KOMATSU 566-01-82190 Rubber
Product Overview
The KOMATSU 566-01-82190 Rubber is a Genuine Komatsu OEM rubber damper element (cushion) designed for use within the engine damper (flexible coupling) assembly. It functions as a torsional damping element that absorbs vibration and shock loads between the engine and drivetrain, helping to ensure smooth torque transmission while protecting driveline components from excessive stress. Parts catalogs identify this component as Rubber (also referred to as Cushion) within the engine damper assembly.
Manufactured to Komatsu’s OEM standards, the 566-01-82190 Rubber is engineered to withstand continuous cyclic loading, engine vibration, and heavy-duty mining and construction operating conditions. Designed as a direct OEM replacement, it restores the original damping characteristics and performance of the driveline coupling.

Application Information
The KOMATSU 566-01-82190 Rubber is installed within the engine damper assembly, where multiple rubber elements are positioned between the coupling bodies to absorb torsional vibration generated by the diesel engine. These rubber elements cushion shock loads, reduce drivetrain vibration, and protect shafts, bearings, transmissions, and related power train components from excessive stress.
The component is designed to withstand:
- Continuous torsional loading
- Engine vibration
- Heavy shock loads
- Repeated compression cycles
- Mining and quarry operating conditions
- Long-duty heavy-haul service
Routine inspection and replacement of worn damper rubber elements help maintain proper vibration damping and extend the service life of the complete driveline assembly.

Compatibility varies depending on the machine model, serial number, and damper configuration. Always verify compatibility using the machine’s Product Identification Number (PIN), Machine Serial Number, and existing part number before ordering.
Additional Compatibility Information
The 566-01-82190 Rubber is a configuration-specific driveline component. Before installation, verify:
- Machine model
- Machine Serial Number
- Product Identification Number (PIN)
- Engine damper configuration
- Existing rubber element part number
- Associated coupling, shaft, bearing, and seal components
The engine damper assembly typically uses four of these rubber elements. For balanced vibration damping and optimum performance, Komatsu service practice generally recommends inspecting or replacing the complete set during major driveline or damper service.
