I believe it is the old style. It has a slot (key?). It should just slide on and then one nut to hold it in place from the looks of it. It does not have a place for a bolt to go and press the pulley in.Originally posted by PDQUICK:
Do you have the early pump with a key and a nut? if you do, then you can gently tap the pully onto the shaft. It won't take much persuasion.
If you have a press on style, dont hit your power steering pump with a hammer!!!!! This can severely damage the pump.
The end of the pump shaft is threaded for a 3/8 coarse bolt. Get yourself a hard 3/8 bolt with about 2 1/2" of threads on it, as well as a couple of good nuts and some different diameter washers. Thread the nut all the way on to the bolt, throw on the washers and the pulley and then thread the bolt into the pump shaft. Use the nut to press the pulley on to the shaft without damaging any parts
