Engine Description
Note: When you are ordering new parts, refer to the engine identification number in order to receive the correct parts.The 3003, 3013, 3014 and 3024 engines are diesel engines that are controlled with a mechanically actuated fuel injection pump. The engine cylinders are arranged in-line.The cylinder head assembly has one inlet valve and one exhaust valve for each cylinder. Each cylinder valve has a single valve spring. The pistons have two compression rings and an oil control ring.It is important to ensure the correct piston height so 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.The crankshaft for a three cylinder engine has four main journals. The crankshaft for a four cylinder engine has five main journals. End play is controlled by thrust washers that are located on the rear main bearing.The timing gears are stamped with timing marks in order to ensure the correct alignment of the gears during assembly. When the No. 1 piston is at top center compression stroke, the teeth that are stamped on the crankshaft gear and the camshaft gear will be in alignment with the idler gear.The crankshaft gear turns the idler gear which then turns the following gears: the camshaft gear and the gear for the lubricating oil pump.The fuel injection pump is mounted on the cylinder block. The fuel injection pump is operated by the camshaft lobes. The fuel transfer pump is located on the right hand side of the cylinder block. The fuel transfer pump is operated by the camshaft lobes.The fuel injection pump conforms to requirements for emissions. Adjustments to the fuel injection pump timing and high idle should only be made by trained personnel. The fuel injection pumps have mechanical governors that control the engine rpm.A gerotor type engine oil pump is located in the center of the idler gear. The engine oil pump sends lubricating oil to the main oil gallery through an oil relief valve. The oil relief valve is located on the right side of the cylinder block. The rocker arms receive pressurized oil through an externally located oil line. The oil line runs from the main oil gallery to the cylinder head.Coolant from the bottom of the radiator passes through the belt driven centrifugal water pump. The coolant is cooled by the radiator and the temperature is regulated by a water temperature regulator.Lifting the Engine
Failure to follow recommended procedures for handling or transporting engines can lead to engine damage.To avoid possible engine damage, use the following procedure.
When you are lifting or moving the engine, use the following procedures in order to prevent engine damage.
Do not tilt the engine to an extreme angle unless the lubricating oil is first drained from the oil pan.
Do not turn the engine onto a side or an end surface unless the lubricating oil is first drained from the oil pan.
If the oil is not drained
