DESCRIPTION AND OPERATION OF CAMSHAFT AND ROCKER SHAFT/ENGINE BRAKE ASSEMBLY AND RELATED PARTS

The engine uses a dual overhead camshaft and rocker shaft design. The intake and exhaust camshafts are timed to each other, through a geartrain, to the crankshaft. The camshaft housing houses the camshafts and valve train. It has internal oil passages to supply oil from the block to the camshaft and rocker bearings along with pressurized oil to the engine brake rockers via the engine brake solenoids through the exhaust shaft. The camshaft housing is made of aluminium material.

2.1 DESCRIPTION AND OPERATION OF CAMSHAFT AND ROCKER SHAFT/ENGINE BRAKE ASSEMBLY AND RELATED PARTS

2.1.1

Engine Braking

The engine uses an integral engine brake. Engine braking is controlled electronically by the engine control system with an electric solenoid. When activated, the solenoid allows oil pressure to activate a piston on the exhaust rocker arm. Engine braking is accomplished with a single exhaust valve in each cylinder. The exhaust camshaft uses a separate engine brake-only lobe that allows for double valve activation for high efficiency braking. The exhaust valve is first operated toward the completion of the intake stroke, closed during the compression stroke and opened a second time when the compression stroke is completed. The engine brake system is enabled using the following components: For EPA07 engines: □ □ □ □ □ □

2-4

Engine brake solenoid valve in front of engine applies low engine braking. Engine brake solenoid valve in rear of engine applies medium engine braking. For high, both front and rear solenoids are activated. Six exhaust rocker arms with actuator pistons. Six brake rocker arms which are actuated by the brake cam lobes. Exhaust camshaft has one brake cam lobe per cylinder.

EPA07/10 DD PLATFORM WORKSHOP MANUAL - ENGINE

The gear train on the DD Platform engines is located at the rear of the engine and has three levels. Level A consists of the outermost gears (closest to the flywheel), Level B consists of the middle gears, and Level C consists of the innermost gears (closest to the block). The gears in the gear train are both directly and indirectly driven by the crankshaft gear. □

Level A: The outermost gears include the crankshaft gear which drives the outer idler gear number one and the oil pump gear. Idler gear number four is on the crankshaft gear and the axial power turbine drives the idler gear number four when the Axial Power Turbine (APT) is creating power. The APT can add additional torque to the crankshaft through idler gear number four up to 260 N·m (192 lb·ft). These gears are all helical cut.

NOTE: On the DD13, there is no Axial Power Turbine (APT) and no Idler gear number four. The position of the idler gear number four is covered by a plate, and sealed with an O-ring. □ □

Level B: The middle gears include idler gear number one, which drives the air compressor gear and the idler gear number two. Idler gear number two drives the high pressure fuel pump and idler gear number three. These gears are all straight cut. Level C: The innermost gears include inner idler gear number three which drives idler gear number five. Idler gear number five drives both intake and exhaust camshafts. These gears are all straight cut.

Gear train noise is an indication of excessive gear lash, chipped or burred gear teeth. A rattling noise usually indicates excessive gear lash. A whining noise indicates too little gear lash. Therefore, when noise develops in a gear train, the gear train needs to be inspected.

DESCRIPTION AND OPERATION OF AIR INTAKE MANIFOLD AND RELATED PARTS

On diesel engines, the intake charge air is routed to an intake manifold that is bolted to the cylinder head with thirteen bolts. Air is then routed through the manifold and into the cylinders. The mating surfaces of the manifold and the cylinder head are machined. The intake manifold is sealed to the cylinder head with six rubber and steel gaskets. If the manifold is removed, new gaskets must be installed to maintain seal under higher boost pressure. An intake manifold air temperature sensor is installed to the intake manifold. The Exhaust Gas Recirculation (EGR) mixer, intake throttle valve and adaptor installed to the air inlet of the intake manifold. CAC ducting is installed on the intake throttle valve adaptor. For EPA07 engines, there is a pressure combination sensor in the cold boost pipe, and a temperature sensor in the intake throttle adaptor. For EPA10 engines, these sensors are combined. The combination sensor is located in the Cold Boost Pipe, and is used to measure air pressure and air temperature.

