“Rocking the Coach” is not the cause of this.. only the driveshaft , gear set and axle shafts get any stress reversing and driving foreward in that situation . This is a Allison part and Allison failure . Could be a heat treat failure from manufacture, harmonic failure , over/undertorqued flywheel bolts. Put 265,000 miles on our last coach 2000 H-3 , towed stacker , Jeep’s trailers with Jeep’s and anything else . 12.7 60 Series set at 550/1850 .

Parts fit like a charm ! Thanks again!!

I have now owned my coach for 13 months. I was able to repair items and catch other items before they were an issue because of the level of knowledge shared on this form.
Thank you Jon, Tom, Jeff and everyone else
Happy Holidays

Obviously if you have one and the bladder is bad or the pressure is gone you will not know it.
But if you do have one your water will run for a while, as in a minute or more, and then all that is needed is to find that sucker.
That’s is where I am at the moment, but finding it is pretty far down in my to-do list.
To confuse my efforts I added one directly in line with the toilet flush valve, dedicated to the toilet, but it will still function as a whole house system accumulator.
I think the RO accumulator has a check valve somewhere in the system that prevents backflow of RO water to the house system.

Our last coach was set up with a second gear pre-select. We drove it for about 125,000 miles and really liked the setup. When we got this coach, I had it reprogrammed to 2nd pre-select, and prefer that set-up. Don’t forget our transmissions are intelligent, and adapts to the way you drive.

Jon and Tom,
I just spoke with Gina about the new link for the fuel card, to ask where we were to say we were associated with Prevost Community. She said that she will fix that and send you the new link. Not trying to get into your business, but I had read that we were supposed to write in that we were affiliated with the Community.

Same with me on my Jeep Sid, knife switch.

Try “printing” it to a PDF first. Your version of Word might have option off the Print menu. That should make the document smaller and freeze the pictures from moving around. I’d recommend numbering the pages in the footer, putting a date on it, and make sure you give yourself credit as the author.

We appreciate the time it took to put this together as first class. Really helps to have all this info together in one well done presentation.
thanks, Brady

Guys, I think the discussion would be easier to understand if colors are left out and the valves are differentiated by their function.
I believe the two valves Tom describes are the valve that is used to inflate or deflate the slide seals. That is installed by Prevost for their slides and is generally located in the vicinity of the slide pneumatic controls and the slide pressure gauge. THAT VALVE SHOULD ALWAYS BE IN THE POSITION WHERE IT INFLATES THE SLIDE SEALS. Its purpose is to allow the slide seals to be deflated for various service purposes, but except when the slide system is being serviced it should always be open to allow air pressure into the seals.
That valve is actually not a part of the discussion unless for some obscure reason an owner opens and closes that valve.
The other valve in the discussion is the one that when open merges the Marathon accessory air with the coach accessory air and as I stated from the git go, if you are parking your bus in the weather outside you need to insure the seals remain inflated and unless you always monitor your slide seal pressure to insure it remains at 10PSI for longer periods than yu intend to remain without the engine running you need to keep the Prevost system supplied with air pressure from your aux compressor and that involves opening the valve that otherwise isolates Prevost air and Marathon air.
I have no clue about any other slides, or how they get their air supply, but as owners you need to know because water damage can get very expensive

We sell way too many bumpers because of these poor drivers. I had one the other day that was thankful that the guy who hit his truck only got the bumper and not the rest of the front end. I have seen the entire front end taken off. Hood, air to air, radiator, even front tires and occasionally the front axle too.
I go to truck stops to get fuel and leave. I use my fuel card and never leave the coach.

Yes the bladder worked fine, thank you Russ. I sent my ram to Lake Tool last year for a rebuild. They did rebuild it for me but did tell me they were suspicious of some old repair that was done to the ram. They asked me to test it to see if it holds pressure and if not to send it back to them for further repair. I have the ram removed from the bus again and sending it back to Lake Tool tomorrow. I’ll let you know how it all works out. Thanks again for your help.
