Komatsu PC380 Bucket Pins and Bushings

Fits Komatsu PC380 Excavators

This Komatsu PC380 bucket link pin and bushing kit is designed for applicable PC380 excavator series and configurations. Komatsu OEM part numbers may vary between series, but the applicable components cross-reference to the kit configuration represented by this product.

Complete PC380 Bucket Linkage Repair

Replacing only a worn bucket pin may not correct excessive linkage play when the mating bushings, H-link bushings, seals, or shims are also worn. This kit addresses the primary PC380 bucket and bucket-link wear points together.

The H-link bushings and dust seals help restore and protect the linkage pivots, the included shims provide proper assembly spacing, and new grease fittings allow the repaired pivot points to be properly lubricated after installation.