9.1

DESCRIPTION AND OPERATION OF THE DD13 TURBOCHARGER AND RELATED PARTS

Compression of air in the turbocharger causes an air mass to flow into the combustion chamber. The turbocharger consists of a turbine and a compressor which are attached to a shaft. The exhaust gas flows to the turbine wheel and causes it to turn. This turning motion is transmitted to the shaft and the compressor impeller. The intake air from the air filter is compressed by the compressor impeller and flows over a charge air pipe to the charge air cooler. The compressed air is cooled in the charge air cooler, permitting a more dense charge of air to be delivered to the engine, and therefore, engine output is increased. The charge air then passes from charge air cooler into the intake manifold. The turbocharger is mounted on the exhaust outlet flange of the engine exhaust manifold. The turbocharger is mounted on the exhaust outlet flange of the engine exhaust manifold. The advantages are as follows: □ □ □

Increases the engine performance and torque Reduction of the fuel consumption compared to a similarly powered naturally aspirated engine Reduction of emissions.

The turbocharger consists of a turbine and a compressor which are attached to a shaft. The exhaust gas flows to the turbine wheel and causes it to turn. This turning motion is transmitted to the shaft and the compressor impeller. The intake air from the air filter is compressed by the compressor impeller and flows over a charge air pipe to the charge air cooler. The compressed air is cooled in the charge air cooler, permitting a more dense charge of air to be delivered to the engine, and therefore, engine output is increased. The charge air then passes from charge air cooler into the intake manifold. The turbocharger is mounted on the exhaust outlet flange of the engine exhaust manifold.The turbocharger is mounted on the exhaust outlet flange of the engine exhaust manifold. The advantages are as follows: □ □ □

Increases the engine performance and torque Reduces fuel consumption compared to a similarly powered naturally aspirated engine Reduces emissions.

EPA07/10 DD PLATFORM WORKSHOP MANUAL - ENGINE

12.1 DESCRIPTION AND OPERATION OF DD15 AXIAL POWER TURBINE AND RELATED PARTS The Axial Power Turbine (APT) increases the efficiency and the economy of the engine by converting the thermal energy in the exhaust flow from the turbocharger into mechanical energy, delivering the resulting torque to the crankshaft. The rated speed of the turbine wheel of the APT device is about 50,000 rpm. The turbine wheel generates a torque in this range of about 10 N·m (7 lb·ft), which is increased through various gear ratios up to 260 N·m (192 lb·ft). The exhaust gas flows to the turbine wheel of the APT and drives the wheel. The rotational movement created is transmitted to the shaft of the small output gear, and from there, to the large output gear of the hydrodynamic clutch. The rotational speed is reduced because of the gear ratio between the output gear and drive gear; this gear ratio also multiplies torque output. The hydrodynamic clutch impeller is a part of the hydrodynamic clutch housing. The vanes on the impeller generate an oil flow in the hydrodynamic clutch which sets the turbine wheel of the hydrodynamic clutch into rotation and the output gear is driven over a shaft. The generated torque is transferred through the idler gear number four to the crankshaft gear. It is also possible to ensure, via the hydrodynamic clutch, that matching rotational speed takes place between the crankshaft and the axial power turbine-drive. The APT is connected to the engine oil circuit. The gears and the bearing are lubricated and cooled by the engine oil. The hydrodynamic clutch is supplied with engine oil by the hollow bearing shaft. One special aspect is the seal between the shaft and the exhaust turbine housing. The seal between these two components is formed by using two metal sealing rings which are pressed into their seat by compressed air. The pressure is regulated either by an air sealed pressure regulator or from the turbo charger compressor.

Cylinder Head Valve Springs and related components Intake and Exhaust Valves

14.1.1

Cylinder Head

The cylinder head has been designed with a compacted graphic iron material. There are two intake and two exhaust valves per cylinder. To ensure the correct bolts are used when installing the cylinder head, the bolt thread size 16 is stamped on the head of the bolt. All bolts must be tightened in the correct sequence. The valve train assembly needs to be removed in order to access the cylinder head bolts. The cylinder head has a split coolant jacket; the coolant flows around the cylinder to the inlet side of the head and then to the exhaust side. The coolant flows in the lower level of the cylinder head around the injectors and the valve seat rings. The coolant then flows around in the upper level of the cylinder head and cools the valve guides. The advantage of this design is a very even and highly effective cooling system.

There are four valves per cylinder; two intake valves and two exhaust valves. Valves are made of heat-treated alloys, with precision-ground heads and stems. Stem ends are hardened to minimize wear in contact with the valve rocker buttons. All valves are retained by valve spring caps and two-piece tapered valve locks. Valve stem oil seals are installed on both intake and exhaust valves to provide controlled valve stem lubrication while limiting oil consumption.

