⚙️ Product Features

Direct OEM Replacement: Perfectly matches CFMoto OEM part numbers 0180-041000 / CF188-041000, ensuring precise fitment.
High-Strength Alloy Steel: Forged from high-quality alloy steel with exceptional fatigue strength and wear resistance to withstand combustion pressures.
Precision Machining: Main journals and crankpins are precision-ground for high surface finish and tight tolerances, ensuring proper bearing fitment.
Dynamic Balancing: The crankshaft assembly undergoes precise dynamic balancing to minimize vibration at high speeds, extending engine life.
Integrated Gears: Timing gears and balance shaft gears are integrated, ensuring accurate valve timing and balance shaft drive.

✅ Importance of Crankshaft Replacement: The crankshaft is one of the most critical and highly stressed components in an engine. After prolonged high-load operation, the crankshaft may develop wear on main or connecting rod journals, fatigue cracks, or bending. These issues lead to engine knocking, increased vibration, low oil pressure, and in severe cases, crankshaft failure resulting in complete engine destruction. During an engine overhaul, if the crankshaft is found to be out of specification or damaged, it must be replaced promptly to ensure engine performance and reliability.

⚠️ Verify Before Ordering: Please ensure your vehicle model and engine type are listed in the fitment guide, and verify the crankshaft end gear specifications match your original part. Crankshaft replacement is a major engine overhaul procedure requiring specialized knowledge and tools. Installation must be performed by an experienced professional technician strictly following the service manual, with simultaneous replacement of bearings, seals, and related components.
