INSTALL MOTOR

Holding the motor in the location where it will be mounted, align the herringbone gears by sliding the small gear in or out on the motor shaft so the V-grooves are centered on each other.

Install motor using 3x M3 x 12mm SHCS and 3x M3 washers, taking note of the orientation of the motor wires.

Push the gears together while you tighten the bolts to make sure the contact is tight.

Tighten the set screw on the small herring bone gear.

Are the motor wires oriented correctly?

Are the V-grooves of the gears aligned?

Is there any back-lash in the gears? Can you spin the large gear for several rotations?
