that connects the air compressor discharge line to the air dryer inlet fitting. Remove the air dryer delivery port fitting (OUT 21). Using any necessary fittings, install a Tee fitting in the air dryer delivery port. To one side of the Tee fitting install the line removed from the air dryer delivery port, to the opposite side of the Tee fitting install the line removed from the air dryer inlet port. This procedure will allow the integral governor to continue to regulate the air brake system pressure properly.

Note: This is a temporary bypass of the air dryer. Full repair of the unit must be carried out at the earliest opportunity. Excessive vehicle operation with the air dryer bypassed may damage oil sensitive components such as an automated manual transmission or the emission system. With the air dryer removed from the system, contaminants will be entering the air brake system. Reservoirs will need to be manually drained daily until the repairs are completed. At the end of each working day, park the vehicle and slowly drain pressure through the drain valves — leave open to the atmosphere — for several hours, if possible. When repairs are carried out, be sure to check that all reservoirs are emptied of all contaminants.
