Adding an air fitting

Yahoo Message Number: 1628
I'd like to add a fitting to my coach for filling bicycle tires, etc. Has anyone done this and can offer some advice or instruction on how to add a quick disconnect fitting somewhere on the coach.

regards,

Bill,

I had the dealer do it when I bought my 2002 Intrigue. It went in the front bay, driver's side. I also have a long hose which can fill the tires of the coach if you can't get to a truck stop (although I have trouble getting enough pressure to fill the front tires).

I second that..... Had dealer install.... but it is an easy job. Take out the plug and put in the quick disconnect.
I also have trouble getting enough pressure to air up the front tires.

I have discovered a procedure that allows me to get my front tires up to 115lbs if needed.
First I went to an auto supply store and purchased an air gauge that is built into the air line at the end near the air nozzle. This allows me to monitor the air pressure in the air line while I'm filling the tires. After the coach has built up its' normal 120lbs air pressure, I connect my air hose to the system. Then, while standing next to the tire I want to add air to, I do the following.
1. I insert something into the end of the air nozzle to drop the air pressure down to below 80-85lbs.
2. I watch the gauge as the air compressor kicks on and pressure starts to build up in the system.
(assuming the tire is at 104 and you want it 110)
3. I wait and watch the pressure to climb and as it crosses 100 I attach it to the tire.

4. I watch as the pressure continues to build until it crosses 110lbs. Then I stop and check the pressure and bleed off a pound or two to bring it back to 110lbs.

You've got to catch the pressure while it's "on the rise" in order to get it to build up to the higher pressures. Otherwise you'll just wait and wait and the compressor won't kick on because it hasn't gotten below at certain level which is well below the tire pressure.

Hope this helps.

I am not sure about the 1995 Intrigue, but you should have three valves in the front left compartment. You may have to look from the underside to see them. Two of the valves are drains, the third is for an air hose. The worst scenario is that you may have to add a male fitting for your disconnect, and select the length of hose you desire.

The attached is correct and a good idea if you just want to add a hose that stays attached. You can then open the valve when you want to use it, however, if you want a quick connect valve on this valve and a long hose, you'll have to crawl underneath the coach to use it...

Here's a different suggestion...On the 99 Allure, and most others, open the smaller service door at the front, under the driver's side.
There's a vertical frame member at the front center. Mounted on that is a valve with about six plugged up fittings. Remove one of the plugs and replace it with a quick disconnect air fitting. You can get the fittings from Home Depot, Lowe's, and others that sell air tools.
Takes about $5.00 worth of parts and 15 minute to install. You'll also need some type air hose and the quick connect fitting for it. Be sure to use ribbon tape on the threads...and don't forget to open the valves and bleed the air system all the way down before you start.

Also, be aware that you'll have 90+ lbs of air to the hose, so be careful with bike tires and such. It doesn't take much air volume wise, and most will not take anywhere near 90+ lbs. Take note that when you bleed the air system the brakes will lock up until you restore air pressure. If you have never bled the system all the way down like this, don't be shocked that when you start the engine up, it'll take sometimes 3-5 minutes to build up the air pressure again...good luck.....

On my 2002 Intrigue there are three air valves behind the wall of the under-driver compartment... accessible by crawling under the caoch. I don't remember seeing anything in the manuals about these. And I did not get anything from my PDI want-a-be. Can anybody give me some insight?

Dick, I believe these air valves are used to dump any moisture that may be in your air tanks. My manual says to dump these daily ( I think daily, my manual is sitting inside my coach so going from memory)when traveling. The manual, however, did not indicate exactly where these dump valves were located. I called CC and they told me and it is exactly where you are looking. I opened mine, no moisture was evident.
Took 10 seconds to dump valves. If your ignition is in the OFF POSITION and your coach has been leveled, opening these valves will not release air from your air bags. I did this per CC instructions and it worked as stated.

You do not have to manually dump these valves if you are using the coach on a regular basis. These tanks purge automatically, every so often.
That's

the big air release sound you hear..usually after starting the coach and running for about 10 minutes when pressure first builds up you will hear the air release. That keeps the moisture out of the tank.

Thanks, Jim. I had the same thought before I saw your post. I think that I will check the valves just to see if there is a build up after sitting for about a month.

