ftpiercecracker1 Posted February 19, 2013 Share Posted February 19, 2013 Just pulled it out today, odometer was a little confusing, it was half way between the one and two in the hundreds of thousands, so either it has 113K on it :yes: or it has 213K on it :ack: I am hoping for the former. As the topic says it came from a 93 ZJ, aw4 auto, 4x4. I am about 98% sure the motor itself is sound, all the fluids checked out. Coolant was pretty much new vibrant green, oil showed zero signs of contamination, albeit was black, had no signs of catastrophic overheating, and the engine in general looked pretty good and clean, no leaks from head, front main, or rear main. It also had a new water pump and starter. The only thing that i saw that concerned me, was when we pulled the exhaust and intake man there was a substantial amount of carbon build up in the exhaust ports. Do you guys have any recommendations as to basic things i should do before dropping it in my MJ? I am just about certain there will be no problems using this for my comanche, the only things I can think of are the Pilot bushing and the flywheel. Both of which i have. I also have all the Renix and HO acceories, intakes, exhaust mans as well. I suppose the point of this thread was to ask you guys just to be doubly sure there is nothing i have missed. thanks fellas ftpiercecracker Link to comment Share on other sites More sharing options...

ftpiercecracker1 Posted February 20, 2013 Author Share Posted February 20, 2013 Ya tell me about it, :dunce: I talked to my local auto parts store about the whole pilot bearing/bushing deal and they said that maunals have a pilot bearing. What excatly is the deal with the pilot bearing/bushing? What needs what? Bearing or bushing? Can i reuse my old one or should i get a new one?

cruiser54 Posted February 20, 2013 Share Posted February 20, 2013 Manual trans now? ZJ motor come from a manual trans vehicle? Sometimes as far as pilots go, the nomenclature of bushing and bearing are interchanged. Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted February 20, 2013 Author Share Posted February 20, 2013 No no no, the motor did come from an auto, 93, ZJ, but my comanche has an ax-15, which i will be keeping. Link to comment Share on other sites More sharing options...

You need a pilot bushing/bearing then. Not my area of expertise as far as years/interchangeability though. Not a big deal. you'll get the info you need soon enough.

Geonovast Posted February 20, 2013 Share Posted February 20, 2013 What year is your AX-15 from? Original in your 1990? If it's a 92+ AX-15, you'll need the bushing/bearing for a 92+ XJ with a 4.0. If it's an 89-91, I'm not sure. I know the newer trans behind the older 4.0 gets the 74 CJ 304 bearing, but not sure about the older trans behind a newer 4.0.

The inside of the door says 89, I have the original block that was mated to the transmission sooo. . . Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted February 27, 2013 Author Share Posted February 27, 2013 A little update and info, a pilot bearing for a 93 zj will not work with an 89 ax-15, ID of the bearing is too large. But neither will the pilot bearing for an 89 4.0 work in a 93 zj crank, the OD is too big. Link to comment Share on other sites More sharing options...
Geonovast Posted February 27, 2013 Share Posted February 27, 2013 Yup, makes sense. If there is one that works, it'll be from something obscure. You may have to find one with the correct OD, and an ID that's too small(might be difficult though), and have it drilled out. Or find a local machine shop and see how much it would cost to just have one made. Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted February 28, 2013 Author Share Posted February 28, 2013 The bearing that is meant for the 89 is very close, with a little encouragement from the grinder I know I can get it to work. I was just hoping I could find a bearing that would work without modifying. Link to comment Share on other sites More sharing options...

If I found out the ID and OD of the original bearing I could cross reference them against other bearings dimensions, the problem is that the auto parts stores do not list said dimensions. I would have to order every bearing that 'looked' like it might work and then measure it once it came in, which could take weeks, if they even let me do such a thing.

cruiser54 Posted February 28, 2013 Share Posted February 28, 2013 YOu need to go to a real parts store. Or a clutch rebuilding place. Bearing supply place. somewhere they have real seasoned parts guys and not just keyboard punching putzes. Link to comment Share on other sites More sharing options...
Biotex Posted February 28, 2013 Share Posted February 28, 2013 A few years ago when I was into Scouts, I bought up the NOS inventory from a once dealership where the parts were stored in a wharehouse for a few decades. Among those parts was a box of assorted pilot bushings. If you could give me the sizes, I would be happy to see if I have one that will fit your needs. Here is what I have learned about the difference between bearing/bushing. Bronze pilot bushings should be soaked in oil overnight before installation. They seem to work better in dusty conditions, but that is only what I have read, not actual experience. IMO, bushings wear out faster than bearings.

The current bearing, for the 89, has the right ID (.591) but the wrong OD (1.055) It needs to lose the .055 off of the OD. Link to comment Share on other sites More sharing options...

Biotex Posted March 1, 2013 Share Posted March 1, 2013 The closest I have is a bronze bushing with the correct ID .588, but 1.092 OD. It is yours if you want it, but will need a lathe to turn the OD down. On 2/28/2013 at 3:04 PM, ftpiercecracker1 said: Thanks for the offer, I will see what i can do.

I spent 45min at NAPA with their senior staff and could not come up with anything. The closest one would have been from a 92/93 cherokee with a 1" OD and .75 ID, although I am not sure if the .159 would have been to much slop to make it a feasible solution. Either way, I am actually glad it happened, its just one more thing under my belt of jeep knowledge.
