Warranty
WQC Parts is the public brand for WQ Certified Parts. This page supports customers buying aftermarket Komatsu parts, Komatsu replacement parts, and heavy equipment parts from WQCParts.com.
Warranty is part of the WQC Parts heavy equipment parts library, built to help buyers research replacement parts, wear components, service items, hardware, assemblies, and related machine components by part number, machine family, system, and application.
This page supports part-number and application lookup by model, system, and product family. It is written to guide buyers from a broad search into the correct product group, while avoiding the common mistake of assuming that similar descriptions always mean the same part.
What This Page Covers
Use this page when researching replacement parts for Komatsu or related heavy equipment applications. Depending on the machine and part family, fitment may depend on serial range, arrangement, component group, mounting location, pressure rating, dimensions, or parts-book diagram position.
- Machine-family navigation.
- Part-number verification.
- System-level product research.
- Fitment and serial-range checks.
How to Confirm the Correct Part
- Start with the original part number whenever it is available.
- Verify the machine model, serial number, and installed arrangement.
- Check the component group and diagram location when parts-book data is available.
- Compare dashed and non-dashed part-number formats when searching.
- Confirm quantity and notes before ordering pins, bushings, seals, hydraulic parts, and engine components.

Why This Matters
Heavy equipment parts often look interchangeable when described only by a short title. A bushing, pin, seal kit, valve, filter, pump, sensor, or gasket may change across serial breaks or component arrangements. Correct identification helps prevent downtime, avoid repeat repairs, and protect surrounding components.
