Ensure that crankshaft flange (1) is clean, dry, and free from damage.
Ensure that the gasket surface of the cylinder block is clean, free from damage, and dry. Ensure that the gasket surface of isolating frame (6) is clean and dry.
Ensure that plastic sleeve (3) is squarely installed within new crankshaft rear seal (2).Note: The plastic sleeve is included to protect the lip of the seal as the crankshaft rear seal is pushed over crankshaft flange (1). Do not attempt to install a crankshaft rear seal without the plastic sleeve.
Place the assembly of crankshaft rear seal (2) over crankshaft flange (1). Align dowel (5) with the slot in crankshaft rear seal (2).
Ensure that plastic sleeve (3) is engaged on crankshaft flange (1). Push crankshaft rear seal (2) squarely onto the crankshaft. Ensure that the crankshaft rear seal is seated against the cylinder block. During this process, plastic sleeve (3) will be forced out of the crankshaft rear seal. Discard the plastic sleeve.Note: Ensure that dowel (5) is engaged in the slot in the crankshaft rear seal.
Use Tooling (A) to install two outer Torx bolts (7) at the base of crankshaft rear seal (2). Tighten Torx bolts (7) to a torque of 15 N m (133 lb in).
Use Tooling (B) to install two Torx bolts (4) to crankshaft rear seal (2) at Position (X). Tighten Torx bolts (4) to a torque of 22 N m (195 lb in).
Use Tooling (A) to unscrew Torx bolts (7) by one complete turn.
Use Tooling (A) to install remaining Torx bolts (7). Tighten all Torx bolts (7) to a torque of 22 N m (195 lb in).
