This cylinder head gasket is an original OEM part sourced directly from the manufacturer, Tecumseh. It is sold individually. A cylinder head gasket is an important piece of hardware designed for use with pieces of outdoor lawn and garden power equipment that have small engines, such as a lawn mower, a snow blower, a generator, and a wood chipper. It is compatible with products by brands such as Briggs & Stratton, Craftsman, Toro, Tecumseh, and Simplicity.The cylinder head gasket part is crucial because it serves as the seal between the engine block and cylinder head or heads. Its purpose is to seal the combustion gases within the cylinders, thereby avoiding leaking of coolant or engine oil into the cylinders. Leaks in the head gasket can be problematic because they prevent the engine from running properly and often lead to overheating.The replacement or repair process of the cylinder head gasket should be straightforward, but the user replacing the part should always be sure to wear gloves during any assembly, replacement, or installation processes. The user should also refer to the owner's manual of their equipment and any guiding diagrams that clarify the placement location.
