SERIES 50 OPERATOR'S GUIDE OPERATING INSTRUCTIONS FOR A FIRST TIME START When preparing to start a new or newly overhauled engine which has been in storage, perform all of the operations listed below. Failure to follow these instructions may result in serious engine damage. Before a routine start, see the “Daily” checks for your engine in the MAINTENANCE section.
OPERATING INSTRUCTIONS FOR A FIRST TIME START of the coolant. For more detailed recommendations, refer to the How to Select Coolant section in this guide. 3. Entrapped air must be purged after filling the cooling system. To do this, allow the engine to warm up with the pressure cap removed. With the transmission in neutral, increase engine speed above 1,000 rpm and add coolant to the radiator as required. pre-lubricator.
SERIES 50 OPERATOR'S GUIDE replacing the engine lubricating oil and filters after extended storage. NOTICE: Failure to eliminate water-diluted lubricating oil may lead to serious engine damage at startup. Fuel System Checks Fill the tanks with the recommended fuel. Keeping tanks full reduces water condensation and helps keep fuel cool, which is important to engine performance. Full tanks also reduce the chance for microbe (black slime) growth.
OPERATING INSTRUCTIONS FOR A FIRST TIME START If the engine is equipped with a fuel/water separator, drain off any water that has accumulated. Water in fuel can seriously affect engine performance and may cause engine damage. Detroit Diesel recommends installation of a fuel/water separator wherever water contamination is a concern. Other Checks Check drive belts to make sure they are in good condition (not cracked, torn, worn or glazed) and are properly adjusted.
SERIES 50 OPERATOR'S GUIDE OK, both lights will go out in approximately five seconds. FLAMES, EXPLOSION AND TOXICITY To avoid injury from flames, explosion, and toxicants when using ether, the following precautions must be taken: □ Do not smoke when servicing ether system. □ Work in well ventilated area. Start the engine after the lights go out. If starting a vehicle, start the engine with foot off the foot pedal. NOTICE: If the operating lights stay on, consult with DDC Technical Service.
OPERATING INSTRUCTIONS FOR A FIRST TIME START Air Starter — Because of the limited volume of most compressed air storage tanks and the relatively short duration of the cranking cycle, it is important to make sure the engine is ready to start before activating the air starter. Start an engine equipped with an air starter as follows: 1. Check the pressure in the air storage tank. If necessary, add air to bring the pressure up to at least the recommended minimum for starting. 2.
SERIES 50 OPERATOR'S GUIDE Crankcase – If the engine oil was replaced, stop the engine after normal operating temperature has been reached. Allow the oil to drain back into the crankcase for about twenty minutes, then check the oil level. If necessary, add oil to bring the level to the proper mark on the dipstick. Use only the heavy-duty oils recommended. Refer to the How to Select Lubricating Oil section in this guide.
OPERATING INSTRUCTIONS FOR A FIRST TIME START Emergency Jump Starting The DDEC IV system operates on 12 or 24 volts DC. If an engine with an electric starting motor requires emergency jump starting, do not exceed 32 volts DC. are connected properly (positive to positive, negative to negative ground) and in the proper sequence (negative to negative ground last).
SERIES 50 OPERATOR'S GUIDE DDEC IV SYSTEM The DDEC sytem's engine-mounted Electronic Control Module (ECM) includes control logic to provide overall engine management. The ECM continuously performs self-diagnostic checks and monitors other system components. System diagnostic checks are made at ignition-on and continue throughout all engine-operating modes. Detroit Diesel Series 50 engines equipped with DDEC IV are identified by the letter “K” in the sixth position of the model number. Example: 6047GK27.
DDEC IV SYSTEM Engine Protection NOTICE: The DDEC engine protection system monitors all engine sensors and electronic components, and recognizes system malfunctions. If a critical fault is detected, the CEL and SEL illuminate. The malfunction codes are logged into the ECM's memory.
