Crankshaft Oil Seal for 2027 Yamaha 205SD 1800 - Replaces 6LE-81167-00-00

Crankshaft Oil Seal for 2027 Yamaha 205SD 1800, a direct replacement for OEM part number 6LE-81167-00-00.

Crankshaft oil seals seal the ends of the crankshaft where it exits the crankcase, keeping oil in and keeping water and air out. On two-stroke engines the crank seals also hold crankcase pressure, which is critical for correct fuel delivery and engine performance.

When You Need It

• Oil or fuel weeping around the end of the crankshaft
• Erratic idle or idle that hangs high (common sign of an air leak on two-strokes)
• Engine fails a leak-down or pressure test
• Any engine rebuild or crankshaft service

Fitting Tips

• Always fit new seals when the crankcase is split or the crank is removed
• Lightly lubricate the seal lip before installation and press in squarely
