Briggs Stratton 495854 Standard Piston Ring Set

Product Description

The BRIGGS STRATTON 495854 is a standard-size piston ring set designed for small gasoline engines. Piston rings seal the combustion chamber, control oil consumption, and transfer heat from the piston to the cylinder wall. This set is installed by small engine technicians and experienced service professionals during engine rebuilds or overhauls where cylinder bore dimensions remain within standard tolerances. Replacing worn or broken rings restores compression, reduces oil burning, and returns the engine to proper operating condition.

This standard ring set is suited for small four-stroke gasoline engines commonly found in walk-behind lawn mowers, riding mowers, and similar outdoor power equipment. It is intended for use when the cylinder bore has been inspected and confirmed to be at standard diameter, without requiring re-boring or honing to an oversized specification.

Key Features

• Standard-size specification for use in unworn or factory-dimension cylinder bores
• Designed to restore combustion chamber sealing and reduce oil consumption
• Suitable for engine rebuild and overhaul service procedures
• OEM-style replacement engineered to match original engine tolerances

Compatibility

Designed as an OEM-style replacement piston ring set for BRIGGS STRATTON small engines. Consult the BRIGGS STRATTON parts lookup tool or engine model documentation to confirm fitment for a specific engine model and specification number before installation.

Installation Notes

Installation should be performed by a qualified small engine technician. Before disassembly, disconnect the spark plug wire and drain fuel and oil from the engine. Piston ring installation requires proper ring orientation and gap alignment per the engine service manual. Cylinder bore diameter should be measured and confirmed at standard specification before installing this ring set.
