Title: HELP - PLEASE - 904/999 Output Bearing
Post by: AJ on March 09, 2010, 02:57:37 PM
OK...I will keep this very brief as I am extremely frustrated and thoroughly confused.

 
The Extension Housing\\Output Shaft bearing in my trans has went south...took a couple months to track down the noise...
 
Pulled it all apart and added external oil filter and 2qt pan...I had the trans rebuilt within 5,000 miles (but this part is not in the overhaul kit as it hardly ever needs replacing, being that it is a ball bearing).
 
So...I call my trans buddy up and have him order the bearing which is WRONG, they sent him the output shaft bushing which is for the 2wds and when he calls his sources they say they can't get it, sorry, not even used...so I start going around town looking for the bearing locally with limited luck.
 
I call my friend up where my Jeep is sitting and he puts a set of Metric calipers on it with the following dimensions:
 
I.D. - 31.5mm (1.2401in)
O.D. - 72.0mm (2.8346in)
W - 19mm (0.7480in)
 
NAPA is able to find me a bearing that is meant for my application (but not thru there system b/c it is terrible and does not have it listed).  They give me the part and it LOOKs close and it is...everything is perfect except that the I.D. is 0.040in too big.  WTF...
 
So, we look at the bearing and find the PN from MRC...what we find is this, after calling SKF (who bought them out, naturally)...
 
According to MRC\\SKF the bearing is a 'custom' bearing by the PN but have no listing for it in there books including the OLD books...
 
What do you guys think is going on here?  Anyone have to change this bearing and run into the same issue?
 
To complicate things more according to Transtar my trans should have a ~2.445in O.D. on the bearing but they do not have a listing for the I.D. and the NEWER Jeeps have ~2.8346in O.D. but they do not have an I.D. listed.   Both of them are almost out with the 2.8in O.D. bearing only having 1 in stock US-wide with no plans of remanufacture and same with the smaller ones...
 
I am going nuts here...I think I may have to get a sleeve made for the bearing I got from NAPA with a press-fit onto the bearing and a slip fit onto the shaft but at ~$80(1hr labor), I can't afford it and really do not trust it even though a proper press-fit is said to hold up fine...I just can't trust it especially when I have my family in the Jeep with me on occassion and work nights with a 50mi 1-way commute...
 
The closest bearing I have found from SKF has the following specs:
 

I.D. - 30mm (1.1811in)
O.D. - 72.0mm (2.8346in)
W - 19mm (0.7480in)
 
Does anyone know if the I.D. can be turned down on the bearing?

I actually called A&A and they were supposed to call me back after 5P...never did...
Thanks to AMCForum I was able to find the Mopar PN (the stealership wanted my VIN aka digging) and I didn't have it at the time...and they want ~$50 for it...
 
I will try A&A again tomorrow as they have it listed for $25 which is MUCH more sensible - as long as the O.D. is correct, of course.
 
One thing that I find interesting - my Jeep is an 82 and all replacement bearings (ie Timken etc) call for COMPLETELY different specs...strange....

Fasco in Fairfield.  Or Fisher transmission.  Same place  He'll have it and get it right.
 
While you're there, get me a tail shaft bushing for a 518.  LOL

The saga continues...called the stealership and the part is backordered, indefinitely...
 
Trying Fatsco now...and no such luck...again it calls for the INCORRECT bearing...geez!
 
He is goig to check in the back himself to see if he can find something...what a friggin nightmare.

*UPDATE*

Mopar sucks, mopar sucks, read all about it...
 
OK - so...I called your contact too, Bob.  His exact words "This is weird...I can find your OD but not your ID and your ID but not your OD".
 
I am thinking I am going to remove the last Chrysler part from my truck which is the transmission...what a friggin nightmare.  My truck is apart, I am not putting it back together with a crapped out bearing...so Chrysler has me (and the rest of us probably) by the balls.
 
Friggin Wonderful!

A&A has em - and only because they were purchased some time in the late 90s he figures...why the hell is the bearing not available without an ETA?  That is ridiculous...if the bearing goes what are people supposed to do replace the WHOLE TRANNY or something?

The bearing fits a very wide selection of vehicles ie 84-02 Jeep Cherokees...geez...(http://moparfins.com/forum/smileys/smiley7.gif)

would it be possible to hone out the housing to use the bearing that matched the ID but maybe had a bigger OD?

None has a larger O.D.  The best I was able to find has a smaller I.D. but the problem is you can't machine bearings...no big deal.  A&A is shipping out either today or tomorrow and I am going to get the Used one from Fatsco as a backup.

And the end of the story....
 
The truck is back together and the trans is as good as new, if not better.
 
It does still have a fresh rebuild on it, after all but it pulls straigt thru all 3 gears and the noise is in fact gone...thank goodness.

I posted this Q on AMCForum.com and here...both are GREAT....
 
How are your V8s running?  I officially get 20MPG w/ my truck by the way...I am leaning towards the Summit K8600 because between the price and everyone raves about it over the Edelbrock cam...
 
This isn't going to happen until the end of summer most likely because I want to convert over to FI while I am there which the Summit cam will work well with due to it's specs. :)
 
GM TBI, have the harness made, just got the correct computer...just need the fuel pump and adapter plate - I plan on letting the ECU control spark as well...

I learned allot about what to do and not do when working a specific goal.  If you want torque, use a short duration, High lift cam.  That will give you the torque you want.  If you follow the thread through its entirety, you'll know exactly what to do to give you the snot you are looking for.  And it will give you the MPG.  It will probably give you 25 when done.
 
I have the porting tools here, and I am loaning my other set to Leanburn.  I have another set of heads to do so don't get too far away.  Have a spring compressor and the lapping tool too.
 
Cam and porting is all you need to do.  Rollers would be a nice upgrade too, and not much more that flat tappets.  Not sure about the upper lubbing on that 390 though.
 
Get yer pipe and slippers.  LOL

There's some torque curves there too around page 10 or 11
