Why this part matters Direct replacement fit: Matches multiple original part numbers so it can be used as a dropin replacement for compatible starter applications. Restores starter engagement: The 10tooth pinion and spline count ensure correct meshing with ring gears when the starter engages, minimizing wear and preventing failed starts. Proper orientation and voltage: Designed for clockwise rotation and 12 volt systems to match standard starter motor configurations. Benefits for the user Reduces downtime: a worn or damaged starter drive to get engines back into service quickly. Simplifies inventory: One unit covers several OEM part numbers, reducing the number of different spares required. Predictable performance: Specified pinion dimensions and tooth count help maintain consistent engagement and retraction behavior. Applications and use scenarios Fleet maintenance: Keep as a spare for routine starter repairs on 12 volt vehicles and equipment that use compatible part numbers. Workshop replacement: Ideal for technicians rebuilding starter assemblies where the original drive is damaged or worn. Equipment refurbishment: Use when restoring engines and mechanical systems that require a clockwise starter drive with a 40 mm pinion and 10 teeth. Installation notes Confirm compatibility by matching the vehicle or equipment part number to the list provided before installation. Observe correct rotation and electrical system voltage when installing to avoid improper operation. Weight and dimensions should be considered when handling and installing in confined or mounted starter assemblies. This starter drive assembly provides a specificationmatched replacement for compatible 12 volt starter systems requiring a clockwise rotating, 10tooth pinion with a 40 mm outer diameter.
