Komatsu PC400 / PC400LC Parts
Komatsu PC400 / PC400LC Parts is a model-family hub built to move buyers from the machine model into real shopping and fitment paths. Use this page when you know the Komatsu model family but still need to narrow by system, serial range, component group, or part number.
This page is not intended to trap customers in generic related-resource loops. The first path below is the listed product collection. The remaining paths are only included where the current hub data supports a useful next step.
If you do not see the exact item listed here, send us the Komatsu part number, machine model, serial number, or parts book reference and we will help confirm the correct WQC Parts option.

Common PC400 Repair Areas
- Pins and bushings: bucket, arm/stick, boom, bellcrank, bucket link, cylinder pivot, and linkage wear parts where serial-aware collection data exists.
- Service kits: hydraulic cylinder seal kits and related repair kits where direct product links are available.
- Hydraulic and pump parts: confirm by part number, installed arrangement, pump tag, or parts-book reference before ordering.
- Engine, filters, cooling, electrical, and undercarriage: use the broad system hubs or send the part number for confirmation when a model-specific page is not available.
Before Ordering: Confirm the Machine and Serial Range
Komatsu PC400 / PC400LC parts can change by series, serial number break, regional arrangement, attachment package, and installed component group. Use this hub to narrow the path, but confirm the final part number against the machine serial number, parts book reference, or existing part stamping before ordering.
- Best information to provide: machine model, serial number, current part number, component location, and a photo if available.
- For pins, bushings, service kits, pumps, hydraulic parts, and engine components, similar descriptions may still represent different parts.
- When you are unsure, use the quote path instead of guessing from a broad description.
