DEFECT #1 - SERVICE BRAKES, AIR:SUPPLY:HOSES, LINES/PIPING, AND FITTINGS
Posted on: 1995-09-27
Description
Air system blockage in the air dryer occurs degrading the moisture removing capabilities of the dryer when the vehicle is operated in a cold environment and moisture accumulates and freezes in the air dryer or in the line between the dryer and the air system reservoir. The air dryer can become overpressurized causing the air dryer cartridge to separate from the mounting base.
Consequence
If the air dryer separates from the base, the cartridgecan separate sufficiently enough to cause personal injury or property damage.
Corrective Action
Dealers will equip air systems with a pressure relief valve to be located between the compressor and the air dryer. This pressure relief valve is intended to vent if excessive pressure develops in the air dryer.
