Genuine Shimano Pinion Gear (part #109YD, BNT1380) — the pinion gear is a core component of your reel's gear system, meshing directly with the main drive gear to convert handle rotation into spool movement. A worn or damaged pinion gear leads to rough retrieves, slipping under load, and eventual gear failure. Cross-references with Shimano part numbers 109YD and BNT1380. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
