pilot bearings?

[vashxj]

Hey I cant seem to find a straight answer on this, I cant find it in faqs or searching. So do all 4.0/4.2 cranks have the same pilot bearing hole? I know all the input shafts on the trans side may be different but im swapping my auto to a ax-15 and I have the 4cw long noose crank. If I had to guess I would say they are, just wondering if anyone has run into this

Apparently not?, the clutch kit I got for my Wrangler came with two pilot bearings?, I'm not going to stuff one in the crank until I get the thing apart to see what I really need?

are both the outer diameters of those bearings the same?

Here's a straight answer for you:

'92-'99 AX15 and NVG3550: OEM pilot bearing 53009180AB for '87-'91 engine or stroker

I'm using the pilot bearing 53009180AB.

thanks I just wasnt sure it the back of the crank was the same, haven't taken it apart yet and probably wont until its atleast 40-50 degrees out

NO!

Prob the smaller one

So, we are having this issue with our stroker. The pilot bearing for the 99 transmission does not fit the 4.2 crank we installed. The pilot bearing for the 4.2 crank has a smaller inside diameter for the older transmission.

Does the 53009180AB pilot bearing fix this issue?

Any suggestion is greatly appreciated.
