Drive Bushing

The MSD Ignition Drive Bushing (part number MSD17193) is a precision magneto drive component engineered to maintain proper alignment and engagement between the magneto shaft and ignition system drive mechanism. This black plastic bushing is designed for ignition systems that rely on magneto-driven spark generation, where precise mechanical coupling is critical to consistent firing performance across the RPM range.

The bushing's compact dimensions (2.15 × 0.65 × 3 inches) and minimal weight of 0.01 lbs allow for seamless integration into existing MSD Ignition systems without adding mechanical load. The plastic construction provides electrical isolation while maintaining the dimensional tolerances necessary for smooth magneto engagement. This component addresses a common point of wear in magneto ignition assemblies, where the drive interface experiences rotational stress and mechanical friction during extended operation. Proper bushing condition ensures that ignition timing remains stable and that magneto drive forces are transmitted efficiently without slippage or misalignment.

This replacement bushing is essential for technicians and enthusiasts maintaining or rebuilding magneto-equipped ignition systems, particularly in applications where original equipment has experienced wear. Whether servicing vintage automotive systems, marine installations, or small-engine applications that depend on magneto ignition, this MSD component ensures the drive coupling functions within factory specifications. The part ships as a single unit, allowing for targeted replacement without requiring complete magneto or drive assembly disassembly.

MSD Ignition manufactures OEM and replacement ignition components recognized for precision engineering and material consistency. Sourcing verified MSD parts ensures compatibility with systems originally designed around MSD specifications and performance standards.
