Title: My mate's new PAS pump fitted... but can we repair the old one....
Post by: Webby the Bear on 16 July 2013, 14:39:44
Afternoon fellas, hope you're well.

I fitted my mates new PAS pump but i'm now stuck with his old one. And being the inquisitive chap I am I thought i'd take it apart :)

Those little rectangle pieces of metal are the bearings that fell straight out of the bearing holder (??) that sits next to it in the photo. if I can get this sucker going (my mate kindly said I can refit on his car to test it out) then I'll have learned some stuff and perhaps make some dosh on a resell :):):)

so.
shall I grease these up and refit? theres no obvious signs of damage or wear? im thinking, grease, refit and test. what say you? :)

ps this is the pas pump off a 2004 Hyundai coupe 2L SE

Aha! thanks mate. I assumed they were bearings..... so if the bearings have gone where do I find them?

ps, this failed bearing/s was the diagnosis of a mechanic, not just me guessing  :y

Not much goes wrong on the PAS pumps, its normaly a seal or a bit of crudd on the pressure control line.

The metal parts form part of the impeller assembly which actualy pumps the fluid.

That looks like a Saginaw pump to me

it was screeching when you got to either full lock. it was physically stopping the belt and its that rubbing that was causing it

Never seen it happen on a modern system to be honest and there are not signs of scratching or witness marks on the rotor outer in the pic.

Every time I have stripped one its been gunk in the system be it in the pressure relief valve or the pressure regulating part.
