10G9R  (RD16271  Oscillating Gear)

Genuine Shimano Oscillating Gear (part #10G9R, RD16271) — the oscillating gear converts the rotary motion of the handle into the linear up-and-down movement of the spool, distributing line evenly for smooth, tangle-free casts. A worn or damaged oscillating gear causes uneven line lay, bunching, and reduced casting distance that gets progressively worse over time. Cross-references with Shimano part numbers 10G9R and RD16271. OEM replacement ensures perfect fit and factory performance.
