Briggs Stratton 499962 Piston Assembly 020 Oversize

Product Description

The BRIGGS STRATTON 499962 is an 020 oversize piston assembly designed as a direct replacement component for small gasoline engines used in lawn and garden power equipment. This assembly provides the core reciprocating component within the engine cylinder, converting combustion pressure into crankshaft rotation. The 020 designation indicates the piston is machined 0.020 inches over the standard bore diameter, making it the correct choice when a cylinder has been bored out to restore proper clearance after wear. Installation is typically performed during an engine rebuild or top-end overhaul.

This piston assembly is intended for use in Briggs Stratton small engines found in walk-behind lawn mowers, riding tractors, and other residential and light commercial lawn and garden equipment. The 020 oversize specification suits engines where the cylinder bore has been resized by a qualified technician to remove scoring, out-of-round wear, or taper. Proper bore sizing must be confirmed before ordering this oversize component.
