INDEPENDENT MODEL-CODE AND SOURCING REVIEW
Caterpillar references accepted for structured RFQ review.
Caterpillar references often mix part numbers, machine serial ranges and revision codes. The review separates the installed component from the machine identity before any replacement route is proposed.
PRODUCT COVERAGE
What can enter the review process
CATEGORY ROUTES
Review Caterpillar references by product category
Start from the product category that matches the installed component, then submit the complete model code.
IDENTIFICATION HIERARCHY
How a Caterpillar reference moves from a name to a decision
Brand recognition is only the first routing step. The review narrows the inquiry from manufacturer name to product family, series, complete code and finally the installed interfaces and duty.
- Brand and aliasesCaterpillar, CAT, Caterpillar Inc.
- Product familySeparate the reference into the relevant valve, pump, motor or service-part group.
- Complete identifierPreserve every suffix, revision, material number and option character visible on the nameplate or document.
- Installed evidenceCompare interfaces, operating conditions and application before any replacement statement is released.
SERIES DIRECTORY

FAILURE-MODE REVIEW
Why the series rows need different evidence
These checks explain the decision risk behind each published reference. They are review rules, not a claim that every listed configuration is available.
| Reference | Mismatch risk | Evidence needed for release |
|---|---|---|
| CAT Piston Pump | Rotation, control, shaft, flange or port differences can prevent installation or damage the system. | Code breakdown, displacement/control data and dimensional interface comparison. |
