brian in buddina Posted 7August, 2020 Report Share Posted 7August, 2020 My power steering return line(item 39) which goes back to the power steering tank (item 20) leaks profusely. The rubber hose (item 39) is dated as 2004 and has perished and won't fit back on the tank without leaking. It is a 10mm inside diameter hose. I have tried cutting it down but it just cracks and leaks. The other end of hose (item 39) has a mechanical compression fitting as per the second photo. Clark's Garage mentions replacing this hose but does not mention about removing or reattaching at the factory mechanical compression fitting. Rookie question: what do I do? Yes, I would like to keep the power steering. I should replace both hoses from the tank due to their age. The Supply line (item 26) from the tank won't be an issue as it has endless hose clamps on both ends. Is there a standard (non Porsche) mechanical fitting, that I can do at home, that replaces the factory mechanical compression fitting?

Fishcop Posted 7August, 2020 Report Share Posted 7August, 2020 Head to Enzed, Pirtek (or any hydraulics specialist) and just have them remake the line using the original end. Rob 1 Quote Link to comment Share on other sites More sharing options...

Yep - I've done the same with our old E46's hose, and from memory your S2 has had a similar hose replacement. Fishcop 1 Quote Link to comment Share on other sites More sharing options...
944s2cab Posted 7August, 2020 Report Share Posted 7August, 2020 Make sure the hose they put on is compatible with ATF Quote Link to comment Share on other sites More sharing options...
brian in buddina Posted 7August, 2020 Author Report Share Posted 7August, 2020 thank you gentlemen. Is there an alternative option of a "do it yourself at home" fitting? Plumbers have available a compression fittings, copper to copper & copper to plastic. I am not suggesting a using plumbing fittings but surely there must be another option for the rancher/farmer out in WopWop who doesn't want to fly in a Pirtec rep.

Peter M Posted 7August, 2020 Report Share Posted 7August, 2020 Brian, Since 39 is the return hose to the reservoir the pressure in the line will be very low and hose clamps would be most adequate. If you carefully cut the ferrule off with a number of longitudinal cuts with a thin angle grinder wheel, you should be able to disassemble the joint without damaging the barbed fitting underneath. Repco sell oil hose in 8 and 10mm ID by the metre so you might still avoid Pirtec yet! brian in buddina 1 Quote Link to comment Share on other sites More sharing options...
firstone Posted 7August, 2020 Report Share Posted 7August, 2020 Would you consider a plumbers cutting tool. Maybe your mitre10 will have one. Cut it and clamp it. A flaring tool is easy to pick up too if you want to go that far. brian in buddina 1 Quote Link to comment Share on other sites More sharing options...

Cut it and clamp it. A flaring tool is easy to pick up too if you want to go that far. I do have a very small plumbers cutters tool in my tool box! I noticed this morning on the unnamed item which looks like a cooling coil which has the factory connection to the rubber hose, as per my photo; the opposite end has the stainless steel endless clamp, as per Peter M. photo. Not sure if that is factory original or not. I can't tell from the Katalogue diagram. Interesting if one end is one type of clamp and the other at another. May be more of a factory production decision rather than fluid pressure requirement. I shall give Peter M. solution a go & try it with the at home clamps. thank you gentlemen.

TINGY Posted 7August, 2020 Report Share Posted 7August, 2020 Brian don't cut the metal pipe, just cut the metal ferrule (carefully) that holds the rubber hose on and slide it all off. Do what @Peter Msaid. brian in buddina 1 Quote Link to comment Share on other sites More sharing options...
jakroo Posted 8August, 2020 Report Share Posted 8August, 2020 My suggestion is to use a hand powered saw and not an angle grinder to do the cutting. Takes longer but easier to control the overall cut as it won't dig in and grab a big handful of metal just when you don't want it to like a grinder would brian in buddina 1 Quote Link to comment Share on other sites More sharing options...
Peter M Posted 8August, 2020 Report Share Posted 8August, 2020 3 hours ago, jakroo said: My suggestion is to use a hand powered saw...... Bahhh! To much effort! A small angle grinder, the pipe snuggly held in the vyce and work your way slowly at it. There is rubber under the ferrule so there is at least a 1.5mm or so between the ferrule and the barb. Beautiful! 😊 brian in buddina, TINGY and Rob 2 1 Quote Link to comment Share on other sites More sharing options...
TINGY Posted 8August, 2020 Report Share Posted 8August, 2020 I'm afraid i am with Pete on this one, nice 1mm cutting disc is way easier to control than a stupid hacksaw blade in my experience. brian in buddina 1 Quote Link to comment Share on other sites More sharing options...

brian in buddina Posted 11August, 2020 Author Report Share Posted 11August, 2020 used a plumbers pipe cutter in combination with a manual hack saw blade, NO BIG CUT IN MY HAND! I now understand why Porsche production engineers decided on a mechanical pressed fitting. The stainless steel band clamp tail end rubs against the retractable light housing. No problem, just need to rotate the band clamp around so it only just about rubs. firstone and Peter M 2 Quote Link to comment Share on other sites More sharing options...
jakroo Posted 11August, 2020 Report Share Posted 11August, 2020 Well done Brian. Despite the disparaging comments above from Peter M and Tingy996, I am not surprised to hear that you managed to get it done safely and effectively using a hacksaw instead of the angle grinder.
