#### Tools Required

J 36660-A Torque Angle Meter

1. Coat the inside surfaces of the bearings with engine oil.
2. Install the connecting rod cap and bearings.
3. Install the connecting rod nuts.

Tighten
Tighten the nuts to 20 N·m (15 lb ft). Evenly turn the nuts an additional 75 degrees usingJ 36660-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.
