Re: power steering pump pulley removal

If you go to Autozone, they should have a puller in their tool loan program,
just pay the deposit and get it back when the tool is returned.
Hope this helps

Or if the pump is off...
Just take a couple of 1X4's and hang the pump by the pulley.
Then hit the shaft till the pump falls (catch it before it lands)

Re: power steering pump pulley removal

Up until 1975 the power steering pump pulley was retained on the pump driveshaft by a nut. The pulley and driveshaft had machined keyways for a 1/8 x 1/2 Woodruff key. Except for corrosion, the pulley should come straight off fairly easily when the nut is removed. If your pump has a driveshaft with a male thread and a nut on the end, this is the type of pump and pulley that you have.

Starting in 1975 both the driveshaft and pulley were changed to a press fit design. This type of pulley and shaft requires that you use special tools as described in the earlier posting. You must use the correct tool to pull the pulley from the shaft. You must also use another special tool to draw the pulley onto the shaft. If you do not use these special tools, you will destroy the pulley and probably the pump as well. This type of connection has a pump driveshaft with an internal 3/8 hex and a 3/8-16 female thread machined inside the driveshaft which you can see looking at the front of the pump.

OOPs.......

ignore what I said unless your pump is older than 1975.
On the old pumps my system works great - always has.

Re: power steering pump pulley removal

The special pullers are pretty easy to find, work great. The puller has to grab the groove on the hub, not the pulley OD.

Re: power steering pump pulley removal

75 was a h*ll year in my opinion. The Z28 and SS Camaro were gone along with all the other Muscle cars. Compression dropped to like 8:1, Sunoco 260 dried up, just look at the 75 T-Bird for example My God. Detroit just started sticking things together like power steering pump pulleys, welding on door hinges, plasticizing and attempted to sell a us performance in a package that truly sucked. No wonder enthusiasts turned to the European and Japanese Models. Man that 75 Toyota Crown which looked like an Audi or Nova depending on which direction you looked at it was Ugly but man it was built Tough and Fast It had a Full Heavy Duty frame, 15" wheels, over head inline 6 with 4 bbl and 5 spd tranny that could out perform the competition including Volvo and BMW. North American cars were not even in contention.

Here's a PIC of a 75 Toyota Crown and I believe even Richard Petty was impressed - LOL

This 77 4 Dr looks almost identical to a 77 Chevelle with a Dart Front end ))

Re: power steering pump pulley removal

I don't know why, but the assembly plants always had problems assembling the Woodruff key and then torquing the nut to make the connection of the pulley to the power steering pump. When the interference fit pulley and pump was introduced in 1975, power steering warranty improved.

This same interference fit connection (pulley to power steering pump) is still used on all Saginaw pumps today (30+ years later).
