Komatsu Large Excavator Pins and Bushings
Komatsu Large Excavator Pins and Bushings is a supported WQC Parts hub because it already connects buyers to real product paths. Use this page to narrow from the broad Komatsu model or system into listed products, serial-aware collections, or specific component groups.
For the best result, start with the exact model and serial number, then choose the closest series, workgroup, product group, or part number shown below. Do not rely on description alone when a serial break, attachment arrangement, arm length, bucket linkage, or hydraulic configuration may change the correct part.

The product links below are intended for buyers who already know the part number or can confirm the application. If fitment is uncertain, contact WQC Parts before ordering.
Before Ordering: Confirm the Machine and Serial Range
Large Excavator Pins and Bushings parts can change by series, serial number break, regional arrangement, attachment package, and installed component group. Use this hub to narrow the path, but confirm the final part number against the machine serial number, parts book reference, or existing part stamping before ordering.
- Best information to provide: machine model, serial number, current part number, component location, and a photo if available.
- For pins, bushings, service kits, pumps, hydraulic parts, and engine components, similar descriptions may still represent different parts.
- When you are unsure, use the quote path instead of guessing from a broad description.

Komatsu large excavator pins and bushings are heavy-duty wear components used throughout boom pivots, arm joints, bucket linkages, and other high-load articulation points on production-class excavators. These machines operate under extreme digging forces and repetitive duty cycles in quarry, mining, demolition, and large-scale earthmoving applications.
Because larger excavators carry higher operating loads, pivot components must be manufactured to tight tolerances and heat-treated for long service life. Replacing worn pins and bushings helps restore proper joint fit, reduce looseness in linkage assemblies, and prevent accelerated wear in major structural components.
WQC Parts supplies replacement pins and bushings for Komatsu large excavators manufactured for reliable fitment and durability. Use this page to browse popular part numbers and then drill down by machine model and series as we expand serial-range breakdowns.
