The 22U-01-21310 (22U0121310) part number Komatsu hydraulic pump and motor vibration damper is designed to dampen torsional vibrations in the power transmission line. Absorbing sudden load changes that heavy machinery is exposed to during operation, this component maintains the mechanical compatibility between the hydraulic pump and the engine flange.
Compatible Series and Models
The specified vibration damper is used in PC200-6, PC250-6, PC200-7, PC220-7, PC200-8, PC220-8, and PC270-8 excavator series groups. It is recommended to measure the tolerances of the existing flywheel and pump coupling housings before the replacement process.
Assembly and Inspection Stages
- Check for wear or clearance in the vanes and spring housings.
- Ensure that the spline gear structure is fully aligned with the shaft.
- Tighten the mounting bolts in a cross pattern according to the manufacturer's torque values.
