Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The seal and the wear sleeve must be replaced at the same time. Once the seal and the wear sleeve are separated, these components cannot be used again. Refer to Special Instruction, SMHS8508, "Special Handling Information and Installation Instructions for Crankshaft Seal Groups That Have Hydrodynamic Grooves In the Sealing Lip" before the seal is serviced.Note: Do not use any type of lubricant during the installation of the crankshaft seal and the wear sleeve.
The front and rear seals and wear sleeves have different spiral grooves in the seal. Because of this type of design, the front seal group for an engine is different from the rear seal group. If a seal group is installed on the wrong end of the engine, oil can actually be taken out of the engine instead of moving oil back into the engine.

Crankshaft seal installationNote: Install the seal with the directional arrow outward in order to show the direction of the crankshaft rotation.
Before installation of the crankshaft seal and the wear sleeve, inspect the crankshaft for scratches. Also, inspect the crankshaft for any distortion on the surface that may lead to an out of round condition. Use a polishing cloth in order to remove any imperfections on the crankshaft.
Use 4C-9500 Quick Cure Primer to clean the outside diameter of the crankshaft.Note: The new seal comes with the retaining compound that is already applied to the inside diameter of the wear sleeve.
