I have been reading here for a long time, unfortunately I need some help. I was doing some grading with my B2400 HST, heard a snap, stopped, found a broken U joint cap sitting on the ground. Upon investigation, I found that the transmission side U joint yolk has completely failed and broke. Would be a pretty simple repair except it is up inside the frame tunnel, way out of reach. Is splitting the tractor nessisary to repair this? I am wondering if I can use a grinder to cut an access panel out of the frame, and either welding it back in place afterwords, or getting a larger steel plate, drilling holes for bolts to be able to have a removable panel. Would this weeken the frame to the point I should not do it? I appreciate any help and responses, thank you all in advance.

Jon- don't know your tractor, but most times the propeller shaft can be replaced without splitting the tractor.
There are a couple roll pins, that when removed, give you enough travel to take it out.
Go to the Kubota website and get the parts diagram for it. Should give you a good place to start.
Good luck!!

Jon - was on my cell phone earlier and don't know how to paste stuff.

Go here, agree to the legal stuff, and put your model in. Should get you to the parts diagram for the shaft.

Again, good luck!

I know I am late to this thread but what im gonna do is cut my shaft off and get a used one. Turn the shaft down a little bit behind the splines so I can slide the couplers back past the end of the shaft. And hopefully cover the shaft with some metal to help protect the shaft from getting wrapped up with weeds.
