NOTE: Customers and unfamiliar technicians may
attempt to add or check the fluid level at the
vent cap on the plastic over-flow reservoir.
See Figure 6.3.
6. After a thorough cleaning, to prevent contamination
of the fluid, the fill plug can be removed using a 1/4”
allen wrench.
See Figure 6.4.
7. Between 5 deg. - 100 deg. f (10 deg. - 38 deg. c),
the fluid level should be 1” - 1.25” (2.54cm -3.18cm)
from the top of the housing. Total capacity is 0.600 -
0.632 gal. (2271ml - 2391ml) of 20W-50 motor oil
having an API classification of SH/CD.
NOTE: The transaxle must be removed and
inverted to drain the fluid out.
NOTE: After a fluid change, purge the system and
top-up the fluid to the correct level.
Purging the system
1. With the engine at idle speed, and the by-pass valve open, slowly cycle the control lever from full forward to
full reverse positions 5 or 6 times.
2. Check fluid level, close the by-pass valve, and repeat the previous step. When the transaxle operates nor-
mally, without excessive noise, the purge process is complete; all the air is out of the system.
NOTE: Air in the system will cause a “growling” noise, and sluggish performance.
NOTE: In normal service, fluid replacement should not be necessary, but in the event of fluid contamination or
degradation, it can be done.
