More replacing on bus

[timvasqz]

What caused the accompressor to go? wonder if there is an ubstruction in the oil
path to/from the crankcase of the compressor ? the compressors crankcase is not
vented so a kink in the line either way will stop the lubeoil .?????????????

Truck. One swapout, no problem. Replaced the second one and the problems
started. Seems the old one has a set screw on the bottom that adjusts the
pressure on the tag air bag. The new one didn't. Put the new one in and watched
the air bag gauge almost go to 150 lbs!

shape, so put it back in the system. Pressure dropped to 35psi, like it should
be.
