Rebuilding 9" rear. 1957-59 I think. Just put new bearings and crush washer in pinion. Torque to 190. I have read a number of different torque test of pinion specs. 13-15, 25 inch. lb. etc. Can't do test, pinion runs nice and smooth. No resistance at all. What am I doing wrong?
It will probably take more than 190 ft-lb to start crushing the spacer. Once it starts to collapse the required torque drops off.
Ft Lbs Torque has nothing to do with it if you are using a crush collar, you want around 24 inch pounds of drag on new bearings, or a slight drag on used bearings, there is no set torque on crushing a crush collar they all act differently.
the preload of the pinion is important even if your using a solid spacer and shims as stated above in inch lbs all so the preload of the side bearings
more important , the clearance of ring to pinion, OK , maybe not more important , but AS important. I have seen (and heard ) many rearends set up way too close , and they HOWLLLL , I set the clearance a few thousandths looser than specified, ,, ya gotta have some room in there for lube to go between the metal surfaces, ,,, I have set up quite a few that others were afraid to tackle, and haven't had a failure yet,even at over 650 HP,,,,, my process has worked well for me , but, you can go by spec,,, Joe
You have to crush until you have approx. 15 in.lbs. of rotational force. I do it without the seal. Tap the pinion in & out with a br*** punch. Rotate several times to get the bearings to seat. U prefer using a solid spacer vs. The crush sleeve. Posted using the Full Custom H.A.M.B. App!
