Another compressor problem

[Gregory OConnor]

John, if the belt is tight and the compressor is spinning check the
key in the pully shaft???? you can also check to see if the
compressor head gets hot???

If it is a leak it must be big. you can not hear it because it wont
build enough pressure to hiss and while the cat is running there is
too much noise to hear a big leak hiss. I would hook the aux air up
to a remote shop compressor and look for a leak that way. build a
male to mail fitting for a remote compressor line's female end and
try and build up the tanks in the bus that way?????? I have had
valves hang up that just needed a jolt of reverse air to get thm
free.

It could also be that there is a blockage in the compressor output
line to the first tank
