Top Gasket Set U5LT1202, 4224635M91 Perkins

The U5LT1202 Top Gasket Set is a genuine AGCO upper engine sealing kit engineered for Perkins 1004 Series 4-cylinder diesel engines. Designed for cylinder head overhaul and top-end engine rebuilding applications, this comprehensive gasket set provides reliable sealing performance across critical engine components exposed to high temperature, combustion pressure, engine oil, and coolant circulation. Manufactured to original AGCO and Perkins specifications, the kit includes essential upper engine sealing components such as the cylinder head gasket, valve cover gasket, intake manifold gasket, exhaust manifold gasket, valve stem seals, turbo gasket, filter head gasket, O-rings, and specialized sealing washers required during professional engine servicing and reassembly. The U5LT1202 gasket set is engineered to maintain leak-free sealing between the cylinder head, engine block, manifold assemblies, and auxiliary upper engine components. High-quality composite gasket materials and heat-resistant elastomer seals help maintain stable compression, proper oil pressure, and efficient coolant circulation under demanding agricultural and industrial operating conditions. Precision-manufactured sealing surfaces compensate for thermal expansion, vibration, and microscopic irregularities between mating engine components, helping prevent oil seepage, coolant leaks, and compression loss. Designed as a direct OEM-fit solution, this top gasket set supports reliable engine performance, simplified installation, and long-term durability for Perkins-powered machinery operating in heavy-duty environments. Please note that this kit is intended for upper engine overhaul applications and does not include lower engine seals such as oil sump gaskets or front/rear crankshaft oil seals.
