The fastest path to a reliable match
A stamped, cast, or tagged part number is usually the strongest starting point. Photograph the entire component and each number before cleaning, because paint, rust, and wear can obscure identifying marks.
Model names alone are not always enough. Manufacturers may change a component within a production run, so the tractor serial number and the old part's physical details can be decisive.
- Part or casting number exactly as shown
- Machine make, model, and serial number
- Clear photos from multiple sides
- Mounting-hole spacing, shaft diameter, and connector style
- Any known superseded or alternate part number
What to include in your inquiry
Describe the failure and the assembly the part came from. A short explanation—such as no hydraulic pressure, damaged gear teeth, or a cracked housing—helps the parts team understand whether related pieces should be inspected too.
Frequently asked questions
Can a casting number identify the exact service part?
Sometimes, but not always. A casting number may identify the housing or casting rather than the complete serviced assembly, so model and serial information still matter.
What if the old part has no readable number?
Send the machine model and serial number, measurements, connection details, and several well-lit photos. Those facts provide the next-best basis for comparison.
