Figure 4-18
3. Place an oil drain pan beneath the oil filter and remove
the oil filter from the transaxle.
4. After the oil has been drained, wipe the filter base
surface off and apply a film of new oil to the gasket of
the new replacement filter.
5. Install the new filter by hand, turn 3/4 to one full turn
after the filter gasket contacts the filter base surface.
6. Re-install the filter guard with three 1/4” screws.
Torque the screws to 65 in-lbs each. Figure 4-18
7. Repeat steps 2–6 for the opposite side transaxle.
8. Drain oil filters of all free flowing oil prior to disposal.
Place used oil in appropriate containers.

transaxles prior to filling with oil. This will allow the
transaxles to vent during oil fill. Figure 4-19

of each transaxles top port (approximately 2 qts. per
transaxle). Install the top port plug into each transaxle.
Torque plugs to 180 in-lbs. Clean up any oil that leaked
from the ports. Figure 4-19
