Briggs Stratton 499631 Standard Piston Ring Set

Product Description

The BRIGGS STRATTON 499631 is a standard-size piston ring set designed for small gasoline engines used in outdoor power equipment. Piston rings seal the combustion chamber, control oil consumption, and transfer heat from the piston to the cylinder wall. This set restores proper compression and oil control in worn engines, making it a core component in engine rebuilds and top-end overhaul work. Installation requires a seasoned small-engine technician familiar with bore measurement, ring gap specification, and proper ring orientation during assembly.

This ring set is suited for standard-bore engine rebuilds where the cylinder has been measured and confirmed within factory tolerances without requiring overbore. It is used in residential and light commercial outdoor power equipment applications including lawn mowers, riding tractors, generators, and similar Briggs Stratton-powered units. Technicians performing engine rebuilds or compression restoration work will find this a direct OEM-style replacement to bring worn engines back to spec.

Key Features

• Standard size fit for cylinders at original factory bore diameter
• Restores combustion chamber sealing and compression integrity
• Controls oil consumption by sealing the piston-to-cylinder clearance

Compatibility

Designed as an OEM-style standard-bore piston ring replacement for compatible Briggs Stratton small gasoline engines. Verify engine model, type, and code numbers before ordering to confirm fitment.

Installation Notes

Installation should be performed by a qualified small-engine technician. Before beginning, disable the spark plug and drain all fluids as required for safe engine disassembly. Measure cylinder bore with an inside micrometer before installation to confirm the cylinder is within standard tolerance and has not been overbored. Follow manufacturer ring gap and orientation specifications during assembly, as improper installation can result in oil burning, poor compression, or engine damage.
