Gear Tension Relief

When the displacement cylinder pistons are in their upmost position, each motor has prevailing torque due to the force necessary to ensure each piston is held firmly at the top of its travel. This torque results in "gear tension," or force on each gear that makes motor pack separation difficult. To avoid injury, or damage to the gears, the GEAR TENSION RELIEF function briefly reverses each motor to eliminate the prevailing torque. Always perform the GEAR TENSION RELIEF function prior to removing the hydraulic modulator or motor pack from the vehicle.
