You may also want to consider giving Parliment Coach in Clearwater a call. They are having a rally (open to all) next week and have some number of spaces for those staying for the Tampa Prevost Show. I heard they still had space for rally participants. LazyDays is a bit closer to the fairgrounds, so don’t overlook Lazy Days. Keep in mind that Lazy Days doesn’t have many sites long enough for a 45-footer. The ureal 45-foot sites are primarily those on the left side of the entrance road. These are close to the office, so you’ll have a place to park your tow. They require coach and tow to stay on the asphault without going into the road. This is impossible in most of the sites.

Thanks for That post raveson I was beginning to think I had the only american built !! We gotta hook up at the rally and complain to each other about how mean those OTHER guys are to us orphans LOL

[Bob]

Jeol, I go to the Prevost pneumatic and blow that up to get the detail. If you highlight the lines from the solenoid stack to the 5 ports you will see with the key off the 5 port goes to “neutral” and air is blocked in all directions.

No joy, The worm gear is metal and has no roll pin or set screw.

I examined another window with the same configuration quite a bit the other day and it has no pin or screw in fact it appears as if the worm gear is glued in place on the shaft due to seeing what appears to be glue oozed out on the top and bottom of the worm gear at the shaft. So if the worm gear is glued then I should be able to re-glue the worm gear to the shaft and be good to go.

I was able to obtain a new radiator cap for the aqua hot from a parts store.

As far as the links to docs I have not been able to get a search to find what I need and I don’t have access to the parts portion. I’ll keep trying to get prevost/volvo support to help me with that.

[Bob]

I’ll add another vote for OTR and cruise air maintenance – what to look for BEFORE they go out of service.

A spare parts list: some are NICE to have, some are REQUIRED – those are the ones that wil stop you on the side of the road – but are easy enough to replace roadside to get going again. Hearing those members who have been unfortunate to experience a full-stop problem and the part(s) that would have got them going again.

Tom I can’t find the lens or the bulbs on the suppliers web site. I am must be navigating in the wrong direction? Rick

Thanks to you Tom and Jon for all your help great site …. Happy New year!!!!!!

We store our bus a few miles away under cover but without power. I turn off all battery switches, 12/24V chassis and 24V inverter batteries. There are still some direct loads (DDEC and alarm) but the batteries handle those for several weeks. Every three weeks or so I charge up the batteries and exercise all the systems. I winterize the bus before freezing temps hit and de-winterize just before we head south. This has worked well for 18mo. Just another option.

You’re right Bob, only good news so far, in chasing aux leaks, I have come across several fittings leaking on the brake air. Now, my brake air holds for days!!!

If I could only get the aux leaks done, and figure out the dropping rear. Just went out there and it’s already dropped 1/2 inch in 2 hours, with the tag raised!

I drove my 2006 Marathon from Key West, FLA to Fairbanks, Alaska and 40,000 plus miles in between. I covered that distance in about 16 months. When making passage we found MOST not all Walmarts a great and secure overnight stay. We also stayed on MANY fiords in Alaska and seaside pullovers along the ENTIRE WEST USA coast!!! Consistently when we Found an adjoining Sam’s club we enjoyed staying there because they close for business early and opened a little later. This kept th GAWKERS away. A word of caution…ALWAYS keep your outside compartments and toad locked down. Also check your hitch every morning before leaving! Heard many stories of malicious activities with hitches.Our toad was secured with locks so we didn’t have much trouble.Many rest areas can be pretty dangerous and filthy. We always found the MAJOR north FLA rest areas along RTE 10 a safe bet.

Bob.

I think the auto tag lift or air dump was no longer on coaches of Jerry’s vintage. But any time the tag is lifted, part of the system logic is to disable the tag axle brakes and I think that has been and continues to be on all coaches.

[Bob]

Robert, that was a test to see if anyone was awake. Looks like it us Volunteers only.

[Bob]

Exactly.

Please do this specifically. Make sure the HWH is not functioning. I don’t know the HWH system or how it relates to our leveling systems, but we do not want it working behind the scenes.

Start the coach.

Using the level low controls bring the bus up to the drive height as a starting point.

Lift the tag axle and leave it up from this point until the duration of the test

Using the level low controls manually raise the left and right rear to the maximum extent.You may have to have the compressor cycle on and off a few times at each side to insure you have all the air pressure you can get into the drive axle air bags. The tag axle air bags will be deflated.

Turn off the key. Measure the height at the rear, each side.

Here’s what we will learn. The three port valves on each side of the coach between the tag and drive axles should have closed the path between the drive axle air bags and the tag on each side. If they are both leak free the rear of the bus should not drop. After time the coach is going to settle or not. That is what we want to find out. What has been done is you have taken the cross connection between the left and right sides of the coach out and there is no way I can see possible for both sides to simultaneously drop.

Prior to lifting the tag axle both three port Norgrens were only opening the path for air between the drive and tag axles and the only way I can imagine at this point that the rear would drop is if they were both receiving some pressure from the tag lift pilot circuit and bleeding air out of each tag. or equally obscure is if they both had a leak of the same size. That is so remote a possibility I cannot see it being possible.

Hector……if you are out there have you any thoughts on this?

[Bob]

I did my hole coach with DOT comp fittings it’s worth it , and installed ball valves on all acc lines to isolate leaks !!!!

[Bob]

yes, it’s an “odd” hose with the curve, different sized ends and it not being a coolant hose, they charge a premium (made me feel like I was working with HRC ordering parts for my GP race bike again). Nixon was great. Had me the part the next morning and I didn’t even ask for them to overnight it.

As I mentioned, NAPA had a hose that was the same dimensions and shape, by I was worried as it was a coolant hose and not specifically for dealing with diesel turbo/intake application. Would have been much cheaper, but I didn’t want to take the chance of failure.
