CUMMINS
3697975 torsional vibration damper is a professional engine vibration damping component customized for Foton commercial trucks with Cummins diesel engines. Installed on the engine crankshaft end, it targets and suppresses periodic torsional vibration generated by fuel combustion and piston reciprocating operation. This damper converts vibration energy into heat dissipation, stabilizes crankshaft rotation balance, and solves common problems such as engine jitter, abnormal resonance noise, accelerated crankshaft wear, belt jitter and loose accessories caused by fatigue and aging of old damping parts, maintaining stable power output for long-distance and full-load transport vehicles.
1. Efficient Torsional Vibration Suppression: Precision damping structure effectively offsets crankshaft torsion and resonance, eliminates engine idle jitter and running vibration, optimizes overall engine operating smoothness.
2. High Temperature & Fatigue Resistance: Adopts upgraded high-elastic damping medium and high-strength metal outer ring, stable performance under long-term high-temperature engine compartment environment, no damping attenuation or aging failure.
3. Reduce Overall Mechanical Wear: Greatly buffer instantaneous torque impact and vibration amplitude, reduce abrasion of crankshaft, bearings, pulleys and transmission accessories, effectively extend engine service life.
4. Noise Reduction & Stable Operation: Suppress high-frequency engine resonance and metal collision noise, improve vehicle driving comfort and avoid abnormal knocking faults during acceleration and deceleration.
5. Anti-Degradation & Long Service Life: Special anti-aging and oil-resistant treatment, resist erosion of engine oil, dust and high-temperature gas, avoid damping medium failure and structural cracking.
6. Precise Matching Dimension: Standard mounting hole position and overall specification, perfectly fit Cummins engine crankshaft assembly of Foton trucks, support plug-and-play installation without cutting or secondary adjustment.
7. Strict Factory Performance Testing: Finished products pass vibration fatigue test, high and low temperature cycle test and dynamic balance calibration, stable batch quality for fleet maintenance and bulk wholesale procurement.
