Clutch pilot bearing problems

[W Barrow]

Hoping someone has been here and can help. I am installing a 93 4.0 ho into a 90 renix with a 5spd ax15 and looking at the measurements on the pilot bearing the 93 measures inside diameter .75 , outside diameter 1.81, width .719 and the 90 measures inside diameter .5934, outside diameter 1.055, width .719
I know the outside is different because of the crankshaft and is not a problem and the width difference does no worry me but the inside diameter is the problem. because the input shaft on the trans is to small for the 93 bearing which is the one i need to fit the crank. I know i can have a bushing made for the crank but i was hoping someone may know of a bearing that is the right size inside and out.

I don't know of one specifically. You might check a decent auto parts store. Most of them will not be able to help you since they work off data bases. But if you can find one with some old timers behind the counter you might find something

From the Tech Specs page of my performance website:

Pilot Bearings

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:
