pulley

[b-80boz 0]

I bought an air comp. with I THINK IS A 12 HORSE MAGNUM ON IT I`m wanting to put this on an older sears suburban. It has a pulley on it that I`m not sure how it will come off. IT HAS 3 BOLTS ON THE FACE of it I took those out but I still can`t get it to budge .Is there something else I need to do or should I just try a puller and a mallet I cant find any set screws on it just wondering if anyone has a trick up their sleeve on getting this off. Any help would be appreciated thanks. :omg:

it sounds like you have a "split taper bushing"

type of sheave (pully) if you do, take a look at the holes

around the bushing 1/2 will be threded 1/2 will be thru

holes.

Take the bolts out of the thru holes and put them in

the threded holes, as you thighten them up evenley

it will work as a puller and separate the two parts.

if this is not what you have please post a pix.

Formally know as a "quick detachable" or "QD" bushing.
