[Webby the Bear]

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

Those little plates are part of the impeller of the pump Webby

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

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

What were the symptoms

[Webby the Bear]

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

[Marks DTM Calib]

And he diagnosed bearings pmsl......oh dear

Pressure relief valve I would say

[Webby the Bear]

thanks mark. I was very careful not to advise as I didn't know what the problem was. so this is what he was told 

is the PRV on the rack itself?

[Marks DTM Calib]

Its normaly on the pump and is often under one of the bolts that is on the side of the pump body

[Webby the Bear]

Thanks mark. theres a big bolt that has two washers, has a hole in it and fits one of the hoses to the pump.... is this it?

[Marks DTM Calib]

Quite possibly, yes

[Webby the Bear]

is it usual that theyre simply blocked with goo?

The vanesd wear down=not so good as a pump then

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.
