I can't see them going in any other way ... but then it spat out the last set. :dunno
-
Yup. That's the way they go.
-
Is it possible the last set of nuts was defective or maybe really old old stock? If you saved any of the pieces see if they're crumbly, maybe at least get some money back from wherever you got them.

Euro Motoelectrics. They looked new and the rubber did not seem to be old. They were a lot tighter going in so maybe they are reproductions, and a tad oversize. They were only $12.95USD for the set of 3.
When I ordered from the local BMW dealer I ordered 2 sets ... I thought ... for $46CDN. When I went to pick them up they had only had 2 nuts, "sorry Sir they don't come in sets", so I had to order another nut. $61CDN (+ tax) vs 12.95USD is whack ...

Ed obviously they don't know much about Bricks or can't read the parts book. I hope your nutz are good and don't crumble. ( I feel really strange saying that never thought I'd be discussing another guys nutz ) :hehehe
Regards a slightly weirded our Martin.

I believe what might happen during installation of the alternator is a blade of the drive dog will contact the edge of one of the cushions instead of passing between the two cushions and will lever the cushion out of position. That creates slack and then the grinding begins. Lubricatiing the cushions where the blade passes between them is recommended by some, as is using a dab of sealant beneath them to hold them in position that creates as much gap as possible—which won't be much—during careful alignment.

They was lubed ...
-
I wonder if they were manufactured with EPDM(sorry, I apologize for not knowing what it stands for) rubber. If they were, you need to be very careful about what you use to lubricate them as EPDM breaks down with some lubricants.
I always assemble my alternator drive with with generous amounts of liquid soap.

Apology accepted. Google still works in the PRV.

When I installed mine they were a loose fit that required gluing them into the cup. I then put silicone lube in the spaces that the drive vanes went into.

Yes, as stated here, you need to play with them more and use lube before insertion.. That should set you straight? :hehehe

Don't forget! Use high vacuum lube for maximum effect.
-
Some sort of glue (I used silicone / gasket in a tube) to fix them into the cup but also wedge some spacers in between the rubbers (eg 3-5 mm hard board/ plywood, masonite).
Let it dry.
Place a mark on the outer edge of the cup (holding the rubbers) to help with alignment on re-installation.
I fried my rubbers on first attempt.
Second time (as above) very easy
Everything's so logical in hindsight
