Engine Gasket Set
Genuine Midwest Engine part
By: Midwest Engine
Part Number: 590508

Engine gaskets are designed to seal and insulate various parts of the engine. Because they are subject to high heat and constant pressure, they can wear down and degrade over time. This can affect the seal of the engine and ultimately inhibit performance. If gaskets are left in disrepair, it can even create bigger problems in the engine. Therefore, a full replacement will be necessary. Gasket maintenance and replacement are considered parts of routine maintenance for lawn equipment. There are several of these gaskets found on lawn and garden equipment engines, and when more than one is faulty, it may be best to replace the entire set. This genuine set can be the perfect solution for compatible engines. This genuine OEM engine gasket set is designed to exact manufacturer standards and comes from Briggs & Stratton. This kit is designed for use with generator and lawn mower engines on select units from Toro and Briggs & Stratton. There are more than 150 units that can take this gasket set. These gaskets are made of durable composite materials and this set is sold individually, with a total of 18 gaskets included. Be sure to allow the engine to cool before replacing gaskets and always use the appropriate tools to prevent damage during replacement.
