SANY Excavator Crane Clutch Driven Disc 60013906

The clutch driven disc in an excavator crane is a critical component that facilitates the engagement and disengagement of the clutch system. Here’s an overview of its function, importance, common issues, maintenance tips, and considerations for replacement:

Function and Importance

1. Clutch Engagement: The driven disc is part of the clutch assembly that connects the engine to the transmission. It allows for smooth engagement of the clutch when transitioning between gears or when starting and stopping the excavator crane.

2. Power Transmission: When the clutch is engaged, the driven disc transfers engine power to the transmission and subsequently to the wheels or tracks, enabling movement of the excavator crane.

Common Issues with Driven Discs

1. Wear and Tear: Continuous use and friction can cause the driven disc to wear out over time, especially if the clutch is engaged frequently or under heavy loads.

2. Slipping: A worn driven disc may lead to clutch slipping, where the engine revs but does not effectively transfer power to the transmission, affecting vehicle movement and efficiency.

3. Heat Damage: Excessive heat generated during operation can damage the driven disc, leading to warping or reduced friction material, further affecting clutch performance.

Maintenance and Troubleshooting Tips

1. Regular Inspection: Periodically inspect the driven disc for signs of wear, such as thinning of friction material or grooves on the surface.

2. Fluid Checks: Ensure proper lubrication and hydraulic fluid levels to prevent overheating of the clutch assembly, which can contribute to driven disc damage.

3. Operational Practices: Train operators to avoid excessive clutch use or abrupt shifts, which can accelerate wear on the driven disc and other clutch components.

Replacement and Installation

1. Diagnosis: If you notice symptoms such as clutch slipping, difficulty shifting gears, or unusual noises during clutch engagement, it may indicate issues with the driven disc.

2. Parts Sourcing: Purchase a genuine replacement driven disc or compatible part from authorized dealers or reputable suppliers, ensuring it matches the specifications of the excavator crane model.

3. Installation: Follow the manufacturer’s service manual instructions for removing the old driven disc and installing the new one. Proper alignment, torque specifications, and lubrication are crucial during installation to ensure optimal performance.

4. Testing: After installation, conduct operational tests to verify that the clutch engages smoothly and there are no issues with power transmission or clutch slipping.
