What is the purpose of a pinion crush sleeve?
Moderator. It’s not for bearing preload it’s like a lock washer for the pinion nut. It springs back around . 015 and keeps a constant pressure on the pinion nut through the front pinion bearings inner race and yoke.
Can I reuse pinion crush sleeve?
The best way to reuse a crush sleeve is to slide it over a piece of pipe and hit with a hammer to make it longer again. It won’t take as much force to crush it again but will ultimately do the job.
What does pinion preload do?
Pinion bearing preload is measured in inch-pounds and is a measure of the rolling resistance of the pinion bearings after proper torque has been applied to the pinion nut. If the preload is too loose then remove the shims so that the bearings will be tighter against the races and increase the preload.
How do you fix a loose pinion bearing preload?
Use an inch-pound torque wrench to check the preload. If the preload is too loose then remove shims so that the bearings will be tighter against the races and increase the preload. If the preload is too tight then remove the pinion gear and add shims so that the bearings will not be as tight against the races.
Where are the shims on a GM crush sleeve?
You don’t install the crush sleeve or spacer and shims to check pinion depth. They both are used to set the pinion bearing preload. The shims that control pinion depth on a GM are installed between the rear pinion bearing and the pinion gear itself.
What to do if your hot rod crush sleeve is too tight?
If you find that one shim gets the bearings too tight and adding .001 makes them too loose then you can use sand paper on a flat surface to hone about .0005 off of the spacer to get the preload where you want it.
