Standard 30H Hydraulic Pump Drive Rubber Coupling Assembly for Kobelco SK60-2, SK60-5

   Thank you for choosing SPARKLING MACHINERY. 
   The 30H rubber coupling assembly is manufactured using oil-resistant natural and synthetic elastomer blends integrated with heavy-duty steel bolt bushings and hub sleeves. Engineered to operate under continuous high-torque cycles and engine bay heat, it acts as a mechanical shock absorber between the flywheel and hydraulic pump. Replacing a hardened, sheared, or cracked coupling eliminates flywheel-to-pump vibration, prevents splined shaft wear, and restores smooth hydraulic power output.
