remove drive link
Remove drive link (8) and inspect
it for cracks and for chipped or
damaged splines. No perceptible
lash (play) should be noted
between mating spline parts.
Replace, if necessary SEE FIGURE
remove & discard
Remove seal ring (5) from housing
(15) seal ring groove and discard
seal ring. SEE FIGURE 12.
remove & inspect
Remove commutator (9) which is
a close slip fit into housing (15),
by inserting two fingers into its
center cavity and lifting. SEE
FIGURE 13. The commutator drive
pin (10) will probably be in the
commutator when the
commutator is removed. Inspect
the commutator for nicks, burrs,
or brinelling on the outside
diameter surface. Inspect for
broken edges on the commutation
slots. Inspect the exposed area of
the drive pin slot for extreme
wear or damage. Only the
commutator drive pin can be
serviced separately. A worn or
damaged commutator will require
a new matched housing and
commutator service assembly set.
Remove commutator drive pin
(10) only if it must be replaced. If
the pin does not readily pull out of
the commutator, clamp the
exposed portion of the drive pin in
a vise and twist the commutator
from the drive pin by hand only.
