shaft.
12. Install the oil intake hose on the intake fitting located
on the front right of the transaxle and secure with a
hose clamp.
13. Purge the air from the transaxle. Refer to Section 2,
"Purging Air From Transaxle".
14. Check for proper neutral adjustment. Refer to
Section 2, "Neutral Adjustments".

the up position, turn the adjusting nut in until it just
contacts the brake rod spring without compressing it.

"cold full" line approximately 1/4" from the bottom of
the reservoir. Top off as needed using a good grade
of SAE 30 weight engine oil. Run the transmission for
a while to test and recheck the oil level.
