Full 40 spline 14 bolt rear

blacksheep10 · Dec 8, 2017

just to test it, I cut a grade 50 (mild steel) rotor for a rzr front. So 60 mph boiling the brakes down on woods racing, up and down cooking them. Never had a problem

PM me details of floater cups if you don't mind.

I've got nothing against Weaver, but if that other company makes it better/cheaper, I'm interested.

cavfab also makes cups. Theirs are for "Super 60" unit bearings on a 3.5" axle tube although theres plenty of meat to bore them for a bigger tube if needed. I dont see them on their website anymore but I purchased a set from them about 6 months ago and they were about 1/2 the price of the weaver fab cups. They may not be making them anymore but its probably worth a call to them.

Did you slot, drill or vent them in any way or are they solid?

Slotted

The biggest challenge I'm facing currently is the re-tubing of my axle. I've got the tubes cut down and the rosette welds drilled out, but I haven't pressed the tubes out of the center section. I've read that it could possibly take 30+ tons of force to get them out. Does anyone here have any experience?

I've pressed axle tubes out with a 20 ton harbor freight press. I've also pressed in short side tube with a chain and bottle jack. Where there is a will, there is a way. Make sure chain is up to task...........just sayin.

You were the one I was thinking of when I said it has been done "hillbilly style" :rolf:

My plan is to machine a "press plate" about 0.050" diameter smaller than the housing I.D. and then hope that a harbor freight press can get the job done. Worst case is I'll have to find someone with a bigger press. I appreciate the feedback. You've got my hopes up!

I have done 14 bolts with a 12 ton harbor junk press. Heat and press makes it easy......

That setup is basically what I had envisioned. Looks like I'm on the right track!

For pressing out old tubes: Cut old tubes off within a couple inches of center section. Measure ID of axle tube, cut some 1/4 scrap where it will easily fit into axle tube and weld it up. Only weld one side, press out and then do other side. To press out, we used a piece of round tube, think it was an old 2.5" 1/4 wall link we cut to length to run into housing to press out old tube.

Attached picture of creative axle tube pressing. Little heat on housing helped.

You left out the part where you almost died

Thanks for the details.

That's an interesting fixture you came up with! What ever get the job done... right? Hopefully there were no trips to the ER.

Hopefully Fire Freak doesn't feel like his 40 spline thread has been totally derailed by my questions and comments.

First chain was not up to task. LOL

Got a different chain, added a little heat to the housing and actually a large hammer pecking on housing helped things move into placed pretty easily.
