power steering pump pulley stuck

[Ron]

The engine is out of my car and I'd like to replace the shaft seal on the power steering pump while it is also out.  I've removed the pulley nut, and installed a puller on the groves of the pulley (3 jaw puller).  The pulley belt groove walls are bending, it is so tight.  Am I missing something?  I'm thinking I need to apply heat.  Ideas?

Hello Ron, If you continue to pull on the outside of the pulley you will render it useless.Obtain a bearing splitter adaptor for your puller and locate it around the groove that is machined in the pulley hub.

Hello,

After tightening up the puller (stop before things bed), give the bolt end of the puller a good smack with a pig hammer. The shock will usually pop the pulley off.

Hi All, just to give an end result, I ran out of time deal with the pulley issue until this week.  Using the hints from your replies, I looked for ways to attach the puller to the pulley hub as suggested.  There were no attaching points, like I see on my diesel's pulley.  So I again used the puller with the belt grooves until I felt I would bend the pulley.  Tapping the puller did not free it.  Next I applied some heat from a propane torch, and the pulley slowly came off with tapping, tighten, and heat repeated.

Next I looked at the key.  It was too thin for the pulley keyway, but just right for the pulley keyway.  This is the wrong pulley!  I applied the PS pump bracket to the engine, hung the pump, and slid on the pulley. The grooves don't align.  So I have to find the correct pulley.

It is amazing what people will do to a car over the years.  I wonder what the PO was thinking?

PS I forgot to mention, the pulley and the key were glued on, using J-B Weld.  I found some of the stuff while cleaning all the filth off.

Wow, what a PITA.  Good thing you were smarter than the pulley!

Hello Ron,

I probably have some pulleys laying around here if you need one. Is yours a tappered shaft (late) or a straight shaft (early)

Hopefully, you have not upset the front seal by applying the heat to the shaft. I did this same thing and had to replace the front seal. Not a big deal but something to be mindful of and you certainly don't want to find out after you've installed and filled the reservoir with fluid.

Hi George, one of the reasons for pulling the pump apart was to replace that seal, so heat damage was not an issue.  Now I'm reading the other recent pump thread about "O" rings and I decided to order the "O" rings from the dealer using the parts numbers provided by Dave G and wagas.  I'll replace those when the new ones arrive.
