DISASSEMBLY:
Remove locknut, setscrew and follower.
ASSEMBLY:
Clean the follower and stud hole in the roller gear hub and inspect for elongation, which could cause
backlash by failing to support the stud at the top.
Apply a light coat of assembly grease to a new cam follower and install it firmly against seat; loosen
and retighten.
Install setscrew, tighten sufficiently to mark follower stud with setscrew point and remove setscrew.
Remove cam follower and drill a setscrew seat at the marked position deeply enough to make seat
diameter equal to setscrew diameter.
Clean cam follower, coat with grease and install firmly against seat; check that the drilled seat lines up
with the setscrew hole. Assemble setscrew and locknut and tighten firmly.
