Changing power steering pump

[Fordman247365]

How do you get the pulley off the PS pump? Need to change out my pump since I am getting the truck painted, want to clean up some of the leaks I have. Any info to make pulling that pulley easier would be GREAT

i have used a gear puller in the past, but never changed one on a psd before. a little off topice buy i noticed in your mod you are listing a SD IDM. What benifit does that bring to an OBS?

[Fordman247365]

The same as your modded IDM, except the SD one is 120v and modded ones are 140v, the original I took out was 100v. I got the SD IDM for a screaming deal on e-bucket and now I can get my original modded to 140v then it will go back in my truck and my spare will be a 120v

did you notice and difference with the new IDM alone?

I know you can get upgraded PS Pumps, the OBS one has too much plastic. Bill at powerstrokehelp points a model number out. or you can just reseal yours if your having trouble i guess. i havent done the PS Pump but the vac pump i did and had to use a pulley/gear puller. auto parts store rents them out. I went to advanced, sinc ei bought he part there and had the old part with me they let me use their bench and vice.

I havent driven it yet, only fired it up to make sure the idm worked. can the ps pump be pulled out with the pulley still on? that would make life lots easier. when I changed my vac pump, the new one had the pulley on it

You will need a power steering pulley puller/installer. If you look at the pulley you should see a hub with a lip around the center bore where the PSP shaft fits into. The tool is basically a threaded rod with a two piece collar that clamps around the center hub of the pulley. The tool is made for 2 different sizes and you will need to try it with both to see which one fits the hub on your pulley. If you have an Autozone close by, you can rent it at no charge with only leaving a deposit for the value of the tool which they will refund once you bring it back. If you want to purchase one, they only cost about $30.00. Don't try to use anything but this tool because the pulley is not made of very heavy metal and will bend if you try to use a regular pulley puller. You should have just enough room to get the puller between the PS pump and the fan shroud to pull it off.

Hope this helps.

Yes very much, thanks. I thought the pullers cost more than that, I am going to get one so I have it on hand. Looks like I will only have $100 tied up in it even buying a puller.

MATT.......
Love it with the new IDM, cant wait till I get the other one modded to 140v.

before you put the pulley back on use the bolt and a ratchet to bleed the air out

you can buy the puller installer for about 25 bucks.

why would you pull the pulley before you take the PS pump out. that is crazy. much easier after the PS pump is out of the truck and on a bench. IMHO.
