Oil Pump Shaft

CFMoto Oil Pump Shaft

Part Number: 0800-070004

Product Type: Engine Lubrication System | Oil Pump Drive Component

OEM oil pump shaft, the core drive component of the oil pump assembly. It is responsible for transmitting power from the crankshaft or balance shaft to the oil pump rotors, driving the oil pump to provide continuous and stable lubrication pressure for the engine.

This product is a genuine CFMoto oil pump shaft, part number 0800-070004. This shaft is a critical drive component for the oil pump in the engine's lubrication system. One end connects to the drive gear (typically driven by the crankshaft or balance shaft), and the other end drives the inner rotor of the oil pump. By transmitting rotational power to the pump core, the oil pump generates suction and pressurizes oil to distribute it to all engine friction surfaces. Manufactured from high-quality alloy steel with precision machining and heat treatment, this shaft offers high strength and excellent wear resistance, ensuring stable and reliable oil pump operation, which is crucial for extending engine life.

Product Features:

• OEM Part Number: 0800-070004
• Product Name: Oil Pump Shaft
• Material: High-Quality Alloy Steel
• Fitment: Compatible with various CFMoto 800cc models

• OEM Match: Part number 0800-070004 corresponds exactly with the CFMoto official parts system, ensuring direct replacement without any modifications.
• High-Strength Material: Made from high-quality alloy steel, offering excellent torsional strength and rigidity to withstand the torque required to drive the oil pump.
• Precision Machining: Critical areas such as journals and keyways are precision-machined to ensure accurate fit with bearings, oil seals, and rotors, reducing friction and wear.
• Heat-Treated Reinforcement: Undergoes special heat treatment for high surface hardness and excellent wear resistance, capable of withstanding prolonged high-speed rotation.
• Stable Lubrication: Ensures smooth power transmission, driving the oil pump to generate stable oil pressure and provide reliable lubrication protection for the engine.

✅ Fault Indications: If the oil pump shaft is worn or damaged, you may experience symptoms such as decreased oil pressure, poor engine lubrication, and increased noise from the oil pump (possibly abnormal sounds). In severe cases, it may cause the oil pump to seize or fail, leading to major engine failure such as cylinder scoring or bearing seizure. If these occur, inspect the oil pump assembly and related components promptly.

✅ Installation Tip: Before installation, clean the oil pump housing, bearing bore, and shaft journals. Check the keyway of the new shaft for proper fit with the drive gear. Ensure the shaft inserts smoothly into the bearings and rotor and rotates freely without binding. Check oil pressure after installation to ensure it returns to normal. Professional installation by an experienced technician is recommended.
