Komatsu PC228 Bucket Link Pin & Bushing Kit

Komatsu PC228 Bucket Link Pin & Bushing Kit

Restore tight, dependable bucket linkage with a complete Komatsu PC228 bucket link pin and bushing kit designed for PC228 excavators across multiple series.

This complete PC228 pins and bushings kit includes the major wear components required to rebuild the bucket and H-link pivot points. It is designed for customers replacing worn Komatsu PC228 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 individually, this kit provides the essential PC228 bucket-linkage wear parts together in one package.

Complete PC228 Bucket Pin & Bushing Kit

This Komatsu PC228 bucket pin and bushing kit includes:

• 2 bucket pins
• 2 bucket-link pins
• H-link bushings
• H-link dust seals
• All required shims

Pin-retaining bolts and nuts are not included.

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

Komatsu PC228 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 PC228 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.

This kit covers components commonly searched for as:

European-Made Pins & Bushings for Komatsu Excavators

The pins and bushings used in this Komatsu PC228 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 PC228 bucket pins, H-link bushings, bucket-link pins, and excavator linkage components.

Fits Komatsu PC228 Excavators

This Komatsu PC228 bucket link pin and bushing kit is designed for the PC228 machine family across multiple PC228 series and configurations.

It is suitable for applicable PC228, PC228US, and PC228UU excavators using this common bucket-linkage configuration.

Although Komatsu OEM pin and bushing part numbers may change between PC228 series, those applications cross-reference back to the same bucket-link kit configuration represented by this product.

This allows customers searching for PC228 bucket pins, PC228US pins and bushings, PC228UU pins and bushings, PC228 bucket bushings, PC228 H-link bushings, or a complete Komatsu PC228 bucket pin kit to purchase the correct model-focused kit without requiring a separate product for every dash series.

Rebuild the Complete PC228 Bucket Linkage

The Komatsu PC228 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 when the mating bushings, H-link bushings, dust seals, or shims are also worn.

This Komatsu PC228 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.
