automatic/pilot bearing

[jeepthing07]

I am swaping a 4.0 out of a manual trans with the pilot bearing into a XJ with a automatic. The torque converter has a nub coming out of the center and i am wondering if i have to remove the pilot bearing and spacer to get the AW4's torque converter to mate up to the 4.0 with the bearing still in the crank or if it will fit even with the bearing in there?

What year? I got a pilot bearing for an 88 Comanche BA10 5speed that I can test fit to an 90 AW4. Are you swapping out a BA10 for the AW4 and what years? :chillin: :brows:

Ok, I see, the 4.0 had a manual tranny and still has the pilot bearing.

Well the automatic don't use a pilot bearing but it has a stickout on the converter that looks like it might end up where the bearing is at now so i don't know if i need to pull it out or not

we swapped in a 4.0 to my bro's truck that came from a manual and we had to pull the bearing but didnt have to put one on (out of a BA10 truck into an AW4 truck)

we rented a pilot bearing puller from the auto parts store... you pay deposit, pull bearing... return tool, they give you back ALL your money 8)

Yep, I found my old pilot bearing and it is exactly the same diameter as the nub on the converter. You have to remove the pilot bearing. Nothing goes in the crank hole to replace the old bearing. The nub should just fit right right in there.
