My 2.0 Zetec has a Ford alternator using a multi-vee belt/pulley system.

Seen that a Lucas ACR alternator are more common and easier to repair/replace than the ford.

But as I have multi-vee belt and pulleys, will the ford alternator pulley fit the lucas alternator.

If not any clues where I might find one or engine similar in size to fit.

The Lucas A127 (aka Lucas Magneti Marelli A127) alternator has the same mountings and connections as the Lucas ACR but in Rover comes with a poly-vee pulley --- mainly found on late 80's early 90's Rover K series.
This a very easy alternator to overhaul -- brush and regulator pack are external to the casing and changed with 3 screws.

Unlike the ACR the A127 has a keyless pulley so the pulley cant be swapped to an ACR

I use the Lucas alternator and you can get v pulleys on eBay virtually any size you like, for both 15&17mm shafts which are the two sizes the Lucas alternators use. I will try find the link to the eBay seller
