I am changing my head back to stck for a few weeks. I got a head off of ebay but it didnt have the stock pulleys. I went to the ford dealer and the one they called for the blot was too big for the hole on the head. Could ford have changed the pulley from year to year? what else could be the problem. THanks

Zetec engine right?
Are you sure you have the right pulley?
There is a tensioner pulley (part# F8CZ-6K254-AA),
a 47mm idler pulley with a staked-on bolt
(part# XS4Z-6M250-BA) and lastly a 60mm idler pulley
(old part# YS4Z-6M250-AA or newer part# YS7Z-6M250-BA).
For regular Focus Zetec engines, the pulley parts would be all the same from 2000-2003.
