My 17 Marathon has a governor set at 80 per Prevost. However going down a long Mtn pass, I have gone over 80. The retarder did not kick in until I engaged it.

[Jerry]

Thanks for the response Prevost Service, much appreciated here on PC…

Jeff and all,

We used the Superior gear box with 1″ OD shaft to replace the Boston gearboxes that were failing regularly. The Superior was rated for a higher input horsepower and would handle this better. In Catbase under page Prevost XL 0525-02 They list gearboxes and refer you to section 0525-99 for gearbox #052212 and IS 97122 (Instruction Sheet)

Pres,

I’m happy to shoot some pictures for you . We have the same generator so maybe they will be helpful. In addition to what everyone has suggested the power and water lines to the remote radiator have to have slack to extend. It may be Friday before I can do the pictures. If that’s not soon enough to help let me know and I will try to reschedule some things.

[Jerry]

Charles, you have a Classic which means you have three 8D batteries. With phantom loads, the refrigerator running, the TV circuit on, using some lights after the generator shuts down for the night new batteries might get you 8 hours, but as they age you will not get that performance.

The Amana refrigerators were energy hogs. I don’t know if you have upgraded but every little current draw adds to the load and even an Elegant lady with its 4 batteries sometimes is lucky to go 8 hours unless you really cut down on every load possible.

[Jerry]

I am very interested in making a slide..

This is crazy.

Pres

[Jerry]

Cannot read amps but everthing is off in bus.

[Jerry]

Thanks for the guidance… I plan to have a mechanic do this job. I will have a proper lift or fork lift available. It was so stupid for the installation to have been done like this. The rest of the coach has been so great….

Best,

Pres

[Jerry]

That’s one downside to the way CC did their gens instead of a slide out. It will likely have to come out and best option is to have a forklift available. I know over the years I’ve heard removing the gen isn’t that big a deal, so hope it goes easy for you.

[Jerry]

So I need to find a dealer that has a module to hook to my Gen control box that will send the info to my phone that I need. Thanks for your help Jeff.

This is a report on the Pressure Pro Pulse system I installed recently.

I made my first trip with them last weekend, and here are my findings:

Very easy to install, the hardest part was getting to the inside drives, which, I removed the outside drive tires to be able to get to the valve stem, and make sure the stem is pointed in the right direction (pointed in the center of the outside wheel). The easiest way IMO is to drive the bus up on 2 2×12 boards with the inside drive, then you can remove the outside wheel, without jacks etc. Being an old trucker, I always put my outside wheel valve stem 180 degrees from the inside wheel. I did make a PVC tool to install and remove the sensor without removing the outside tire/wheel.

The next feature I really liked is……NOT HAVING TO GO AROUND AND CHECK PRESSURES ALL THE TIME WITH A TIRE GUAGE. Just push a button, and it shows you the pressure instantly.

I also installed them on my toad, and my Stacker, the 6 tires on the trailer, I can now see the pressures as well.

The day of my trip started out Hot, humid, and 96 degrees. I was also pulling my stacker. about 2 hours into the trip, I got a “HIGH TEMP” alert, which started beeping, definitely got my attention. But, I had lowered the factory setting on the alert from 200 degrees down to 190. My drive pressures were 120psi cold starting out, so you can see how much they rise on a hot day.

I called Tom, and we decided I should stop and take the temp of the inside drive with my heat gun just to be sure, it was 152, which triggered the sensor to read 190, the outside tire was 140. Being that the tire beside it was cooler and the same pressure within 1 pound, we decided that it wasn’t a dragging brake, or hot bearing.

IMO I think the right side drives were a little higher in pressure and temp because of the crown of the 2 lane road I was on, so leaning that way adds a little more weight.

I changed my alert to 200 degrees…….a couple of hours later, going up some very steep mountains, that same sensor caused another alert. The outside stayed cool. I stopped and even shot my temp gun on the inside wheel, and it was only 165.

So, my plan is to change out that sensor with one off the Toad to verify whats going on.

I still like the system so far, and am pleased with how it works.

Today a short trip up town to drop off my trailer, and below is what it looks like. 85 degrees today. Same sensor higher.

The sensors read in 40 degree increments, once I change out the high one, I should know whether the bus has a problem, or the sensor, I’m thinking maybe a bad sensor.

I’ll post the finding on that later.

[Jerry]

I’ll stay out of the middle with you and Jon, but my money is on a bad monitor. Common problem, I’ve replaced one on almost every bus I’ve had.

Buddy – I have 3 Equalizers, 2 for the 12/24 house and 1 for the engine.

[Jerry]

Hey Jon, hope all is well with you and Di.

Why would a house system have and equalizer, for coaches that have both voltages for the house systems ?

[Jerry]

Well done Jon.

[Jerry]

I had the oportunity to look at this excellent video. Ken and Andy did a great job on providing information about technology for future coaches.
