RGK Posted February 24, 2019 Share Posted February 24, 2019 (edited) Help! I've recon'd a PAS box...We'll new seals, cleaned put it back together thought I did a pretty good job. Refit, bleed and ran in (stationary on axle stands, lock to lock) worked perfectly. However once on the deck I tested the steering then notice fluid on the floor. The bottom seal leak/ pours out only on right hand steering/ lock. Does anyone know why? Thanks Edited February 24, 2019 by RGK Quote Link to comment Share on other sites More sharing options...
cackshifter Posted February 25, 2019 Share Posted February 25, 2019 Maybe not a genuine seal kit? They seem to be the only ones that have a chance of working. Quote Link to comment Share on other sites More sharing options...
Crofter Posted February 25, 2019 Share Posted February 25, 2019 Was the shaft the seal runs on free rom pits and burrs? I have done them in the past and to my surprise it worked, I probably used genuine seals. Quote Link to comment Share on other sites More sharing options...
muscat Posted February 25, 2019 Share Posted February 25, 2019 If the area where the seal contacts the shaft is damaged / worn / you will have difficulty making a leak proof seal even with genuine parts. Both my 90 and my discovery II leaked like sieves with genuine seals. After fitting Zeus seals both steering boxes are sorted. I believe that the Zeus kit seals to a different area of the shaft avoiding the damaged / worn areas. Bloody tight fit to get the Zeus seals in though! as to why it only leaks at full right lock, I would guess that the pump is producing maximum pressure on full lock - both at full left and full right. Not sure why it’s OK without weight on the wheels... Quote Link to comment Share on other sites More sharing options...

ianmayco68 Posted February 25, 2019 Share Posted February 25, 2019 What was wrong with it before you reconditioned it ? And did you loosen any bolts on it or take anything apart ? Quote Link to comment Share on other sites More sharing options...
toenden Posted February 25, 2019 Share Posted February 25, 2019 If I remember correct, turning one of the ways preasurises the piston via the housing...so to speek, could very well be turning right. It would explain why it only dripples in one direction. /mads Quote Link to comment Share on other sites More sharing options...

ianmayco68 Posted February 26, 2019 Share Posted February 26, 2019 I’m no expert on this but could it be that the shaft is tilting when on full lock , and I think I remember reading somewhere that the big screw on the side of the box with the grub screw under it if tightened takes the play out of the shaft , might be total rubbish but could be a possibility.

RGK Posted February 26, 2019 Author Share Posted February 26, 2019 I spoke to the parts supplier yesterday and their technical person. 2 responses: 1st via sales... "We has lots of instance of this seal failing. One guy tried it 4 times before giving up." 2nd technical... "The plastic/ rubber seal can create hair line mark on the shaft that van course failure when under high pressure" Quote Link to comment Share on other sites More sharing options...

That makes sense. I'll adjust it and let you know. Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted February 26, 2019 Share Posted February 26, 2019 Remember where I heard it now, you have too slacken the adjuster on top off the box to adjust that one . Quote Link to comment Share on other sites More sharing options...
