Crankshaft
The crankshaft changes the combustion forces in the cylinders into usable rotating torque which powers the machine. There is a timing gear at each end of the crankshaft which drives the respective timing gears.The bearing surfaces on the crankshaft get oil for lubrication through passages drilled in the crankshaft.Vibration Damper
The twisting of the crankshaft, due to the regular power impacts along its length, is called twisting (torsional) vibration. The vibration damper is installed on the front end of the crankshaft. It is used for reduction of torsional vibrations and stops the vibration from building up to amounts that cause damage.
CROSS SECTION OF A TYPICAL RUBBER VIBRATION DAMPER
1. Flywheel ring. 2. Rubber ring. 3. Inner hub.The rubber damper is made of a flywheel ring (1) connected to an inner hub (3) by a rubber ring (2). The rubber makes a flexible coupling between the flywheel ring and the inner hub.The viscous damper is made of a weight (1) in a metal case (3). The small space (2) between the case and weight is filled with a thick fluid. The fluid permits the weight to move in the case to cause a reduction of vibrations of the crankshaft.
CROSS SECTION OF A TYPICAL VISCOUS VIBRATION DAMPER
1. Solid cast iron weight. 2. Space between weight and case. 3. Case.Electrical System
The electrical system has three separate circuits: the charging circuit, the starting circuit and the low amperage circuit. Some of the electrical system components are in more than one circuit. The battery (batteries), circuit breaker, ammeter, cables and wires from the battery are all common in each of the circuits.
The disconnect switch must be in the ON position to let the electrical system operate. There will be damage to some of the charging circuit components if the engine is running with the disconnect switch in the OFF position.
The charging circuit is in operation when the engine is running. An alternator makes electricity for the charging circuit. A voltage regulator in the circuit controls the electrical output to keep the battery at full charge.The starting circuit is in operation only when the disconnect switch is put in the ON position and the start switch is activated.The starting circuit has a glow plug for each cylinder of the diesel engine. Glow plugs are small heating units in the precombustion chambers. Glow plugs give aid for ignition of the fuel when the engine is started in temperatures that are low.The low amperage load circuit and the charging circuit are both connected to the same side of the ammeter. The starting circuit connects to the opposite side of the ammeter.Charging System Components
Alternator (Prestolite) 2P1204
2P1204 ALTERNATORThe alternator is driven by two V type belts from the fan pulley. It is a 24 volt, 19 ampere unit with a regulator which has no moving parts (solid state) installed on the side opposite the pulley. The alternator is made up of the following parts: head assembly on the drive end, rotor assembly, stator assembly, rectifier and heat removal assemblies, brush
