• | J 42386-A Flywheel Holding Tool |
Important:
• The crankshaft balancer is balanced as an individual component.
It is not necessary to mark the balancer prior to removal. • 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 fourth
passes tighten the new bolt to the proper torque. • The used crankshaft balancer bolt will be used only during the
first pass of the balancer installation procedure. Install a NEW crankshaft
balancer bolt and tighten as described in the second, third and fourth passes
of the balancer bolt tightening procedure. • Make sure the teeth of the tool engage the engine flywheel teeth.
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.
Use one M10-1.5 x 120 mm and one M10-1.5 x 45 mm bolt for proper tool operation.

to 50 N·m (37 lb ft).
Important: The balancer should be positioned onto the end of the crankshaft as straight as possible prior to tool installation.
3.1. | Assemble the threaded rod, nut, washer and installer. |
Insert the smaller end of the installer into the front of the balancer.
3.2. | Use a wrench and hold the hex end of the threaded rod. |
3.3. | Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto crankshaft. |
3.4. | Remove the tool and reverse the installation tool. |
Position the larger end of the installer against the front of the balancer.
3.5. | Use a wrench and hold the hex end of the threaded rod. |
3.6. | Use a second wrench and rotate the installation tool nut clockwise until the balancer is installed onto the crankshaft. |
3.7. | Remove the balancer installation tool. |
Tighten
Tighten the crankshaft balancer bolt to 330 N·m (240 lb ft).
Important: The nose of the crankshaft should be recessed 2.4-4.48 mm (0.094-0.176 in) into the balancer bore.
If the balancer is not installed to the proper dimensions, install the J 41665 and repeat the installation procedure.
