5. INSPECTION OF CAM FOLLOWERS.
Inspect followers for damage or radial looseness. It
should not exceed .001 inch. Do not confuse radial
looseness with axial endplay. Endplay will be from
.03 to .06 as a normal condition. If it exceeds .06 it
may require replacement.
NOTE: Generally, followers are replaced as added
insurance against eventual failure.

6. FOLLOWER REMOVAL.
A. Remove the setscrews. Apply heat to the
setscrews holding the follower studs and
remove while still warm.
B. Threaded holes have been provided in the
ends of the follower for ease of removal.
Use a slide hammer or a simple self made
pull tool. The slide made pull tool consists
of a short piece of round tubing large
enough to clear the follower diameter and a
small flat bar with a clearance hole large
enough to insert a capscrew of equal thread
size as the follower pull hole. Slip the tube
over the follower, place the bar over the tube
and thread a capscrew into the follower
tightening the capscrew will remove the
follower.
