CF Moto Crankshaft Assy

Part Number: 0JYA-041000-20010 (Mark A) / 0JYA-041000-20020 (Mark B)

Product Type: Engine Core Component | Crankshaft Assembly

Total Length: 39 cm

Fitment: CFMoto 1000cc Series SSV (ZForce 950 / 1000 Series)

OEM-specification crankshaft assembly with a total length of 39cm. Designed for CFMoto 1000cc series SSV models, including ZForce 950 SPORT, ZForce 1000 Sport, and ZForce 1000 Crew, this is the core engine component that converts piston reciprocating motion into rotational motion to output power.

This product is a genuine CF Moto crankshaft assembly, available in two mark options: 0JYA-041000-20010 (Mark A) and 0JYA-041000-20020 (Mark B). The crankshaft is one of the most critical and highly stressed components in an engine, responsible for converting the reciprocating motion of the pistons into rotational motion and delivering power through the flywheel to the drivetrain. This crankshaft assembly is forged or cast from high-strength alloy steel, featuring precision machining, heat treatment, and dynamic balancing for exceptional strength, rigidity, and wear resistance. The total length is 39cm. Suitable for CFMoto 1000cc SSV engine overhauls or replacement, specifically for models built on the 2V91Y-D platform.

• OEM Match: Part numbers 0JYA-041000-20010 / 20020 correspond exactly with the CFMoto official parts system, ensuring direct replacement.
• High-Strength Material: Made from high-quality forged/cast alloy steel, offering exceptional fatigue and torsional strength.
• Precision Machining: Main journals and crankpins are precision-ground for high dimensional accuracy and surface finish, ensuring optimal bearing fit.
• Dynamic Balanced: Each crankshaft undergoes rigorous dynamic balancing to ensure smooth engine operation and minimize vibration.
• Surface Treatment: Journal surfaces feature special treatments (e.g., induction hardening or nitriding) for excellent wear resistance, extending engine life.
• Essential for Rebuilds: Must be replaced during major engine overhauls if the crankshaft is worn, scored, or cracked.

✅ Fault Indications: Common signs of a worn or damaged crankshaft include:
• Heavy knocking noises from the bottom of the engine (main or rod bearing noise);
• Low oil pressure;
• Abnormally high engine vibration;
• Engine fails to start or severe power loss.
If these symptoms occur, stop using the vehicle immediately and inspect the engine internally.

✅ Installation Tip: Crankshaft installation is one of the most critical steps in an engine overhaul. Always use new main and rod bearings, and tighten bearing cap bolts to the specified torque and sequence in the service manual. After installation, check that the crankshaft rotates freely. Professional installation by an experienced technician is mandatory.
