Installation and Maintenance Recommendations
- Professional Installation: It is strongly recommended that the installation be carried out by a professional technician at a formal repair shop. During installation, it is essential to clean and inspect the flywheel surface and replace the crankshaft rear oil seal to prevent contamination of the new clutch with oil dirt.
- Proper Running-in: After the new clutch is installed, it needs to be run in gently for about 500 kilometers. Avoid sudden acceleration, heavy loads, and semi-linkage operations to ensure that the friction surfaces are fully engaged, perform at their best, and extend their lifespan.
- Regular Inspection: Regularly check for leaks in the clutch slave cylinder and master cylinder, and ensure that the free travel of the clutch pedal is within the standard range.

Frequently Asked Questions (FAQ)
Q1: Is this clutch kit suitable for my XX brand XX model truck?
A: The part number 3400700372 corresponds to a specific clutch specification. Although it is widely compatible with various heavy-duty truck models, the most accurate way is to provide your vehicle's VIN code (chassis number) or contact our customer service personnel, who will perform an accurate model matching query for you.
Q2: Does the kit include a release bearing and alignment tool?
A: Yes. Our 3400700372 is a complete kit that includes a clutch pressure plate, clutch friction plates, a release bearing, and a special alignment tool for centering during installation, providing you with a one-stop solution.
Q3: Does the new clutch need to be broken in? How should I do it?
A: It is very necessary! Proper break-in is crucial for the life of the clutch. It is recommended to avoid rapid acceleration, high-speed gear shifting, towing heavy loads, and prolonged semi-linkage (such as long periods of low-speed crawling) within the first 500 kilometers after installation. Maintain smooth driving to allow the friction plates and pressure plate to gradually achieve perfect fit.
Q4: My car's clutch feels heavy and difficult to press down; can replacing this kit improve it?
A: Clutch pedal heaviness is usually not directly related to the clutch kit itself; the problem may lie in the separation mechanism (such as the release fork, clutch slave/master cylinder) or the cable. Replacing the new clutch kit may slightly improve the situation, but it is recommended that you also check and lubricate the entire clutch operating mechanism to thoroughly solve the problem.
Q5: Do your products have a warranty?
A: Yes. We offer a limited warranty of 12 months or 100,000 kilometers on this clutch kit (whichever comes first). For specific terms, please refer to the warranty card attached with the product or consult our sales staff.
Q6: How can I tell if my clutch needs to be replaced?
A: Common signs include:
• Slipping: Engine speed increases but vehicle speed improves slowly, especially noticeable under heavy load or uphill conditions.
• Incomplete separation: Difficulty in shifting gears or a clunking sound from the transmission when pressing the clutch pedal.
• Vibration: Abnormal vibration occurs when starting the vehicle.
• Unusual feel of the pedal: Increased, heavier, or softer pedal travel.
• Unusual noise: Abnormal sounds when pressing or releasing the pedal.
If you encounter any of the above situations, please inspect them promptly.
