in the middle of my engine swap. now, i'm not sure what engine came out of the YJ, but i'm pretty sure its actually a 91 engine/tranny. the pilot bushing in there is one of these guys https://www.quadratec.com/products/52008_00.htm
picked one up at Canadian tire today but it just wouldn't go. am i missing something? the engine came out of fugs 96 XJ. am i missing something? the pilot bearing above fits on the transmission just fine, but i can't hammer it into the crank; its a hair to big. think it was just defective? (i also have a pilot bearing for a 96XJ but it doesn't fit.)
any ideas are greatly appreciated.
cheers
-
Even tried putting the pilot bearing in the freezer and heating up the crank. would not go in.
-
I vote for sawsall... just make the hole a little bigger ;)
Maybe some KY?
-
right about now i'm debating parting it out.
-
where's the old pilot bearing for the engine? might be able to swap the little inner bearing with the outer casing. it's pretty much what I had to do.
-
You hitting it with a hammer? or something like a socket over it to keep it straight?
more info...
The 5-speed manual transmission is the light-duty Peugeot BA10/5 in the '87-'89.5 4.0 XJ, the medium duty Aisin-Warner AX15 in the '89.5-'99 4.0 XJ, and the medium-duty New Venture Gear NVG3550 in the '00-'01 4.0 XJ. When carrying out engine swaps (either another 4.0 or a stroker), selection of the correct pilot bearing can be a headache. The details below will make choosing a pilot bearing simple:
'87-'89.5 BA10/5:
OEM pilot bearing 33004041 for '87-'91 4.0 engine
Advance Adapters pilot bushing 716120 for '92-'04 4.0 engine
*Upgrade transmission to AX15 or NVG3550 for stroker engine swap*
'89.5-'91 AX15:
OEM pilot bearing 33004041 for '87-'91 4.0 engine or stroker
Advance Adapters pilot bushing 716120 for '92-'04 4.0 engine
'92-'99 AX15 and NVG3550:
OEM pilot bearing 53009180AB for '87-'91 engine or stroker
OEM pilot bearing 53009180AB or 53009181 for '92-'04 4.0 engine.

That's funny, I was just about to post this info. I found it on Greatlakes4x4.com. It sounds like you need A.A. 716120 bushing, unless I'm mistaken. $23.91 on their website.

apparently i'm not the only one with this problem.
i'm about to light my jeep on fire.
-
now that i see the pic i know what you've got. i had this issues long time ago. i took the pilot bearing to a machine shop and they shaved it down a girls-junk-hair thickness. and it fit fine.
-
A couple of years ago I swapped an AX15 from a 98 ? TJ into my 88 YJ which happens to have a 258 crank from a 70? something ? CJ and a 93 4.0 block.
A pilot bearing does not exist for the application described above.
What do I do in situations like this ?
I make one , a bushing does the job just fine .
In your situation , you may be able to buy one , measure the bore in the end of the crank ( if it's still round ) , measure the pilot shaft
Report back with measurements

Jeff, Eric
thats the plan......... dropping a bearing off at Jamey's tomorrow to take a hair off.
thanks all i'll update when done
-
I didnt read all of it, but the pilot bushing changed in 93-94 john. Get the one specific to your year of crank and you will be good.
Nevermind, i see serge nailed it, and the change was 92-93.
Goodluck
-
What's the status of your engine swap buddy? You never did post an update.
-
yeah! wtf? did that thermostat housing work out for ya? and wheres my new to me housing??? lol!
-
Stat housing worked out fine... Tiny is in Cuba for the week.... smoking a big, long, dark......
cigar. You sick bastards.
-
i'll update it tonight when i get back into the garage. i was busy 'product testing' rum and cigars in the dominican ;)
-
well everythings back together now and the jeep is running mint. i can't get over the power i have back. i guess when you have all 6 cylinders firing it works well :)
i will admit it was a lot of work to which i owe a bunch of people a thankyou for; big thanks to Jamey for taking the time to make a pilot bearing work for me and just helpful insight.
thanks to heeps for the tstat and idea for the guage. saved me a lot of headache and work. tstat works well! and big thanks to Seanner, Trevor and good ole' Grease Nipple (my neighbour) and the pook for their help. made it a lot easier (mostly cause i'm lazy ;) ) and thanks Fug for the engine! and even had it pulled before i got there!
can't wait to go wheelin next week. woop woop
-
Thats awesome! Am so glad it worked out well... I figure you'll get a good many km's out of that engine... it ran like a top before it was pulled.
-
good job duder! go wheeling! i want the empty seat sometime if i can make it. ill bring my camera!
