Leaking PS pump.

[John.]

I know it'll have been mentioned before but......
That plastic screw in plug on the pump, mines leaking from here. I haven't touched it yet, but is it likely to just unscrew to reveal an o-ring that I can just replace then refit and it'll live happily ever after?!
Cheers,
John.

No... You need to buy the kit, plug and oring other it will just blow out again

The big X one?

If so 026145541 for the plug and seal.

Leaking X-plug on the top of the Power Steering/Power Brake Pump

That X-plug is metal not plastic:

"The X-plug has an O-ring which eventually gets eaten by the PS/PB Pentosin fluid in the plug. You can try tightening it to stop the leak but that might not work.

Here is the pump in its native habitat, showing the X-plug.

If you decide to replace the X-plug you need to replace it with a dealer-only part (aftermarket O-rings might not last long in the Pentosin). To remove and tighten the X-plug you will need a drag link socket. The new X-plug and O-ring are as shown here:



Example Drag link socket:



Might need the corners filed off to fit down into the X-plug

I think I have a spare seal you can try first if you want John

Thanks all for that, I thought it looked plastic!

I'll just get new one from TPS (thanks for the offer Mike)

Was looking at the PS rebuild sticky thread.....I'm assuming there's a spring behind the plug??

[John.]

Have ordered from TPS

Who uses what instead of a drag-link socket?!

I have removed my pump to get it rebuilt in the hydraulic shop

in the end i had to get another one as the housing had a hairline crack in the housing, which was found out only after it was rebuilt. So it is also a possibility
