The Ghost Gunner 3 uses a belt to drive the spindle. Over time the belt can wear out.

Replacing the spindle-motor drive belt:

Tools: 8mm wrench, 4mm allen & 2mm allen. 

• Unplug power and USB cables.

• Vacuum as best as possible and turn your machine upside down.

• Move the gantry center and spindle to the front by getting a good grip on the motor and using a bit of force to slowly move it. 

• Loosen 4 nuts on BLDC motor using 8mm socket and 4mm allen.

• There are slots in the motor mount that allow the motor to slide closer to the spindle for belt installation. A few turns should be sufficient to loosen the bolts so the BLDC motor can slide closer to the spindle.

• Loosen 2 set screws on the spindle pulley using a 2mm allen enough so it can come off.  

• Work the new belt in and reattach the pulley on the spindle.  Belt should be loose.

• Use a wrench to push the motor away from the spindle to achieve adequate belt tension and tighten down 4 motor mount bolts.

Belt installation is complete.
