I'm attempting to 'crush' a new crush washer while setting up my 9". I have the pinion nut at about 250 lb-ft of torque and the crush washer hasn't even budged. In fact, there's play in the pinion in between the bearings...

Any thoughts on what I might be doing wrong while setting up the pinion?

Not using enough torque. J/K

Takes a lot of torque to make the spacer move the first .001, little easier after that though.

I suspect if I put it in the 'crush-o-matic' I'll blow past the 'knee' of that crush washer and have to start over!

Anyone else?

Don't you mean the Crush Sleeve? and yep, lots of torque to get it to move that tiny bit... then it's touch N go...

Took me more than the 400 ft/lb rating on the impact wrench - we tightened it, (I say we, but I didn't do that part

) but couldn't move it any more, and hit it with the impact - didn't move.

So, we bought a longer bar. I estimate 500 ft/lb on the pinion nut before the preload and drag were correct.

FE: Yes! Crush sleeve...

King: Sounds like what I have to do next! Big breaker bar...

That's why I use the shim spacer - who needs that crush spacer hassle.

I think you can put the sleeve by itself in a press just to help get that initial breakover compression, and then put everything back together and save yourself a little bit of strain. They are a pain.

Just get a solid sleeve and be done with it. I had several different sized made up at a machine shop. Anywhere from .445 to .485 in. thickness. Just set it up with the right one and set your shim thickness and be done with it.

I'm with ckelly and smokey. I've assembled a few and always used the solid spacer/shim spacer with great results.
