Parts for Briggs & Stratton 31P677-1517-B1: Engine Sump Parts

The crankcase is a metal case over the crankshaft of an engine. It is essential to the operation of the engine as it shields the crankshaft and rods from any debris. It also ensures the pressurization of the chamber and helps to keep pistons and oil moving properly. The crankshaft gasket is part of what keeps the seal and allows the engine to function. It can wear with time or even become dry and cracked. It will cause oil leakage, smoke, and even engine failure. This is a genuine OEM crankcase gasket for lawnmowers, lawn tractors, and small engines produced by Toro, Cub Cadet, MTD, Briggs & Stratton, and Simplicity. It comes as an individual component.
