Evening Chaps,

I'm currently working through my supercharger build on the bench, and I have found tonight that the poly v alternator pulley that I bought as part of the 3 pulley set, is for a larger shaft size (17mm) than my old Lucas alternator that was fitted with the std v belt pulley.
Do I have the wrong pulley? Does the MPI alternator use a larger diameter shaft?

Thanks in advance

Stu

The MPi pulley I have is 16.5mm and fits altenator shaft perfectly.

Remember to check alignment of the pulleys; I had to make/rework a spacer.

Dazed and Confused....
