Add a shim and reuse Crush Sleeve (6 Viewers)

[håvard]

I know its not the right way, but when the shops are closed, and your out of spare parts and you just have to get that diff finished.

I was doing a diff today, and i got a new crush sleeve. But it struck me, if i added a small shim to the old crush sleeve and then crushed it again- wouldnt that do the job?

I have read that some people have done this on other cars, but there is always a couple of guys that says "thats not the right way to do it". Well its not the textbook way. But i just cant see any reason not to do it. Solid spacers often have a stack of shims, so the multiple layer should not be a problem.

Anyone here done this before? Whats your oppinion on this?

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.

I've done it on my trucks more than once. Never had a problem

Thanks! You used the shim trick? Or the pipe and hammer trick?



ibinazbass : Im not sure i did understand what you meant, can you give me a bit more info on how you do that?

 

[ibinazbass]

If you slide the crush leave over a nice thick, strong pipe and then hammer on the crush sleeve you can make it longer again. Measure the length of your current sleeve and try and make it about a 1/8" to 1/4" or so longer. Place the pipe in a vice and then hammer on the raised portion of the sleeve against the pipe. Make sure you be sure to turn the sleeve so it gets to a uniform length. Pm me if you need more info

The shim trick. I had a batch of crush sleeves about ten years ago that would strip
the pinion nut before the sleeve would begin to crush so I'd have to put them in a
press to get the "crush" process started. Once they were crushed most of the way you could finish with the pinion nut. Occasionally I would put them in the press a little too long. That's where the shim came in

You too?

I didn't notice if the current sleeves are more "crushable". The current procedure is measure the desired length of shim (length of sleeve minus end play of pinion), remove sleeve, crush in press until .020-.030" taller than measured, reinstall and crush w/ pinion nut.

Did I mention I hate crush sleeves?

The extra 25.00us for a solid spacer is worth it.

I could use a good source for toyota spacers and shims. Anyone have a good supplier? I have come to hate crush sleeves.

I have used Just Differentials in the past for solid spacers, install kits, gears and ARBs. I think they are out of Washington web site justdifferntials.com.

Not sure off the top of my head , but I think the solid spacer I got last year was from Rock Auto or something like that . Crush sleeves suck , seen so many pinion shafts get stripped from trying to get one started . Only advice is use a heck of a lot of oil and get it pre-crushed in a press .

Thanks for the replys!
Then it should be ok then. I also use the press to get them started. Also none of my own diffs got crush sleeves. The one I did a couple of weeks ago was for a friend. I told him about solid spacer, but he wasn't interested. I don't hate crush sleeves. I just don't trust them for offroading.

How could anyone hate crush sleeves? they're so reliable and they force you to do that periodic maintenance that you otherwise wouldn't need to bother with. Like replacing them after all your rock crawling trips that involve bumping the pinion on a big rock further crushing the uncrushable sleeve and giving your pinion bearings room to move about. Nothing makes for happy bearings than a little room to stretch their legs after months of being so tightly confined

 

[FJ40Jim]

And don't forget that after the pinion flange is crushed in by the big rock, the pinion bearing is brinnelled, which gives more surface area for oil to cling to.

That's good, right?

 

[71-CRUISER]

brinnelled,

My new word of the day. I have seen it in bearings but never knew there was a term for it.

 

[Spike Strip]

Races don't like it either, even with the increased surface area for oil...

 

[lcwizard]

Ah yes, those were the days. ...Before I got my first cruiser there was Cochise my trusty quarterhorse.
All I needed to ride the trail was a saddle, bedroll, rodp a nice brinnel . He always had his favorite.
Well worn and soft so it didn't chafe his cheeks

The first crush sleeve I ever worked with I overcrushed it. I tried adding the shim but the thinner wall of the crush sleeve compared to a solid actually cut the shim in two pieces. Fortunately, I discovered this before the install and replaced it with a solid. This was on a minitruck.

 

[FJ40Jim]

Isn't there a reason the spacer cannot be used with the late crush sleeve pinion gear?
I thought the pinion shaft was also larger OD in the later diffs with crush sleeve, so the space won't fit over it?
