90. Crankshaft Balancer Installation

Crankshaft Balancer Installation

Tools Required
^ J41478 Crankshaft Front Oil Seal Installer
^ J41665 Crankshaft Balancer and Sprocket Installer
^ J42386-A Flywheel Holding Tool
^ J45059 Angle Meter





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 4 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.
^ Ensure the teeth of the tool engage the engine flywheel teeth.

Notice: Refer to Fastener Notice in Service Precautions.

1. Install the J42386-A and bolts. Use 1 M10 - 1.5 x 120 mm and 1 M10 - 1.5 x 45 mm bolt for proper tool operation.
Tighten the J42386-A bolts to 50 Nm (37 ft. lbs.).





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

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





3. Use the J41665 and the J41478 in order to install the balancer.
1. Assemble the J41478 threaded rod, nut, washer and the J41665 installer. Insert the smaller end of the installer into the front of the balancer.
2. Use a wrench and hold the hex end of the threaded rod.
3. Use a second wrench and rotate the installation tool nut clockwise until the balancer is started onto crankshaft.
4. Remove the tool and reverse the installation tool. Position the larger end of the installer against the front of the balancer.
5. Use a wrench and hold the hex end of the threaded rod.
6. Use a second wrench and rotate the installation tool nut clockwise until the balancer is installed onto the crankshaft.
7. Remove the balancer installation tools.
4. Install the used crankshaft balancer bolt.
Tighten the crankshaft balancer bolt to 330 Nm (240 ft. lbs.).
5. Remove the used crankshaft balancer bolt.





Important: The nose of the crankshaft should be recessed 2.4 - 4.48 mm (0.094 - 0.176 inch) into the balancer bore.

6. Measure for a correctly installed balancer. If the balancer is not installed to the proper dimensions, install the J41665 and repeat the installation procedure.





7. Install the NEW crankshaft balancer bolt.
1. Tighten the crankshaft balancer bolt a first pass to 50 Nm (37 ft. lbs.).
2. Tighten the crankshaft balancer bolt a second pass to 140 degrees using the J45059.
8. Remove the J42386-A.
