FINDING THE MODEL AND TYPE NUMBERS
Not sure what to look for? Here are some quick tips to get you started:
On the Engine:
- Model numbers are located on the physical engine and usually contain a combination of letters and numbers
- The numbering system is often segmented into 3 sections: [Model Number] - [Engine Type Number] - [Code Number]
- Your model number will be either 6, 7, 11 or 12 characters in length
On the Product:
- Model numbers are located in different areas on the product - sometimes on the frame, base, or elsewhere. Use our visual guides for reference
- The numbering system is often segmented into 2 sections: [Model Number] - [Revision Number]
- Your model number will be 6 characters in length + the revision number
