In the process of putting my air filter housing BACK in place I remebered that I needed to replumb the air line from the compressor to the muffler. Currently it has a flex pipe from the compressor to a pair of elbows (to make an up-side-down "U") and then about a foot long nipple down to another elbow and into the muffler. So it goes from horizonal (out of the compressor) up then back down to horizonal (into the muffler). My question is; is all that direction changing nessasary? Or can I just get a nipple and put in the muffler and connect the flex pipe to it. There's no drains or anything in all this plumbing so I can see the need for the elaborate design. But, then again I know little about air systems in vehicles. Thanks Nick | ||

Nick As a diesel mechanic of 25 years, I have to say I'm not familiar with a compressor to muffler connection Honestly, I have no idea what you are faced with... It has me stumped. Are you certain that it is a air pressure line that is going into the muffler? We are talking about the exhaust muffler, right? Brian | ||

Not exhaust muffler it's a little thing the book calls a muffler about the size of a quart jar with a peck cock on the bottom and a hard copper line out the top to the wet tank. I assume by it's name it has something to do with "muffling" either the sound or maybe the pressure fluxuations from the compressor. That's just a guess but it's there none the less. | ||

drain cock, drain valve, little thingy you turn and let the water out of your tanks. Ya'll know what I'm talkin bout What about condesation 2D? I've run air lines in shops and run the line lower than the outlet to let water drain but this deal would run all the water into the muffler thingy so I'm guessing eliminating some of the pipe would help with the water but thats a pretty much baseless guess. | ||

Who you callin' a petcock, MISTER? He he he he The idea of all the plumbing is to allow the compression heated air to cool enough in the first few feet to allow any moisture to condense out of suspension. Sounds like what you have is called a ping tank, and is meant to condense the moisture so it can be drained off via the petcock Brian | ||

So I probably need to leave the extra pipe in place to allow extra cooling, or will the ping tank cool all that's needed? | ||

Nope, the ping tank is where the moisture collects, the extra piping is where the air cools. Brian | ||

I got another question for you guys. I looked in DA BOOK today and saw that it looked like a coil of pipe is supposed to be there not all this mess that's there. Is something like that still used and can I still get it so I can get the system back to it's original configuration? | ||
| BrianMCI96A3 (65.160.212.202) Rating: N/A |
Nick, actually I was going to tell you that coiled copper tubing would also work in that situation, but I figured your setup was original. You'd just need the compression fittings to replace the pipe fittings. 3/4 in tubing ought to work. Brian | ||

I only wish it was original Brain. If I had got her before the last guy that had her I wouldn't have near the work to do. He sure made a mess, but I suppose he did what worked for him!!!  | ||

Nick.... I bought a '79 MC9 from a "church" charter operator that got it from a major charter/line operator, that got it from.... ? I'm finding a 18 tons of cobbed up jobs and make-do repairs, so your not alone. It just has to be racked up to owning an old machine that's had over 25 years of different hands in it, all attempting to keep it rolling for the sake of the almighty dollar. In my case, the guy I bought it from had nothing to do with how any of the previous repairs were made. I'd wager your situation is the same. I think the only way any of us would end up with an all original unit, would be to buy one new, right off the factory line. It'll get better, Nick. It always does. | ||

I don't mind it so bad now I just laugh and keep going. At first however it drove me crazy. | ||

Uh-huh. I mentioned to a part-time diesel mechanic, that the more I looked, the more I found wrong. He said in a real matter-of-fact tone with full beer-breath: "Stop looking". Kinda' like my doctor, after I tell him it hurts "when I go like this", and he tells me "don't go like that". Probably his brother.... | ||

I have to say you fellas make me feel good... Because while I have found quite a few things that could stand mechanical repair, it really seems that most (most, but not all) of the work that was done on my coach was done right. And I felt pretty lucky before... Brian | ||
