613 and 6613, A-5015 Roadranger Valve

Intermediate Shift Cylinder Assembly 613 and 6613, A-5015 Roadranger Valve

Deep Reduction - With the Roadranger valve lever in the up position, air is supplied to the Intermediate cylinder cover port (1), moving the piston forward, engaging deep reduction gearing (2).

LO or HI Range - With the Roadranger valve lever in the down position, no air is supplied to the Intermediate cylinder cover port (1). The constant air from the air filter/regulator assembly (2) moves the piston rearward (3), disengaging deep reduction gearing.

Insert Valve

The insert valve is a self-contained 1-13/16" valve assembly located in the intermediate cylinder cover. It cannot be disassembled except for the three (3) O-rings on the outer diameter. The O-rings provide a stationary seal and do not move in the cylinder.

Insert valve piston travel is only 1/32". When air is applied to the valve piston top side through the signal line, constant air supplied from the air filter/regulator passes freely through the insert valve and to the cylinder piston backside, moving the yoke bar forward to engage deep reduction gearing.

When no air is applied to the valve piston top side, the piston moves up to cut off air supplied to the cylinder piston backside. This air is exhausted out the cover back center bore, when constant air supplied from the cylinder is directed to the cylinder piston front side, the yoke bar moves rearward to disengage deep reduction gearing.
