10KL0  (BNT1779  Worm Shaft)

Genuine Shimano Worm Shaft (part #10KL0, BNT1779) — the worm shaft is the helically grooved rod that drives the levelwind yoke back and forth across the spool, ensuring your line lays evenly during retrieve. A worn, bent, or corroded worm shaft causes uneven line distribution, bunching on one side of the spool, and can lead to casting problems and line tangles. Cross-references with Shimano part numbers 10KL0 and BNT1779. OEM replacement ensures perfect fit and factory performance.
