Komatsu Pump Cross Reference Guide

Komatsu pump cross references can help connect alternate, analog, replacement, or related part numbers. This guide explains how cross-reference logic can help narrow down a pump search while still keeping the Komatsu parts book as the final authority for exact fitment.

Cross references are especially useful when a pump has been replaced before, when an older number appears in notes or on packaging, or when a customer is working from an alternate reference instead of the final Komatsu service part number.

What a Pump Cross Reference Can Tell You

A cross reference may help you:

  • Connect an alternate number to a known Komatsu pump part
  • Recognize equivalent or related pump references
  • Compare older numbers to newer listings
  • Move from an analog number toward the correct searchable part number

Cross references are useful research tools, but they are not a replacement for serial-number-based parts book verification.

When Cross References Are Most Useful

  • The original Komatsu number is missing or incomplete
  • You only have a supplier number, rebuilt-unit number, or alternate number
  • The pump has already been replaced once before
  • You are comparing replacement options across related listings
  • You are trying to connect a product number to a known machine application

Why Cross References Need Caution

Not every alternate number is a guaranteed one-to-one replacement. A cross reference may point to a related pump family, a previous service number, or a similar assembly that still needs to be confirmed by application.

That is why the Komatsu parts book for the exact machine serial number remains the final source of truth.

What to Compare When Reviewing Cross References

  • Komatsu part number
  • Machine model
  • Machine serial number
  • Pump type and system function
  • Any visible tag or casting numbers
  • Whether the pump is hydraulic, water, oil, fuel, injection, gear, pilot, or charge related

The more of those items you can match, the more reliable the cross-reference path becomes.

Use Cross References to Narrow the Search, Not End It

A strong cross-reference process helps you get closer faster. Once you find a likely Komatsu number, the best next step is usually to search that part number directly or verify it in the parts book.

If you already know the pump category, continue through the pump hub system below:

Examples of Pump Part Numbers in the Catalog

The examples below are real pump-related product pages represented in your catalog. They are included here as reference points for search and navigation.

If your exact part number is not shown, use the site search and compare the result against your machine serial number and parts book data.

Need Help Checking a Cross Reference?

If you have an alternate number, analog number, or uncertain pump reference, WQParts can help you review it. Share the machine model, serial number, and every visible number you have so the pump can be evaluated more accurately.

For final fitment confirmation, always verify against the Komatsu parts book for the exact machine serial number.
