Komatsu Hydraulic Motors & Swivels
Komatsu Hydraulic Motors & Swivels is a supported WQC Parts hub because it already connects buyers to real collection 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.
Before Ordering: Confirm the Machine and Serial Range
Hydraulic Motors & Swivels 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.
Need help confirming a Komatsu part? Contact WQC Parts
Komatsu hydraulic motors and swivels transfer hydraulic power to travel, swing, fan, and rotary circuits while allowing movement where needed.
This hub is designed for system-level searches where a buyer may know the repair area but still needs to identify the correct Komatsu part number, component group, or machine-family application. Use this page to move from a broad system search into the matching parent hub, product collection, and related machine-family pages.

How This Hub Should Be Used
Start with the machine model and serial range, then confirm the component group. For assemblies, verify whether you need a complete assembly, repair kit, seal kit, internal component, mounting part, or related hardware. Do not rely on a short product description alone when the part has multiple possible positions or applications.
Fitment Checks Before Ordering
Komatsu parts should be verified with more than a description. The safest match comes from the original part number, machine model, serial range, installed arrangement, and component location. The same description can appear in several parts-book groups with different dimensions, quantities, or notes.
- Confirm the machine model and serial number before ordering.
- Match the old part number when it is visible or available.
- Review diagram position, quantity, component group, and notes when parts-book information is available.
- For hydraulic, engine, seal, linkage, and undercarriage parts, verify the exact system and installed arrangement.
Why WQC Parts
WQC Parts organizes Komatsu replacement parts around how mechanics, fleet managers, parts buyers, and equipment owners actually search: by part number, machine family, repair system, model group, and component location. This structure helps reduce wrong-part orders and gives each collection a clear purpose inside the larger Komatsu parts catalog.
- Aftermarket Komatsu parts organized by machine family, system, and part number.
- Support for dashed and non-dashed part number searches where data is available.
- Internal linking between broad hubs, system hubs, model hubs, and product collections.
- Fitment-focused content designed to guide buyers toward the correct replacement part.
Frequently Asked Questions
Why create a separate hub for this category?
Focused hubs help buyers who search by component type and help Google understand the relationship between system-level parts, machine families, and product collections.
Can these parts overlap multiple Komatsu systems?
Yes. A pump, valve, seal, filter, or sensor may relate to more than one system. The final part number and parts-book location should decide fitment.
Should I order by title or part number?
Use the part number whenever possible. Titles help narrow the search, but serial range and component location are the final fitment checks.
