anyone here rebuilt a NP231 before?

[Tripwire]

I just simply dont want to replace the chain and seals, i have had this rig 30 years and i want it to last 20 more

what else besides the bearing kit? im not interested in beefier parts or output shaft mods

If you get a master rebuild kit and the chain that should replace pretty much any wear item in the case.

where do i get a inclusive kit? i have been looking for one, but only find seal sets, bearing sets, gears, and chain individually

This is where I was planning to get the stuff for my NP241:

http://www.jbconversions.com/products/np231j/rebuild.php

That's the master kit for the baby Jeep NP231, the chain is also listed on that page.

National Drivetrain might be another place, I don't see a full kit listed directly but I'm sure a quick phone call could get you the info you need:

I'm sure there are others as well. Maybe Novak and/or Advance Adapters? I got my D300 kit from Novak, and it had everything.

Edit: master kit from Novak: https://www.novak-adapt.com/catalog/...s/np-231-parts

Trip, you may get more response on https://www.naxja.org/forum/ They focus on XJ's

I have rebuilt two. Just for the piece of mind, because they are not very expensive, I replaced the oil pumps on both. I considered it cheap insurance.
I actually bought my rebuild kits off ebay. They came with koyo and nachi bearings, which is what came in them from the factory.

Trip, haven't done a 231 but have done a 208 and a D20 with Novak's parts/kits. No idea of orig manufacturing source... but it was quality stuff. Everything fit/went together as it should and held up well. I would use them again.

It has been several years ago, but I think it was trans parts warehouse.

They also have a ebay store under the same name. You might email them to ask what bearings they use, as you never know, things can change over the years. KOYO and NACHI are the bearings I pulled out of every factory NP231 I have torn down, and it was also what I put back in them.

Trip- might give Randy's R&P a call. They might get into kits and would be more or less local for you,

I used to get mine from SeaTac Parts warehouse by the airport.
