7. If previously disassembled thoroughly clean all exposed surfaces on the
spacer (29E) and all exposed threads on the plunger bolt (29C) and the
steel plunger base (25). Threads MUST be free of old loc-tite and any other
material such as oil, grease, etc. This is necessary to ensure proper curing
of new loc-tite. Giant recommends cleaning the threads with acetone or
other suitable cleaner. Reassemble plunger assembly parts (29A, 29B, &
29E) using a new copper gasket (29D) and the cleaned plunger bolt (29C).
Slide the bolt through the center of the four (4) pieces so that the threaded
end is exposed. Apply several drops of loc-tite 243 (or equivalent)
adhesive to the threads. Thread into steel plunger base and tighten to 26
ft.-lbs. BE CERTAIN ALL PARTS ARE CENTERED WITH THE BOLT!
