Key specifications Part numbers: 2280001132, 8970489662, 1280001100, 2280001130, 8970489663, 2280001131, 2280001133, 8941702051, 686696129302, 2280001133, 8970489660, 8970489661, 2280001131, 2280001132, 8970489663, 2280001130, 1280001100 Number of teeth: 9 Rotation: Clockwise Starter type: OSGR Voltage: 12 V Why this part matters Restores starter engagement: The correct tooth count and rotation direction ensure proper meshing with the flywheel ring gear, reducing start failures caused by worn or damaged pinions. Direct replacement fit: Supplied to match the referenced part numbers for straightforward swapin replacement without modification. Consistent electrical compatibility: Built for standard 12 volt starter systems common in automotive and equipment applications. Features and performance Precision tooth geometry to promote smooth engagement and reduce gear wear. Engineered for OSGR style starter mechanisms with clockwise rotation. Suited to applications that require a 9 tooth pinion and 12 volt operation. Designed for reliable mechanical engagement under repeated start cycles. Typical applications a worn or damaged starter drive in passenger vehicles or light commercial equipment that use 12 volt, clockwise OSGR starters. Fleet maintenance: swap a failed pinion during routine starter rebuilds to restore dependable starting across multiple units. Small engine and equipment service where the starter drive is the source of grinding, slipping, or intermittent starting. Installation notes Confirm the part number and physical tooth count before installation to ensure compatibility. Inspect flywheel ring gear and starter housing for wear; or other worn components as needed to prevent premature reoccurrence. Install in correct rotation orientation consistent with OSGR starter design and 12 V system requirements. What you get A direct replacement starter drive matching the listed part numbers and the specified properties: 9 teeth, clockwise rotation, OSGR starter type, 12 volt operation.
