8. FOLLOWER REMOVAL
A. Apply heat to setscrews (26) and re-
move the setscrews 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 self
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 the capscrew into the
follower. Tightening the capscrew will
remove the follower.
C. Check the follower holes for roundness.
These holes may be elongated due to
overloads and jams.
