SLEEVE HANDLING PRECAUTIONS
Use the following precautions for handling seal and wear
sleeve:
Seal (A) and wear sleeve (B) 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 immediately
after removal from plastic bag to avoid possible dirt
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 I.D. 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
