Komatsu PC300-7 Pins and Bushings

Komatsu PC300-7 Pins and Bushings is a model-level reference page built to help buyers and technicians navigate Komatsu aftermarket pins and bushings with stronger fitment context. At 19PARTS, Keep Ops Moving means organizing PC300-series wear hardware by machine family, work-equipment area, and diagram-backed callout logic instead of relying on broad, generic parts pages.

The source data behind this hub includes 169 distinct part numbers across 27 work-equipment images for serial coverage such as 50001-UP (ECOT3). The most useful sections for this machine family are Arm, Boom, Boom to Arm Linkage and Bucket Linkage, which is exactly where pin, bushing, seal, spacer, and retention-hardware verification tends to matter most.

What this PC300-7 hub is built to help you find

  • Model-specific entry points for PC300-7 arm, boom, linkage, and bucket-joint wear areas
  • Serial-range-aware navigation before ordering Komatsu replacement pins and bushings
  • Clearer separation between similar part numbers used in different pivot locations
  • Authority content that supports deeper image-level and product-level verification

How to verify the correct Komatsu PC300-7 pin or bushing

Start with the exact machine model and the work-equipment area you are repairing, then confirm the correct diagram image, callout number, and serial range. On Komatsu excavators, a pin or bushing that looks similar on paper can still change by arm setup, boom arrangement, linkage geometry, lubrication type, or serial break.
