For CG125 · CG150 4-Stroke Engines · Standard Quality · Cost-Effective Replacement

This is the CG Counter Shaft Assembly (Transmission Countershaft), a high-quality, cost-effective replacement for the transmission system in CG125 and CG150 4-stroke engines. Specifically designed for CG series engines, this countershaft is suitable for motorcycles, ATVs, and various other vehicles, making it the ideal choice for transmission repairs or performance restoration.

The countershaft is a core component of the transmission, working together with the main shaft to transmit engine power to the drive wheel through gear engagement at different speeds. Manufactured from high-quality alloy steel with precision machining and heat treatment, this countershaft offers excellent strength, wear resistance, and fatigue resistance, ensuring smooth shifting and reliable operation.

This countershaft assembly fits vehicles equipped with CG125 and CG150 4-stroke engines, including but not limited to:

• High-Quality Alloy Steel: Manufactured from premium alloy steel for high strength and excellent toughness.
• Precision Machining: Shaft journals and gears precision-ground for accurate dimensions and smooth operation.
• Carburized & Hardened: Surface carburized and hardened for high hardness, excellent wear resistance, and superior fatigue strength.
• OEM Specification: Manufactured to exact CG series engine factory specifications for perfect replacement of worn original components.
• Standard Quality: Standard quality manufacturing offers a cost-effective alternative to original components.
• Restores Performance: Replacing worn countershaft eliminates shifting issues and noise, restoring proper transmission function.

🔧 Installation Guide

1. Remove the engine from the frame.
2. Split the engine crankcase to access the transmission assembly.
3. Remove the shift mechanism, shift forks, and gear sets.
4. Remove the old countershaft and inspect bearings and gears for wear.
5. Clean the transmission case and inspect bearing bores for wear.
6. Install the new countershaft along with the associated gears and bearings.
7. Check gear mesh clearance and verify proper shift mechanism operation.
8. Assemble the engine crankcase and tighten case bolts to specified torque.
9. Reinstall the engine, add fresh engine oil, and start the engine to test shifting function.
Important Note: Transmission disassembly and assembly involve precision components. Pay attention to gear orientation and clearance during installation. Professional installation is strongly recommended.

⚠️ Important Notice: This is the CG Counter Shaft Assembly, designed for CG125 and CG150 4-stroke engines.
Spec Confirmation: Before purchasing, verify your engine model and transmission speed count (4 or 5 speeds) to ensure compatibility.
Installation Note: Transmission disassembly and assembly involve critical engine components and require specialized tools and expertise. Professional installation is strongly recommended. Pay attention to gear orientation and clearance during installation.
Recommended Parts: When replacing the countershaft, it is recommended to inspect the main shaft, gears, bearings, and shift forks for wear, and replace them if necessary to ensure overall transmission performance. Product images are for reference only; actual product may vary.
