Another question for you...

I picked up a complete overdrive transmission at an auction two or three years ago. It was disassmbled and came in a crate. I don't recall the production date stamped on it, but it's for a mid fifty-two or earlier stepdown. The old guy's son said that it had a "clicking" sound in it so his father took it apart to fix it, but never got around to doing anything with it. If I were to ponder rebuilding it I'd first have to know if there was any saving the transmission output/ overdrive input shaft (pictured). The pilot shaft on the front of the transmission (not shown) is equally rusted.

It's been years since if seen a trans output/o'drive input shaft. Weren't they chrome plated, or am I confusing that with something else? Is any amount of pitting acceptable on this shaft?

I imagine that the pilot shaft into the trans. would be at least somewhat pitted after blasting as well. As long as a clutch disk slides without binding it should be OK, right?

What media should a guy blast these shafts with? (If they're worth trying to save).

Any other thoughts on the subject would be greatly appreciated!

Thanks guys

Pull that apart and take it to a machine shop and have them hot tank it to see if you can remove the rust that way. They can also guide you on your chances of success.

Providing the internals are okay you should get away with rebulding the unit. In any case keep it for possible parts robbery if you ever get another one. Things to watch out for are wear in the sun gear pinions, and in the free wheeling rollers and hub. Good luck,

Geoff.

Thank you both for your responses. I never thought of hot-tanking the shaft, but I'm sure your right that it's the best method.

Sodium Hydrosulfite works wonders to start with. Or better known as [Iron Out] or [Iron Rid], sold in the local hardware stores or major grocery.
