C13 New compressor, air dryer, and governor

The ADIS dryer should only use the blue capped governor from Bendix which is non-adjustable. Installing a adjustable one will really screw things up and it will never cut out right.

 

put a cap on the main big line that goes to the air tank. start the truck. it should almost immediately start relieving out the safety valve on the compressor. if it doesn't do that your compressor is unserviceable. if it does your compressor is fine and the problem is either in the pneumatic plumbing or a leaking discharge hose which is pretty common.

pays to get someone to help with dead heading the compressor as it is best to run it for as little time as possible. the safety valve will protect the compressor.

if it doesn't relieve from the safety valve when dead headed there is a fault with the compressor. either there is a big hole in the piston or the unloader valves are jammed open

 

Your suction hose/intake hose upper piece looks pretty flimsy. It isn't collapsing or sucking shut? Also, ones on KCB C13 have a storage tank with check valve for proper Reed valve operation.

 

have u dead headed the compressor yet?
