Z truck motor pack gears adjustment

[fishrepair]

In one of the pdf repair videos that I just viewed, it said that if the z track was rough or grinding when it was moved up and down, that the z motor pack gears might need adjusting. I can't find anything about that any where. How do you adjust the gears? The gear pack is some what loose on the rear of the motor and if I hold it tight against the z truck the whole thing moves up and down smoothly.

The gear box is attached to the z motor with I think 2 or 3 screws. I've had mine loosen up before when I did the zpak upgrade. I put some blue loc tite on the screws when putting it back together.

You will need to remove the zmotor assembley to get to the gear box. Follow the z motor replacement pdf for the removal...

Thank you Mr. Harris. I disassembled it and there was 2 screws and both were loose. tightened them, assembled the gearbox to z motor and it worked perfectly.
