Transaxle Repair - Bench Work
General Information
If the tractor is still under warranty, a damaged transaxle would be replaced and not repaired. That being said,
dealers are encouraged to check warranted transaxles for a cause of failure. It only take a few minutes to open a
transaxle for inspection. If it prevents a claim from being denied, it is worthwhile.
Transaxles are typically replaced in customer pay situations. If a transaxle is not damaged too badly, it makes
sense to compare the cost of repair to the cost of a new transaxle. The repaired transaxle can be reinstalled, or sold
at a later date.
1. Assess the damage from the outside;
See Figure 5.58.
1a. If the tractor is within the warranty period, is
the damage consistent with a warrantable fail
-
ure?
1b. If the tractor is beyond the warranty period, is
the transaxle feasible to repair?
1c. Are the axles bent?
1d. Is the housing broken from the outside-in?
1e. Is the housing broken from the inside-out?
1f. Spin-test:
• Will the input shaft turn in neutral?
• Will it drive the wheels forward in forward gear?
Hold the brake rotor and check input-shaft back-lash. It should be 0.006”-0.014” (0.15-0.36mm).
• Will it drive the wheels backward in reverse gear?
Hold the brake rotor and check input-shaft back-lash. It should be 0.006”-0.014” (0.15-0.36mm).
1g. If it fails the spin test, are the brakes too tight?
2. If further investigation is required to determine the
cause of the failure or to asses the feasibility of
repair, disassemble the transmission using the fol-
lowing steps:
NOTE: steps #4 through #6 can be skipped if this is
a warranty-related autopsy.
3. Slide the shift-shaft pillow block off of the shift shaft.
See Figure 5.59.
4. Remove the detent screw using a 1/4” allen wrench.
