In case anyone cares took the Mh cab to landfill and it weighed 2200 lbs. Less than I figured.

I will venture to guess that changing the filter will resolve this issue but I would also change the oil as well should be (motor oil) the oil should stay semi clean not crank case black if it does turn crank case black I would take a hard look at the compressor as to why its not draining back to the pan, the coupling area of the power steering pump should not be getting pressurized crank case oil.

When I replaced all the lines I put fresh oil in and I wondered why it got black so quick. After I found the line that was kinked shut I figured it couldn't get oil and somehow was sucking it out of the compressor. Worked fine for a couple weeks and then started again. Thanks for info on filter. Filled with fresh oil and I'll try it out next week.

is the filter plugged,? is the reservoir  plumed properly? is there a dip stick on the canister fill plug? is the oil black?

I never knew there was a filter in them. Replaced it today. It has a dipstick and yes the oil is black. 

85 R model power steering was making oil. Changed pump with one off parts truck seemed ok for a couple days then the same thing. I found the one line was collapsed, it was just rubber hose so I replaced all lines and it was ok for about 3 weeks now it's making oil again and although it's not full it's pushing oil out of the reservoir.  I figure it has to be sucking it out of compressor but don't know why. It's only about an inch over full so I don't know how it's coming out of reservoir and running down frame. Any ideas?

I generally send $75 to $100, which is cheap for generally the sheer amount of info you get from them. All searched by hand by volunteers.     Paul

Thanks 

What amount do you usually send for the information?

Nice save. My first driving job was in a 69 r model. I ended up buying it.

Looks good. I would like to do that to my r model

Looks good

I also used it on my oil pan on my Ch and did everything the directions said and still blistered up. Winters around here are hard on things.

Ran today and everything worked like it should.

I checked mine today.  Last week when I would get into it more smoke would roll than normal and towards the end it would get a little gray.  I had the mini-me push and pull the parking brake knob and I could not feel it move.  I took mine of and shook it and nothing happened so I put air to the inlet side and it blew out the other so I stuck it in the vice and pulled it a part.  I figured it wasn't working to begin with so what to heck.  It has two buttons on the inside with a spring in between. A plastic lock ring and a diaphragm.  I suppose what happens is manifold pressure creates a vacuum and pulls/pushes the valve to allow compressor air in to reduce smoke.  

I cleaned it up and removed the lock ring and looked under the diaphragm and seen it had some oil so I sprayed it out with some can solvent and air then reassembled it and put on the truck.  With mini-me pushing and pulling the brake knob you could feel and here it click open and closed, which it wasn't before.  If It starts up again I will check the valve on the pump and probably replace them both.

What does the deal on the pump do when it gets air?  I was going to take it off but ran out of daylight for what I had on my agenda for the day.

Yours looks a little different than mine. The way mine is made you can't take it apart.

Are they rusting yet?

Not yet but they've only been on a couple months.

A quick check to see if it's working.

Nail the accelerator with the spring brakes applied, exhaust should look like a house afire.

Release the brakes and try it again you should see a very noticeable difference!!!

That's what I did. Definitely a difference. I don't mind the smoke but every time I started it I was blowing out a shovelful of soot.

I think it would only take one week if everyone parked them. No food, gas or anything else moving I don't think it would take long to get their attention. But it will never happen.

I've bought 2 sets. The ones I have now are ok the set I had on my other r model I had to bend them a little to get them to stay latched.

I think I have it working now. I pulled it off and found someone had soldered the hole shut in the fitting that goes into the manifold and the end of the line going to the pump. So once I fixed that and hooked the line up right seems ok. Thanks for the help. I've never had one hooked up on any of my trucks so wasn't sure how it was supposed to go.

Didn't know if you ever found a light. I have an aluminum based one if interested.

I have a 5 speed trans. and a set of 5.73 rears for sale.

I have the one line hooked up wrong on mine. Will switch it tomorrow and see if it works, if it doesn't I will be interested in one. Thanks

Here is a 691GC218CP5X that came off a 1985 285. 

The yellow dot is the port for the manifold SIGNAL.  The red is OUT to the pump.  The lime green is the port at the end for air IN.

Thanks for the picture. I didn't get a chance to switch the lines today but I'll get it tomorrow and see what happens.

I'll try switching it. There was a plug in that port and the line was there so I thought that's where it went. Thanks

The reversing valve( I guess that's what you call it) on the intake on mine has two lines coming out of it, one goes to pump, other to firewall to brake release. I also have a fitting something like a petcock which seems like a plug when I took it out. The valve on my parts truck had pipe plugs in every port so what I'm wondering is should I have another line going to the third port to make it work? At $250 for a new one I like to make sure mine is bad. It was unhooked when I got it but it smokes worse than I'd like.

If everyone would just park them for a week it might put a stop to everything they keep trying to pass. I know it will never happen though. They used to go on strike but I don't ever see it happening now.

I was at R+R Mack and he said he would have to call the supplier. He said they were a hundred and some odd dollars before. He checked on it and called me back and said $250 plus shipping and I said no thanks.
