You can grind off the excess weld and when it gets close to the right size then file it till the clutch disc fits. But we need to keep the disc a tad loose so it won't bind on the splines. When it gets close you could lap the splined parts together for clearance.
I don't like to jimmy rig or band aid any fix i like to make it right so it lasts. I think we have some great ideas here we just need to see if they will work.
I was already thinking of MIG welding or TIG welding the worn splines a little to build them up them use a 3 corner file by hand to fit the clutch disc to it. If you file carefully you can match the older part of the spline with the welded part. Then you can get the heat treated stuff in a powder form in a can and heat the splines with a torch and dip it into the powder to case harden the new splines. Its really smokey but it works.
I have a farmall main drive shaft here somewhere. If i can measure it and it may or may not need some machine work in a lathe to make the end fit the 4 bolt 154 coulper. If its the correct size to machine we may get lucky. Then cut it to the proper length, machine it to fit the coupler and assemble it and spot the cross hole for the 4 bolt coupling.
The people at IH dropped the ball when they figured the tolarences between the 154 drive shaft and the clutch disc splines. I've seen this a lot in the modern companies when there working with the metric system with tolarences being new to it. Its been a long hard road changing over to the metric system in the US.
