The fastest way to order the correct Kawasaki FR, FS, or FX engine part is to begin with the engine identification—not only the mower’s model number. The engine model, specification, and original component number help separate parts that look similar but fit different configurations.
Engine Model Number
The model identifies the primary engine family and displacement configuration. Examples include FR651V, FR691V, FR730V, FS600V, FS651V, FS730V, FX691V, FX730V, and FX850V.
Do not reduce the model to only the horsepower rating. Multiple Kawasaki engines can have similar advertised power while using different filters, carburetors, starters, air-cleaner systems, and electrical components.
Specification Number
The specification number identifies a more specific engine configuration. It can affect components such as:
- Carburetor and fuel-shutoff solenoid
- Starter design
- Charging and ignition components
- Air-cleaner configuration
- Control linkage
- Exhaust or equipment-specific mounting
Serial Number
The serial number can help establish the production range and may be required when checking service information, recalls, or a mid-production component change.
Original Part Number
Whenever possible, compare the number printed, stamped, molded, or labeled on the original component. Clean the part carefully and inspect all sides. Numbers from the equipment manual, engine parts diagram, and component should be compared rather than relying on appearance alone.
Use an Illustrated Parts Diagram
Kawasaki provides an engine parts-lookup system with illustrated diagrams. Use the model and specification information to locate the correct diagram and confirm the reference number for the component.

Frequently Asked Questions
Is the mower model enough to find an engine part?
It may help, but the complete engine model and specification number provide a stronger basis because equipment models can use more than one engine configuration.
Can I order from a product photo alone?
No. Similar-looking components may have different dimensions, linkages, connectors, flow ratings, or internal calibration.
