Does the power steering pulley have a key or is the shaft tapered for a press fit? I need to remove my pulley to replace a rounded off mounting bolt. I loosened the pulley nut by holding the pulley with an oil filter set of pliers a little bit now the shaft just spins in the pulley and the shaft has no resistance to take the nut off. The shaft has a hole in the middle for a Puller but is not machined for an Allen wrench like an alternator. Thanks for your help.

That's what I get for speed reading the original post. Yup, wrong shaft/pulley. I have not had issue with the power steering pump pulleys on either my Series III or IV but will check for that factory nut you mention. Thanks.

You had a crankshaft pulley get loose, ruining the snout on your crankshaft. This gentleman is having issues with the power steering pumps shaft/pulley.

Been there, done that, ruined the crank and ended up doing a full out of frame overhaul and getting a good used crank out of another D17 parts engine. Mike

Doesn't sound too good to me. Jam a couple of screwdrivers between the pulley and pump to put it under pressure. Hit the nut with an impact wrench. I think your pulley and shaft are junk.

There is a key. Don't remember if it a small half-moon (I think it is) or a small straight key. Do yourself a favor and throw away the factory nylock nut and replace it with a regular 1/2" NF hex nut and LOCTITE it and get it pretty tight while holding the pulley. That cheap nut was famous for coming loose and ruining the pulley and shaft when they got loose.

Will I have to take the pump apart to hold the shaft to remove the nut? It just spins inside the pulley now since I loosened the nut a fraction. Thanks for your help!!

Today's Featured Article - Sunday Drives - by Cowboy. Summer was finally upon us here in Northern Maine.
