Here's why:
* Briggs & Stratton makes many different 8 hp engines. Even within the "horizontal" category, there are variations in shaft size and other specifications depending on the intended application (lawnmower, generator, etc.).
* Shaft size is critical for proper coupling. You need the right size to fit your equipment's attachment or pulley.
To determine the shaft size:
1. Find the model number: It's typically located on a metal tag attached to the engine, often near the engine's valve cover.
2. Consult the Briggs & Stratton website: Go to their website (www.briggsandstratton.com) and use their online parts catalog to find your specific engine model.
3. Check the engine specifications: The parts catalog or manual will list the shaft size in inches or millimeters.
Alternatively, you can:
* Contact Briggs & Stratton customer service: They can assist you with finding the shaft size based on your engine's model number.
* Measure the shaft yourself: If you're comfortable with this, carefully measure the diameter of the shaft with a ruler or calipers.
Remember: Safety first! Before measuring or working on the engine, make sure it's disconnected from power and cooled down.
