This is the CG 5 Speed Shaft of Gear Change (Shift Shaft Assembly), a high-quality, cost-effective replacement for the transmission shift system in CG125 and CG150 4-stroke engines. Specifically designed for CG series engines, this shift shaft is suitable for motorcycles, ATVs, and various other vehicles, making it the ideal choice for transmission repairs or shift performance restoration.

The shift shaft (also known as gear change shaft or shift drum) is the core component of the transmission shifting mechanism. It controls the movement of shift forks through its guide grooves to engage different gears. This shift shaft features a 5-speed configuration, manufactured from high-quality alloy steel with precision machining and heat treatment, offering excellent wear resistance and reliability for smooth shifting and accurate positioning.

This 5-speed shift shaft fits vehicles equipped with CG125 and CG150 4-stroke engines, including but not limited to:

• 5-Speed Configuration: Designed for 5-speed transmissions, providing a wider gear ratio range for optimized power delivery.
• High-Quality Alloy Steel: Manufactured from premium alloy steel for high strength and excellent toughness.
• Precision Machining: Guide grooves precision-machined for accurate dimensions and precise shift travel.
• 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.

🔧 Installation Guide

1. Remove the engine from the frame.
2. Split the engine crankcase to access the transmission assembly.
3. Remove the shift pawl, detent mechanism, and shift forks.
4. Remove the old shift shaft and inspect guide groove wear.
5. Clean the transmission case and inspect shift forks and detent mechanism.
6. Install the new shift shaft, ensuring the guide grooves correctly engage the shift forks.
7. Install the detent mechanism and shift pawl, and check for smooth shifting action.
8. Verify accurate gear positioning and smooth shift fork movement through all gears.
9. Assemble the engine crankcase and tighten case bolts to specified torque.
10. 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 the correct alignment between the shift shaft and shift forks during installation. Professional installation is strongly recommended.

⚠️ Important Notice: This is the CG 5 Speed Shaft of Gear Change (Shift Shaft Assembly), designed for CG125 and CG150 4-stroke engines with 5-speed transmissions.
Spec Confirmation: Before purchasing, verify your engine model and transmission speed count (5 speeds) to ensure compatibility. 4-speed and 5-speed shift shafts are not interchangeable — verify your original transmission speed count carefully.
Installation Note: Transmission disassembly and assembly involve critical engine components and require specialized tools and expertise. Professional installation is strongly recommended. Pay attention to the correct alignment between the shift shaft and shift forks during installation.
Recommended Parts: When replacing the shift shaft, it is recommended to inspect the shift forks, detent mechanism, and shift pawl for wear, and replace them if necessary to ensure overall shift system performance. Product images are for reference only; actual product may vary.
