Need help finding your Troy-Bilt model number?
Engine Manufacturers are required by law to identify their engines by model and specification ("spec") numbers, as well as serial number and sometimes type and code. The family number on your engine is not needed for parts lookup. The Model Tag for your Engine & Sub-Assembly will usually be found stamped or etched into a metal engine part in one of three places: above the muffler, above the spark plug, or between the overhead valve cover (OHV) and the air filter.
We strongly suggest taking pictures of your Model Tags or writing the information on your Parts Manual for reference with future repairs. As always, please feel free to call or email us if you need any help locating the Model Tags for your equipment or engine.
