10M46 (RD13583 Pinion Gear)

Genuine Shimano Pinion Gear (part #RD13583, SKU 10M46) — the vertically oriented gear that meshes with the drive gear and transfers rotational force to the rotor assembly on Shimano spinning reels. The pinion gear sits at the intersection of the gear train and the main shaft, making it one of the most load-bearing components in the reel. Worn pinion gear teeth cause clicking, rough retrieve, or catastrophic gear mesh failure under heavy drag pressure.
Cross-references with Shimano part number RD13583. OEM replacement guarantees precise tooth engagement with the drive gear, restoring the smooth, powerful retrieve Shimano spinning reels are known for.
