One New Aftermarket Replacement Flywheel Key Fits Briggs and Stratton (B&S) Small Engines
This flywheel key installs between the crankshaft and flywheel to maintain precise alignment and ensure accurate ignition timing in Fits Briggs and Stratton small engines. The key is designed to seat securely in the crankshaft keyway and eliminate play between the flywheel and crankshaft. It also serves as a sacrificial component -- if the mower blade strikes a hard object, the soft metal key can shear to absorb the impact and protect the crankshaft and flywheel from more costly damage. Replace this part any time shearing or deformation is found during inspection.
Compatible With
Fits Briggs and Stratton (B&S): A wide range of Fits Briggs and Stratton small engines used in lawn mowers, riding tractors, pressure washers, tillers, and other outdoor power equipment. Use your engine model and type numbers to confirm fitment before ordering -- many flywheel keys appear similar but are engine-specific.
