RTL-xx710 Model Range Cylinder Assembly

LO Range - When the shift lever is moved laterally from 7th to 6th gear, air is supplied to the range cylinder housing port (1), moving the piston rearward, engaging LO range gearing (2).

HI Range - When the shift lever is moved laterally from 6th to 7th gear, no air is supplied to the range cylinder housing port (1), moving the piston forward, engaging HI range gearing (2).

Spool Valve

The spool valve components shown are part of a self-contained valve assembly, part number A-6864.

The spool valve piston travel is approximately 1/2". When filtered air is supplied from the 4303110 valve to the valve spool right side (1), constant air from the filter/regulator (2) flows through the valve spool and seal plate to the range cylinder piston front side moving the yoke bar rearwards. Air is exhausted from the range cylinder rear (3).

When no filtered air is supplied from the 4303110 valve to the valve spool right side (1), constant air from the filter/regulator (2) flows through the valve spool and seal plate to the range cylinder piston back side moving the yoke bar forward. Air is exhausted from the range cylinder front (3).