SERIES 50 OPERATOR'S GUIDE LOSS OF VEHICLE CONTROL To avoid injury from the loss of vehicle control, do not use cruise control under these conditions: □ When it is not possible to keep the vehicle at a constant speed (on winding roads, in heavy traffic, in traffic that varies in speed, etc.). Figure 6 Typical Cruise Control Switches Cruise Control may also be programmed to permit fast idle using the cruise control switches.
DDEC IV SYSTEM When the Cruise Control switch is in the ON position, cruise control is engaged by momentarily contacting the “Set/Coast” switch to the ON position. Holding the switch in the ON position allows the vehicle to slow to a lower speed. Toggling the switch will result in a one mile-per-hour (1.6 kph) decrease in vehicle speed. If cruise control has been disabled, toggling the “Resume/Accel” switch restores the vehicle to the previously set cruise speed.
SERIES 50 OPERATOR'S GUIDE Data Recording Capability DDEC Reports is a data recording capability that is standard on all DDEC IV engines. DDEC Reports contains information on driver activities, engine performance and critical incidence reporting. The information can be extracted with Detroit Diesel Diagnostic Link® 2.1 (DDDL 2.1) or later software. To perform the extraction, at least a 486 computer with a 16-MB RAM is required. DDEC IV Operation NOTE: This engine is equipped with DDEC software.
DDEC IV SYSTEM In this situation the operator may elect to override the automatic stop engine sequence by pressing the Stop Engine Override switch every 15 to 20 seconds to prevent engine shutdown from occurring. Stop Engine Light NOTE: For some applications, holding down the Stop Engine Override switch will not prevent the engine shutdown sequence. You must continue to reset the automatic shutdown system by pressing the Stop Engine Override switch at intervals of approximately 15 to 20 seconds.
SERIES 50 OPERATOR'S GUIDE The malfunction code recorded in the computer memory will remain until it is erased by a technician. Figure 7 Diagnostic Data Reader J 38500 Once the malfunction has been corrected, the DDEC system will return the engine to normal operation. The DDR can distinguish between codes now active and those stored in the ECM memory (inactive). Figure 8 The malfunction code can also be obtained by the operator.
DDEC IV SYSTEM Active Codes – The active codes will be flashed on the SEL in the order of most recent to least recent occurrence based on engine hours. If there are no active codes, a code 25 will be flashed. Inactive Codes – The inactive codes will be flashed on the CEL in the order of most recent to least recent occurrence based on engine hours. If there are no inactive codes, a code 25 will be flashed. Only One Light Flashes at a Time – Only one light will be flashing codes at any time.

SERIES 50 OPERATOR'S GUIDE DDEC IV ENGINE DRIVING TIPS Driving with an electronically controlled engine feels different from driving with a mechancially governed engine. Accelerating the Vehicle Engine response versus pedal movement may feel different from the mechanical-governed engine you were driving. The electronic foot pedal assembly (EFPA) was designed to communicate “percentage” foot pedal travel to the engine's electronic control module (ECM).
DDEC IV ENGINE DRIVING TIPS Turn the switch ON to energize the system. When you reach your road speed, press the “Set” switch to activate cruise control. The cruise light will come on. To increase road speed in one mile-per-hour (1.6 kilometer-per-hour) increments, press the “Resume/Accel” switch. To reduce road speed, press and hold the “Set/Coast” switch until the lower speed is reached. Cruise control is deactivated by slightly depressing the service brakes, clutch pedal, or trailer brake.
SERIES 50 OPERATOR'S GUIDE Engine Brakes and Cruise Control If your engine is equipped with both cruise control and engine brake retarders, the engine retarders can operate automatically while you are in cruise control. If the cruise control/engine brake function is turned ON in the ECM (electronic control module) programming, the engine retarders will come on “low” when your set road speed increases a few miles-per-hour (kilometers per hour) above your cruise set speed.
