Does anyone know

1. what the wet weight of an allready converted bus is, say an MCI-9 model

2. what the maximum GVWR is?

3. how much can it tow, the GCWR?

Just looking for rough figures.

And is there a great or small difference between these figures with similar bus makers, like Prevost, Eagle...?

Thanks
George

I guess my question is:

how close are the conversions to their maximum carry capacity and how much can they tow?

George -

According to the data plate on an MC-9, with 12R22.5 tires:

GVWR = 36,500 lbs

Bus manufacturers generally do not publish GCWR numbers.

Empty MC-9 shell is about 26-27,000 lbs. before adding back in all the conversion stuff.

My MC7 converted, full of fuel, but no water in the tanks, tips the scales at 30,100 lbs. (2/3 of that is on the rears).

I have a MCI 9 that will not build up air pressure above 70lbs. I have already replace the air governork,check for leaks,and clean and lubed the plunger valve to no avail. Any suggestions? Does anyone know where I can find the schematic for the air system?

thanks,

Hello CC.

Quick guess, you have a leak in the accessories or the air suspension.

The pressure protection valve is allowing 70lbs of air to the brakes, then opens to supply the rest. If you air it up as far as it will go, search around for the noise, if neccessary have someone shut off the coach to hear at the rear, but the leak won't last long after shut down, you may have to run it again a few times as you move around. Not enough time for you to do it by yourself, if you aren't getting air over 70.

Beware, for my money, you'll find more than one leak. Don't be fooled thinking there is only one.

You need a maintenance manual for that bus, available from many sources, as well as MCI.

happy coaching!

Cavalier, put the bus on shop air and turn off the main engine so you can find the leaks faster. The mci 9 maintenance manual has several schematics of the air system. but my experience has been that you know that a part should be there, but it doesn't do a good job of telling you what it looks like, or where exactly it is. so i've spent a couple of days crawling around looking for this or that.

check to see if there's a valve plumbed into your bus on the passenger side rear compartment, look on the foward wheelwell. If not you can put air into the bus using the emergency fill,
located in drivers side front compartment of
the bus, usually mounted on the rear wall. This is the compartment that your washer fluid is in, located directly below the electrical panel on
the outside drivers side.

Check the air dryer
