This one's got me stumped. New 350 gear set in a 9" N case Datona Pinion support. This is a noname Summit gear set. 10 on the pinion 35 on the ring gear, with paint match marks, all lined up. NO pinion depth marked, no gear lash marked. I used the .020" shim that was on the pinion support when it had 430 gears in it . In stalled the gear on the Locker as usual 200 deg. hot snugged the ring gear bolts. let it cool down and released the bolts then torqued to 85 Ftlbs. 2 steps. installed the carrier and checked run out , less than .002" great. adjusted the carrier nuts to 0 back lash then tightened the pinion side till I had 010" back lash. Checked in 4 places 10,12, 12, 11 then checked the starting point again and it was .008" spun it 360 deg. and checked the same place and it was .004" spin it one turn again and it was .008' then again and it was .012" what the ..... is up?
Any one have any ideas?

OK, that's good.
I would suggest that you take the ring gear back off and rotate it 180 degrees, then check it once again. Cheap non USA gear sets are not quite as precise as the beter brands.

I pulled the ring gear off of the carrier and wire brushed the gear and pinion, reassembled (180 out from the first time) and the back lash came in ok. There is still some variation between revolutions but it is running at .010 to .012. Did not find any burrs, the back face runout was within .002" the same as before.
Thanks

Glen,

Tell them abou the car this 3rd member is going in.

I saw it at Arron's shop and it's obscene the amount of money this Doctor is putting into this '67. The wheels are $3,500 alone. Griggs racing is involved, and Arron is building and installing a 750 hp blown 408 engine and cage for it. It will be a road racing car.

Way too much money involved. Car is a 68 Coupe going to be one BAD Track Eater. I sold the Doc my 69 Ranchero, he was going to pull the 428 and build a Cal Special Big block car. Then he desided to go for a road race car in the American Thunder series. But he has changed again. Oh buy the way they installed the power steering in the Ranchero freshened the brakes and now it's one of the fastest cars in Calastoga, His son has the radar ticket to prove it. LOL
