10LX0  (RD3690  Pinion Gear)

Genuine Shimano Pinion Gear (part #10LX0) — the vertically oriented gear that meshes with the main drive gear to convert handle cranking into rotor rotation. Worn pinion gear teeth result in rough retrieve, grinding sensations, and reduced cranking power under load. Cross-references with Shimano part number RD3690. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
