Input Shaft Bearing Press Fit? - 03/29/15 01:43 AM
Rebuilding an 833, new input bearing (307) pretty much slid right on. Is this going to be an issue?
Input Shaft Bearing Press Fit?

It should not slide on and off 
Did the old one slide off? If so it is probally the shaft causing the issue, if it didn't slide off maybe it is the new bearing inner race being to big on the I.D.

Its a new input shaft and a new bearing

What shaft is it? I mean who made it? I have heard some of the aftermarket gear sets aren't top quality machine work

Last input shaft bearing I installed slid on, but I heated it up first.

From Brewers, I want to try to get a hold of Wayne, was planning to put this together tomorrow. Anyone know his username on here? I know its 64Dodge or something but couldn't find it.

use a center punch and put a few divots in the shaft. now press the bearing on.

My new 9310 input shaft was the same way. I consulted Jamie Passon and he said this is normal. I used loctite sleeve retainer and let it set up over night.

Quote:GTX Matt, It should be a press fit but using the correct Loctite is acceptable. I rarely need to do this assembling a trans but it does happen.

No way would I mark up the OD of the input shaft. Each divot is a stress riser and can lead to failure. The outermost parts of the shaft are the most highly loaded.
The Loctite would be my preferred method, and I do this stuff for a living.

I've rebuilt more 833's than I want to admit. I've never had ONE, that the input bearing slid on the input shaft. All had to be forced on, one way or another. Of course I haven't done as many as Brewers has, but still......

As long as the centerline is held and the retaining ring takes up any endplay, it really doesn't matter.

.0002 or more lateral, out of round, movement is enough to wear out the pilot bushing in the cranksahft Don't ask me how I know about that

It's only somewhat normal on the late OD trans ... in my experience only on the rear bearing ... I've never just slid an input bearing on a NON OD trans input shaft.

So you guys are saying my transmission is going to self destruct? I'd like to hear something more than speculation on this. If you haven't worked through this problem please don't muddy the waters.

Is yours working?
I put mine together, used the sleeve retainer. Any lateral play was unmeasurable with the tools that I have and not apparent to the naked eye. The sleeve retainer held well.
I could tap the input bearing off the old input shaft pretty easily with a small ball peen hammer against the retaining clip, so I felt more better about it. This thing gets abused so I guess we'll find out. I'd think the worst that can happen is it wont hold, the input will spin in the bearing, generate heat, and weld itself to the bearing, in which case it will work as designed anyway?
Are they pressed for any other reason than to keep them centered? Reduce heat that can be caused by the input spinning in the bearing?

My last aftermarket input shaft didn't have the clearance issue and the bearing pressed on like a stock unit does. The latest 9310 input shaft has a .000 fit from my measurements so in theory the sleeve retainer will be just fine. Once it's all put together there is really nowhere for the input shaft to go if you think about it. On the other hand not indicating the bell housing will cause problems. To answer your question I am not sure at this point. That said I am going to run it and beat it like it owes me money. I can't really go back because we have out 833 gear sets face plated with Liberty stuff. Let us know how yours works. We are getting into floating on the pond and convertible season around here so my interest in cars wanes seasonally. We might have the red 4-speed Charger running this summer but I have pretty much given up hope lol. Good luck and happy shifting!

I'm never said it's going to self destruct.
I said that the bearing should not just slip on. If you put something in there to lock the shaft to the inner race then you SHOULD be good to go.

Tongue in cheek my good man. I agree on the lack of press fit not being ideal.

Re: Input Shaft Bearing Press Fit? - 04/01/15 07:37 PM
When I thought about how much slop is in the front bearing outer race to a stock case and how much is in the output shaft to the input shaft needle bearings and then on how much is in the pilot bearing to input shaft and what happens when you let the clutch out I imagined that all the slop makes the input shaft try to exit, moves away, from the cluster shaft, correct I like to keep the clearances stock as that has worked for me and probally everyone else on here in stock trannys, correct Add the after market parts into the mix and then you need to know if those additional clearances are designed in or missed in quality check process 
Worst thing that can happens is it breaks and wrecks the car, at speed, correct 
Talk about muddying the waters

Kaboom....then possibly a mushroom cloud?
I think it will be okay and as you know I keep an eye on things.
