Check your extruder motor if it has a removable gear. If its pressed on (no set-screws/not removable) then you will need to replace the stepper motor in order to install the kit.

Preparation

• Print a fan shroud if your printer's stock shroud will not fit. Check Compatibility tab above.

• Verify your stepper motor has a removable gear. If not, then you will need a new stepper motor. We recommend the Creality 42-34.
