Once the crankshaft front 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 front seal.Note: Use Tooling (H) in order to clean the outside diameter of the crankshaft and the inside diameter of the crankshaft front seal.Note: Apply Tooling (J) to the outside diameter of the crankshaft.

Place crankshaft front seal (1) (not shown) in position on Tooling (D). Install Tooling (D) to the crankshaft with Tooling (E) .Note: Install the crankshaft front seal (1) with the arrow that shows the direction of the crankshaft rotation toward the front of the engine.
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.
Install Tooling (G) and Tooling (F) onto Tooling (D) .Note: Lubricate the face of Tooling (F) before installation.
Tighten Tooling (F) until Tooling (G) contacts Tooling (D) .
Remove Tooling (F), (G), (E), and (D) from the crankshaft. Check the crankshaft front seal (1) (not shown) for the correct installation.End By: Install the crankshaft vibration damper and pulley. Refer to Disassembly and Assembly, "Crankshaft Vibration Damper and Pulley - Remove and Install".
