Komatsu PC300 Pins and Bushings

Komatsu PC300 Pins and Bushings is the master authority hub for the PC300 family on 19PARTS. This page is built to help customers research Komatsu aftermarket pins and bushings by model family, work-equipment area, and image-backed diagram logic instead of treating every PC300 machine as if it uses the same hardware.

Because Komatsu PC300 excavators span multiple series, configurations, and work-equipment packages, correct fitment depends on more than just a broad model name. Serial range, arm arrangement, boom setup, bucket linkage geometry, and diagram callouts all matter. That is why our PC300 structure is broken down into model-specific and section-specific hubs to help customers Keep Ops Moving with better verification before purchase.

  • Model-level Komatsu PC300 pins and bushings hubs
  • Arm, boom, boom-to-arm linkage, and bucket-linkage breakdowns where the source data supports them
