Airing up an MC8

[prevost82]

The more important time is; after the bus suspension is aired up, how long does it take to get from 90 to 120 psi. I think it's to be no more than 1 minute @ 1200 rpm.

The 90 to 120 took less than 2 minutes but more than a minute.

This of course is the reason for my question in an earlier post -- what is the cost of getting rid of the air beams and going to the rolling lobe air bags.  Not something I want to do myself.

I really appreciate all the responses it gives me a place to start.

I am sure there are numerous small air leaks in all the air operated stuff.

I will begin a program to chase them down.

After working on the air leaks and not really finding as many or as large as I thought I would I have an additional question.

Would the altitude make a difference in how long it takes to air up.

I know it makes a difference in fuel mixtures and other operation of the coach but would it take longer to air up at a higher altitude??

Just a thought I had.

It is time consuming.  I have a little sears air compressor on board which I pre fill, before engine start.
