c. Bearings. See TM 9-214.
d. Studs. Replace all bent and stretched studs. Repair minor thread damage with a thread restorer file.
Replace studs having stripped or damaged threads as outlined below:
(1) Remove, using a stud remover. Back studs out slowly to avoid heat buildup and seizure which can
cause stud to break off.
(2) If studs break off too short to use a stud remover, use extractor to remove.
(3) Replacement studs have a special coating and must have a small amount of antiseize compound
(appendix B, item
on threads before stud
is installed. Install replacement stud slowly
heat buildup and snapping off.
(1) Remove gears using pullers,
(2) Use the same methods described
in paragraph 2-15.b (2) for castings
to remove minor nicks, burrs,
or scratches on gear teeth.
(3) If keyways are worn or enlarged, replace gear.
f. Bushings and Bushing Type Bearings. When bushings and bushing type bearings seize
to a shaft
and spin in the bore, the associated part must also be inspected and replaced, as required.
g. Oil Seals.
(1) Remove oil seals, being careful not to damage casting or adapter bore.
(2) Always install new seal in bore using proper seal replacing tool.
h. Locking Threads. When using thread sealing compound:
(1) Apply a liberal amount to both male and female threads on through-hole assemblies.
(2) Apply a liberal amount into the bottom of a blind hole (non-through hole assemblies). Installing the
fastener pneumatically forces the adhesive onto the threads.
(3) Assemble parts shortly after applying thread sealing compound to allow adequate coating of threads.
a. Cleanliness is essential in all component assembly operations. Dirt and dust, even in minute quantities,
are abrasive. Parts must be cleaned as specified, and kept clean. Wrap or cover parts and components when
assembly procedures are not immediately completed.
b. Coat all bearings and contact surfaces
with operating oil (differential oil for differential parts,
transmission oil for transmission parts, etc.) to ensure lubrication of parts during initial operation after
