Crankshaft Balancer Installation

^ Tools Required
- J 36660-A Torque Angle Meter
- J 41478 Crankshaft Balancer Installer

1. Install the crankshaft balancer using J 41478.
2. Remove J 41478.





3. Install J 44226 to hold the crankshaft balancer.
4. Hold the flywheel or back of the crankshaft. The crankshaft balancer does not have a keyway so the crankshaft could turn when tightening, causing an improper torque.

Notice: Refer to Fastener Notice in Service Precautions.

5. Install the crankshaft balancer washer and new bolt.

5.2. Use J 36660-A to tighten the crankshaft balancer bolt an additional 180°.
6. Remove J 44226.
