### Installation Procedure

#### Tools Required

J 36660-A Torque Angle Meter

1. Install the seal into the front cover by driving it in from the timing chain side using J 36010 . The J 36010 will properly position the seal in the front cover.
2. Install the front cover gasket. The gasket is reusable and does not require sealer.

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.

4. Install the upper front cover fasteners.

Tighten
Tighten the fasteners to 12 N·m (106 lb in).
