1 Check method: For the truck equipped with an air
dryer, regularly check accumulated water in the air
reservoir (recommended monthly). When
accumulated water is found in the air reservoir
furthest from the dryer, it indicates that the desiccant
has failed, and the drying cylinder should be
replaced.
2) Replacement method: 1) Unscrew the top nut of
the dryer, remove the old drying cylinder, clean the
connecting bolt and the valve body; 2) uniformly
apply one pass of grease onto the sealing and
matching parts between the new drying cylinder and
the valve body, and apply little thread locker onto the
matching part between the new drying cylinder and
the connecting bolt; 3) Screw the new drying
cylinder onto the valve body to the maximum torque
of 15NM.
