10DYJ (RD20282 Idle Gear B Shaft)

Genuine Shimano Idle Gear B Shaft (part #10DYJ) — this shaft supports the B idle gear in the oscillation mechanism of Shimano spinning reels, enabling the spool to travel up and down evenly during line retrieval. A worn idle gear shaft leads to uneven line lay, spool wobble, or a grinding sensation during the crank. Cross-references with Shimano part number RD20282. OEM replacement ensures factory-spec tolerances and smooth oscillation performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano spinning reel parts.
