How does crankshaft service and repair during an engine overhaul on Mercury Cougar?

During crankshaft maintenance and servicing the cleaning and inspection process applies to all parts starting from the crankshaft and crankshaft bearings extending to the camshaft and crankshaft bearings up to the cylinder head together with valve train components (values, seats, and springs) and the piston, piston pin, connecting rod and cylinder block and bore. During disassembly and assembly procedures the subassemblies are serviced for cylinder heads as well as pistons and their pin and connecting rod components. The engine service and repair procedures include both engine disassembly and assembly phases. A missing separate service procedure for internal components from a manufacturer indicates their omission of such guidelines. Check the engine service and repair guidelines to obtain the current list of available service procedures.
