Transaxle Oil and Filter Change
Change the transaxle oil after the initial
break-in
period
of
75-100 hours.
Thereafter, change oil
every 400 hours
of operation as follows:
1.
Thoroughly clean the exterior of the transmis-
sion housing before servicing. Using a 1/4 in.
hex wrench, remove the plug on the lower inside
of each transaxle allowing the oil to drain.
2.
Remove and replace the oil filters using a 3/8 in.
hex wrench. (Refer to
Transaxle Oil Drain
Plug, Filter, and Guard Location
illustration.)

3.
Reinstall drain plugs.
4.
Remove the oil reservoir hose attached to the
elbow on top of the transaxles and remove the
elbows to access the oil fill openings.
5.
Fill the transaxles with 20W-50 (API Service
Class SL or higher) oil through the opening
where the elbows were. Fill up to the opening.
6.
Before reinstalling the elbows, screw the locking
nut on the elbows down until they are snug (the
o-ring on the elbow will be to the bottom of the
o-ring groove).
7. Reinstall the elbows. When the elbow begins to
be snug, position the elbow as it was when
removed and tighten the locknut.
8.
Fill both reservoirs to 1/4-1/2 in. (6-13 mm) with
20W-50 (API Service Class SL or higher) oil.
9.
Start and drive the unit for 1- 2 minutes.
10. If the transaxles sound noisy or have poor steer-
ing response, recheck oil level in both
transaxles by removing the elbows (check oil
level at fill opening).
11. If oil needs to be added refer back to steps 4-10.
