10GMX  (RD5431  Drive Gear Bushing)

Genuine Shimano Drive Gear Bushing (part #10GMX) — this bushing supports the drive gear shaft, reducing friction and maintaining precise alignment between the drive gear and pinion gear. A worn drive gear bushing introduces play into the gear train, causing handle wobble, increased cranking effort, and accelerated gear tooth wear. Cross-references with Shimano part number RD5431. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
