description

This 434-6573 is viscous torsional damper with laser welded sealed shell. The internal inertia ring works in silicone fluid. Relative motion between shell and inertia ring shears silicone to dissipate torsional vibration energy. Each damper passes air tightness test, dynamic balance and silicone durability test. Viscous damper maintains stable damping at high temperature, suitable for long full-load operation of C27 and C32 engine. It is critical protection part for heavy power units.

Part No.：434-6573
Name：CAT Viscous Torsional Damper
Type：Silicone viscous torsional damper
Fit engine：C27, C32
Process：Brand new OEM, laser weld sealing, air leak test, dynamic balance, silicone durability test

Advantages

1. Viscous silicone design, no rubber aging, stable damping under high temperature
2. Fully sealed laser welded housing, dust and oil resistant for mining environment
3. Precision balanced, suppress low frequency resonance and reduce persistent shake
4. Tuned for C27/C32 crankshaft natural frequency to prevent crankshaft fracture

FAQ 

Q1：Can 434-6573 interchange with 382-8019 rubber damper?
A：No. Damping principle, resonant frequency and flange dimension are different.
Q2：Is this a Reman part?
A：No. It is brand new sealed viscous damper assembly.
Q3：What symptoms will appear when this viscous damper fails?
A：Engine low-frequency resonance, crank crack, accelerated timing gear and bearing wear.
Q4：Should I replace it if housing looks intact with no leakage?
A：Replace by service interval. Silicone viscosity degrades over time and cannot be checked visually.
