GENERALDESCRIPTION OF ENGINE COMPONENTS 4 - 1 CYLINDER AND CRANKCASE The cylinder and crankcase is single piece aluminumdiecasting.Thecylinderliner,made of special cast iron, is molded into the aluminum casting. Thecrankcasehas a mountingsurfaceonthe output shaft side, where the main bearing cover is attached. (See Fig. 1.) Fig. 1 4 - 2 MAIN BEARINGCOVER The main bearing cover is aluminum an diecasting, which is mounted on the output shaft side of thecrankcase. Remove the main bearing cover to inspect inside of theengine. Pilots and bosses are machined on the cover for direct mounting of the engine onto such machines asgeneratorsandpumps. Oil gauge (fillers) are on both sides of the cover for easymaintenance. fig. 2 - 6 -
