Haynes HM04R Build Your Own Internal Combustion Engine Kit Assembly Manual
This is the assembly manual for the Haynes HM04R "Build Your Own Internal Combustion Engine" kit, a simplified working model of a four-stroke petrol car engine intended for builders aged 10 and over under adult supervision. The manual explains what the kit contains, how to prepare the parts before assembly, and lists all components including the Engine 2000, electric motor unit, distributor, throttle body, valve springs, screws, shafts and the included screwdriver.
The main section gives step-by-step instructions for building the engine, starting with the sump pan and piston/connecting rod assemblies, then the cylinder block, valves, springs, rocker arms and cylinder head. Later chapters explain how a petrol engine works, basic engine terms, and how to keep a car engine healthy while reducing pollution and saving on fuel. Builders who complete the model can download a Haynes Engineer Certificate from www.haynes.co.uk/engine.
