Gear Tension Relief Sequence

Gear Tension Relief Sequence


When the displacement cylinder pistons are in their topmost 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 Sequence" briefly reverses each motor to eliminate the prevailing torque.

Always perform the "Gear Tension Relief Sequence" with the scan tool prior to removing the hydraulic modulator-master cylinder assembly from the vehicle.
