Frond wheels lock up on B2400 HSD with bi-speed turn 4 wheel drive

If there is some kind of reference to look for, a piece sticking out, a hollow that lines up with a another piece I'd weld it up. As was said, the gears are damaged so you can't make them any worse, well you can but that's another matter.
Yes the gears are set with the proper backlash, preload etc when done properly from the factory What have you got to lose other than the time to disassemble, weld and reassemble. The weld doesn't look all that good from day one unless a lot of it has been beat off by moving parts. Just my thoughts.............Mike

Thanks for everyone's input. I've been busy so I haven't had a chance to work on my B2400. I'll update this thread when I get a chance.

Now I am not that familiar with the B-series, but I am willing to bet the gear box is also one of the main axle mounting points and the axle pivots on the box. My guess is that maybe the pivot seized and when the axle tried to pivot it tore the flange out of the axle. It may be possible to remove the flange from the gear box and weld it back to the axle and reassemble the unit.

I'm finally putting my front axle back together. I'm stuck. How is the stake nut which holds the bi-speed clutch on the pinion shaft torqued? When I try to torque it the shaft rotates. I don't see any good way to hold the shaft.

Back in business with a new front axle. Total cost of parts and miscellaneous items in the neighborhood of $1000. No cost for labor because I did it all. Edit: I guess I should mention that the axle is an upgraded version of the original. Apparently Kubota had problems with the original axle breaking. So, hopefully, this axle will last longer then the 20 years the old one lasted.

The bi-speed clutch torque limit is set with shims. The procedure is in the service manual. Special tools are required to prevent the axle from rotating during the process.

I had a set of fixtures made for my B1750.

FWIW, I like Bi-Speed Turn and wish it was still offered but it is an expensive option, appreciated by few.

The special tool I used was a pry bar covered in masking tape with which I jammed in the gears. Worked great. My mechanic friend said "There is no way the gears would be damaged while torquing the stake nut. That steel is hard.""

Have a B2400 that front axle was welded on. Seal leaks, did not quite get welded right. Have to add fluid to front axle about every 3 hours, when it sits leaves a puddle. New parts was the way to go.

Properly setting the Bi-Speed torque limiting clutch with shims requires 450 Lbs./Ft, IIRC. This requires fixtures to prevent the front axles from turning.

We must be talking about two different things. According to my manual (page D6-S 15) , the stake nut on the Spiral Bevel Pinion Shaft requires 21.7 to 25.32 Ft-lbs of torque.

You must be talking about the "Bi·speed Turn Clutch Friction Torque" (page D6-S13). I did not check nor adjust it. I assumed it was fine because the damage was to the axle not the bi-speed turn.
