In attempting to start the crush sleeve on the pinion housing, I tried compressing the sleeve on my 12 ton press and discovered that it must take more than 12 tons. The bolts sheared off on the press and the crush sleeve hasn't budged yet.

Anyone have an idea of how much bigger of a press I need to do this?

Brian, my 40 ton air/hydraulic press works wonders. See you at the shop soon i'm guessing. :D
 
Oh yea! I got all excited at the thought of buying a bigger tool. But it's probably cheaper to buy you lunch instead. Expect a call from me tomorrow.:thumb:

No problem. I would suggest you just bring all your crap with you and you can finish the job at my shop. All you need is the pinion support and related items. :thumb:
 
There was a thread here not long ago about the spacer but there wasn't one available for the 14ff axle. It would actually be pretty easy to make one but you just need to find a source for shims in various thickness that are the correct inner/outer diameter to fit over the pinion but not too large that they interfere with the bearings.
 
I did find some solid spacer kits with shims, but I figured the crush sleeve wouldn't be a big deal with the press. I'll take Scott up on his offer and just get it done. Using a spacer means I gotta make setup bearings and fool around with shims right?

I didn't see one for the full float axle though.
 
The solid spacer would be nice if you ever need to swap yokes or change pinion seals. With a crush sleeve to do the job correctly you must use a new sleeve anytime the pinion nut is removed, a solid spacer you just remove the nut make whatever changes and zip the nut tight and you're done.
 
Brian, I just put one together a couple weeks ago and mine took right around 19 tons to begin crushing. I also tried it on my 12 ton at home and quickly decided that it wasn't gonna do it.

I've never changed a crush sleeve out when swapping a yoke... Always just retorqued it down snug and never had a problem.
 
This job is now done. It took 16 tons before the crush sleeve started to crush. We finished the job on the work bench with the air impact and the in/lb torque wrench and finished with a rolling resistance of 33 in/lbs with NEW bearings (spec is 25-35 in/lbs)
 
nice, had to take mine to a friends shop as well.
 
In the near future i'm going to swap to a 1410 yoke i've had forever and when i do this i'm going to make a solid spacer and find a proper shim pack so i don't have to deal with crush sleeves anymore.
 
I remember changing to a 1410 yoke with the 4.1 gears, and swapped the crush sleeve, then had to do it again when i did the gears a year later. A solid spacer w/ shims id be sold on.
 
Yes, I think that a kit would sell reasonably well. I would be interested. The crush sleeve is an annoyance with the 14 that I would be happy to be rid of.
