Tools Required

1. Remove the air conditioning (A/C) drive belt. Refer to Air Conditioning Compressor Belt Replacement .
2. Remove the power steering gear. Refer to Steering Gear Replacement in Power Steering System.
3. Remove the starter motor. Refer to Starter Motor Replacement in Engine Electrical.
4. Remove the right transmission cover and bolt.




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: Make sure that the teeth of the flywheel holding tool mesh with the teeth of the engine flywheel.

5. Install the J 42386-A and bolts.

Use one M10-1.5 x 120 mm and one M10-1.5 x 45 mm bolt for proper tool operation

Tighten
Tighten the J 42386-A bolts to 50 N·m (37 lb ft).




6. Remove the crankshaft balancer bolt.

Do not discard the crankshaft balancer bolt. The balancer bolt will be used during the balancer installation procedure.





Important: For manual transmission applications, note the position of the crankshaft balancer before removal. The balancer does not use a key or keyway for positioning. Mark or scribe the end of the crankshaft and the balancer before removal. If replacing the crankshaft balancer, note the location of any existing balance weights (if applicable). Install new balance weights into the new crankshaft balancer (if applicable) in the same location as the old balancer. A properly installed balance weight will be either flush or below flush with the face of the balancer.

7. Mark or scribe the crankshaft balancer and the end of the crankshaft.

Note the balancer installed position on the crankshaft for assembly.

Refer to Engine Balancing




8. Use the J 38416-B and the J 41816-2 in order to remove the crankshaft balancer.
9. Remove the J 38416-B and the J 41816-2 from the crankshaft balancer.



10. Not the position of any crankshaft balancer weights (if applicable).
11. Clean and inspect the crankshaft balancer. Refer to Crankshaft Balancer Cleaning and Inspection in the Engine Unit Repair Manual.

Important: 

1. Using the old balancer as a reference, mark or scribe the NEW balancer in the same location (if required).

Refer to Engine Balancing

2. Install balance weights into the NEW balancer (if required).

Refer to Crankshaft Balancer Cleaning and Inspection





Important: Align the scribe mark on the balancer with the scribe mark on the crankshaft.

The balancer should be positioned onto the end of the crankshaft as straight as possible prior to tool installation.
3. Install the balancer onto the end of the crankshaft.



4. Use the J 41665 in order to install the crankshaft balancer.

4.1.	Assemble the threaded rod, nut, washer and installer.

Insert the smaller end of the installer into the front of the balancer.

4.2.	Use a wrench and hold the hex end of the threaded rod.

4.3.	Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto the crankshaft.

4.4.	Remove the tool and reverse the installation tool.

Position the larger end of the installer against the front of the balancer.

4.5.	Use a wrench and hold the hex end of the threaded rod.

4.6.	Use a second wrench and rotate the installation tool nut clockwise until the balancer is installer onto the crankshaft.

4.7.	Remove the balancer installation tool.




5. Install the used crankshaft balancer bolt.

Tighten
Tighten the used crankshaft balancer bolt to 330 N·m (240 lb ft).

6. Remove the used crankshaft balancer bolt.

Important: The nose of the crankshaft should be recessed 2.40-4.48 mm (0.094-0.176 in) into the balancer bore.

7. Measure for a correctly installer balancer.

If the balancer is not installed to the proper dimensions, install the J 41665 and repeat the installation procedure.




8. Install the NEW crankshaft balancer bolt.

Tighten

1. Tighten the new crankshaft balancer bolt a first pass to 50 N·m (37 lb ft).
2. Tighten the new crankshaft balancer bolt a second pass to 140 degrees using the J 36660-A .



9. Remove the J 42386-A and bolts.



10. Install the right transmission cover and bolt.

Tighten
Tighten the right transmission cover bolt to 12 N·m (106 lb in).

11. Install the starter motor. Refer to Starter Motor Replacement in Engine Electrical.
12. Install the power steering gear. Refer to Steering Gear Replacement in Power Steering System.
13. Install the A/C drive belt. Refer to Air Conditioning Compressor Belt Replacement .
14. Perform the crankshaft position (CKP) system variation learn procedure. Refer to Crankshaft Position System Variation Learn in Engine Controls - 5.7 L.
