Caterpillar 225 Excavator - Parts & Specifications

Serial Number Location

To determine your Cat 225’s configuration and ensure accurate parts selection:

• Look for the serial number stamped on the main frame behind the cab or on the side of the undercarriage near the hydraulic tank

• A metal ID plate is also typically found inside the operator’s cab near the console or firewall

Use this to identify model year, hydraulic circuit type, and attachment compatibility.
