The making of a crank case sponsored by B.M.C.
A ladle of the molten iron is now poured into the crankcase mould. This is continued for all the prepared moulds that slowly move along a conveyor belt into a cooling area. The cooled moulds are then sand blasted to smooth the rough metal. This is done in a separate area, removes and hand finished with chisels and grindstones. After this "petaling" (sp) they are inspected and pressure tested with water.
It is then given a protective layer of paint and transported to the machine shop for final drilling and finishing. Lights of different colours flash. Drills and milling cutters. The crank shaft bearing studs are inserted. The block is again pressure tested. The top face is ground and the bores tested. The cylinder block is placed on a conveyor to the assemble section. Rods, crank shafts etc are now fitted by hand. The sump is added and the head and valves fitted. The gear box is bolted on and the finished engine is tested. Crane up over a room full of new engines. A new shiny Morris car drives towards us.
