Hey all, just thought while I have to take pump off soon that I may as well replace all the seals seeing the kits are cheap, and being a commodore it comes standard with a slow leak ;). But, my Gregorys manual says extensive knowledge is required and advises against it being done by a home mechanic. However, it shows an expanded diagram of the pump and it doesnt look very complicated.

Has anyone attempted to do it themselves?

V6 btw.

VN exec S1
there is a tutorial in the how-to section that is pretty good. I rebuilt my pump in the S1 VN last week. Power steering is still leaking very badly tho. When you have to take the back of the pump off which is spring loaded make sure you push some wire or a small screw driver through the little hole on the outside of the pump. If i had known this before i did mine it could have saved me atleast 30 mins. Good luck and watch you don't round off the nut on the high pressure hose. i couldnt get it undone so i had to undo the end of the hose from the rack, pull it out and put the nut into a vice. Was pretty dam tight. All the best. Pm me if you got any questions.

Alright cool. Well I just ordered a seal kit off ebay so in the mean time gives me a chance to remove and clean the pump. :) Cheers for the help!

Doesn't that just make you want to do it more?? Like you might have left it alone until you read that, then you just have to? I'm going to try to rebuild my next one I think, my fresh rebuild that I paid money for had a wobble in the shaft.. great.

Well I managed to strip the pump and replace the seals a few days ago. Overall it wasnt too difficult. Very simple pumps. Hardest part is the small snap ring on the shaft (unless you have a snap ring remover). But only needs to be removed if youre replacing the seal on the very front of the shaft, which I did, not because it was leaking, but because a new one came with the seal kit :p.

But heres a quick Q to whoever has done it before:

In order to access the valve, Im guessing the 25mm outlet fitting has to be removed? I cant see it being any other way. And is it a right or left hand thread? Its a tight bastard and dont want to apply force in the wrong direction. :)
