It is designed for customers replacing worn Komatsu PC290 bucket pins, bucket bushings, bucket-link pins, H-link bushings, seals, shims, and grease fittings as part of a complete bucket-linkage repair.

Rather than sourcing each component separately, this kit provides the essential PC290 bucket-linkage wear parts together in one package.

Complete PC290 Bucket Pin & Bushing Kit

This Komatsu PC290 bucket pin and bushing kit includes:

• 2 bucket pins

• 2 bucket-link pins

• H-link bushings

The retaining hardware used to secure the pins from backing out may be reused if serviceable or sourced separately when replacement is required.

Komatsu PC290 Bucket Pins and Bushings

Wear at the bucket and bucket-link pivot points can create excessive movement between the bucket, arm, and H-link. As clearances increase, the bucket can develop side-to-side movement, looseness, and excessive linkage play.

Replacing worn PC290 bucket pins and bushings helps restore proper fit at these heavily loaded pivot points. This kit services the primary bucket and bucket-link locations rather than replacing only one pin or bushing.

European-Made Pins & Bushings for Komatsu Excavators

The pins and bushings used in this Komatsu PC290 bucket linkage kit are European-made and manufactured for demanding Komatsu excavator applications.

The pins are manufactured from 42CrMo4 alloy steel and induction hardened to achieve a surface hardness of 58–62 HRC to a depth of up to 5 mm. This combination provides a hardened wear surface while maintaining the strength required at heavily loaded Komatsu excavator bucket and linkage pivot points.

The bushings are precision ground on both the inside diameter and outside diameter to provide accurate fit between the pin, bushing, and machine bore.

These manufacturing specifications are designed for the repetitive loading, articulation, and wear conditions found in Komatsu PC290 bucket pins, H-link bushings, bucket-link pins, and excavator linkage components.

PC290 Pin & Bushing Specifications

• Pin material: 42CrMo4 alloy steel

• Heat treatment: Induction hardened

• Surface hardness: 58–62 HRC

• Hardening depth: Up to 5 mm

• Bushings: Precision ground on inside and outside diameters

• Manufacturing: European-made

• Application: Komatsu excavator bucket and linkage systems

Fits Komatsu PC290 Excavators

This Komatsu PC290 bucket link pin and bushing kit is designed for the PC290 machine family across applicable PC290 series and configurations.

Although Komatsu OEM pin and bushing part numbers may change between PC290 series, the applicable components cross-reference to the bucket-link kit configuration represented by this product.

This allows customers searching for PC290 bucket pins, PC290 bucket bushings, PC290 H-link bushings, or a complete Komatsu PC290 bucket pin kit to purchase a model-focused kit without needing a separate product for every dash series.

Rebuild the Complete PC290 Bucket Linkage

The Komatsu PC290 bucket linkage operates through several heavily loaded pivot points. As pins and bushings wear, increasing clearance can affect bucket movement and accelerate wear on adjoining linkage components.

Replacing only a bucket pin may not fully correct excessive linkage play if the mating bushings, H-link bushings, dust seals, or shims are also worn.

This Komatsu PC290 bucket pin and bushing kit is designed as a complete bucket-linkage wear package.

The included H-link bushings and dust seals help restore the linkage pivot while protecting the bushing surfaces from contamination. The supplied shims provide the spacing required during assembly, while new grease fittings allow the repaired pivot points to be properly lubricated after installation.
