How to Find the Correct Komatsu Replacement Part

The most reliable way to identify a Komatsu replacement part is to combine the exact part number with the machine model and serial number. A description or machine model alone may not be enough because parts can change by serial break, installed arrangement, regional specification, engine configuration, or production revision.

  1. Locate the Komatsu part number. Check the existing part, parts book, service records, invoice, or previous repair documentation.
  2. Confirm the full machine model. Include series designations such as PC200LC, WA470, D65, or GD655 when applicable.
  3. Provide the machine serial number. Serial numbers help identify production changes and the correct installed arrangement.
  4. Identify the system or component group. Examples include boom, arm, bucket linkage, hydraulic pump, engine, transmission, final drive, or electrical system.
  5. Confirm the installation location. This is especially important for pins, bushings, seals, hoses, sensors, and similar-looking components.

For pins and bushings, inspect the pivot location and bore condition before ordering. Excessive bore wear, misalignment, damaged retainers, or worn seals may require additional repair beyond replacing the pin and bushing.

Aftermarket Komatsu Parts From WQC Parts

WQC Parts supplies aftermarket replacement parts for Komatsu construction and mining equipment. We work with equipment owners, contractors, repair shops, dealers, fleet operators, and exporters who need a practical alternative to purchasing through an OEM channel.

Our goal is not simply to list large numbers of part numbers. We organize the catalog around the ways buyers actually identify and purchase parts: machine type, model, serial range, system, component, pivot location, and exact part number. When the online catalog is not enough, our team can help narrow the search using the information available from the machine and the existing part.

WQC Parts is an independent aftermarket parts supplier and is not an authorized Komatsu dealer. Komatsu names, equipment models, and part numbers are used for identification, compatibility research, and fitment reference.

Frequently Asked Questions

Does WQC Parts sell OEM Komatsu parts?

WQC Parts focuses on aftermarket Komatsu replacement parts. We are an independent supplier and are not an authorized Komatsu dealer.

Can I order a Komatsu part using only the machine model?

Sometimes, but the machine model alone may not identify the correct part. Many components vary by serial range, engine arrangement, regional configuration, or installed option. A part number and machine serial number provide a safer basis for identification.

Why is the Komatsu serial number important?

Komatsu may change components during a model’s production run. The serial number helps identify the correct production range and can prevent ordering a part intended for a different arrangement.

How can I find my Komatsu part number?

Check the existing component for a stamped, cast, printed, or labeled number. You may also find the number in a Komatsu parts book, previous invoice, service record, maintenance document, or repair estimate.

Can WQC Parts help identify a Komatsu part?

Yes. Send us the part number when available, the complete machine model, machine serial number, component or system, installation location, and clear photographs. For pins and bushings, include the pivot location and available dimensions.

What types of Komatsu equipment do you support?

Our catalog includes aftermarket parts pathways for Komatsu excavators, wheel loaders, bulldozers, motor graders, dump trucks, log loaders, backhoe loaders, and compact equipment. Availability varies by model and part number.

Are all Komatsu parts shown in the online catalog?

No. The online catalog represents listed inventory and available product records, but additional parts may be available through our supplier network. Contact us when the part number you need is not shown.
