For the life of me I don't get how to put this thing back on?

Im affraid to just grab a hammer and start whacking away at the damn thing but no kit regardless of who makes it apears that it would work for putting this thing back on.

Anyone have some ideas for me as to how to get my new pully on?

 

Whack it with a hammer. that is how I do it. You will not hurt it and then put your bolt in.

 

I beat the **** out of mine with a hammer till it went back on, I'd recomend using a block of wood to cushion the pully while you hammer on itif your worried about chipping it.
