Default Input Shaft Options

Is there a place to find a cost effective replacement for input shafts? I have several input drums that would be serviceable if I had a shaft to press in. The old shafts were worn on the bearing surfaces so they are no longer any good. Only thing I can find affordable are drum and shaft sets.

Dang my fault guys. 4l60e. I need a 1994, 2003, and a 2007. I wonder if anyone has tried welding up the surfaces and turning them back to spec.

Given the cost of quality used drums or even new drums...there's 0 way I'd consider welding up a drum and machining it back true
I don't even think I'd consider machining and pressing in a bushing to restore the bore

Basically you need gen 2, a gen 3 without ISS and a gen 3 with ISS. I am retired and closed my shop. I have some left from over the years. I will look and see what I have to day to see if I can help. I know some are already pressed out cleaned, loc-tite added and pressed back into the drum making them ready to go.

How many of each are you looking for?

I meant for this to apply to the input shaft, not the drum. I have drums in good shape.

That would be awesome!

1 of each. I have three good drums that I have pressed the shafts out of. Well two good ones and one questionable. Has minor galling where the shaft came out. I pressed the shafts out due to the bearing surfaces were worn and grooved.

Not practical. You would 1 need a very good welder and I mean both the person and machine, A very nice lathe at least if not CNC and lots of time, Time you were done you could likey buy a billet shaft for the same price or close as it would be very time consuming .

The time invested alone would likely rival the cost of a billet shaft
Even if it didn't...these shafts are just as plentiful as the drum. My comment on effort vs benefit stays the same

I'd worry about the integrity of the shaft if this was done. Also the press fit area of this shaft has feed holes for oil so you'd have to take additional care around them.
Spray weld and finish grind would be the best bet and just seems silly for this application

Welding an Input-Shaft will completely change the Shaft down to the way the Molecules are arranged...

The structure and Heat-Treat will be Lost.
