Hi all,

Got a leaky power steering pump, leaks from the top where the banjo comes in.

I've changed the two sealing washers around the banjo and that made no difference, so I removed the nut that the banjo goes into (springs out after a few turns), and there's an O ring in there, I suspect that's the cause of the leak.

Does anyone know precisely what size the O ring is (long shot), or, should I just get a new pump ?

"O" rings are a lot cheaper than a new pump, so worth a try first.
Look in yellow pages for seal supplier, but might have to buy 10 but will only be less than 10p each.

Thanks Tabetha, indeed o-rings are cheaper... New pump is Ł290+VAT

Took the pump off the car last night and removed the bit where the o-ring sits, it looks like a 20mmx15mm (ODxID), but not 100% sure, you can get 19.5mm, 20mm, 20.5mm ones... how can I tell mine hasn't shrunk !!!

The workshop manual actually covers the dismantling of the pump right down to component parts, and says to replace all o-rings and seals, but doesn't state what size o-ring you should use

Think I'll take it to a local o-ring supplier for advice

Best thing to do, and use VITON seals, more expensive but way better.

Well, after closer inspection it looks like the elbow after the banjo connector's leaking, the weld seems to have broken.

However, I am not sure if that's the original problem, I was cleaning the hose after replacing the washers either side of the banjo and I might have tugged it so much so that I broke the weld... who knows...

Anyway, off to get a new hose and we'll see how that goes

common problem greg. i had the same on my 2wd PAS pipe, as well as the turbo water pump on 2 of my cossies i suspect that was always where the leak was from.

i can braze that up for you if you bring it in to work in basingstoke and look for a new o-ring at the same time from our selection here
