A833 Input Shaft

[powermyster]

Just pulled the gearbox on the car. There was a leek between the box and bell housing.

Is there usually much play on the input shaft when out



Looks like someone filled the shaft where the seal goes and where the pilot bearing goes.
Pilot bearing looks bent out of shape and has been doused in grease.



Looks like I have to pull the shaft and get in to engineers, no lathe here.

Not normal....worn out....

I disagree. In a roller bearing there has to be some play. This is exaggerated at the end of the shaft. If you have this amount of play with the main shaft in place then yes, you have excessive wear BUT if you had already pulled out the main shaft then what you have is pretty normal.

The seal goes in and seals one way. Put it in wrong and it will leak. They possibly installed it wrong and that mess was their fix.

Looks like filler. I’m wondering if the shaft was pitted and worn where the seal sits. Shame to reseat it and it to leak.
I’ll probably leave it standing anyways for a day before reinstalling it see if it weeps

Better get ordering some bits soon

Call Brewer. Play is normal. They may make a seal sleeve similar to a rear axle pinion repair sleeve.

I had a look at the design and it seems there would be a good bit of play in that design. It relay on the pilot hearing to hold it true.

I seen the repair sleeves. See they actually do an input shaft wondering what the best option now. As the front of the shaft is worn too. There is a seized roller bearing in the crank. No pilot bearing bush my engine must have been for auto initially. I gather they are different.

Think I can get the sleeve here locally in Ireland as SKF make them. Anyone any experience with the quality of the new input shafts.

When I bought my car, the transmission was out because the previous owner said "It was making noise". I noticed the play in the shaft (just like yours) and showed it to the guys at Brewers Performance when I was picking up other stuff. He checked it out and said it was fine. Turns out he had something wrong with the throw-out bearing (maybe adjusted wrong) because the back of the pressure plate was all tore up) You are right in that it relies on the pilot bearing to keep it true.

Are you saying you have no pilot bushing? That's not good. You need to have something to support the shaft. If your crankshaft is not drilled for a pilot bushing (like maybe a cast crank) there is another option.

My Barracuda has a 400 with a cast crank and the previous owner put in one of the bearings shown below. It presses into the back of the crankshaft where the nose of the torque converter would normally sit. It will support your shaft. On some transmissions, you might have to cut about 3/4" off the end of the input shaft so it clears and doesn't hit the back of the crankshaft, but if you have already had yours installed, it may have enough pre-drill in the crankshaft to clear. Bearing sits in the crank like shown in the second picture.

Mine has a bearing the there but it look damaged. It’s been packed with grease but I’d say the shaft was spinning in it when clutched.

I was getting an intermittent noise which I thought was the release bearing but that seems fine.

 

[powermyster]

Here is the bearing



Odd bolt in fly wheel too. Same as clutch. Whoever worked on it must have just thrown in whatever fits

The side to side play is perfectly normal.
The epoxy repair on the shaft would bother me and I'd replace the input shaft.

Be careful who you take advice from.

 

[moparnation74]

My post was in reference to the area that is worn out and epoxy was applied to restore it....which I would not even consider reusing......

Hence not normal....worn out........

Funny, the consensus is to replace the shaft....hmm.....guess the advice was correct.....

 

[vintage chromoly]

LOL.
Of course the epoxy repair isn't normal. That's obvious.

The question about the side play and the OP's video representing the question is perfectly normal as Stanton explained in post 3.

Again, be careful who you take advice from.

That what I was referencing to....so what?

I am entitled to.my opinion......

I disagreed with stant just on the basis of it being normal....but your not Stanton so why are you involved....

Piss off.....

 

[powermyster]

Thanks again for the input guys. Gonna pulpe the bearing tonight while there might awake
Pull the flywheel and there is a bit of crud there I’ll check the crank oil seal but think it’s fine.
Am I as well to throw in a mini starter on the rebuild? Are they any better I ther than size? Was thinking of a later model starter not an MSD type

Obviously suffers from the need to be right all the time !!

"but your not Stanton so why are you involved...."
what does this mean?
is it English or is there some punctuation missing
Is this problem getting resolved

Couldn't agree more......lol

That's the way those two operate.....hence is why they are the most disliked....

Post a thread in the general section about "mini starters" and many will chime in with choices.....

Or you can try searching on the forum using the search function above, top right....

Pilot bearing application is for a mid 90s Dakota with a V8: https://www.rockauto.com/en/catalog...transmission-manual,clutch+pilot+bearing,1964

Damn pilot bearing stuck in crack. Even took weight off my larger slide hammer and it’s still no good. Any suggestions before I take an airsaw to it
