14. Check the interior of the transaxle housings.
14a. If there is heavy gear-tooth damage on the
ring gear of bevel gears, there is likely to
be large debris in the grease. Dispose of
the grease if the transaxle is to be rebuilt.
14b. If there is heavy wear on any of the contact
surfaces, there is likely to be small parti-
cles of metal in the grease. Dispose of the
grease if the transaxle is to be rebuilt.
14c. If the grease is obviously contaminated
with water or other substances, dispose of
the grease if the transaxle is to be rebuilt.
14d. If the transaxle is being warranted, leave
the grease and debris in place, after the
root cause of the failure is identified.
14e. If the transaxle is repaired, the damage is
isolated, and the grease is not contami-
nated with anything, it is acceptable to re-
use the grease. See Figure 6.97.

out.
