Inspection
1.
Clean all parts thoroughly.
2.
Closely inspect all parts for excessive wear, cracks
and chips. Replace parts as necessary.
NOTE: A small amount of wear in the spline teeth will have
little effect on the actuator strength. New spline sets
are manufactured with a backlash of about 0.005 in.
per mating set. After long service, a backlash of
about 0.015 per set may still be acceptable in most
cases, depending on the required accuracy of the
application.

Check the ring gear for wear and weld damage to
the pins.
