106RH  (RD15882  Idle Gear B (Small)

Genuine Shimano Idle Gear B Small (part #106RH, RD15882) — this smaller idle gear works within the reel's gear train to transfer rotational power between the main gear and pinion assembly, maintaining smooth and efficient retrieve performance. A worn or chipped small idle gear introduces play and backlash in the drive system, resulting in a sloppy retrieve feel and reduced cranking efficiency. Cross-references with Shimano part numbers 106RH and RD15882. OEM replacement ensures perfect fit and factory performance.
