Pilot bearing issue

[Aidenmoreno3]

hey guys!

 

I recently installed a luk clutch kit into my jeep as the internal slave cylinder had failed and was leaking clutch fluid causing slippage and making it hard to go into gear. 

 

I have a 1992 comanche that had a 1995 TJ 4.0 high output and ax15 swapped into it. when we did the clutch job we noticed the pilot bearing sat in the crankshaft very loose but didn't think anything of it at the time

 

When we test drove the jeep there was a high pitch "whirring" noise and the clutch petal was vibrating which upon further research was said to be the pilot bearing. I truly believe this is the issue as the car shifts and drives fine until the noise and vibration happen. 

 

Here are the three pilot bearings I know of in the picture attachments:

 

My question is, is the problem my input shaft diameter for the ax15, or do i need the pilot bearing with the bushing? The picture labeled pb2 is the one that comes with the luk clutch kit that slid in a little too easy and is currently installed in my comanche. Any help would be appreciated! I wanna drive my truck again especially since the new clutch and fully filled trans drive so much better than before.

doesn't advance adapters or Novak sell the appropriate adapter bearing?

Yeah they do Pete. You need a bushing that fits snugly over your input shaft and has a press fit, (hammer action) in your crank bore. Should not be able to put it in and out by hand.
