Default Discoveries upon removing the alternator

Well the story [https://rennlist.com/forums/showthread.php?t=386706] continues into the next chapter...

The battery was not recharging and the voltage needle is bouncy. So I'm going to take the alternator in for a test. Upon removing it, I've discovered the following:

1. The brown oil level wire is badly cracked, as is the protective rubber housing that surrounds the metal connection to the oil pan. (photo 1 - sorry it's so blurry)

2. One of the two (I think these are oil pressure contacts points) leads shown in picture 2 is broken. The one that is visible in the picture is fine, but the other one has lost its final contact point. I think this is a pretty simple repair, even for me.

3. Regrettably, I see power steering fluid leaking from the pump above (photo 3). Is this a difficult replacement if necessary. As photo 4 shows, the air tubing is very covered with dextron fluid.

So I'm in there now. Any suggestions would be greatly appreciated.

Peace,
Tim

Often the feed hose from the reservoir to the pump leaks ATF onto the pump. It is not very common for the pump to leak.

Hi Tim,
Sharksin's site has some info on power steering hoses

I think it's a messy job to change, but doable. On a happier note I finished your alarm harness today. Best of luck with alternator and ps leaks.

The hoses on the PS reservoir commonly leak right where they connect to the reservoir. Reach underneath and see if your hand comes back wet from the ATF. If so, you can either replace the hoses or, as others have done, cut off the ends and reattach. Sometimes it's enough just to attach a fresh part of the hose to the reservoir (cut off as little as possible!). With all the stuff spinning there, it's easy to believe that you've got leaks all over the place. It gets dirty and looks like oil, adding to the confusion.

Tim, I recently replaced my power steering hoses following Sharkskins directions. I first tried to cut the end off the return nose and stretch it, but I cut off too much. Not a very difficult job really, but you will need the alternator out to do it.

My alternator problems started after doing this repair, which I think may be attributed to leaving the cooling shroud off for a few weeks while I hunted down the replacement hose --I think it's critical that you replace that hose and keep the shroud on.

My power steering feed hose was leaking also. It just needed the clap tightened on the hose. I also have the torn out alternator cooling hose. It's on my list of things to fix (way at the bottom). Jason

Dave, I went ahead and did this yesterday. The ATF fluid was indeed located on the underside of the hoses and dripping from connections faults, not the pump itself. I cut off about 4mm from the ends of each of the two hoses that connect to the reservoir. I have reattached everything and, as yet, have no leaks. That's not saying much, however, because with the alternator out, I've not been able to run the car.

At least I've had the satisfaction of tending to a little WYAI project while the alternator is resolved. Thanks to those who've contributed to this thread.

With the alternator out of the way, you have very easy access to the PS hoses. I had leaks there under the reservoir/filter. Tried to cut a little off the ends and re-clamp on the little nozzles but that didn't do it-- the old hose was too well cooked and hard. new hoses and a replacement reservoir/filter did the trick. Again, easier now with that alternator/PS console dropped so there's room to get to the back of the pump. The reservoir/filter should be replaced as PM item-- Less than $30 IIRC from 928 Int'l last time I looked.
