Tools Required

1. Remove the accessory drive belt. Refer to Drive Belt Replacement - Accessory .
2. Remove the air conditioning (A/C) drive belt, if equipped. Refer to Air Conditioning Compressor Belt Replacement .
3. Remove the fan shroud. Refer to Cooling Fan and Shroud Replacement in Engine Cooling.
4. Remove the starter motor. Refer to Starter Motor Replacement in Engine Electrical.

Notice: Refer to Fastener Notice in the Preface section.





Important: 

•	Ensure that the teeth of J 42386-A mesh with the teeth of the engine flywheel.

•	The crankshaft balancer is balanced as an individual component. It is not necessary to mark the balancer prior to removal.

5. Install 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 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.




7. Use J 41816 and J 41816-2 in order to remove the crankshaft balancer.
8. Remove J 41816 and J 41816-2 from the crankshaft balancer.
9. Clean and inspect the crankshaft balancer. Refer to Crankshaft Balancer Cleaning and Inspection .

Important: 

•	Ensure that the teeth of J 42386-A mesh with the teeth of the engine flywheel.

•	The used crankshaft balancer bolt will be used only during the first pass of the balancer installation procedure. Install a NEW bolt and tighten as described in the second pass of the balancer bolt tightening procedure.

•	The crankshaft balancer installation and bolt tightening involves a four stage tightening process. The first pass ensures that the balancer is installed completely onto the crankshaft. The second, third, and forth passes tighten the new bolt to the proper torque.

Important: Position the balancer onto the end of the crankshaft as straight as possible prior to tool installation.

1. Install the crankshaft balancer onto the end of the crankshaft.



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

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

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

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

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

2.4.	Remove the tool and reverse the installation tool.

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

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

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

2.7.	Remove the balancer installation tool.

Notice: Refer to Fastener Notice in the Preface section.




3. Install the used crankshaft balancer bolt.

Tighten
Tighten the USED bolt to 330 N·m (240 lb ft).

4. Remove the used crankshaft balancer bolt.

Important: Recess the nose of the crankshaft 2.4-4.48 mm (0.094-0.176 in) into the balancer bore.

5. Measure for a correctly installed balancer.

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

6. Install a NEW crankshaft balancer bolt.

Tighten

1. Tighten the bolt a first pass to 50 N·m (37 lb ft).
2. Tighten the bolt a final pass to 140 degrees using J 36660-A .
7. Remove J 42386-A and bolts.
8. Install the starter motor. Refer to Starter Motor Replacement in Engine Electrical.
9. Install the fan shroud. Refer to Cooling Fan and Shroud Replacement in Engine Cooling.
10. Install the A/C drive belt, if equipped. Refer to Air Conditioning Compressor Belt Replacement .
11. Install the accessory drive belt. Refer to Drive Belt Replacement - Accessory .
12. Perform the crankshaft position (CKP) system variation learn procedure. Refer to Crankshaft Position System Variation Learn in Engine Controls.
