Tecumseh 510349 Cylinder Head Gasket

Product Description

The TECUMSEH 510349 is a genuine OEM cylinder head gasket designed for lawn and garden equipment engines. It forms a seal between the engine block and the cylinder head, preventing combustion gases and coolant from mixing and maintaining proper compression. This is a direct-replacement part sourced from the original equipment manufacturer, ensuring dimensional accuracy and material consistency with the factory-installed gasket. A licensed small-engine technician or experienced service professional typically handles this repair as part of a top-end rebuild or head gasket replacement service.

This cylinder head gasket is intended for use in lawn and garden equipment engines. It is suited to residential and light commercial outdoor power equipment applications where the original gasket has failed, resulting in compression loss, overheating, or oil and combustion gas leakage past the head. Compatible models include 143982070, TC300-3218J, 143961670, 143961672, TC300-3204J, 200731031, 143962070, 143012070, 143002072, 143992070, 143971670, 143941600, TC300-3173G, TC300-3192F.

Installation Notes

Allow the engine to cool completely before beginning work, and disconnect the spark plug wire to prevent accidental startup. Remove the cylinder head bolts, old gasket material, and clean both mating surfaces before installing the new gasket. A small-engine technician should perform this repair, following the engine manufacturer's torque sequence guidance for head bolt reinstallation. Verify the spark plug wire remains disconnected throughout the procedure.
