Power Steering High Pressure Line 900

Maybe this is a crazy idea? But I am wondering if it is worth a try.

Alas, I have been instructed to reduce my 940 collection. The best of the 4 went to the glue factory this past week. Donated to WBUR. It was the best mechanically, but my teenaged "retired" it in a non-injury head on about 4 years ago. I've been storing it every since, thinking I would need parts, but finally made a rash decision and it is gone.

One of the three left, has a power steering leak.

The Brickboard info on power steering describes replacement of the high pressure line as challenging, in that it is difficult to access the end nuts. I have a variety of issues on this car and I do not want to get too deeply into the power steering to find that there are others beyond my reach and budget. I would like to fix it enough to get my annual inspection sticker this month and they assess where I am headed on the other repairs.

The line has a tiny pin hole that is obvious and accessible. A friend of mine, who is mildly competent, thought he had a good idea so he wrapped a piece of rubber around the pipe and secured it with three hose clamps. That did not work, although I do not quite understand why. Maybe I should try this again, as I am more adept than he is.

My next thought was to screw a tiny machine screw into the hole and then I thought if that could work, why not drill strait through and bolt the hole from both sides. Myabe use a couple tiny soft copper washers cut from a oil sump drain plug.

I realize the through bolt will impede the fluid, but my guess is not enough to have any significant adverse effect on it doing its job.

Whadaya think?

    A pin hole probably appeared due to corrosion of the line. That might be an indicator that the area around it is weak (thin walled) as well. I don't think a through bolt or screw fix is going to prove successful.

    There is good access to the attachment on the pump end and the other end isn't too bad once you can get the car up on jack stands or perhaps ramps. I just replaced one last week on a 740 which I believe is the same setup. It was not that difficult of a job... messy, but not difficult.

    O'Reilly's got the hose for me the next day for $26.

      RANDY,

      Got any hints about how to approach the difficult end or is is just something you have to work through when you get there. My hands are small and dextrous and I am use to working in tight positions from doing engine work on a sailboat. But, despite that I was put off by reading the FAQ on this subject some time ago.

        The pressure hose is the upper hose attached to the rack and is a 19mm hex head. No issues getting a socket on it. Perhaps cleaning up the area some to help avoid getting dirt in the rack opening once it is loose. Mind the copper washers.

        I taped up the fitting on that end before I snaked it into position so as not to scrape any crude off of the bottom side of the car and have it enter the hose.

        I don't think is is a difficult task but I haven't read the FAQ's. Again I am assuming your 940 and my 92 745 have the same setup.

        Good luck,

        Randy
