power steering pulley removal

[68c10owner]

Just took the kids to school and noticed a nice puddle in the driveway when I got back. Seems to be power steering fluid. Cant find any obvious leaks from the hoses but does seen wet behind the pulley. I see evidence of fluid being sprayed around the front of the engine. Figure Im due for a pump anyway and they are fairly cheap. What the best way to get the pulley off without a air compressor? This is in my 85 GMC C1500 305.

The pulley is likely just pressed on: no retaining nut or bolt.

Use the proper puller that grabs the groove around the outside of the pulley's hub 'nose' and remove it with common hand tools/wrenches.

There are common jaw-type clamps, like this one:



And also ones that use a collar around the clamps, like this:



Most auto parts stores should sell or rent them.

After taking a second look and looking at just the pulley mount you are correct that it is a press on. I was more concerned with the source of the leak and just figured it had a nut like my old chevelle had. That makes it a bit easier. Thanks.

When I needed to do that, I was able to borrow the proper tool from Autozone, which is where I bought the pump from.

Use the puller in the second pic, it safely grabs the groove on the shaft.
And the kit also presses the pulley back on.
DO NOT use a jaw type puller, it will bend/warp/distort the pulley and render it useless.
Parts stores sell/rent the set, I bought mine at HF for less money and it works just fine.
Just note, it takes a few minutes to figure out how to use it and which length bolt to use.
Once you have done the job with that tool, it's easy after that and only takes a minute to perform the task.

Thanks guys. How did you reinstall the pulley? I dont have a press to press it back on. Hammering it back on with a block of wood would work but does it mess up the pump? Use to install harmonic balancers that way on old 283/327 cranks that werent drilled for a balancer bolt but never liked the idea of it.

The second puller in the picture is also used to press the pulley back on. NEVER try hammer on with a block of wood etc. Will screw up your new pump for sure! (Ask me how I know this)

I didnt think it was a good idea which is why I asked. I didnt like doing it on my balancers back then either but I was a dumb kid and didnt know any better.
