Removing Rod Piston Pin Bushing
A—JDE98-8 Cup
B—JDE98-10 Bushing Remover/Installer
C—STD36104 Forcing Screw
IMPORTANT: Do not use pneumatic tools to remove
or install piston pin bushing.
Use care to properly align the JDE98-10
Bushing Remover/Installer (B) with
bushing so that the connecting rod is
not damaged.
1. Remove the used bushing with JDE98-8 Cup (A),
JDE98-10 Bushing Remover/Installer, and STD36104
Forcing Screw (C) from the JDE98A Connecting Rod
Bushing Service Set.
2. Clean rod bushing bore using a medium grit emery
cloth, as burrs will distort bushing. Install bushing on
side opposite rod burr.
3. If necessary, file a slight chamfer around bushing bore
to remove any sharp edges. Chamfer will also aid in
bushing installation.
4. Measure rod bushing bore in three or more places
approximately 45° apart.
