    Large Aftermarket Komatsu Parts Selection For Current & Older Generation Equipment

    Komatsu has run through many dash generations on its core models, and each one changes something in the parts book. Our sourcing covers current dash numbers and machines up to 7 generations back, where dealer stocking has usually dropped off. We cross-reference older Komatsu OEM part numbers, superseded numbers, casting numbers, and component tags against available aftermarket parts. If an exact number is no longer readable, photos and dimensions are used to help narrow the replacement.

    We source aftermarket parts for current equipment and older PC, D, WA, GD, SK, and CK models. Our part selection covers undercarriage, final drives and swing components, hydraulics, engine and powertrain, cooling, electrical, operator station, and ground-engaging tools.

      How to Identify Komatsu Parts

      Komatsu machines use different parts within the same model family, so part identification should start with the most specific information available. The OEM part number is usually the fastest reference. Machine model (including dash- generation) and serial number help confirm serial breaks and production changes. Major assemblies may also have their own identification tags or numbers. When those markings are missing, providing clear photos and measurements will help narrow the search.

      Start With the OEM Number

      If the original Komatsu OEM part number is readable, use it as the first reference. EquipXR can check that number against available aftermarket replacements, cross-references, and superseded numbers.

      Confirm the Machine Model

      Provide the complete Komatsu model designation, including any suffixes shown on the machine. Providing the machine serial number helps confirm part fitment before a quote is finalized.

      Check the Serial Number

      Use the machine serial number when the application has a production break or multiple component arrangements. It is particularly useful when no reliable OEM number is available from the removed component.

      Check Component Identification

      Major components (engine models, hydraulic pump tags, transmissions, and axels) can have identification separate from the machine serial number. These references are useful when Komatsu installed more than one version in the same machine series.

      About Komatsu Equipment

      Komatsu has manufactured construction and mining equipment for more than a century. Komatsu Ltd. was established in 1921 in Komatsu, Ishikawa, Japan, and is the second largest construction equipment manufacturer in the world. North American operations run through Komatsu America Corp.

      The company is widely known for its excavators, dozers, wheel loaders, motor graders, haul trucks, and other heavy equipment used in construction, earthmoving, mining, infrastructure, and material-handling applications. With Komatsu machines operating across such a broad range of applications and with many older models remaining in service, replacement parts continue to be an important part of keeping this equipment productive.

      Komatsu logo

      EquipXR supplies aftermarket Komatsu parts for current and legacy machines, giving equipment owners and fleet managers additional options for maintaining, repairing, and rebuilding their equipment. We do not sell parts as Komatsu OEM products. Our parts coverage varies by model, serial range, and component, with options available for many current machines as well as older equipment that remains in daily service.

      Parts for Other Equipment Brands

      EquipXR also supplies aftermarket replacement parts for Caterpillar, John Deere, CASE, Bobcat, Liebherr, Dressta, Volvo, Hitachi, and other heavy equipment manufacturers. EquipXR helps mixed fleets source parts from several brands, rather than working with a separate supplier for each machine. Coverage varies by manufacturer, model, and part category. Send the OEM part numbers and machine information for each item, and we will check for available aftermarket replacements for the entire fleet request.

      Fast Parts Quotes

      Equipment downtime gets expensive quickly. Send the Komatsu part number and machine information you have, and EquipXR will check available aftermarket options and provide pricing with quick turnaround, so you can order the parts you need.

      Competitive Aftermarket Parts Pricing

      Our aftermarket replacement parts cost less than buying the equivalent repair part through an OEM dealer. We quote the available replacement based on the exact application, giving you another option when OEM pricing or lead time does not fit the repair.

      Support for Hard-to-Find Parts

      EquipXR can search aftermarket sources using the OEM number, machine information, component tag, photos, and other identifying details. Our parts team can work through dash-series changes, serial breaks, tags, and measurements to find the correct aftermarket replacement.

      Parts Staff Who Know Equipment

      EquipXR works with contractors, fleet managers, owner-operators, and service teams that already know the machines they maintain. Our parts staff focuses on fitment details, part-number matching, availability, pricing, and shipping information needed to move an order forward.

      Frequently Asked Questions

      Yes. EquipXR supplies aftermarket replacement parts for Komatsu dozers, excavators, loaders, graders, and other construction equipment. Available products range from individual repair components to complete assemblies. Parts are sourced for the specific machine and application rather than sold as OEM-branded Komatsu parts.

      EquipXR can source parts for many Komatsu dozers, excavators, mini-excavators, wheel loaders, motor graders, and other heavy equipment models. Coverage includes current and older model families. If your machine is not listed on this page, contact the parts team with the model and serial number to check availability.

      Yes. A Komatsu OEM part number is one of the best ways to identify an aftermarket replacement. EquipXR can use many original numbers to check cross-references, superseded numbers, and available replacement options. Machine model and serial number may also be needed when several component versions exist.

      It identifies the generation of that model. When providing your model number for ordering replacement parts, you should always include the dash number. A PC210LC-11 is the dash-11 version of the PC210LC and does not share every component with the dash-10. Undercarriage, hydraulics, and electrical parts will be the most likely parts to change between generations.

      EquipXR can supply track chains, track shoes, rollers, carrier rollers, idlers, sprockets, segments, track adjusters, recoil springs, pins, bushings, master links, and other Komatsu undercarriage components. Complete track groups may also be available for some machines.

      In three segments, written like 20Y-70-01240. The first segment ties the part to a machine group, which is why numbers rarely carry across model families. Komatsu also supersedes numbers over time, so an older reference from a parts book may cross forward to a current one.

      No. We only supply new aftermarket parts that meet or exceed OEM specifications and are covered by warranty. We do not offer used, rebuilt, or salvaged parts from other machines.

      Shipping time depends on current stock, warehouse location, part size, and destination. Many stocked aftermarket components can ship same day, after fitment is confirmed. If the machine is down or a part is needed for an emergency repair, include that in your quote request so EquipXR can check the fastest available inventory and shipping options.
