So here is the story, I have a new to me 72 3550 backhoe with the 6x4 trans. I used it for a couple months just slipping it in low gear without any fuss but had a few moment where a clutch would have been nice. I couldn?t get the clutch to release so I split it and noticed the input shaft was twisted (cracked splines) not allowing the plate to release among a few other things holding it. Question would be is it worth cutting/ welding the input shaft or just upgrade to the 8x2. Forgot to mention the shaft can not be found and yes I know that shaft is heat treated. What?s your thoughts?
