Question....


I compaired the shaft to other shaft like items around my shed and it is really not much smaller than the output on the tranny or the splined part of the pinion and both of those will see a great deal more stress so maybe it will last.


More talk less do. My buddy called me up last night while on my weekly 120 mile trek up the coast, and he mentioned just making the coupling splined on one end for the output for the first tranny and to keep the other side of the coupling unsplined. So what you would do is just weld the end of the coupling that is un-splined to the second tranny ( the Rock Box) so you would not have to spline it and remove any metal making the shaft even smaller than it already is.


My thoughts where this... Although you would keep the shaft size as large as can be welding the coupling on the shaft would weakin it a great deal. And you would never be able to replace the input shaft bearing on the second tranny because of having the welded the coupling to the shaft it is on( I dont really see that being a big deal because the bearings last a very very long time.

I am thinking we should just spline the input shaft of the second tranny (the Rock Box) and get a coupling made to made both input and output shafts together......which was the orginal plan...


any thoughts from the peanut gallery???

Those shafts are hardened, I would not weld to them without getting it heat treated

Dude I have some pics for your .. maybe some good ideas.

ex nay on the welding... Got a quote for 250 for the coupling tonight from a shop. But will they dont do splining so I think I'll have to find a shop that does the splining as well. I rather just get everything done at one joint.


But right now I am going to have to find out how I can get measurements for the shafts and splines..... Can I just get a digital caliper and measure everything up?

A couple of years ago, I thought I'd read that someone made couplers using the splined portion of a clutch disc. I thought it would be neat to do an SM465 to Spicer 3053A (and heavy as hell) using the stock 10spl SM465 coupler to the clutch disc center for a 3053A.

I've heard that the stock couplers mating SM465-NP205 (I think) wear out, necessitating their replacement. Not sure how much wear it takes to matter, but it might be nice to be able to make cheap couplers. Clutch disc center TIGed to LC TC spline, then sleeved?

I had thought of somthing along those lines, but would use the gear that goes on the output shaft on the tranny inside the t-case.


p.s. thanks for the pics man.

Question,
does anyone know off hand if you can heat treat bearings. Becuase if i go with the welding option for the input ill have to get the bearing heat treat along with it.

call bobby long and ask him. He is the super axle guru..

We make bearings where I work.Actually I guess I make bearings.99% of all our bearings get heat treated during production.Remember that they shrink and grow during heat treat.Makes my job fun some times.You wouldn't want to heat treat a assembled bearing.
