Briggs Stratton 809785 Valve Tappet

Product Description

The BRIGGS STRATTON 809785 is a valve tappet designed as a direct OEM replacement component for small gasoline engines. The valve tappet, also called a valve lifter, sits between the camshaft lobe and the valve stem in the engine's valvetrain. As the camshaft rotates, the tappet transmits motion to open and close the intake or exhaust valve at the correct timing interval. Proper tappet condition is critical to engine performance, fuel efficiency, and long-term valve seat and stem life. This part is sourced from BRIGGS STRATTON and is intended to restore correct valvetrain operation in engines where the original tappet shows wear, pitting, or improper valve clearance.

The 809785 valve tappet is used in small air-cooled gasoline engines commonly found in walk-behind lawn mowers, riding mowers, and related outdoor power equipment. Installation is performed during engine top-end service or when a compression or valve clearance inspection reveals a worn or damaged tappet. Small engine technicians and outdoor power equipment mechanics are the primary installers of this component.

Installation Notes

Valve tappet service should be performed by a qualified small engine mechanic. Disconnect the spark plug wire and drain fuel before beginning any engine disassembly. Access to the tappets requires removal of the engine side cover or crankcase cover depending on engine configuration. After installation, always verify and set valve clearance to the engine manufacturer's specification before reassembly and return to service.
