Look what my coach has...What the heck is it?
Hello all. While doing some chassis maintenance I discovered some hardware that has baffled me as to what it is, what it does, why I should be proud to have it, and does it require any periodic maintenance. And should other POGgers be jealous if they do not have them?
Pictures below. The items in question are two cylinders, about 4 inches in diameter and 14 inches high. Mounted vertically between the frame and the drive axle assembly just inside the brake cans, one on each side. There are two 1/4 inch hoses connected to a fitting on the bottom, and a 1/2 inch, thick walled hose connected to the top side of each one. They look like air hoses. The brackets these cylinders are mounted on look like they were welded in place by Prevost when the coach was built. You can see the cylinders at the 10 o'clock position of the drive axle.
The bottom has a rubber boot, underneath is a chromed 3/4 inch rod. The whole thing looks like an air adjustable shock absorber like we all used in the 1970's. I have not traced the hoses, they all go into bundles and are hard to trace. No mention of any of this in my Prevost parts or service manual, nor the Marathon paperwork.
Maybe this is some kind of perpetual motion air pump device that extracts energy from bumps in the road and adds the energy to the Detroit Diesel output?
Looking forward to reading your thoughts!
