FD Alt on S4 FC Pulley Problem (Mazdatrix Pulley)
Hey guys,
I'm having some issues mounting my new Mazdatrix pulley to my 93-95 FD Alternator. I have removed the OEM spacer on the FD alternator because the pulley comes pre-spaced from Mazdatrix. I then install the pulley in this order Pulley, Washer, Nut. I then proceed to torque down the nut holding the pulley and washer via impact gun. But, here's the problem, when torqued down the pulley makes contact with the alternator housing and won't spin freely. It locks up. I had to use a pulley puller to remove the pulley. Am I missing something or do I have a defective pulley with the wrong size spacer? Help me out.
Thanks

get a bigger spacer.I had this problem when going to an FD alt on an s4.
luckily I had a spare Fd alt and used the inside spacer from the old one with the new alternator and it brought the pulley out far enough.
That spacer was thicker than the original outside one.
I ran into the same problem with the "Higgi pulley" too.You know,the one with the Rotor design on the Front?...that one.
edit:..Is the pulley meant for an Fd alternator?.

The mazdatrix s4 pulley for FD alt has a built in spacer. I have the same unit. I had to sand the annodize off it to get it to slide onto the shaft. Fitment looks ok, but I haven't tightened it. My suggestion would be to use lock thread and not tighten it so much? Take it to a grinder and remove a small bit of material where it is coming in contact?
I'd call mazdatrix first. Their telephone support has always been more than pleasant for me.

I noticed with those pulleys(have not seen Mazdatrix though) is that sometimes it'll fit perfect or sometimes it'll require a washer/spacer under the pulley. I've had Japan2LA and also the higgi one and both ran into the same issues where it would fit on one FD alt but not another. I'm assuming it has something to do with the FD alt housing itself but in any case I just used a washer and all is fine.

I don't remember which one. The oil cooler/hose sealing washer or the front cover/hose sealing washer seemed a great fit on my FD alternator as a pulley spacer.
