And the Lifelines are good for 5 years? -
Just a reminder……….Any repairs to the pneumatic system on our coaches should use only DOT certified fittings, components and air lines. As Joe pointed out any NAPA store can provide not only the hose but fittings also, and as an alternative all truck parts shops are also going to have DOT certified hoses, fittings and components.

Andre, isn’t Teko calling you…..

They are stored in a hole on every bake chamber that has spring brakes. Mine has 4, 2 on the tag and 2 on the drive. I did a thread on this subject recently. See link below.

It is impossible to defend ourselves against people who offer shitty advice.
In case my remark above wasn’t specific enough let me rephrase it.
Weigh the coach and get an axle reading of the weights on each axle, or if possible get the weights at each wheel or pair of tires such as on the drive axle.
Go to the chart on the Michelin web site or the Prevost car web site. Look up the tire pressures specified for the axle or individual wheel weight and that is how much pressure to carry. Do the pressures cold. Pay attention to what the charts say and look for where it says to add pressure for worn tires. In case you did not see the instruction about adding tire pressure if the tires wear, that’s OK because I did not see it either.
This is from the Service manual:
OVERINFLATION
Causes tires to run hard and be more
vulnerable to impacts. It also causes
irregular wear. Similar to the wheel
being too narrow.Also from the Service manual:
Unless otherwise recommended by tire manufacturer
for optimized tire performance, use the tire inflation
pressure shown in the application data books for the
particular axle load. Exceeding this pressure could result
in reduced traction and tread life.The above statements from the service manual for our tires should be tattooed on the heads of the people that tell you inflation pressures higher than what the charts call for. Michelin said a few pounds over is OK. But when you get 20 pounds of pressure greater than what is called for our already lousy stopping distances are worse.
If as a Prevost owner you haven’t become a doubting Thomas please try to become one. All advice, including this is possibly wrong and your best and only defense is to use the internet to get the facts. The facts are not going to come from anywhere but the manufacturer’s manuals on everything in our coaches, including the engine, transmission, tires, batteries, etc.
It may be hard to believe, but sometimes (OK most of the time) I make stuff up.

The alternate route of 65/231/10 worked out well. The only notable traffic was just outside of Jacksonville where an accident created a 30 minute parking lot. While it was sad for those involved, it was an opportunity to take a lunch break.
For the route, I took two equal legs and overnighted in Troy, AL.

Congratulations Chuck and Lisa!
I don’t know how long you’ll be hanging around the area, but I’ll be back in town next week.

Add Fastenal to the list, but I have had the best luck with Grainger.
Make sure they are DOT fittings.

Sorry, but there is just no way that a tune up and jake brake adjustment are going to let the engine run 200 RPM slower at the same speed.
We played around with transmission ratios and rear axle ratios all the time when specing out trucks to get the best fuel economy. 200 RPM’s is a huge change and it will never happen with a tune up. Period.

Try posting some basic information about the coach like … “Looking for information on 1999 XLV Liberty #407; anyone have any background information on it?”
We see prospective buyers post that kind of information from time to time.

Your Webasto heats the engine when on for your vintage Liberty, there are no buttons, but I’m relying on memory here.

Thank you, can those be ordered from Liberty Coach? Or do I need to get it from Prevost?
Thanks for the information I love this coach but I am still learning new things everyday. Maybe one day I will have it all figured out.

Ok, the reason I’m asking is, I have to leave it for a few days not plugged in. In the past, when checking that the Gen will start as the batteries go down when on auto start, the voltage shows 23.2 Volts (I have a 24v system). I just thought that this was too low, guess that equals 11.6 volts.
Should I raise that up, if so, what menu do I go into on the inverter?
I very rarely use the auto start, I normally like to start the gen when I want to before they get too low, but since I won’t be with it this time, I want it to start.
I will have someone there with it, but they know nothing about the coach.

I was visiting with some local to me RVers and they were telling me they had 100 psi where they were at because the local water tower was nearby? IMO, 100 psi would mess up the plumbing. Use the house pump and refill when necessary is what I do.

Hi Linda & Kirby, you might want to read this thread: https://prevostcommunity.com/forum/threaddetails.asp?Category=Pneumatic&ThreadID=6165
This is what I put on our bus, a 96 Liberty 40’XL, S-5665: 4 of the #630104 for the drive axle, and 4 of the #630259, two each for the steer and tag axles.
By the time I paid Prevost the shipping and tax the cost was $180 each a couple of mths ago.
