10LWZ  (RD3657  Pinion Gear)

Genuine Shimano Pinion Gear (part #10LWZ) — the vertical gear shaft that meshes with the drive gear to transmit handle rotation into rotor spin. A damaged or worn pinion gear produces rough cranking, gear noise, and diminished retrieve power when battling fish. Cross-references with Shimano part number RD3657. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
