PAS pump replacement

bozothenutter · Oct 3, 2019

With mine getting a bit whiny...
Is there such a thing as a 'best' replacement?
Old thread on here suggests Spidan rebuilts
Any opinions?

Usr117063 · Oct 3, 2019

Is it just whining or any other symptoms?

Usr117063 · Oct 3, 2019

Mine is very loud too

bozothenutter · Oct 4, 2019

Louder whining that it used to be, possibly related to the change to a quicker rack.
Car is on nearly 150k Km

@bozothenutter Any news mate? I spent sometime searching about pas systems one night, ended with how they do it on F1 lol. Theres some american companies that do pumps and you can put different size fittings to allow more or less fluid pressure through for variable resistance, would need to be custom mounted but would be a far superior system to oem

not really, still trying to decide if the noise is normal, but just louder because I removed the firewall isolation...

or maybe replace with an electric pump unit (cupracers had one)

I would replace the PAS with EPAS tbh, my PAS went and i was lucky it didn't take out the engine or anything else. I have been told that the tolerances on the pump are within 1mm. I did get one from eBay and it was out and used a hub puller to "adjust" it.

not gonna happen, just fitted a brand new PAS quick rack.
Thanks for the info on the pump though, another reason to add an electric PAS pump....

My pump's very noisy... sounds like I have a supercharger... I'm not using the car on track and just wondered if anyone had gotten a decent standard pump off eBay or elsewhere they'd recommend ?

bozothenutter · Mar 31, 2020

So, just some faffing with hoses and electrics and done?
Locate in original position even?

If you're running a Vito pump then you can put it anywhere you want mate😂

Usr117063 · Mar 31, 2020

Make sure its not leaking fluid at the end plug before you spend money.

Nah I'm a real bloke and have no PAS😉😂

bozothenutter · Apr 3, 2020

well ordered the damn pump, so now wait until I can rent a lift get cracking.
only three wires so ground, positive and switching right?

bozothenutter · Apr 8, 2020

I was close, grond, positive and alternator.
So the pump only turns on with engine running.

Question:
Do the PAS lines have to be partial hard line, or can the be all hydraulic?

I used flexible on mine. Granted the high pressure hose wasnt cheap, I wanted to be 100% it was up for the job

did you write down the fitting sizes, would help a deal not having to reinvent the wheel.

Merc pump is quite heavy btw....

This for the high pressure. They are -6 thread so I think the adapter was m14 to -6 rack. The return line I used -8 ptfe braided as I wanted it to be high heat resistance and secure.

I would just sell you the hoses I made but I barely got any use out of them so will be going on a build further down the line

Thanks guys... I did the job a few weeks ago [along with a ton of other stuff as I took the engine and gearbox out of the car] and used this one off eBay. It's probably the one @MrBlonde used ? Seems alright so far, although I have to say there's still a whine when I start the car, but it goes away after about 30 seconds.

Pardon our interruption...

MrBlonde · Apr 11, 2020

Yes mate exactly the same pump & your wine is prob the belt needs changing or adjusting mate @Davyboy888

I replaced a ton of stuff including the timing belt, dephaser, auxiliary belt, aux belt pulleys and tensioner, all the oil seals, sump gasket, exhaust and inlet manifold gaskets, clutch etc... etc... all with genuine Renault parts. Prior to that the alternator and water pump were replaced.

Could also be the air con compressor if you have one. Can see if the sounds different with the air con clutch engaged or not.

Ya that's a point. I've not gassed the system since I've had everything to bits, so will try that when I have.
