ROLLER PIN DISASSEMBLY
New roller retaining bolts have a dry locking agent
applied to the threads. Before attempting to remove
the roller pins, heat the threaded area lightly with a
propane torch. Wear heat resistant gloves during
this procedure. Use a high quality hexagonal
wrench in good condition to avoid screw damage. A
small amount of valve grinding compound can be
applied to the tip of the hex wrench to ensure a tight
fit. Always use new bolts if they are removed for
inspection. Apply Loctitet 680 retaining compound
sparingly to the tapered head
portion of the roller
retaining screws. Do not allow locking agent to
contact the inside of the rollers. Do not lubricate the
rollerorrollerpin.
