mci-9 wont air-up

[Busnut83]

The dryer is leaking air in the front... Problem is i have a dirt drive-way and there is not enough room to get under the bus... Help ,,, what can I do ??

Probably a good time to build a set of ramps.

Mine are made out of 2 X12 's screwed and bolted together.

They travel with me in the back bay.

There also great for getting the bus up if you get a flat, so you can get the jack underneath.

Make them a little long as these things don't climb up them like a car or truck.

The drain valve is stuck. Maybe you can turn the wheels to the right far enough to reach in there
and give it a sharp pop with a small hammer ( the tip that hangs down ) ( Not hard or you could break it! )

Sometimes it will pop it loose so that you can air up.....

There is a trick to fix this- take a 1" x 2" or so peice of wood cut it about 4' long. Just start a 2" sheetrock screw (or similar screw) and leave 1-1/2" sticking up (head up).
  Take da tool (was da stick) and reach under the bus with the engine running and hit the purge valve with the screw. The valve gets rust and crud and stick in the open position. Tapping with the screw just knocks it back in.
I hope I explained that well enough to help. I discarded my stick when I rebuilt my dryer and purge valve. I had to use it several times before rebuilding the dryer-

You can also get some pneumatic lube and remove the air inlet to the compressor and squirt some in the intake.
Sometimes this will free the sticky valves in the compressor.

Ditto, Cracker!

I built a set of 2X10 ramps and carried them in my MC9 everywhere I went. They also help if you blow a tag axle tire and need to get it up to put the chain on.
