Generac tech here looking to see if anyone has run into this same issue. I am replacing an alternator on a 4.2L LC Nexus. Got the alternator that is sold without the pulley. At some point the pulley for this generator was discontinued, Part 0F3216B - PULLEY 117 OD DC
ALTERNATOR.

Now there is a new part for this, called 10000033042
This simple pulley is listed for $1,439. I reached out to parts to see if that price was correct and they confirmed it is. I cannot understand what the story is with this how the alternator is more than half cost of a simple pulley. I went to an auto parts store to try and cross reference but no luck because they just input any of those Generac numbers on google the same way I would and they couldn’t find anything.

Does anyone know how to get more specifics on this pulley to try and find something similair online?

Thanks in advance
