104KM  (RD8766  Oil Cap)

Genuine Shimano Oil Cap (part #104KM) — this small cap seals the oil port on your reel body, keeping lubricant inside where it belongs and preventing dirt, water, and salt from entering the reel's internal mechanisms. A missing oil cap allows contaminants to infiltrate the gear train, leading to corrosion, rough operation, and premature component failure. Cross-references with Shimano part number RD8766. OEM replacement ensures perfect fit and factory performance. Available from Offshore Tackle & Repair in Stuart, FL — your trusted source for genuine Shimano reel parts.
