Oddball ax15 question

[Oizarod115]

:huh???: I have in my possession an unknown year internal slaw ax15 from a yj that was behind a 4.2.

 

I intend on putting this behind a 97 4.0L and was wondering if anyone knows how I can determine up front what pilot bushig will fit or tell me what the measurements are so I can check it with a micrometer.

 

Thanks all,

Nick

If you have a micrometer... why not just check the tip of the input shaft on your trans?

well i will, just wondering if anyone knows what the normal ax15 pilot bushing measurements are

1/2", is what the 87-90 are. 91+ should be .750 or 3/4"

yep yep...I just put a 93 trans into a 90, so I had to make a pilot that measured 3/4" ID, with the proper 1 and 1/16" OD.

 

 

the OD is bigger in 91, I think.

i'll get the measurement on that tomorrow and put it in this thread so it'll come up in searches and all be in one spot maybe ;)

 

i have known year motors lying around just don't know the year on that tranny.
