For those who are bus fanatics as most of us are likely to be, Box Car Okie has one of the sweetest Eagles around and I can’t wait to see some of his handiwork. Rumor has it he may show up at the OKC rally the end of September.

Cruise through his blog and you will see various pictures of his Eagle.

Good idea John, I never know when my grill propane tank at home is
about to go dry, leaving me with unkind words from the better half.

Far too many uses to list here, but what you saw the trucker doing was likely checking his tires (one tire hotter than the others could be an indication of loss of pressure), his wheel bearings or for brake drag, all of which are usually equal or close to equal with the odd reading indicative of a problem.

Get in the habit of using it to measure temps at the center of the tire treads to check tires, the wheels near the hubs to check bearings or brakes and soon you will learn what is normal so when a temp is out of what you know to be normal you can check further.

Inside the house you can check you AC supply and return temps. A 15 to 20 degree spread is probably normal so when the temps are closer you know you have a problem or the beginning of one.

You will find many uses such as checking the temps of your steaks to verifying the wine is chilled to the perfect temp for serving. Good investment.

Come on Tom and Jon….How about posting some pictures from your rally???

[Bob]

If it is not raining too hard tomorrow, I plan to start the bus and see if I can spot the leak for certain. Where exactly is the can that you think may have the busted diaphram? You say I should be able to see it?

Thanks,

DKO

Is this a great site or what ?

Hey Jon, while we are on the subject of horsepower, my engine id plate says a 12.7 LTR engine. I was told this was a 500 HP engine. Would a 12.7 be 500 ?

Buddy,

Those folks picking on me just don’t even rise to the level of minor irritation. They have to bring their “A” game if they are going to wipe the grin off our faces. Now that I have 2 coaches of different generations I feel entitled to argue and debate with the best of them.

I have a 98 and mine is just like Greg’s

[Bob]

Bob mine is a “91 with a rotor knob, pointing to the rear is the drive position, left is left and right is right side and to the front is front air bags. Greg

[Bob]

Thanks so much Mark… that’s the “shortcut” I was hoping for.

The buzz word if you call Prevost is “reverse tag logic.”

[Bob]

Assuing you have “level low” what you describe is normal because once aux. system pressure drops below a certain value (30 to 35 PSI) the air in the tag axle dumps because the 3 port valve between the tag and drive axles requires that pressure to keep the valve from exhausting tag axle air bags.

There are a couple of options available. The first and best is to correct the aux system leaks causing the air pressure to drop. That is easier said than done. A second option is to revise the air circuitry a retrofit offered by Prevost. That revision has a fairly expensive cost but does eliminate the need to maintain aux system pressure. Any Prevost service center can probably give you a quote.
