Couldn't bear to see an empty forum

It does look like the manual leveling will be the answer for now.

I've also discovered that I slowly lose air pressure with the bus just sitting. Not sure how much pressure loss, if any, would be considered within normal limits under this situation. We usually are parked for a minimum of a week, up to a couple of months, at a time.

I also want to learn more about the location of the air tank drain valves and the frequency for this type of maintenance. I don't mind doing it, just want to do it right the first (and hopefully every) time!!

Sure wish I had been able to take in the seminars at the rally!

Thanks for the advice...

Paul,

Your present air loss comments were the topic of one of the seminars and with Bill Jensen from Prevost ready and willing to dig deep into that topic you would have gotten some good information.

Air loss is a very broad subject so when discussing it you need to be very specific. Does your air loss affect the two bus braking systems, the auxiliary air system, or do you mean the coach tilts after you have leveled it? We covered some of this in Branson and I expect because there will be new faces in Sevierville to cover it again there and maybe Pahrump.

Jon,

Sure am sorry I missed that seminar!! Seems to go out of level after being parked for a few days (front drops), so I'm starting to monitor the actual pressure loss (as displayed by the dash guages) to kind of get a feel for the amount of leakage.

No issues when driving, so I believe that the compressor(s) is supplying more air than needed to overcome such a small loss.

My aux compressor seems to come on an average of once/day, usually just after deploying the awning, but it's kind of noisy, so I'm wondering if it may also need some attention.

Anyway, sure hope you guys that were lucky enough to be in Branson took lots of good notes!

Paul,

I wouldn't worry about the Liberty aux air compressor. The one in Gary's Liberty came on during Jon's leveling system seminar and the whole coach started shaking like a dog crapping a peach seed, so I think it must be normal.

The Royale was not quite that noisy, but the Marathon compressor is located in the generator bay, so I could hear a mosquito buzz all the way over at the Krakman's coach when it was on.

Or at least I thought it was a mosquito....

Jdub,,, did ya'll say you could hear a skeeter farting over at Plastikboi's ??

It was prolly farting, as it could not find any tissue !! Or so I hear..

How could a skeeter get in without a code?

We have the DaVinci Code,

And now the P-Krakster Code.... Are all ya'll fixin to make a movie ??

Am also sorry I missed the seminars at Branson. It's good to know that the subjects may be re-visited at the spring rallys though. I have called Bill Jensen a number of times with what I thought were pretty basic questions and he has always been very helpful and much more accessible than some other sources. Am also glad to hear Nick Hessler is still supporting us. Would hope some of us may have occasion to spend a few of our Lewbucks with his firm.

Back to the thread... Since Liberty Coach has installed auxiliary air compressors for many years I wonder if a straw poll of how many times a day these units usually run when the coach is in use would be useful info??? I realize we don't all level our coaches the same and that the Elegant Ladies use air for more functions, to say nothing of the fact many of us old aviators use the flushers more. In our case the compressor runs 2 or 3 times a day for about 5 minutes. What say youse?

[Joe Cannarozzi]

I think it is a moving target Brian. It will be directly related to the age of the coach the amount of air accessories and the level of periodic maintenance.

The best way to see is to leave the bus unoccupied and check it so you can rule out accessory use. The best I ever got to was to have 90 lbs the morning after and that is with one air bag with a pin hole that I'm aware of for sure. That was a few months ago and recently it has gotten to around 65 or 70 lbs in the morning so its time to go over it again. Either the bag is getting worse or the ambient temp is a factor or something new has developed.

A few months back after really going through ours, if not using anything I got it down to cycling once a day.

Phorner if you have a dayton oiless compressor they are a little noisy.

For safety for commercial vehicles DOT requires less than 10lbs of air loss in 10 min with brakes released, or something like that.

Brian,

The answer depends on how dedicated you are to seeking and curing leaks. When I got my coach about three years ago I spent a week chasing even the slightest leak and the compressor (which is left on all the time, even when the bus is unused in the garage) might turn on once a day. Probably less.

Remember that your leveling system uses no air when the key is off. If it leaks it still should not consume air unless you are leaking past the solenoid valves. So that leaves the items such as the air floor, driver's seat, pocket doors, air lock, bed lift, generator air bags, air horns, belt tensioners (key on only I think), etc. If I were to guess the biggest leak sources will be in the steer compartment at the regulator and solenoid valves and possibly related to the pocket doors.

Phorner,

Remember, your dash gauges for brakes have no correlation with the leans and is a completely separate system. If you have an Aux gauge, that is what supplies the air to all the accessories, air bags and is maintained by the Aux compressor.

for sure, ambient affects mine - it'll run once every couple or three days in 80-90 degree weather, and 2 or more times a day in 20-30. i've heard others comment with the same experience. i wonder what it is that changes so much that causes this. hmmmmm.......
