I have a 1983 Jeep CJ5 that just had a engine replaced a year ago inline 6 248. At the same time I had the clutch replaced. The pilot bushing keeps going out on it. I have had it replaced 4 times. It goes out around every 6,000 miles. The last time it went out in 100 miles.
I think the guys at the shop are starting to hate me. I don't think it is the bushing anymore. Maybe they could have bent the spline on the transmission when they reinsalled the engine?
I think they are at a loss..

When you say "goes out" what exactly happens to pilot?

It starts making a honking noise from the clutch area. They say it is due to excessive heat.

Have them check race on end input shaft for scoring. Also check shaft for play maybe input bearing worn. Have them mic. Shaft end and bushing inside diameter. Should not be more than.003-.005 ths.

Another thing that might give you some light. When in first gear only, I take off the shifter shakes really bad.

Sounds like your tranny needs rebuilding

Maybe your front bearing has had it. Letting it "waller" around thus muffing your pilot bushing.

Thanks for divulging that info soon!

What tranny you got?

I just rebuilt my T-150 recently---all new internals, just reused my case!

Keep info coming, We will, at minimum, steer you toward inexpensive, if we can

Roger,

This may be the deal--this would make everything wear--bearings and shafts.

The rear bearing adapter on my tranny, just sorta "sits" in it's hole, in the housing, the transfer case holds it in place, once fastened to the tranny.

If you separate the Tranny and transfer case. 1st, one must pull the shifter housing off, and wedge something in behind the 1st/ reverse gear (I use 2 big screwdrivers, one is just insurance!)---before you remove the transfer case....otherwise the bearing adapter falls out/ gets dragged out the rear of the case.

If you are gonna rebuild the tranny no big deal.............
If you must put it back together after service/ repair of clutch or transfer case...

YOU "ASSUME" the tranny should still be "serviceable", cause it shouldn't have been "Messed With"

No Big Deal???? .....When it falls out, even slightly, the INPUT SHAFT AND THE MAINSHAFT SEPARATE, inside the tranny.....ALL/ MOST OF THE NEEDLE BEARINGS FALL OUT!!!!

If you were not aware--You would CRAM the Rear Bearing Adapter Back in (IT WOULD GO BACK IN!) But now the needle bearings are in the bottom of the case!!!......The Shafts can no longer run "Centered" on each other...Stuff will wear badly, shifting would be bad, tranny noise for sure.

On mine I "wire" the bearing adapter to the case, until it is time to install the transfer case....During re-installation

In the next pics, look at my needle bearings, in the input shaft....then see the surface of the main shaft (Nose, under my thumb) that fits "Snuggly" inside of them. The adapter is the "red thing" on the rear.

Looks like if you separate the 2 housings of your tranny this could happen to yours. Linking you to a pic

http://www.vintagejeepparts.com/Parts_Transmission_07.asp

# 9 in the link is your input shaft, the other shaft and needle bearings go into the back of it.

If someone else let your shafts move apart, needle bearings fall out, in the past---they caused your whole problem!

It's like the continuous 2 piece shaft "running staight and true", NOW HAS A BROKEN BACK!

Heres my pics

Your Turn

Just checking on you---what have you got figured out?

I hate to write all night, then never hear the rest of the story.I do this to help people (I go all out for the CJ People!), I did not sign up here, for $$$, I just started answering questions (Mostly crusading to help the CJs), while I was laid up a long time with an injury. Just concerned if you are/ have been done right.I sorta learned the CJs on my own, finding the correct resources, I have had 6 total, still have the last 2, never drove anything else. Pretty much had little to start with on both, I rebuilt them, by myself. I do know what it's like to be at the mercy of others!

What's going on on your end?

Thank you for checking up on me. I am at the mercy of the mechanic right now. He is giving me the cold shoulder right now and does not want to call me back. He has replaced this thing 4 times and really hates me right now. I hope to get a hold of him this week and tell him to check out the front bearing.
The write up on the last fix he said he took out the transmission and cleaned it up along with the transfer case. It is hard for me to believe that he did not check that front bearing, but you never know.
Do you think that violent shake in first gear at take-off is a symptom of a bad front bearing?
I love this Cj and hate that it is not fixed yet.

What a "PERTTY" "5"!

Did you read the other answers just above you. Do you understand what I'm telling you about the shaft inside the other shaft, and the needle bearings falling out? If not, I can pull out my old parts and show you what I mean with 2 pics that will "Say it all". Let me know, it will not make me long to make the pics. Even though mine has a different tranny---the shafts I'm explaining are very similar, and would cause everything to go out of alignment. Racket and Tearage Upage!(Maybe of more than we have discussed so far!)

GO BACK AND READ MY ANSWER, after you said it's a T-5

Waitin' on you, let me know if you want the 2 pics taken--I do not mind!

NOTHING GOING ON WITH THE CJs, SO I MADE THE PICS ANYWAY, HERE THEY ARE!

IS THAT EZ TO UNDERSTAND--YOUR SHAFTS ARE VERY SIMILAR.

MAYBE YOU CAN NARROW DOWN HOW THIS MAY HAVE HAPPENED (IF IT HAPPENED).

IT DOES SOUND LIKE MORE THAN REPLACING THE BUSHING-I REALLY DO NOT THINK IT'S CAUSING THE OTHER ISSUES, I THINK THE OTHER ISSUES ARE CAUSING IT! FIX YOU BUDDY RIGHT, HE'LL BE GOOD TO YOU!
