SLEEVE HANDLING PRECAUTIONS
Use the following precautions for handling seal and wear
sleeve assembly (A):
Seal and wear sleeve are assembled. DO NOT
SEPARATE. If parts become separated, discard and
replace with a new assembly. Attempts to reassemble
will cause the wear sleeve to damage the seal allowing
engine oil to leak past seal.
Always install seal and wear sleeve assembly
A--Wear Sleeve
immediately after removal from plastic bag to avoid
possible dirt contamination.
No lubrication of any kind is to contact seal when
installing. Use of a lubricant may result in premature
seal failure.
Install oil seal/wear sleeve assembly with the open side
of seal and wear sleeve ID chamfer toward the engine.
If seal is reversed, engine oil may be lost because
grooves in oil seal lip would be incorrect with respect to
direction of crankshaft rotation.
