tank locations MC-5C

[bevans6]

I'm busy getting familiar with my new bus.  Can someone summarize the main air tank locations for me?  I want to make sure I'm draining the wet tank in particular.  I was told the wet tank is behind the side panel under the drivers window?
Also - how long should the bus maintain air pressure?  the dash gauge falls to 50 or 60 pounds overnight.  It doesn't fall when it's pumped up, engine off,a and I do a service brake application.

Thanks again for helping a newbie.

I would suspect the tank under the driver is the auxiliary.

Do you have a pair up behind the front axle either side of the centre line, one in close proximity of the rear axle, and one under the driver?

I'd suspect the wet tank is one of the ones centre line at the front axle.

However, you need the schematic from the maintenance manual, for your exact unit number, there were a lot of variations in those years as FMVSS 121 took hold, and various states had their own regulations for coach plumbing. Just any schematic will not suffice. The wet tank may be the back, may be the front, depending on vintage.

happy coaching!

There are three air tanks.
Under the drivers seat
between the front wheels
the second bay from the front drivers side (on the right bottom) you will see a little door abut 3" x 5"
Thats where the voltage regulator is also.
let me know if you need anything else

Mine does the same thing, and it is a slight leak from the second rear baggage comp driver's side. In a quiet building, 1/2 hour after shutdown, it is like listening to the dinosaurs snore.

It is on my list, but have not gotten to it, but getting closer to top of list.

Good Luck and Enjoy

Found them all, drained them all, got most from the discharge muffler, a fair bit from the wet tank, and all the others were dry.  thanks, everyone!

Made run-up blocks to run the front wheels onto so I could see under the front to find the tanks.  Found the energency fill valve, took the spare tire and cover out to have a look around.  Slowly getting to know the lady!
