so the thread was mis-directed....
You do some fine, fine work there!
This is a much simpler problem. I can explain. No pix (yet).
Differential has a small plate bolted to the ears with a short pipe welded to it, centered.... There is a 5/8 hole drilled crosswise in the pipe.
Then the piece that broke was a LO-95 lovejoy coupler. 1 inch bore, to fit the hydraulic motor. I removed the ears and welded a piece of pipe to this one as well, with the cross wise hole.
Drive shaft is simply a piece of pipe that slides over the ends with 1/2 bolts for pins. Worked like a charm, at this low RPM. However!!!
Two things went wrong. 1st, I know I am not supposed to MIG weld to cast iron.... Second the cast iron Lovejoy coupler is rated at 16 ft. lb. The motor can go well over 100 ft. lb. torque.... ka ching :bang:
What I am going to replace it with is a 1 inch chaft coupler made of steel! The rest of it is just fine as far as I am concerned.... could be better, but I need to get this thing splitting wood quickly! :biggrinbounce2:
