Hi All,

Just ordered a new Vacuum pump to replace the previous one which seized on my 1990 F250/7.3 IDI. ($102 from Kragens). from the pictures on their website, it looks like the new one comes without pulley. I took a look at my old one, but can't see exactly how to remove the pulley. Does it need a puller to remove, and to be pressed onto the new pump?

There is a threaded hole in the front of the shaft on the old pump - I'm sure that must be something to do with removing/replacing the pulley, but I'm not sure what...

Thanks,
Chris.
