1081V  (RD16170  Worm Shaft)

Genuine Shimano Worm Shaft (part #1081V, RD16170) — the worm shaft is the precision-threaded rod that drives the oscillating mechanism, moving the spool up and down to distribute line evenly across the spool during retrieves. A worn, bent, or corroded worm shaft causes erratic spool oscillation, uneven line lay, and reduced casting distance. Cross-references with Shimano part numbers 1081V and RD16170. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
