Transaxle Inspection - Toro Workman GTX Service Manual

Transaxle Inspection

1. Thoroughly clean and dry all internal transaxle parts.
2. Use emery cloth to remove nicks and burrs from all
transaxle components.
3. Inspect all gear teeth for roughness, material trans-
fer or other damage. Cracked, broken, missing or
chipped gear teeth are not acceptable. Replace gears
if worn or damaged.
4. Inspect splines on input and center shafts. If
cracked, broken, chipped or missing splines are found
on either shaft, replace shaft.
5. Inspect I.D. of all gears for excessive wear or scor-
ing. Gears should fit snugly on shafts.
6. Inspect all shaft bearing surfaces for worn or dam-
aged areas.
7. Inspect oil seal surfaces of shafts for wear or damage
and replace shafts if necessary.
8. Inspect shift shaft and pin clutch (Fig. 28):
A. The shift shaft should move freely in the groove of
the pin clutch.
B. The engagement arm of the shift shaft should not
have excessive scoring at surfaces that contact the
pin clutch groove.
C. The shift pins on the pin clutch should not be worn
or damaged.
9. Inspect differential assembly components (Fig. 29):
A. Inspect differential case for wear in side gears
and pinion shaft mating area. Replace the case if ma-
chined surfaces are scored or if the pinion shaft fits
loosely in the bore.
B. Replace pinion shaft if cracked or bent.
