## Crankshaft Rear Oil Seal Replacement One Piece Design

### Removal Procedure

Notice: To prevent oil leaks and seal damage, the engine's oil pan must be removed if the rear oil seal carrier requires replacement.

1. Remove engine oil pan. Refer to "Oil Pan - In Chassis" removal procedure in the General Information section of this service manual.
2. Remove rear oil seal assembly bolts and discard bolts. New bolts are supplied with seal kit and will be used for installation.

Notice: Do not pry in the area of the crankshaft flange sealing surface.

3. Pry the outside edges of rear oil seal carrier away from engine block and remove seal carrier.
4. Remove original RTV from engine block and oil pan using scraper or 3M Scotch-Brite® pads, or equivalent.

Notice: Do not use petroleum cleaners such as mineral spirits. They leave a film onto which RTV will not stick.

5. Clean the engine block sealing surface with a chlorinated solvent, such as brake cleaner Saturn P/N 21007432, alcohol, or equivalent.
6. Check the oil seal lip contact surface of the crankshaft for rust, scratches, or damage. If rust is present, remove using a fine 3M Scotch-Brite® pad and clean thoroughly.

### Installation Procedure

Important: The rear crankshaft oil seal assembly comes with a plastic installation sleeve. The installation sleeve prevents the oil seal from rolling during assembly.

1. Do not remove the sleeve from the seal assembly until after installation to the engine block.
2. Apply a 5 mm (0.2 in) diameter bead of RTV to the stamped metal seal assembly as shown.

Important: Assemble while RTV is still wet, within 3 minutes. Do not wait for RTV to skin over.

3. Apply a film of oil on the crankshaft scaling surface where the seal rides.
4. Install the seal assembly to engine block and crankshaft with installation sleeve still in place in seal assembly.
5. Install the four new (17 mm) rear crankshaft seal assembly bolts provided with seal kit.

Tighten
Tighten the crankshaft rear oil seal assembly-to-block to 11 N·m (97 lb in).

6. Remove installation sleeve and discard.
7. Install engine oil pan. Refer to "Cylinder Block Assembly" procedures in this section.
