Installation Location and Function
1. Installed at the crankshaft output end, one side is connected to the crankshaft flange, and the other side is connected to the silicone oil torsional vibration damper (3628652). It serves as a transition adapter plate between the crankshaft and the damper;
2.Accurately transmits crankshaft torque, evenly distributes forces, and buffers alternating torsional impacts;
3. Aligns the damper coaxially to prevent eccentric rotation that could cause vibration, abnormal belt wear, or crankshaft fatigue fracture;
4. Featuring an eight-hole standard mounting position, it is compatible with the original K38/K50 silicone oil damper assembly.
Failure Replacement Scenarios
Flange surface dents, deformations, stripped bolt holes, misalignment;
Long-term heavy load resonance causing flange cracks and imbalance;
Synchronized replacement during major engine overhaul or when replacing the crankshaft damper (3628652);
Severe engine shaking, slipping of the damper outer ring, frequent oil leaks from the front of the crankshaft.
