For Chinese 4-stroke CG 125cc/150cc motorcycle engines · OEM replacement

This is a replacement oil pump for Chinese 4-stroke CG 125cc/150cc motorcycle engines. The oil pump is the heart of the engine's lubrication system, responsible for delivering oil from the sump to all moving parts, ensuring proper lubrication of the crankshaft, connecting rods, pistons, valve train, and other critical components.

Manufactured with precision engineering, this oil pump ensures stable oil pressure and flow, effectively reducing engine wear and extending engine life. It is the ideal replacement when the original oil pump fails or wears out, causing low oil pressure issues.

The oil pump is the "heart" of the engine, responsible for delivering oil to all components requiring lubrication:

• Lubrication & Wear Reduction: Creates an oil film between moving parts, reducing metal-to-metal contact, friction, and wear.
• Cooling: Circulating oil carries away heat from internal engine components.
• Cleaning: Flushes away metal particles and carbon deposits from internal engine surfaces.
• Sealing: Forms an oil seal between piston rings and cylinder walls, improving compression.
• Rust Prevention: Protects metal surfaces from oxidation and corrosion.

Consequences of Oil Pump Failure: Low oil pressure leads to inadequate lubrication, causing abnormal noise, overheating, seized pistons, spun bearings, and potentially catastrophic engine failure. Regular inspection and timely replacement of a faulty oil pump is critical.

This oil pump primarily fits the following engines and vehicles:

• CG 125cc Engines (CG125, CB125, etc.)
• CG 150cc Engines (CG150, CB150, etc.)
• Chinese motorcycles using CG series engines
• Other vehicles using the same oil pump design

Common models include:

• CG125 / CG150 series motorcycles
• CB125 / CB150 series motorcycles
• Various Chinese CG engine models
• Some ATVs and trikes using CG engines

• Oil Pressure Light: Dashboard oil pressure warning light illuminates or flashes.
• Engine Noise: Unusual noises from valve train, crankshaft area, especially metallic knocking sounds.
• Overheating: Engine temperature runs abnormally high due to poor cooling.
• Low Oil Pressure: Pressure reading below specifications when tested with a gauge.
• No Oil Circulation: Lack of oil return or splash visible when opening the valve cover.

If you experience these symptoms, stop using the engine immediately, inspect the oil pump, and replace if necessary.

• OEM Specifications: Manufactured to CG engine original specifications for perfect fit.
• Precision Machining: Precision manufacturing ensures proper rotor clearances for stable oil pressure.
• Wear-Resistant Materials: Made from quality materials for long service life.
• Reliable Oil Supply: Ensures adequate oil delivery under all operating conditions.
• Direct Replacement: Perfect substitute for original damaged or worn oil pump.

🔧 Installation Tip

1. The oil pump is located inside the engine; replacement requires removing the engine side cover or oil pan.
2. Professional installation or significant engine repair experience is recommended.
3. Clean the mounting surface before installation to prevent debris from entering oil passages.
4. Pay attention to pump positioning and drive gear engagement during installation.
5. After installation, fill with proper amount of oil. Before starting, you may remove the spark plug and crank the engine to prime the oil pump.
6. After starting, check for normal oil pressure and inspect for any oil leaks.
