Check / Fill Transmission Oil

Oil Type:

20W-50 conventional detergent motor oil.

1. Check the oil level when the unit is cold. Locate the

transmission oil reservoirs (A, Figure 24) located on the
seat support plate. The oil should be up to the “FULL
COLD” mark (B). If the oil is below this level, proceed
to step 2.

2. Before removing the reservoir caps, make sure the area

around the reservoir cap and fill neck of the reservoir is
free of dust, dirt, or other debris. Remove the reservoir
cap.

3. Add oil up to the “FULL COLD” mark (B).

4. Reinstall the reservoir caps.

Transmission Oil Filter Change

Change Interval:

Every 200 Hours

Replacement Filter Number:

5101026X1

1. Locate the transmission oil filters (A, Figure

25) underneath the rear of the machine on the
transmissions.

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 from the transmissions.

7. Remove the transmission reservoir cap and fill with oil

until oil appears at the bottom of the transmission’s top
port (approximately 2 qts (1,89L).

8. Reinstall the top port plug and tighten to 15 ft lbs (20,38

Nm).

9. Continue to add oil to the transmission oil reservoirs

until the oil level reaches the “FULL COLD” mark.
Reinstall the oil reservoir cap.

10. Repeat this process for the other side of the machine.

11. Run the unit for several minutes and check the

transmission oil level.

IMPORTANT NOTE: Use caution after changing the filter; air
in the hydraulic system may affect the responsiveness of the
ground speed control levers. Repeat step 11 until the air is
out of the system.
