📦 Part Number: 0GRV-064010-5000
⚙️ Countershaft · Transmission Countershaft · OEM Spec
📍 Installation: Transmission · Shift system
✅ Single unit · Premium alloy steel · OEM specification · Fits multiple CFMoto ATV models
This is a CFMoto OEM-spec countershaft, part number 0GRV-064010-5000, sold as a single unit. The countershaft is a core transmission component, working with the input shaft to achieve gear changes and torque multiplication through different gear pair engagements, transferring power to the output shaft — a critical part determining vehicle speed and traction.
The countershaft is subjected to high torque and impact loads. Over time, it may suffer from spline wear, bearing journal wear, or deformation due to wear, fatigue, or poor lubrication — resulting in transmission noise, shifting difficulty, or power transmission failure. Replacing it promptly with an OEM-spec countershaft is essential to restore transmission performance and ensure driving safety.
✅ OEM Quality Assurance: Manufactured to CFMoto's original technical standards using premium alloy steel with precision machining and heat treatment. Spline accuracy and strength are identical to genuine parts, ensuring a perfect replacement and reliable transmission performance.
This countershaft (part number 0GRV-064010-5000, single unit) fits the following CFMoto ATV models:
- CF400ATR-7L · CForce C4 Touring T3b (2026)
- CF400ATR-7S · CForce C4 (2026)
- CF400AZ-17S · CForce C4 (2026)
- CF400AZ-7L · CForce C4 Touring (2027)

• Unusual noise (grinding or whining) from the transmission.
• Shifting difficulty or gear skipping.
• Jerky power delivery during acceleration.
• Metal particles found in the transmission oil.
• Inspection reveals spline wear, bearing journal wear, or shaft deformation.
If any of these signs appear, please inspect and replace the countershaft promptly.
1. Confirm the countershaft part number is 0GRV-064010-5000 and matches your vehicle.
2. Remove the transmission assembly and extract the old countershaft.
3. Note the positions and order of bearings, gears, and shims.
4. Clean the mounting area and inspect the bearings and housing condition.
5. Install the new countershaft, ensuring proper gear meshing.
6. Torque all related bolts to specification.
7. Reassemble the transmission and fill with appropriate transmission oil.
8. Test drive to confirm proper shifting and power transmission.
