Additional Notes
The main differences between original and aftermarket parts lie in winding material, gear heat treatment, and sealing performance. Aftermarket parts are more affordable, but original parts offer better long-term reliability and lower failure rates for heavy-duty construction use.
Common failure symptoms include weak cranking, free-spinning, and gear engagement failure, which are typically caused by worn brushes, faulty solenoid switches, or damaged gears. Replacing the entire assembly is the most straightforward solution.
