Product Description
Fin-Nor EM311-01 Pinion Gear Assembly
Restore the smooth cranking power and reliable gear mesh of your high-performance saltwater reel with the Fin-Nor EM311-01 Pinion Gear Assembly. This genuine OEM component is the critical link between your main drive gear and the spool shaft. Precision-machined from hardened stainless steel, this pinion gear is designed to withstand the immense torque and pressure of fighting large pelagic species.
As a "Pinion Assembly," this part typically includes the pinion gear pressed with a specialized bearing or bushing, ensuring perfect alignment within the reel's side plate. If you are experiencing a "grinding" sensation, slippage under load, or if your reel has seized after saltwater intrusion, replacing the pinion assembly is often the only way to restore factory performance.
