I've got the trans out of my 2a. In the 500 fti drove the jeep before disassembly the clutch seems fine.  so does the bearing actually.  but I'm considering replacing both while I have trans out. ( and body access) omix has a kit on sale for 170 for clutch pressure plate bearing and fork.  what do you guys think I'll regret more. Buying a clutch I don't really need or not replacing it when it's easy to get to?

Replace it! I didn't and three months later I had to tear it down for a bad throw out bearing and pilot bushing. Just think of it as the time is to do it all again or 170 dollars.

Regret? Buying Omix.
Purchase quality parts and do the work while it's already apart.

I say don't replace it, if you have not made that mistake before, you need to learn that lesson yourself! Big smile You can never have enough practice taking a motor or transmission in and out.....Be sure to have the clutch disk facing the correct way! A lesson I learned the fun way....

Generally the rule of thumb is to replace all of the parts while you are in there but considering the quality of Omix parts I would inspect what you have now and make your own call.

Haha you have all just echoed my exact thoughts on the problem. I'll see what napa has then decide.  bearin fb is getting replaced no matter what. The clutch disk however looks clean and seems fine. I don't know original thickness but looks like plenty of material left.

These are pretty simple engines to pull out, so going backing in is just a good weekend in the garage Smile.  I have replaced everything in the past with NOS parts, only to have to pull it apart again because the NOS throughout bearing began to make a whirring sound after less than hundred miles. 

If you don't drive it a bunch and have replaced the parts in the past - check the pilot bushing, examine the face of the fly wheel and pressure plate, replace the clutch and throughout bearing.

Is see kits to rebuild the pressure plate which is something else that can be done if the face of the pressure plate is good.

So many opportunities for good wrenching on these old Jeeps!

I would examine the clutch disc (I can measure the thickness of a new one for you if you'd like), the pressure plate and the flywheel for wear, burns, and scores, and determine whether they are re-usable. I hope you marked the position of the pressure plate on the flywheel before you took it off. If you don't get it back on clocked the same way, it might chatter. The pilot bushing is cheap and easy, so replace it, and the throwout bearing is hard to judge, so replace it. If you do replace the pressure plate and disc, make sure you have the flywheel surfaced, or again, you're asking for a chatter.  BW

Edit: And I agree with RICKG about the regret part.  BW

I would add...  Don't assume the brand new Throw-Out bearing has been greased up real nice from the factory.  Nothing more aggravating than to have to take it back apart just to grease a brand new squeally bearing.

If you only want to do this to prevent future problems... DO NOT USE OMIX PARTS.

I bought a clutch kit from Rockauto.com for a good price.  The throwout bearing is marked "Made in USA".  No OMIX.
There's a reason it's called Ol' Unreliable

I'll look into rock auto. Napa wasn't able to find one.  the bearing will definitely be replaced. The clutch disk and pressure plate are still undecided. They look fine but 70 year old parts sometimes brake.

Regret? Buying Omix.
Purchase quality parts and do the work while it's already apart.


X3 on the regret.

While it is possible that those clutch parts are 70 Years old, I seriously doubt that they have not been replaced in those 70 years.

I would look at the pilot bushing, the disc & pressure plate. I would also replace the throw out bearing. remember to grease the new one. Also grease the pilot bushing.

 Oh, in case I forgot, X3 on the regret. Buy good quality parts.
