These are no longer available from Mazda, so we have started making them.

OEM pulley shown for reference only, you will receive the black aluminum pulley that we make.

There is another pulley for this application that has 3 bolt holes and connects to a hub, this pulley will work in its place you just need to remove your hub and this will slide onto the keyed shaft.

Mazda doesnt list a woodruff key for this pulley, but the oil pump woodruff key fits in the pulley groove great, dont have a shaft here to test it on, but you could always sand it down to fit if needed.
