M20 Alternator -- Fan/pulley parts order

[Ali//325i]

My alternator on my cabby (10/87 build 325i convertible) went out, so I bought a new replacement from autozone and ripped the old one out.

I ripped the fan assembly off the old alternator and forgot the order of the parts

I tried my best using the diagram on RealOEM ( http://realoem.com/bmw/showparts.do?...21&hg=12&fg=22 ) to put it back together but when i got everything on the car and started it it makes this awful metal on metal sound.

My new alternator came with the following parts:

#20 - lock nut
#21 - crush washer
and the alternator fully assembled

But I had to reuse #19 (the pulley, which isn't really a pulley but 2 separate half circle pieces that create a pulley) and #18 the fan blade.

I also had 3 different washers from my old alternator. which don't seem to show up on the RealOEM diagram. I tried my best to find where each went but I think the order that i put them back in is the issue.

Does anyone have an e30 alternator out of the car that could take a picture of all the pieces in the correct order? I really don't want to take the car into the shop to have them do a full replacement, right after I did all of it.

Any help is greatly appreciated. Thanks!

realoem diagram should be adequate to reassemble. did you re-install the plastic bushing at the end of the shaft ? also, if you don't have the bracket on correctly the fins will brush against it.