16.3 INSPECTION OF CYLINDER LINER Inspect as follows: 1. Inspect the cylinder liner. [a]

Check the cylinder liner for cracks or scoring. If cracks or scoring are present, replace the liner. NOTICE: Cavitation is due to poor cooling system maintenance. If uncorrected, it will eventually make holes through the liner. This can result in combustion gases blowing water out of the radiator, oil in the coolant, or when the engine is stopped will allow water to flow into the cylinder and result in major engine damage due to water in the oil or hydraulic lockup.

[b]

Check the cylinder liner for cavitation. If indication of cavitation is present, replace the liner.

[c]

Check for bore polishing; if detected, replace the cylinder liner.

2. Inspect the outside diameter of the liner. [a]

Check the liner for fretting.

[b]

If any fretting is found, remove it from the surface of the liner with a course, flat stone.

3. Inspect the liner flange in two steps: [a]

Inspect the top surface of compression seal for cracks, smoothness and flatness.

[b]

Inspect the balcony (bottom stop).

16.4 CLEANING OF THE CYLINDER LINER Clean as follows: NOTE: If using de-greasing solution to clean cylinder liner when finished, an application of clean engine oil will need to be applied to protect the cylinder liner from corrosion. 1. If cleaning a new or used liner, use a clean cloth and clean engine oil.

To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 40 psi (276 kPa) air pressure. 2. Dry the liner with compressed air. NOTICE: If the liners are not to be installed at this time, oil them lightly with clean engine lubricating oil and store them upright in a clean, dry area. Do not let the liners rest on their sides and do not store anything on top of the liners. 3. Coat the bore of the liner with clean engine lubricating oil. 4. Allow the liner to sit for 10 minutes (to allow the oil to work into the surface finish). 5. Wipe the inside of the liner with white paper towels. 6. If a dark residue appears on the towels, repeat the oiling and wiping procedure until residue no longer appears.

EPA07/10 DD PLATFORM WORKSHOP MANUAL - ENGINE

21.1 DESCRIPTION AND OPERATION OF OIL PUMP AND RELATED COMPONENTS The oil pump supplies all of the engine oil circuits with engine oil. The oil pump ensures that engine oil is available under all operating conditions, in adequate quantities, at the required pressure, and to the respective locations. A crankshaft drive gear drives the oil pump drive gear. The oil pump drive gear drives the two impellers within the oil pump housing. The rotational movement of the impellers and the design of the pump chamber suctions the engine oil from the oil pan, through oil strainer to the oil pump inlet. The engine oil is delivered under pressure to the oil pump outlet, to the oil pump pressure line and then through the return flow check valve to the main oil duct, into the engine oil circuit. The pressure regulator valve regulates engine oil pressure. The pressure regulator valve has the oil pressure applied to it from the engine oil in the main oil duct. Excess engine oil is fed by the pressure regulator valve to the suction side according to the oil pressure in the main oil duct. This regulates the engine oil pressure and reduces the operating energy input of the oil pump. High pressures in the oil circuit are avoided using the safety valve. High pressure can occur in the cold start phase of the engine if the engine oil is not yet of sufficient viscosity. The safety valve opens at a pressure >10 bar and directs part of the engine oil back into oil pan.

22.1 DESCRIPTION AND OPERATION OF CRANKCASE BREATHER The crankcase breather is located below the turbocharger on DD Platform engines, next to the starter on the right hand side of the cylinder block. The crankcase breather has the primary task of regulating the pressure in the crankcase as well as cleaning discharged blow-by gases. The gases from the crankcase contain engine oil that can lead to adverse effects on engine emission levels. The blow-by gas produced by the engine passes into the blow-by gas inlet in the crankcase breather housing. In the housing, the blow-by gas flows to the centrifuge. The centrifuge drive gear is driven by pressurized engine oil, causing the centrifuge to turn. The centrifugal force that is created causes the blow-by gas to be pushed against the inside wall of the housing. The engine oil contained in the blow-by gas runs along the inside wall downwards and flows to the outlet for the engine oil that has been separated back into the oil pan. The cleaned blow-by gas flows to the outlet for blow-by gas to the atmosphere. The crankcase breather is maintenance free for the working life of the component.

