Excellent Inexpensive Replacement Gear · For CG125, CG150, CG200 Engines · Drives Valve Timing System

This is the CG Crankshaft Timing Gear — an excellent inexpensive replacement for the original crankshaft timing gear. This component is a core part of the engine's valve timing system, responsible for transmitting power from the crankshaft to the timing chain or belt, driving the camshaft to control valve timing.

The crankshaft timing gear is mounted on the end of the crankshaft and meshes with the camshaft timing gear via a timing chain or belt. Precise timing gear engagement ensures accurate synchronization between the crankshaft and camshaft, which is essential for proper engine operation. Manufactured from high-quality steel with precision machining and heat treatment, this gear features accurate tooth profiles, high strength, and excellent wear resistance. This is the perfect replacement when the original crankshaft timing gear suffers from wear, broken teeth, or timing inaccuracy.

This crankshaft timing gear is compatible with the following engines and vehicles:

• Engine Types: CG125, CG150, CG200 4-stroke engines
• Vehicle Types: Honda CG series, Chinese-made CG series motorcycles, dirt bikes, street bikes
• Mounting Location: End of crankshaft, magneto side
• Applications: Engine overhaul, timing chain replacement, valve train repair, worn gear replacement

• High-Quality Alloy Steel: Made from high-strength alloy steel with heat treatment for excellent wear resistance and durability.
• Precision Tooth Machining: Gear teeth are precision-machined for accurate engagement with timing chains or belts and smooth operation.
• Clear Timing Marks: Features clear timing marks for easy alignment during installation to ensure accurate valve timing.
• OEM Specification Standards: Manufactured to CG series original specifications for perfect fitment.
• Excellent Value: High cost-performance ratio makes it an ideal choice for engine overhaul and valve train repair.
• Essential Overhaul Component: The crankshaft timing gear is a key component of the valve timing system — this product is critical for restoring engine performance.

🔧 Installation Guide

1. Ensure the engine is completely disassembled and the crankshaft is removed before starting.
2. Remove the old crankshaft timing gear, noting the keyway position and installation orientation.
3. Clean the crankshaft end and keyway, inspect the keyway for damage.
4. When installing the new timing gear, ensure keyway alignment and use a press tool to avoid impact damage.
5. When installing the timing chain or belt, ensure timing marks are aligned.
6. After installation, manually rotate the crankshaft several times to verify timing marks realign.
7. Reinstall the crankcase and other engine components, start the engine, and check for proper operation.
8. It is recommended to replace the timing chain and tensioner simultaneously for optimal valve train performance.

⚠️ Important Notice: This product is the CG Crankshaft Timing Gear, designed for CG125, CG150, and CG200 4-stroke engines.
Spec Confirmation: Before purchasing, verify that your original crankshaft timing gear specifications match this product to ensure compatibility.
Installation Caution: Crankshaft timing gear installation involves engine timing components. Align timing marks carefully during installation — failure to do so can cause valve-to-piston contact resulting in catastrophic engine damage. Professional installation is strongly recommended.
