Backlash at .003 place your bets.

Has anyone heard of ring and pinion backlash starting out at .003 and working itself out. Rather than blowing up?

I have heard at least on person getting away with it. Most of the posts say noise come from too much backlash like .020+. I just don't want it to lock up on me or something.

Please post your experience.

Yea, I was talking about the backlash between the ring and pinion. I have no clue what my runout is. I did sand the ring and the land for burrs though.

By the way I tried the "match the pinion head with shims method" the first pinion setup and it was way off. I was changing from 2.73 to 3.27s and had to add .008 shim for a total thickness of .040 to mach the 2.73s thickness. I installed it and the patern was off. Then I went to and still have .028 and I think that is still maby .006 to much but the patern is much better.

FYI to those thinking of doing your own. I have read that reusing the factory pinion shim is a popular choice and as it turns out would have worked out ok.
