This step is important to prevent personal injury!!!
Most regulators use a large clockspring to counterbalance the arm and gear. This spring can exert up to 40 pounds of force in some applications. When the motor is removed from the regulator, the arms will try to rotate in one direction while the chassis goes in the opposite direction. Just like a giant pair of spring loaded scissors!!!
The regulator arm and gear must be locked to the chassis to prevent this from happening. There are several different ways that will work satisfactorily. This is the one that we prefer.
The regulator and motor assembly is clamped in a bench vise. A 1/4 inch hole is drilled through the gear and chassis in a clear flat spot.
A 1/4 inch bolt is then inserted in the hole and a nut finger tightened to it. This will prevent the chassis and arms from moving when the motor is removed.
