Tools Required

Notice: Ensure both components are aligned correctly or serious engine damage will occur.

1. Install the EN-48585 into the end of the crankshaft.
2. Install the damper onto the EN-48585 . Use care to properly align the keyway and flats on the damper with the oil pump drive.



3. Install the J 38122-A .

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: Always install a new crankshaft damper retaining bolt and washer.

4. Install a new retaining bolt and washer. Use the J 38122-A and a breaker bar in order to prevent the crankshaft from rotating when tightening the bolt.
