(24) Rear lifting eye The six cylinders are arranged in-line. The cylinder head assembly has one inlet valve and one exhaust valve for each cylinder. The port for the exhaust valve are on the right side of the cylinder head. The port for the inlet valve are on the left side of the cylinder head. Each cylinder valve has a single valve spring.Each cylinder has a piston cooling jet that is installed in the cylinder block. The piston cooling jet sprays engine oil onto the inner surface of the piston in order to cool the piston. The pistons have a combustion chamber in the top of the piston in order to achieve clean exhaust emissions. The piston pin is off-center in order to reduce the noise level.The pistons have two compression rings and an oil control ring. The groove for the top ring has a hard metal insert in order to reduce wear of the groove. The skirt has a coating of graphite in order to reduce wear when the engine is new. The correct piston height is important in order to ensure that the piston does not contact the cylinder head. The correct piston height also ensures the efficient combustion of fuel which is necessary in order to conform to requirements for emissions.A piston and a connecting rod are matched to each cylinder. The piston height is controlled by the distance between the center of the big end bearing and the center of the small end bearing of the connecting rod. Three different lengths of connecting rods are available in order to attain the correct piston height. The three different lengths of connecting rods are made by machining the blank small end bearing of each rod at three fixed distances vertically above the centerline of the big end bearing.The crankshaft has seven main bearing journals. End play is controlled by thrust washers which are located on both sides of the number 6 main bearing.The timing case is made of aluminum. The timing gears are stamped with timing marks in order to ensure the correct assembly of the gears. When the number 1 piston is at the top center position on the compression stroke, the marked teeth on the idler gear will match with the marks that are on the fuel injection pump, the camshaft, and the gear on the crankshaft. There is no timing mark on the rear face of the timing case.The crankshaft gear turns the idler gear which then turns the following gears:
the camshaft gear
the accessory drive gear (if equipped)
the fuel injection pump gear
the water pump gearThe camshaft and the fuel injection pump run at half the rpm of the
