Additional information

This worm gear, part number 5-7180, meshes with a worm shaft so rotational motion from the control crank transfers smoothly to the driven mechanism, such as chute rotation or other indexed movement. Proper gear engagement helps ensure predictable, controlled motion.

If the mechanism is difficult to turn, slips, binds, or does not hold position when adjusted, the worm gear may be worn, chipped, or misaligned. Uneven wear or visible damage to the teeth can also affect how well the gear operates.

Before starting the repair, disconnect the spark plug wire or power source to prevent accidental starting. Align the worm gear correctly with its mating parts during installation so it meshes smoothly and operates without binding.
