TRX300FW rear diff rebuild

3621 Views 5 Replies 5 Participants Last post by  daerhldgs2
Does anyone know the pinion preload setting on the rear diff? I guess I also need the backlash specs. The manual I bought for the ATV said that setting up the rear diff was a very complicated procedure and special tools are needed. Obviously, the manual is of no use in this case.

I have the tools I need and have set up many diffs for jeeps and cars...just need help with the specs.

Can anyone help?

If you have between 6 and 12 thou lash youll be fine. there are washers to get the crown gear the proper distance from the pinion gear, but the pinion seems to only have one way with no way to set it deeper. I just shimmed my crown gear to get the right lash and it seems fine.
