After my belt jumped a notch, I noticed there is a lot of end play in the PS pump shaft. Can I change the fittings and pulley on an OEM pump and use it as a replacement or are there internal parts that have to be changed as well? Even if I order a new one tomorrow from PSC, they wouldn't be able to have it in my hands before Monday.

 

you can install the stock pump and pulley and just run that. Fitting should be the same. You may have lag turning at low speeds, but everything else should work fine.

 

That's what I was hoping to hear. Fittings are actually different as well as the pulley size, but wasn't sure what, if anything, is different internally. I can swap fittings and pulley to the OEM pump.