DDEC IV ENGINE DRIVING TIPS If you decide to drive at lower rpm's for improved fuel economy, don't let different engine noises throw you off guard. The Series 50 sounds quiet at 1400 rpm, almost as if it had quit pulling. Don't believe it! If you had a boost gage to look at while driving, you would notice the turbocharger maintaining steady intake manifold pressure, even as rpm's fall.
SERIES 50 OPERATOR'S GUIDE ENGINE BRAKE SYSTEM Certain Series 50 vehicle engines are equipped with engine brakes, commonly referred to as retarders. Before operating the vehicle, you must familiarize yourself with the retarder system to obtain optimum benefit from it. Engine brake control systems may vary slightly, depending on the engine brake configuration and cab design. However, basic operator controls are similar for all models.
ENGINE BRAKE SYSTEM After it is switched on, the engine brake system is automatically activated each time you remove your feet completely from the clutch pedal and throttle. The engine brake automatically deactivates itself when you press the clutch pedal while shifting gears.
SERIES 50 OPERATOR'S GUIDE Driving on Flat, Dry Pavement Use the following guidelines when driving on flat, dry pavement: 1. If driving on flat, dry, open stretches with a light load and greater slowing power is not required, place the progressive braking switch in the LOW position. 2. If you find you are still using the service brakes, move the switch to a higher position until you do not need to use the service brakes to slow the vehicle down. 3.
ENGINE BRAKE SYSTEM PERSONAL INJURY Failure to keep the vehicle within safe control speed limits while descending a grade may result in loss of vehicle control, which could cause personal injury. 4. Check your progressive braking switch often for proper position, since road conditions can change quickly. Never skip a step when operating the progressive braking switch. Always go from OFF to LOW and then to a higher position when on slippery roads.
SERIES 50 OPERATOR'S GUIDE OFF immediately and do not activate it until road conditions improve. LOSS OF VEHICLE CONTROL To avoid injury from loss of vehicle control, do not activate the Engine Brake system under the following conditions: □ On wet or slippery pavement, unless the vehicle is equipped with ABS (anti-lock braking system) and you have had prior experience driving under these conditions. Check your progressive braking switch often for proper position, since road conditions can change quickly.
ENGINE SYSTEMS ENGINE SYSTEMS The engine system are the following: Fuel System The fuel system consists of the DDEC, fuel injectors, fuel manifolds (integral with the cylinder head), fuel pump, a cooling plate for the ECM on non-automotive engines, primary and secondary fuel filters, and the necessary connecting fuel lines.
SERIES 50 OPERATOR'S GUIDE MAINTENANCE The following is intended as a guide for establishing preventive maintenance intervals. The recommendations given should be followed as closely as possible to obtain long life and optimum performance from your engine. Maintenance intervals indicated are time (hours) of actual operation.

HOW-TO SECTION Detroit Diesel markets a OATinhibited ethylene glycol coolant, DDC Power Cool Plus, which contains all the required additives. If a non-DDC OAT antifreeze is used, it must conform to TMC 338 specification. Do not add extender to new OAT antifreeze or coolant. should be mixed at 7.5% – 10% by volume with water. For a list of Power Cool products, refer to section SPECIFICATIONS in this guide. Traditional SCA (Power Cool 3000) can also be used to protect the engine.
SERIES 50 OPERATOR'S GUIDE Coolants Not Recommended tap water is preferred. High levels of dissolved chlorides, sulfates, magnesium, and calcium in some tap water causes scale deposits and/or corrosion. These deposits have been shown to result in water pump failures and poor heat transfer, resulting in overheating. If tap water is used, the mineral content in the water must be below the maximum allowable limits listed in Table 24.
HOW-TO SECTION Methyl Alcohol-Based Antifreeze — This coolant must not be used because of its effect on the non-metallic components of the cooling system and its low boiling point. Methoxy Propanol-Based Antifreeze — This coolant must not be used because it is not compatible with the fluoroelastomer seals found in the cooling system. Glycol-based Coolants Formulated For HVAC — These coolants formulated for heating/ventilation/air conditioning (HVAC) should not be used.

