Internal??? air leak ft suspension

FYI , our bus had a governor that cycled between 110 and 130 psi when we got it and was never a problem. I have seen certain ones that are designed for those pressures. But I would guess the most common governor cycles between 100 and 120.

138 is to high never seen one that high have it checked out Mark maybe the gauge is not right on

I see the confusion on my part now.
The gauge markings are 20, 60, 100, 140 and 180 psi…. which is a big range between markings. Halfway between 100 and 140 would be 120 psi and my reading is above that. From the distance from 100 psi to 140 psi, it must be about 128-130 psi (it fluctuates a little).

Prevost has allowed up to 130 if I remember correctly. The best bet is to check their service manual for your coach and see if that holds true. But like others, if it is in fact almost 140 it is too high.

I’m not losing any air now with the new coupler replacement. The compressor ‘might’ come on once a day if I use the air doors, otherwise, quiet as a mouse.
My air gauge reading seems to hover around 130 or so, never going close to 140.
I coasted today to 85 mph for a couple of minutes….. nice downhill in New Mexico. Wow, the coach is so smooth and solid.

You do know that your tires are rated for 75 mph max speed, right? Wouldn’t want you to wind up blowing one out and ruining that nice bus….

Mark,
I knew someone was going to say that. The tires are new, I just wanted to feel the speed for a few seconds. It was all over in less than 2 minutes.

The coach air system keeps the coach level and non-swaying in heavy winds.
Well, today was a 55 mph day for over 350 miles. The wind was horrendous…. 60 mph plus wind gusts.
But, the advantage was that it was pushing us east. So, for two days we covered over 750 miles, I have averaged 9 mpg on the dash computer. At just over 750 miles, the fuel gauge is halfway between 1/2 and 3/4…. I’ll make 850 miles at half a tank easy if tomorrow is like it was today (wind blowing east). Normally, we would be getting 6-7 depending on the terrain.
