10DVY  (RD19808  Worm Shaft)

Genuine Shimano worm shaft (part #RD19808, SKU 10DVY) — the helical drive component inside your spinning reel's oscillation mechanism that moves the spool up and down during retrieve, producing an even, level line lay. A worn or bent worm shaft leads to uneven line distribution, bunching on one side of the spool, and reduced casting distance. Cross-references with Shimano part number RD19808. OEM replacement restores factory-precise oscillation and smooth, tangle-free line management.
