OK so I am currently swapping a 4.0 that came from an auto to my XJ which has an ax-15. I got a new clutch kit and went to install it on the new engine with the flywheel but it of course doesn't have a pilot bearing.
The clutch kit came with a new pilot bearing but not that bushing thing that goes around it. So I guess i need to order the bushing, put the pilot bearing in it and then put it on the engine is this correct?
Unless I'm missing something (which is vaguely possible,) you would have
either a bushing
or a bearing to guide the input shaft pilot -
not both.
The pilot bore size may be different between the AW4 and the AX-15 (especially since the AX-15 is known to use two different pilot sizes - ~5/8" and ~7/8") and that may complicate ordering a bushing/bearing for use here. Have you a set of calipers to take an accurate measurement? Once you know the ID and OD of the bearing/bushing you need, you can probably pillage through a Timken, NSK, or BCA bearing dimension catalogue and find what you need.
Once you do, please post the data you collected and the bushing/bearing you ordered so that others can be helped (since, as you can see from the post above, your problem is not unique.)
Conversely, if you can obtain measurements that are accurate, you can post them and one of us can help locate the thing for you. NB: If you don't know how to use precision measuring tools, I suggest taking three separate measurements and posting them all - which will let us figure out an average (or, more typically, you end up with two identical measurements and a "flyer" under the Law of Averages,) and we can interpret those instead.
