1180843 (5-113H Main Gear)

Genuine Penn Main Gear (part 1180843) — the primary drive gear that meshes with the pinion gear to transfer cranking power from the handle to the spool, delivering the torque needed to retrieve line and fight fish. The main gear is the largest and most critical gear in the reel’s drivetrain, and worn or stripped teeth cause grinding, skipping, and complete loss of cranking power.
