 Topic: Wd45 power steering leak
Posted: 31 Aug 2023 at 11:51am |
Hi a’ll!! So I’m getting really tired of this power steering leak and can’t figure out how to fix it… I’ve replaced the O-ring but it helps for awhile than it leaks all over again…

I'd scrape all that paint off both surfaces, run a flat file on each side (unless both sides are "somewhat" flat), and use a touch of rtv silicone in the o-ring groove.

The boring under cap is only a dust seal. There is orings on spool that need replaced. MACK

Look at the barrel when you have the spool out. Water will form pits and the o-rings will not seal.

I had the same problem. Mine would leak oil while it was not running. I did everything I could think of twice. Finally, I noticed the cap was slightly sprung or warped. I straightened it that stopped the leak. Good luck, this kind of problem can drive you nuts.

Thanks Mack!!! I didn’t even know there was O-rings there…. I replaced the O-rings and it works like a good Allis should!!!

It doesn’t have anything in there to catch my finger nail on and no rust in there (it surprised me) so I think it’s ready to roll!!!
