Two engines that look identical can have different internal parts or fittings. The engine serial number is therefore one of the most reliable starting points for selecting the correct replacement part.
What does the serial number tell us?
Manufacturer catalogues use serial numbers to distinguish production configurations, certain revision levels and associated parts lists. Changes to the same engine model over time can affect part numbers.
What information should you provide with a parts request?
- Engine make
- Engine model
- Engine serial number
- Existing part number, if available
- A clear photograph of the part
- Information about the machine or equipment application
What happens if a part is mismatched?
An incompatible part may not fit, may affect engine performance or may delay the service. Verifying the engine configuration is particularly important for pistons, liners, bearings, gaskets and sensors.
Where is the serial number?
Its location depends on the engine make and family. It is usually on the engine identification label, a metal plate or a marked area of the block. If the label is illegible, the engine model and existing part details may offer another way to verify it.
