Is there a special tool needed to remove the pulley from V belt type vscuum pump. 1989

 

Kinda...Go to autozone or your local parts supplier and get a power steering pulley puller, then grind a bevel on the outside of the jaws next to the pulley so it clears the concave bevel of the vacuum pump pulley. This is easy to do, the puller is about 12 dollars. The rest of the operation is able to be done without modifications to the puller.
Your only other option is to go to a Ford dealer and have them do it with the Rotunda tool made for the job.

 

Tanks huh David you one smart bugga. Many Mahalos (thanks alot)

 

When I replaced my pump I had to use a hydraulic press to get the old pulley off so I could reuse it. Why didnt Ford just use a slot and key?

To put is back on I think you just tighten the nut or bolt down on the shaft if I remember right.

 

Comes from living in the mountains, ya have to learn to make things work from a limited supply of materials and tools. Last time mine went out it was Saturday afternoon, no shops open till Monday morning. Truck had to run with brakes Sunday.
I took a 15 dollar gamble that I could make the power steering puller work so I could change my pump. It worked well, has changed several since then, so do not loose it.
When you grind it down just be carefull that you do not get the shoulder to thin as it may break. Some of those pulleys are a little tough to get off.
