[212 JH] CRANKSHAFT WEAR
RING
When the service oil seal is to be replaced and
the crankshaft flange is worn, the crankshaft can
be salvaged by installing a crankshaft wear ring.
An oil seal with a larger inside diameter is used
with this wear ring.

Removal
A limited number of crankshafts were
manufactured with a repair sleeve installed on the
flange. The repair sleeve is usually not noticeable
and is finish ground to standard flange size. If the
repair sleeve is damaged or becomes loose, the
crankshaft must be replaced.
Special care must be taken not to damage the
crankshaft flange during wear-ring removal.
Refer to Figure 6-33.
1. The wear ring can be removed by carefully
applying heat, using a ball-peen hammer to
expand the diameter, or by using a chisel to
split the wear ring. Use extreme care not to
damage the crankshaft flange.
Place chisel face squarely on wear ring. Use
careful blows to cut wear ring only and not
damage crankshaft flange. The wear ring will
become loose enough to remove without cutting it
completely through. The goal is to carefully
remove the wear ring in this manner and not cut,
nick, or damage the crankshaft flange.
2. Thoroughly clean the flange area of the
crankshaft. Check for nicks or scratches and
repair any damaged areas with crocus cloth
as necessary.

Installation
Refer to Figure 6-34.
On some wear rings it may be difficult to
determine the direction of the arrow on the inside
diameter. In this case, ensure proper installation
by installing the wear ring with the chamfer on the
inside diameter toward the engine. The chamfer
on the outside diameter of the wear ring must
face away from the engine.
The crankshaft wear ring is shrink fit on the
crankshaft flange. Use wear ring installer J 38880
and universal driver handle J 8092 to install the
ring to the proper depth.
