Power steering ID
I need to ID this pump. It's got a 3/4in shaft with a press on pulley. The one listed for our trucks use a 5/8 shaft w/key (furthest in picture).
The keyed pump and pulley I have won't line up properly, but I think the other will line up when pressed on. Here are some pictures of the pulleys PN'# if that helps. The first is the one with the 5/8 w/key, the other is the press on 3/4. Thanks s/t ![]() ![]() ![]()

here is a copy/paste by Shane that I found on search.

I have a ZOOP'S press on 3/4" shaft single groove pulley if you are interested, it is polished billet FORGED aluminum , not the Cheap Chinese cast version. Let me know if you're interested & I can get you a pic or two. __________________ Keep On Truckin' Shane __________________

Re: Power steering ID
The press on pully pump looks like a 73-up style pump...
