1043U (RD7941  Idle Gear)

Genuine Shimano Idle Gear (part #1043U) — this oscillation system gear transfers rotational power from the drive train to the worm shaft, producing the smooth back-and-forth spool travel that ensures even line lay. Worn teeth on the idle gear create clicking, grinding, or uneven line distribution that compromises casting distance and accuracy. Cross-references with Shimano part number RD7941. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
