Deep Reduction Air System (with Dash Mounted Valve)

In addition to the components of the range air system, the deep reduction air system utilizes a reduction cylinder and a separate dash mounted deep reduction valve. Air is supplied to the system at the air supply port (1) by the vehicle's air system. The air filter (2) removes foreign matter from the air then allows it to pass through the air regulator (3) where the pressure is adjusted for 58 to 63 PSI. From there the air passes through the supply air hose (4) to the slave valve supply port (5) through the supply air hose (6) to the deep reduction valve (7). Depending upon the position of the deep reduction valve lever, if air passes through the air hose (8) connected to the reduction cylinder center port (9) then the deep reduction gearing is disengaged. If there is no air, the constant air from the air filter/regulator assembly (10) moves the reduction piston rearward to engage deep reduction gearing.
