Ok , I'm adding power steering to my car, trying to install my pump and I can't figure out why the nut and washer will not fit on the one stud on the back of the pump. One stud is 1/2 long and the other is 3/4. So the guy who rebuilt the pump, did he reverse that stud, or maybe someone cut it before me. How can I fix this, do I need another stud or is it reversible, or do I need to find another. The nut just barely fits without the washer, I'm assuming there is supposed to be a washer I don't know.
I attached a couple pics.
Any help would be great thanks

Any chance he put the stud in backwards ???

That's what I'm wondering, I've never had one of these apart so I'm not familiar how they are put together.

It's bee awhile for me but i seem to remember there being two different lengths on the fastener. If you have a shop manual handy they sometimes have pretty good pic's/ instructions/ illustrations

If it doesn't need to appear OEM, try a Nyloc nut, no washer.
Shortest such nut would be called a jam nut.

there are thin nylock nuts available as well.

Unscrew the stud, it'll be obvious if it needs to be flipped

What he said. Pretty sure it has a long side and a short side. Unscrew and flip it.

Yep, the guy who restored it put it on backwards, I just flipped it and it was the correct lenght. Thanks everyone

thanks for the follow up

glad that was a simple, no cost fix !
