not removed with rotor set and wear plate. Inspect drive

tible lash (play) should be noted between mating spline
parts. Remove and discard seal ring (4) from housing
(18).

(12). Inspect for wear, brinelling, corrosion and a full
complement of retained rollers.

Check exposed portion of coupling shaft (12) to be sure
you have removed all signs of rust and corrosion which
might prevent its withdrawal through the seal and bear-
ing. Crocus cloth or fine emery paper may be used.

Remove coupling shaft (12), by pushing on the output
end of shaft. Inspect coupling shaft bearing and seal sur-
faces for spalling, nicks, grooves, severe wear or corro-
sion and discoloration. Inspect for damaged or worn
internal and external splines or keyway. Replace cou-
pling shaft if any of these conditions exist.
NOTE:
Minor shaft wear in seal area is permissible. If wear
exceeds 0.020 inches (0.51 mm) diametrically, replace cou-
pling shaft.
NOTE:
A slight “polish” is permissible in the shaft bearing areas.
Anything more would require coupling shaft replacement.