Detroit Diesel Power Trac 3–Way Coolant Test Strips should be used to measure nitrite and glycol concentrations. Part numbers are Listed in Table 46. Cavitation/corrosion is indicated on the strip by the level of nitrite concentration. Freeze/boil over protection is determined by glycol concentration. 2.
SERIES 50 OPERATOR'S GUIDE Need-Release Coolant Filters (Non-OAT Systems) Spin-on coolant filters are available for Detroit Diesel engines. Membranes in the filters release SCAs before the coolant approaches a corrosive condition, protecting the engine from corrosion. The elements release the SCA charge as needed, as opposed to the maintenance SCA elements, which instantaneously release the SCA charge.
HOW-TO SECTION Coolant Extender Inhibitor Additive for “OAT” Coolant The inhibitors in OAT coolant must also be maintained, but less often than traditional SCA-type coolants. A portable test is available to test the levels of OAT inhibitors in coolant. Where this is not used, fleet testing has determined that a OAT coolant extender package should be added to the coolant at 300,000 miles (480,000 km), two (2) years, or 5,000 hours, whichever comes first.
SERIES 50 OPERATOR'S GUIDE Detroit Diesel Cooling System Maintenance Products The following products are available to use for cooling system maintenance. Power Cool SCAs — Power Cool SCAs are water-soluble chemical compounds. These products are available in coolant filter elements, liquid packages, and in fully formulated Power Cool antifreeze.

SERIES 50 OPERATOR'S GUIDE ENGINE STORAGE When an engine is to be stored or removed from operation for a period of time, special precautions should be taken to protect the interior and exterior of the engine, transmission and other parts from rust accumulation and corrosion. The parts requiring attention and the recommended preparations are given below.
ENGINE STORAGE Extended Storage (More than 30 Days) Refer to the How to Select Coolant section. NOTE: If an antifreeze solution is not required during storage, flush the cooling system with a good soluble oil (3% – 5% by volume) rust inhibitor to prevent rusting of the outside diameter of the cylinder liners. 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. 6.
SERIES 50 OPERATOR'S GUIDE 6. Drain the fuel tank. Refill with enough clean No. 1 diesel fuel or pure kerosene to permit the engine to operate for about ten (10) minutes. If draining the fuel tank is not convenient, use a separate, portable supply of recommended fuel. NOTE: If engines are stored where condensation of water in the fuel tank may be a problem, additives containing methyl carbitol or butyl cellusolve may be added to the fuel. Follow manufacturer's instructions for treatment.
ENGINE STORAGE should be sealed off with moisture-resistant tape. 13. Apply a non-friction rust preventive compound to all exposed engine parts. If convenient, apply the rust preventive compound to the engine flywheel. If not, disengage the clutch mechanism to prevent the clutch disc from sticking to the flywheel. NOTE: Do not apply oil, grease or any wax-base compound to the flywheel. The cast iron will absorb these substances, which can “sweat” out during operation and cause the clutch to slip. 14.
SERIES 50 OPERATOR'S GUIDE NOTICE: Do not use plastic sheeting for outdoor storage. Plastic is fine for indoor storage. When used outdoors, however, enough moisture can condense on the inside of the plastic to rust ferrous metal surfaces and pit aluminum surfaces. If a unit is stored outside for any extended period of time, severe corrosion damage can result. The stored engine should be inspected periodically.
ENGINE STORAGE 9. Install and connect the battery. Make sure the average specific gravity of the battery is 1.260 or higher. Charge the battery, if necessary. 10. Service the air cleaner, if required. 11. Transmission: Follow the manufacturer's recommendations covering the return of the transmission to service. 12. Power Take-Off: If equipped, follow the manufacturer's recommendations covering the return of the power take-off to service.
