4.
Using a torch, apply heat to the setscrews on the bottom
of actuator.
5.
Remove the two (2) setscrews (4) from bottom of the
actuator (1). Discard setscrew.
6.
Place two (2) 3/8"x16 NC bolts in threaded holes in bot-
tom of the actuator. Using a suitable bar, unscrew the
end cap (5). Remove the end cap from actuator (1).
7.
Remove the shaft (2) from piston sleeve (3) and the actu-
ator housing (1).
8.
Remove piston sleeve (3) from housing (1).
9.
Remove all seals and bearings from grooves. Discard
seals.
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 manu-
factured 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.
3.
Check the ring gear for wear and weld damage to the
pins.
4.
Inspect the cylinder bore for wear and scratches.
