The truck accessories included in the truck clutch kit:
The clutch kit is a complete set of accessories designed to repair faults in the heavy truck clutch system. Clutch kit mainly addresses common issues such as worn clutch plates, damaged pressure plates, and abnormal noises from the release bearing. It typically includes the core components required for clutch system maintenance, helping users quickly replace damaged parts and restore the normal function of the clutch. The clutch system is a key component for power transmission, and its performance directly affects the overall operational efficiency of the vehicle. Now, we will provide a detailed introduction from aspects such as the composition and functions of the repair kit, applicable scenarios, selection tips, brands and prices:
The core components of the clutch kit:
The clutch kit for different heavy truck models (such as tractor trucks, cargo trucks, and dump trucks) and different brands, but mainly consist of the following components:
1. Clutch plates (friction plates)
- Function: Transfer engine power to the gearbox through friction, and are the core wear-prone parts of the clutch.
- Material: Common materials include asbestos-based, metal-based, or ceramic-based. Heavy trucks mostly use metal-based or ceramic-based (high temperature resistance, wear resistance, suitable for heavy load requirements).
- Specifications: Diameter is usually 380mm – 430mm (such as Shaanxi Auto DELONG X3000 uses 430mm clutch plates), which needs to match the engine torque.
2. Clutch pressure plate assembly
- Function: Use spring pressure to press the clutch plates onto the flywheel to achieve power connection and disconnection.
- Structure: Includes pressure plate body, compression spring, release lever (or diaphragm spring), etc.
- Type: Diaphragm spring type (still applicable to most current vehicle types, with simple structure and easy operation, such as FOTON AUMAN EST model) and spiral spring type (suitable for large torque models, such as China Heavy Industry SITRAK C7H series)
3. Release bearing:
- Function: Push the release lever of the pressure plate to achieve clutch disconnection, reducing wear.
- Type: Dry release bearing (requires regular lubrication, low cost) and self-lubricating release bearing (no maintenance, longer lifespan)
4. Other clutch accessories
- Guidance bearing: Installed at the rear end of the crankshaft, supporting the input shaft of the gearbox to prevent shaking.
- Clutch cover bolts: Used to fix the pressure plate assembly, requiring high-strength bolts (such as 10.9 grade bolts).
- Adjustment pads / seals: Used for adjusting clutch clearance or sealing to prevent leakage.
Taking SHACMAN X5000 as an example, its clutch kit is specifically designed for the special pull-type clutch system of this model. It includes high-temperature resistant or ceramic material clutch plates, high-strength pressure plates, and one-time lubricated release bearings.
When is a clutch kit used?
In the maintenance field of commercial vehicles, cost control is a key concern for formal vehicle owners and fleet managers, but driver safety is of paramount importance. Therefore, regular inspection and maintenance are the most important guarantees for protecting safety. Clutch system wear is usually uneven, and replacing a single component alone can lead to poor coordination between new and old parts, even accelerating the overall system wear. The complete set of components provided by the repair kit ensure synchronous wear of each component, prolonging the overall lifespan. At the same time, it saves a significant amount of maintenance time costs.
Let’s analyze two failure cases of SINOTRUK HOWO T7H and FAW J6P:
A: The HOWO T7H heavy truck equipped with the Weichai WP10 engine experienced clutch slipping during operation. After replacing the clutch plates and pressure plates in the repair kit, the fault was easily resolved.
B: The separation bearing of the FAW J6P heavy truck made abnormal sounds. After disassembly, it was found that the rollers of the bearing were severely worn. After replacing the separation bearing and guidance bearing in the repair kit, the vehicle ran smoothly.
When replacing the clutch kit ?
- 1. Professional operation: The installation accuracy of the clutch system is high (such as the center positioning of the clutch plates), and it needs to be operated by a certified technician to avoid clutch shaking due to improper installation.
- 2. Clearance adjustment: After replacement, the free travel of the clutch pedal (usually 30-40mm) needs to be adjusted to ensure complete disconnection and smooth engagement.
- 3. Running-in requirements: New clutch plates need to be lightly loaded for 500-1000 kilometers of running-in to avoid sudden acceleration or heavy load impact.
- 4. Regular inspection: Check the thickness of the clutch plates every 50,000 kilometers (standard thickness is approximately 3-4mm, and when worn down to 1.5mm, replacement is required). 5. Lubrication Maintenance: Dry separation bearings require lubricating grease to be added every 20,000 kilometers. Maintenance-free bearings do not require maintenance but need regular listening for abnormal sounds.
Finally, the clutch repair kit, as an economical and efficient maintenance solution, is very popular among drivers. This maintenance tool not only reduces the overall operating costs but also significantly shortens the repair cycle and extends the service life of the clutch system.
