Komatsu Parts
WQC Parts organizes aftermarket Komatsu parts around how equipment owners, repair shops, dealers, and exporters actually search: by machine family, model, system, serial range, and exact part number. Use this page as the main gateway for Komatsu replacement parts, including pins and bushings, seals, filters, pumps, motors, electrical parts, service kits, and other machine repair categories.
Start With the Machine Family

Komatsu Wheel Loader Parts
Find WA-series loader parts paths, including pins, bushings, linkage parts, hydraulic components, and service items.
Komatsu Pins & Bushings
Move directly into pivot parts for booms, arms, bucket linkage, loader linkage, and cylinder mounts.
Search by System or Repair Area
Hydraulic Parts
Use hydraulic paths for pumps, motors, cylinders, seal kits, hoses, fittings, and related repair components.
Engine Parts
Research aftermarket Komatsu engine-related parts by model, serial range, part number, and application.
Service Kits
Use service kit pages when the repair is based on maintenance, filter, seal, gasket, or rebuild-kit needs.
How to Confirm Komatsu Replacement Parts
The strongest way to identify a Komatsu replacement part is to combine the part number with the machine model and serial number. Descriptions alone are not enough because similar Komatsu machines can have different arrangements, regional specifications, and serial-number breaks.
- Use the exact Komatsu part number when available.
- Include the machine model and serial number with every quote request.
- Check whether the part belongs to a system, component group, or installed arrangement.
- For pins and bushings, confirm the pivot location and inspect the bore before ordering.
