Exactly when was the noise there....with the clutch pedal right out vehicle in N?Armyspecial wrote:Ok, started the Jeep tonight, the noise was stilll there but went after a few moments. I assume this was the result of the Oil making its way into the bushing? There is no noise now, so have i just fixed the problem for the moment, but it will return? Richard

Re: Clutch Thrust Bearing
No. If you read my previous post I have tried the lubrication suggestion first.

Re: Clutch Thrust Bearing
I know this is an old post BUT
Armyspecial, I am wondering what ended up fixing your problem. I am having the same issue right now. I am not sure if it is the TO Bearing or the pilot bushing. I am close to drilling a hole in the TO bearing and pumping some grease in to see if that is temporary fix for a while.
I have a video of mine that I can send or text if anyone is interested in helping.
thanks
Chris

Re: Clutch Thrust Bearing
to summarize....
1) NOISE can come from the disk or incorrect clutch finger adjustment or a bad T/O bearing or the flywheel bushing.
2) The flywheel bushing MUST be lubricated before installation
3) The flywheel bushing is SUPPOSED to be reamed to size after installation or it may bind on the main gear
4) If the main gear and bushing are binding, the squeeling may be from the bushing turning in the flywheel or from the dry main gear turning in the bushing.
If you suspect that you forgot to properly lube the bushing/main gear....you should try to jack up the rear of the jeep , remove the insp. cover and get some OIL on the main gear AHEAD of the T/O bearing. It is a longshot but we did it with Dave's jeep and it worked. Otherwise pulling the T-84 out and getting a little oil in the bushing and/or a bit of GREASE on the tip of the main gear is the next option.
however....checking to see if the T/O is dragging on the clutch fingers when idling in neutral should be done FIRST. Also, watch the action of the T/O and clutch with a good flashlight while someone presses the clutch pedal down when idling in neutral to see if that causes the squeeling or if it only occurs when in gear and shifting.

Re: Clutch Thrust Bearing
Remember, the Clutch Pilot Bushings are made of graphite impregnated bronze, they need no lube except for the little dab of grease indicated by the manuals when first installed.

Re: Clutch Thrust Bearing
Twenty years of long hot summers may cause a flywheel bushing to lose some of its' ability to lubricate the bushing and the main gear. In addition to that, it is soft enough to be distorted when installed and if so, it may bind on the main gear and cause noise, heat and wear.

Re: Clutch Thrust Bearing
I spent some time on the M38 this weekend. I adjusted the linkage to the correct lengths. I jacked the rear up and used 3 in 1 oil. I lubed it up 4 times with about 8 drops each time. I let it sit for 2.5 days. I put it back on the ground and left the inspection cover off. I fired it up. Let it warm up and took it for a drive. NO NOISE!!!Chuck Lutz wrote:Twenty years of long hot summers may cause a flywheel bushing to lose some of its' ability to lubricate the bushing and the main gear.

I am not 100% sure what it was, linkage or oil, but at this rate I don't care.
I drove it for 40 minutes and it did not do it once!
I appreciate the guidance! One thing I love about the jeep world is everyone is willing to help each other.
Jeep ON!

Re: Clutch Thrust Bearing
Does anyone know what the bearing number is so that I can order a new one before taking the old one out?
Thanks in advance

Re: Clutch Thrust Bearing
It's easy to find on Ron's parts site; 635529 https://www.vintagejeeps.com/search.asp ... term=throw
A-2013 is the actual Aetna brand part number.

Re: Clutch Thrust Bearing
Where are you going to get your clutch from? or going to reuse the old one? fork may have wear on it along with the throw out bearing carrier ears.
