Komatsu Parts

Premium aftermarket Komatsu parts for your next repair

WQC Parts supplies aftermarket Komatsu parts for equipment owners, contractors, repair shops and fleet maintenance teams looking for a dependable replacement source. Whether the requirement is one part or a complete repair list, our focus is the specific component your machine needs. Search by the original part number to buy listed Komatsu parts online, or send the reference and quantity for a quotation when the item is not available for direct purchase.

Choosing Komatsu spare parts involves more than comparing a description and a price. The offered part, application details, source and warranty all belong in the buying decision. A replacement that looks similar is not necessarily suitable for the same serial range or installed arrangement. We encourage buyers to confirm the part number and machine details before ordering so that purchasing starts with the actual repair requirement.

Quality you can evaluate before you buy

For customers seeking premium quality Komatsu replacement parts, useful detail matters more than a broad promise. Review the individual listing for the offered product and application information, and ask about any specification or included item that affects the repair. Where a product carries the WQ Certified mark, it has been selected under WQC Parts’ internal quality requirements. For selected pins and bushings, those requirements address sourcing, material suitability, machined dimensions, fit and wear-surface quality.

The WQ Certified quality standard explains that review in more detail. The mark applies to qualifying products and does not represent every item in the collection as certified. WQC Parts is an independent supplier; aftermarket Komatsu parts are replacement options and are not represented as parts manufactured by Komatsu.

Komatsu replacement parts backed by warranty protection

Eligible Komatsu replacement parts purchased from WQC Parts are backed by a warranty period equivalent to the applicable OEM warranty period, unless different terms are stated on the product page, quotation, invoice or sales documentation. Coverage applies to qualifying defects in materials or workmanship under normal use and proper installation.

Review the WQC Parts warranty policy for coverage, exclusions and claim requirements. Genuine OEM, surplus, used and specially sourced items may carry different terms. If warranty coverage is important to your repair decision, ask us to confirm the terms for the specific part before ordering.

Buy online or request a quote for the part you need

Known part numbers provide the most direct route to available Komatsu parts online. If you need to establish the reference first, use the illustrated Komatsu parts catalog for supported models and assemblies, or send the full model, serial details, component location and existing markings to our team. The catalog helps identify references; availability and the offered replacement are confirmed in the listing or quotation.

For parts that are not listed, request a parts quote with the part number and quantity whenever possible. Tell us if you require a genuine OEM item rather than an aftermarket replacement. WQC Parts can review genuine-part sourcing where available, and the quotation should make the product type and applicable terms clear.
