Komatsu PC290 Bucket Pins and Bushings

Wear at the bucket and H-link pivot points can create excessive clearance, side-to-side bucket movement, and linkage play. Replacing worn Komatsu PC290 pins and bushings helps restore proper fit at these heavily loaded pivot locations.

This kit provides a complete solution for customers looking for PC290 bucket pins, PC290 bucket bushings, PC290 bucket-link pins, PC290 H-link bushings, PC290 linkage pins and bushings, or a complete PC290 bucket pin kit.

Fits Komatsu PC290 Excavators

This Komatsu PC290 bucket link pin and bushing kit is designed for applicable PC290 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 PC290 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 PC290 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.
