Instructions
The following detailed instructions are presented in the video below and can be displayed by enabling the subtitle/closed captions in the video player.
Proceed with the zoom gear adjustment if there is too much friction between the zoom and motor gear
Loosen the front screw holding the plastic cable tie that covers the jacking screw
Loosen the screw mounted vertically that holds the zoom motor
Tighten the jacking screw, to be able to move the motor away from the zoom
Position the motor gear where it is slightly touching the zoom gear
There are 4 screws attaching the motor gear to the zoom cell gear
The screw at the center is the jacking screw, which pushes the motor gear in and out
Tighten the screw mounted vertically and adjust the height of the motor gear with respect to the zoom gear
Adjust the jacking screw to make the motor gear engage with the zoom gear
The jacking screw should not be forced into the part. It will damage the surface of the zoom assemblyThe goal is to have both the motor and zoom gear rotate smoothly while having a small play between the two gears
The gears might slip if the screws are too looseCover the jacking screw with the zip tie holder
