life
(p/n 00057100).
NOTE: When changing the oil, only about 1.4
liters will drain. The rest of the oil will remain
in the pumps and motors.
1. Clean around dipstick cap and dipstick.
Remove dipstick.
2. Place container under oil filter to catch
oil.
3. Remove oil filter.
4. Allow tank to drain.
5. Lubricate rubber gasket on new oil filter
with clean hydraulic oil.
6. Spin new oil filter onto filter housing until
it makes contact. Tighten oil filter
another 1/2 turn.
7. Add new oil to the oil tank. It will take
about 1.4 liters. Use Mobil 1 Extended
Performance 15W50 Synthetic Oil or
equivalent for best pump and wheel
motor life.
8. Check hydraulic oil level.
9. Properly dispose of waste oil.

Check coolant level when engine is cold.
Check coolant level at overflow reservoir.
1. Place unit in the service position (see
SERVICE POSITION on page 23).
2. Check coolant reservoir. Coolant should
be between the low and full marks with
engine cold.
3. If coolant is below the low mark, remove
cap, and add coolant to the full mark.
Refer to Engine Manual for the correct
type of coolant.
Changing Coolant
Refer to Engine Manual for the correct
procedure on when and how to change the

CLUTCH ADJUSTMENT
(Figure 25)
If clutch fails to engage or disengage properly
or begins to make abnormal noise, check the
air gap adjustment at the three inspection
slots.
To check:
1. Stop engine, remove key and wait for all
hot parts to cool.
2. Measure the air gap between the
armature and the rotor.
Minimum: A .016" feeler gauge should
slide between armature and rotor with
slight contact.
Maximum: A .020" feeler gauge should
slide between armature and rotor with
slight contact.
3. Repeat for each inspection slot.
To adjust:
1. If necessary, loosen gap adjustment
nuts until a .016" feeler gauge fits
between armature and rotor.
2. Slide a .020" feeler gauge between
armature and rotor.
3. Tighten gap adjustment nut until there is
slight contact on feeler gauge.
4. Repeat steps 1 – 3 at each inspection
slot.
NOTE: Adjust air gap as evenly as possible.
5. Start unit, engage and disengage PTO.
6. Shut off unit.
7. Recheck air gap and adjust if needed.
