Hey guys, another easy question for anyone whose done this before.

Im in the process of changing a 4.0 liter from a 99 cherokee with an auto tranny in it, to work in my 99 wrangler with a manual trans. My front end (belt driven end) is squared away, all peaches there, been there done that.

I am concerned about the difference between my old engines crankshaft end looking different, almost as if it has a larger bushing or spacer around the bearing, to hold the pilot bearing inside of it. I have no idea if Im seeing things, because of the engine rack being in the way of my old one, or if I actually am missing a bushing or something.

you can clearly see a difference, as my new one (not on the engine rack, it has the flywheel on it.) has nothing inside of that crankshaft boring where the bearing is supposed to go, and if I go putting it all the way back in that smaller hole, it looks like it will be entirely too far back for the main shaft to actually slide into.

My kit came with a bushing and a bearing... as seen in the pic. My initial thought was that the bushing was used to drive the pilot bearing into the hole, but I don't think thats the case... what is that thing? ( sorry guys, Clutch kit came with an AWESOME installation manual. So awesome in fact it wasn't even in the box.)

I do apologize for the old engine having such a poor view, that was the only way I could get a good view of it with out unbolting it and pulling it away from the rack.

What am I missing? If anything???

You are missing the steel bushing adapter that fits in the large hole in the end of the crank that the pilot roller bearing presses into.

Do yourself a favor when you install the bushing and just press it in flush to the outer lip in the crank. If you bury it all the way, it makes it very hard to get a puller on it later.

It will look like this when you are done.

 

Ok... Im really stumped and wondering why my kit didn't come with it. oh well. I really don't wanna get that thing out from my old one, are they fairly cheap and easily acquirable?

 

and what about that smaller brass colored bushing that it came with? where does that go?

It looks as though from your pic you have it in behind the pilot bearing

 

I can't find these things anywhere on the internet. very few people even acknowledge they even exist. Im gonna have to get this stupid thing out of my old engine.... will a grease pack method work? That adapter
is pushed way back in there from the factory.

Type in Jeep TJ pilot bearing adapter.

Research that part number to see if it fits.

 

I found one!!! National needle sells a bearing and sleeve combo, and my oreilly has it in stock! got it ready for in store pick up tomorrow!

I don't like the look of that bearing though, gonna try and get it out of there and get my timken in there.

 

dimensions:
Bore=0.7518", Outer Diameter=1.8161", Width=0.565"

 

the bearing outer diameter itself is 1 inch... looks like that bushing adds on .81" to the fitment. sounds about right to me. Not with the jeep anymore, but I think that will work.

 

Any one have any idea what that little brass/copper colored bushing is? or where it goes? my only thought is that it slides in behind that bushing and bearing...

Its slightly smaller than the pilot bearing its self in diameter. I originally thought this was used to drive in that pilot bearing am I right?

 

It is a pilot bushing for a different application.

 

I dunno, it's not used with the pilot bearing in a TJ. Your guess is that it's used to seat the bearing is as good of an assumption as any.

 

The brass one is a pilot bushing. Was used in many american cars and trucks into the 80's or so before they started using an actual bearing

 

Success! Thanks guys!

 

Nice job! :tea:

 

Does the bearing adapter as well as the bearing come out of the end of the crank when converting from an NV3550 to 32HR? If so will a standard puller pull it?

Thanks.

 

Yes, no. You need a special puller for the bearing and adapter.