30.1

DESCRIPTION AND OPERATION OF COOLANT THERMOSTAT

Thermostat Operating Modes The coolant from the radiator and the radiator bypass mix in the thermostat housing. The thermostat regulates the temperature of this mixed flow circuit. Three different operating conditions occur due to the coolant mixed flow temperature: □ □ □

Bypass mode: When the coolant mixed flow temperature is below 87°C (188°F), the circulating thermostat is closed. The coolant circulates through the radiator bypass to the coolant thermostat. None of the flow passes through the radiator. Mixed mode: For a coolant mixed flow temperature above 87°C (188°F) to and less than 95°C (203°F), the circulating thermostat opens partially and the coolant flows at the same time through the engine radiator and the radiator bypass to the coolant thermostat . Radiator operation: When the coolant inlet temperature is above 95°C (203°F) the circulating thermostat is completely open. The coolant flows through the radiator to the coolant thermostat. None of the flow passes through the radiator bypass.

Other minor coolant loops exist in addition to those described above. The flow through these loops are unaffected by the position of the coolant thermostat. These loops include the flow through the vehicle cab heater, vehicle bunk heater, the EGR actuator, and the doser.

34.9 INSTALLATION OF RING GEAR Install the ring gear as follows: 1. Support the flywheel, ring gear side up, on a solid flat surface.

BURNS To avoid injury from burning, use lifting tools and heat-resistant gloves when handling heated components. NOTICE: Do not, under any circumstances, heat the gear over 204°C (399°F). Excessive heat may destroy the original heat treatment. Heat treating “crayons” which are placed on the ring gear and melt at a predetermined temperature, may be obtained from most tool vendors. Use of these “crayons” will ensure against overheating the gear. 2. Rest the gear on a flat metal surface. Heat the gear uniformly with an acetylene torch, keeping the torch moving around the gear to avoid hot spots. 3. Use a pair of tongs to place the gear on the flywheel with the chamfer, if any, facing the same direction as on the gear just removed. 4. Tap the gear in place against the shoulder of the flywheel. If the gear cannot be tapped into place readily so that it is seated all the way around, remove it, and apply additional heat. 5. Once the ring gear is installed, install the flywheel. 6.

39.1 DESCRIPTION AND OPERATION OF BELT DRIVE TENSIONER AND RELATED PARTS The engine uses two poly-V-belts. Since this type of belt is very flexible, a number of major assemblies can be driven by one poly-V-belt. The alternator, refrigerant compressor, and coolant pump are driven by one eight-ribbed poly-V-belt. The fan clutch and the engine fan are driven by one ten-ribbed poly-V-belt. The belt tensioners are firmly bolted onto the accessory bracket. The tensioning arms with tensioner pulleys are turned counterclockwise by the force of the springs to provide the required tension in the belts.

42.1 DESCRIPTION AND OPERATION OF CYLINDER BLOCK AND RELATED PARTS The cylinder block is the basic engine structure, establishing and maintaining the alignment of all engine working parts. The cylinder block is made from an iron material. High strength and low noise are features of the cylinder block, and is a result of the vertical and horizontal reinforcements and the design of the oil return ducts. The cylinder block lower collar design allows for a shorter distance between cylinders and a more compact design for the cylinder block. Each cylinder bore is sealed to a cylinder liner with two sealing rings: the upper sealing ring seals the upper coolant jacket to the cylinder block bore, and the lower sealing ring seals the lower coolant jacket to the cylinder block bore.

Remove cylinder liners with the cylinder liner removal tool (J–45876) before putting the block in cleaning or de-scaling baths, to avoid trapping cleaning agents in block liner seating bores. Clean the cylinder block as follows: 1. Remove all oil and water gallery plugs to allow the cleaning solution to enter the inside of the oil and water passages. Remove piston oil spray nozzles at the base of each cylinder bore. 2. Immerse and agitate the block in a hot bath of a commercial, heavy-duty alkaline solution. 3. Wash the block in hot water or steam clean it to remove the alkaline solution. 4. If the water jackets are heavily scaled, proceed as follows: [a]

Immerse and agitate the block in a bath of inhibited phosphoric acid.

[b]

Allow the block to remain in the acid bath until the bubbling action stops (approximately 30 minutes).

[c]

Lift the block, drain it and immerse it again in the same acid solution for 10 more minutes. Repeat until all scale is removed from the water jacket area.

[d]

Rinse the block in clear, hot water to remove the acid solution.

[e]

Neutralize the acid that may cling to the casting by immersing the block in an alkaline bath.

[f]

Wash the block in clean water and dry it.

EYE INJURY To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure. 5.
