If it is long and thin,you could have a bending issue otherwise you should be fine. Let us know when you do have it.I haven't brought it home yet to measure it up. Just assessing if it's something I can do.
Lol. You think I've got the equipment to post heat treat grind?I would always start with repair. If you do not like the way that turns out then you can still make new.
Because of things moving during heat treat, critical dimension are left oversize for final grinding to size after heat treat.
If you have hardness files check the hardness of the shaft in various locations, It likely could be heat treated in only the critical areas
Definitely. The farmer is going to pull the clutch out to send with me if I take it onGet the new clutch disk for a go gage when you do this.
Had to look up 8620.I worked for Durst, a division of Regal Beloit, making John Deere transmission gears and shafts for a little while. Most all of our gears and shafts were made from 8620 steel. HTH.
And I have made a couple of Wabco motor grader hydraulic drive shafts out of 4140 Rc40 which did not run on needle bearings, ( had to make it 2 times because dummy ranch hands did not want to wait for hydraulic oil to warm up in -10 degree F Colorado weather).
It looks like the splines are bent or damaged.Where is the problem with the shaft?
