Confirm your engine match

Send a clear photograph of the complete engine plate, including the serial number, full model suffix and arrangement or build number where shown.
Include the machine model, serial number and use case, plus photographs of the current engine and its mounting, flywheel and driven-equipment connections.

Buyer guide

Use engine serial/arrangement and the host machine serial number when comparing a replacement.
