Gear Case Assembly
The gear case houses the bevel gears responsible for transferring vertical shaft rotation to horizontal head rotation. Frequent impact or high-load operation can strip the gear teeth or shear the output shaft, resulting in a motor that runs without spinning the spool. This assembly is the standard surgical replacement for mechanical rotational failure.

Switch Trigger Assembly
If the motor does not engage at all when the lock-off and trigger are depressed, the internal microswitch or physical trigger linkage has likely failed. This breaks the electrical signal to the motor controller, preventing any rotational output.
