Crush Sleeve?

[ajstager]

Dose anyone know a good place to find a replacement crush sleeve for the rear diff pinion seal? I have checked at all the local places and have yet to be able to find one. Any help would be appreciated it’s a 1970 c-10 2wd

Thanks.

GM still sells them for the 12 bolt, I'm sure they sell them for the 10 bolt.

Mark the nut and pinion stem before loosening the nut with a center punch, and count the threads that stick out on the pinion. Remove the nut and yoke, reinstall to the same spot. That way you don't need a new crush sleeve.

This has me a little concerned. The crush sleeve is not a thing to be "messing with". It has absolutely nothing to do with the seal, so there is not reason to be in that deep.
You are asking for trouble here. It is not a simple thing to get that thing crushed in the first place and you really should have the differential out when you do it.
Unless you are replacing bearings, there is no reason to put in a new crush sleeve, and bearing replacement is not a simple procedure.
It takes a complete set-up/inspection process, best left to a professional.
If the bearings are worn, so are the gears. You can't "just replace" the bearings....it will howl. (for the rest of it's life)

TTT , I am drawing a blank on the sleeve he wants... for the end of crank shaft , rear trans shaft ,pinion shaft. Not a crush sleeve but for worn shaft ,about 40 to 50 bucks worth.

You're talking about a "speedi-sleeve", that installs on the pinion yoke to provide a new seal surface. Those should be available at any NAPA or local parts store as well. I thought he was looking for a crush sleeve, which you shouldn't need to replace if you're just doing the pinion seal.

We took apart the the whole rear diff. The pinion seal was leaking and we needed to redrill the rear axles to make them 5lug. The crush eleven comes off with the pinon and yoke needed to replace the seal. I origonally was going to replace the crush sleeve but I found the correct way to retorque the pinion using the old sleeve stated in the overhaul manual... Which says to torque the nut on the pinion until 5 to 10 in/lb is needed to spin the yoke. So looks like i don't need a new sleeve.

Has anyone had any experience with this method and or reusing the crush sleeve (with the existing bearings) ?

Mine was making a noise after the DS tore loose, so I wanted to do a rebuild of my diff too, but at the time I just torqed the nut real tight on the CS till the the noise went. That's over a year now, not ideal i know, but I was going to buy a new bearing overhaul with CS set from http://www.drivetrain.com/parts_cata...haul_kits.html
but now I have Longhairs words ringing in my ears.

New seal on the front, pinion installed, torqued to 5-10 In-lbs so we have the 1lb of water in the bottle and then move it 5-10in out from center of the pinion.
put the rest of the rear end back in, and the remade 5bolt rear axles and new 72 drums

Great job mate!! this is giving me the confidence again to tackle mine, although I wish you had more pics of the dismantle and build.
That bottle of water trick was pretty neat...BUT! I'm probably being really dumb here...what did you torque to 5-10 in-lbs? because the pinion nut requires a lot more than that, the pinion seal needs to be hammered on, so I don't get what you torqued & to such a low spec...
Did you renew all the bearings or just the crush sleeve? and how difficult was the job? I've rebuilt my TH400 so I'm not sure why I'm struggling with the idea of this one.

[LONGHAIR]

He is refering to the "rotating torque" of the pinion itself.
But again I will caution you (and everyone else), it's not a good idea to "mess around" with it. Even replacing pinion bearings can cause a howl because it moves the pinion (back where it should have been), but the wear has already happened. I'm not saying that it will destroy the gears immediately, but they will be noisey. The degree of wear in the bearings, and how much corresponding wear is on the gears, would determine the lifespan of the gears after that.

Bottom line, do it all....or don't do it at all.

Changing the seal is ok, but nothing deeper.

Thanks mate, I understand it now....i'll take your advice on that and do the lot, seeing the bearing rebuild kit advertised was what made me think I could get away with just that.
