10DN0 (RD17607 Main Shaft Assembly)

Genuine Shimano Main Shaft Assembly (part #RD17607, SKU 10DN0) — the central shaft that runs through the reel body and carries the spool, oscillating up and down during retrieve to lay line evenly across the spool face. The main shaft assembly includes the shaft itself along with any integrated bushings, washers, or collars that ensure smooth oscillation. A bent, worn, or corroded main shaft causes uneven line lay, spool wobble, and increased friction that robs cranking power and shortens casting distance.
Cross-references with Shimano part number RD17607. OEM replacement restores precise spool oscillation and the even, tight line lay that maximizes casting performance on Shimano spinning reels.