Jim, First, yes I know the big air release one hears is exactly that, the tanks purging themselves of moisture, What I stated still stands. The Service Manual says to open these valves to dump any moisture present. And it says to do so "often" when traveling.
As I said my Service Malual is not in front of me but I do believe it stated to dump daily. When I talked to CC they said the same thing. Now, have I done it daily? The answer is no! Each time I have opend these dump valves there was no moisture present. So I only dump these valves periodically. Dick asked what these valves were for. Now if ones wants to open these and release any excess moisture, do it. If not thats fine too. Everyone should read your service manual and do whatever they feel is right for them.

Another note for those concerned about this, the air release won't work if the coach is in gear. I think it has to be in park when you open the release valve.

For your information, taken from a couple of Air brake Tech articles on the web.

Virtually all free air contains water in the form of water vapor. We call it humidity.

When air is compressed to 100 psi, the water vapor is concentrated to about 8 times normal!

Water vapor is no problem in compressed air until temperatures drop and condense it into droplets of water.
Then it combines with any other contaminants present and causes freeze-ups, leaks, and corrosion.

To protect your air system from damage caused by water, you must remove enough water vapor from your compressed air to bring its dewpoint down to a temperature lower than the compressed air will encounter at any point in the system.
A good air dryer is the answer

There are four main areas in the air system. They are the air supply, service brakes, spring brake fail safe unit, and air driven accessories. The heart of the supply system is the air compressor.
It is either belt driven by the engine or gear driven off a camshaft. As it's tied to the engine, it will run anytime the engine does.

The compressor could eventually build up enough pressure to blow the system apart if it were not for the governor. It connects to the storage tank and the compressor. When the pressure in the tank gets high enough (usually 120 psi), the governor trips, cutting off the compressor. When the pressure in the storage tank gets down to a specified level, the governor flips back and the compressor can again run normally. The system cycles as you drive.

The compressed air can no longer hold as much moisture as it did, and the moisture condenses in the lines and tanks. Many coaches have an air dryer, while others let it condense out in the tanks. Drain valves are installed on the bottom of each tank to get rid of the water and oil.

Most modern day coaches have air dryers that automatically purge air/water from the air system.

They pop off for a second or so, as air pressure reaches full pressure(125 to 130 lbs).

Our coach is on a Gillig chassi, with an automatic air dryer. In contacts with Gillig and in their owners manual, they say to purge the air tanks with the manual valves, for a couple of seconds every month or so. I would think that the air dryers have improved with time and that manual purging is still an option, but not critical.

I do ours on a once a month basis, just to be safe. Frozen water in an air brake system could be very hazardous!!!!

Thanks, Paul.

I did re-read the section in the manual on the purge valves..... and, when the rain stops, I'll see what has accumulated in the system.
And, by the way, am I the only one offended by someone posting an ad in the file section of the CC forum? Is that acceptable? I understand that the ads attached to the posts are a part of the free Yahoo service but.... really!

At one rally I attended they said that some air systems have a desicant (drying agent) in the air dryer that needs to be changed. I could not find any info on it in my owners manual. Does any one know if there is any thing like this in the CC air systems that needs to be changed?

Air System Explaination (re: foldout D15993 Pneumatic Systems)and Periodic Inspections.

The engine mounted compressor output is piped (A11) to the air dryer (D33 - located above the differential and on the right side - it has a 75 watt electrical heater and desiccant cartridge - see air system group P4,2,-1 Owner's Manual) , from here it goes to the receiver tank D18 via hose H2 and the D25 (air governor) via hose H12. D25 has an over pressure function and releases air when 125 psi is exceeded (can occur often on a trip). The desiccant cartridge is only replaced when required as described in 4.3.1.
Now, read Page UG4-3, 4.3 Air Dryer and 4.3.1. Air Dryer Inspection. "Assess the effectiveness of the air dryer operation every 5000 miles or every 6 months...
Open reservoirs, empty drain cocks and valves, etc.....
Then read 4.4 Air Tanks ..... Three manual drain valves..... should be drained once a month, etc......

It is pretty crass. But, as you well know, some people have no couth whatsoever. Makes one ashamed to be an RVer!
