Several constraints exist in the local market as regards the purchase and after - sales services of small stationary diesel engines used for flour milling, water pumping and generation of electricity. These constraints could be substantially addressed through local production of frequently used spares. This paper describes the local development of a production process for a cylinder head of a single cylinder diesel engine. The design drawings were used to design the pattern and core box, to mould and make the core assembly which were subsequently dried in an oven before pouring of molten metal. The cylinder head manufactured by the process was pressure tested for integrity of the water jackets and ports before machining and actual engine tests. The performance of the cylinder head during the on load and no load tests were considered normal.
