MAINTENANCE
TRANSAXLE & HYDRAULIC OIL
Do not perform engine maintenance without the en-
gine off and spark plug wires disconnected.
- Check cold.
- Add 20w50 oil if necessary to the indicated level.
- Do not overfill. When the oil warms up it ex
-
pands. If overfilled cold, the oil may overflow at
operating temperature.
Change the transaxle oil after the first 75-100
hours, then every 500 hours or yearly.
It is essential that the exterior of the transaxle be free
of debris, prior to fluid maintenance.
1. Raise the machine on the built in jack stands.
See jackstands section pg. 19. Put an oil drain
pan under the hydraulic oil filter located under the
center of the machine. Remove the filter
A
. This
will drain the oil from the reservoir. Remove the
hose from the filter to each transaxle. Remove
the filter adaptor
C
from each transaxle to drain
the transaxles. With another drain pan, drain the
remaining oil from the reservoir through the drain
D
on the lower left side of the reservoir. Dispose
of the used oil and filter properly.
2. Apply pipe compound to the reservoir drain plug
and reinstall in the reservoir. Check the O-ring
seal on the filter adaptor. Replace the O-ring if
there are any nicks or cuts. Wipe the mounting
surface on each transaxle. Reinstall the filter
adaptors to the transaxles. Tighten until the
adaptor body contacts the transaxle mounting
surface. Wipe the filter head mounting surface.
Oil the gasket of a new hydraulic oil filter and
install on the filter head. Tighten 3/4 to 1 turn
past the point where the gasket contacts the filter
head.
3. Fill the reservoir with 20w50 (15w50 is accept-
able) motor oil to the top. (Approximately 4 qts.).
4. Have more oil ready. Start the machine and
watch the oil level in the sight tube on the
reservoir. Add oil as the level drops below the
"FULL COLD" mark. Run the machine until the
oil level stabilizes.
5. Purge the transaxles, following the purging pro-
cedures.
See Purging Transaxles Page 24
