How much movement should a A833 input shaft have

[70chall440]

As the title says, how much movement (radially and as in up/down left and right)? I have this trans that was supposedly in a 68/9 RR that was in a front end collision, the bearing retainer was cracked at the base but there doesn't appear to be any damage, the inside looks perfect but I can see the input shaft move inside some. I put a dial indicator on the input shaft and I can move it like .080"

Biggest folly in the car hobby.

If you read the repair manual there is no specification for this. Because it doesn’t matter and no accurate way to measure it.

The input shaft has a front bearing. It is a ball bearing not a roller bearing. With trans out of the car only one end of the input shaft is supported. With trans in the car the front of the input shaft is supported by the pilot bushing in the crankshaft. Then it will be held solid.

Without the front of the input shaft being supported, it should have movement in it.

Ok, thanks I was kind of thinking the same way but I am not a "transmission" guy per se so I thought I'd ask.

The ball bearing can wear but, must be out of the case to check. The outer race should be tight on the balls when applying pressure back and forth. As wear occurs the outer race will move but, that is subjective and most BB will work fine with a little wear.

In short - the input shaft will have some movement up and down - maybe 1/8" or so ? no accurate measurement but it will have play unlike say a newer Tremec ---
