Troll Hunter Posted November 17, 2017 Share Posted November 17, 2017 I'm in the very early stages of painting various components of my 1991 300Tdi CSW. I was cleaning my PAS box in readiness for painting when I found this damage: I've been aware of a very small leak of power steering fluid for a long time, but have never been able to find it. Here it is, with at least two failures, the main one at the seven o'clock position and the other at the nine o'clock position. So, what are my repair options, if any, please? Is it feasible to weld, re-tap and have the seat re-machined? Could plastic/epoxy metal be used? Any other hare brained, out of the box options I could follow? Many thanks, in advance, for any suggestions that save me having to import a new box. Mike Quote Link to comment Share on other sites More sharing options...
Davo Posted November 18, 2017 Share Posted November 18, 2017 Do you have a hydraulics shop you could take it to? It's no different than something a lot of heavy machinery would have, just a casting with a tapped hole. Maybe someone could TIG it and redo the thread.

Daan Posted November 19, 2017 Share Posted November 19, 2017 That has been done up to hard by the looks of it. I suppose I have to end this reply with pearls of wisdom : Advice is what you ask for if you already know the answer, but wish you didn't!

I was wondering why the OP doesn't want to import another one. It couldn't take that long, could it? Over here it's at least two weeks to get anything from the UK, which is a fair while when you're in the middle of something - certainly long enough to forget what you were doing.

mickeyw Posted November 20, 2017 Share Posted November 20, 2017 From what I can see, the o-ring sealing face is clean and undamaged. I can see the thread damage looks pretty nasty, but unless the damage is actually preventing you fully tightening the union I am surprised it's leaking. Maybe you could try a new o-ring and see if that helps. As far as repair options go, I would think replacement is a better option. Quote Link to comment Share on other sites More sharing options...

Troll Hunter Posted November 20, 2017 Author Share Posted November 20, 2017 Many thanks for the recommendations, and I'll be phoning my local hydraulics specialist shop today. I'll update with the result. The only reason I don't want to ship a replacement across is the cost. Purchase plus freight plus customs and taxes plus no core refund (return freight cost), gets very spendy. Mike Quote Link to comment Share on other sites More sharing options...
Ex Member Posted November 20, 2017 Share Posted November 20, 2017 (edited) If you are left hand drive, you can use a box from a Discovery 1, which you can find cheap at any wreckers. Edited November 20, 2017 by Red90 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted November 20, 2017 Share Posted November 20, 2017 Yes, D1 and RRC should both swap over IIRC. Quote Link to comment Share on other sites More sharing options...
Troll Hunter Posted November 21, 2017 Author Share Posted November 21, 2017 Red90 and Bowie69, many thanks for the tips. I've examined the end of the hose from the steering box to the reservoir and whoever fitted it has totally fubared it. Replacement hose to be acquired. Many thanks again to all who have posted advice. Mike Quote Link to comment Share on other sites More sharing options...
