I tried crossing this but did not come up with anything. Does anyone have a cross reference for this number?
Also, if anyone knows a part number for the flywheel ring gear that would be helpful also. Local parts houses list a ring gear for the smaller light duty 168 teeth flywheel.

What engine and transmission are we dealing with, does the truck have a single or dual disc clutch? | | | | | Joined: Jun 2011 Posts: 5,096 Crusing in the Passing Lane | | Crusing in the Passing Lane Joined: Jun 2011 Posts: 5,096 | Easy enough to count ring gear teeth. A set of vernier calipers, carefully used will get your pilot bearing info, readily available, economically priced, simple to use.

The pilot bearing p//n is 904983 which crosses to a Bower 205FF, I can provide Napa part number crosses if they would be more helpful to you, hope that helps.

3702454 changed to 3991408: 168 teeth
3737920 changed to 3991409: 197 teeth
The 3737920, 3991409 numbers cross to a Pioneer part number FRG197B
For what it’s worth my truck has a 292 six cylinder with the 197 teeth ring gear. I mention this in case others come across the same scenario. Thanks again for the help. | | |
