Engines Engine Starting Cummins NOTE: Before starting the engine, read Chapter 3 in this manual for detailed information on how to read the instruments and operate the controls. CAUTION When starting a vehicle equipped with a manual transmission and clutch lock out switch, the clutch pedal must be fully depressed during the entire start sequence. Failure to do so can cause the pinion to release and re-engage, which could cause ring gear and starter pinion damage.
Engines If the outside temperature is below 60°F (16°C), fully depress the throttle, after engaging the starter. 5. Turn on the ignition switch. CAUTION Don’t crank the engine for more than 30 seconds at a time during any of the following procedures. Wait two minutes after each try to allow the starter to cool. Failure to do so could cause starter damage. WARNING Never pour fuel or other flammable liquid into the throttle body air inlet opening in an attempt to start the vehicle.
Engines Cold Start Manifold Heater WARNING Do not use starting fluid on an engine equipped with a manifold heater. Using starting fluid could cause an explosion, possibly resulting in severe personal injury and engine damage. Turn the ignition switch to the ON position. If the temperature is below 32°F (0°C), the wait-to-start indicator will come on while the manifold heater warms up. After the indicator light goes out, start the engine.
Engines The two most commonly used terms associated with preparation of equipment for low temperature operation are "winterization" and "arctic specifications." est Freightliner dealer or Cummins engine dealer, to obtain the special items required. Winterization of the engine and/or components, so that starting and operating are possible in the lowest temperature to be encountered, requires: CAUTION • Adequate lubrication with low-temperature lubricating oils.
Engines operator has an opportunity to establish conditions for the best service life by: 1. Operating as much as possible at three-quarter load. 2. Avoiding operation at engine idle speeds or at maximum horsepower levels longer than five minutes. 3. Developing the habit of closely watching the engine instruments during operation. Let up on the throttle if the oil temperature reaches 250°F (121°C), or if the coolant temperature exceeds 190°F (88°C). 4.
Engines Follow the directions in the Cummins Operation and Maintenance Manual and in this manual for trouble-free, economical vehicle engine operation. 1. Cummins diesel engines produce high horsepower and peak torque characteristics at low rpm. Because of this, it is not necessary to keep the engine "wound up" to deliver the required horsepower at the wheels. These characteristics may also result in less shifting, and make shifting at lower rpm (to peak torque) more practical. 2.
Engines control can be used on Cummins engines is 30 mph (48 km/h). 2. WARNING Do not activate the fifth wheel air slider control valve when the vehicle is in motion. Doing so could result in damage to the fifth wheel member, kingpin, cab, or trailer, and ultimately, to the drivetrain. A guard is positioned around the switch to prevent it from being accidentally activated. CAUTION Do not attempt to shift gears without using the clutch pedal when the cruise control is engaged.
Engines 2. To disengage the PTO: 2.1 Depress the foot brake pedal, trailer brake, clutch pedal, or 2.2 Flip the ON/OFF switch to OFF. To resume a previously selected engine speed, momentarily move the SET/RESUME switch to RESUME. Adjust engine speed up or down by holding the SET/ RESUME switch at SET (accelerate) or at RESUME (decelerate) until the desired speed is reached.
Engines 4. If the engine is not being used, shut it down by turning the ignition key off. High Altitude Operation Cummins Engines lose horsepower when operated at high altitude because the air is too thin to burn as much fuel as at sea level. This loss is about 3 percent for each 1000 feet (300 m) altitude above sea level for a naturally aspirated engine. Most turbocharged engines are rated for higher altitudes than naturally aspirated engines.

Clutches, Rear Axles, and Steering Clutches Clutch Operation General Information Starting the Vehicle in the Correct Gear The major reason clutches wear out too soon is excessive heat. Clutches are designed to absorb and dissipate more heat than encountered in typical operation. The temperatures developed in typical operation will not break down the clutch friction surfaces.
Clutches, Rear Axles, and Steering Riding the Clutch Pedal Engaging the Clutch While Coasting Riding the clutch pedal is destructive to the clutch, since partial clutch engagement permits slippage, generating excessive heat. Riding the clutch pedal will also put a constant thrust load on the release bearing, which can thin out the lubricant. Release bearing failures can be attributed to this type of misuse.
Clutches, Rear Axles, and Steering Fig. 6.1. After the vehicle is moving on the highway, the axle can be shifted to high range. Lubrication The release bearing should be lubricated at frequent intervals. See Group 25 of the Cargo Maintenance Manual for intervals and procedures. B CAUTION Failure to lubricate the release bearing as recommended could result in release bearing damage and damage to the clutch. Hydraulic Clutch Fluid Reservoir Checking Make sure that the clutch fluid reservoir is full.
Clutches, Rear Axles, and Steering completed the shift into the low range. Some vehicle motion is needed to ensure engagement of the axle. Meritor Drive Axles with Main Differential Lock The Meritor main differential lock is a driver-controlled traction device operated from the vehicle cab. See Fig. 6.2. A rocker switch allows the driver to lock or unlock the differential. An indicator light in the switch comes on when the differential lock is engaged.
Clutches, Rear Axles, and Steering on the accelerator to relieve torque on the gearing, allowing the differential to fully lock. The indicator light comes on when the differential is fully locked. When the differential is locked, the turning radius will increase because the vehicle understeers. See Fig. 6.3. Drive cautiously and do not exceed 25 mph (40 km/h). When the differential lock disengages, the indicator light will go off.

Brakes Air Brake System General Information A dual air brake system consists of two independent air brake systems which use a single set of brake controls. Each system has its own reservoir, plumbing, and brake chambers. The primary system operates the service brakes on the rear axle; the secondary system operates the service brakes on the front axle. Service brake signals from both systems are sent to the trailer. WARNING Do not operate the vehicle with the front brakes backed off or disconnected.
Brakes NOTE: Before a vehicle with insufficient system air pressure can be moved, the spring parking brakes must be released by applying an external air source at the gladhands, or by manually caging (manually releasing) the parking brake springs. After correcting the brake system problem, uncage the spring parking brakes before resuming normal vehicle operation. f421624 Fig. 7.
Brakes CAUTION Never apply the service and spring parking brakes simultaneously. To do so transmits excessive input force to the brake components, which could damage or cause eventual failure of brake actuating components. Meritor WABCO® Antilock Braking System (ABS), Air Brake Systems The Meritor WABCO® Antilock Braking System (ABS) is an electronic wheel speed monitoring and control system that works with the air brake system.
Brakes IMPORTANT: If any of the ABS warning lights do not work as described above, or come on while driving, repair the ABS system immediately to ensure full antilock braking capability. During emergency or reduced-traction stops, fully depress the brake pedal until the vehicle comes to a safe stop; do not pumpthe brake pedal. With the brake pedal fully depressed, the ABS system will control all wheels to provide steering control and a reduced braking distance.

The following pretrip inspection checklist helps ensure that the vehicle components are in good working condition before each trip. 6. Check the coolant level in the surge tank sight glass and check the radiator and air-to-air aftercooler cooling fins for clogging or damage. Check the radiator for coolant leaks. 7. Check the condition of the coolant hoses and heater hoses. 8.
Pretrip Inspection and Daily Maintenance 17. Inspect the fuel tank(s) and fuel line connections. If so equipped, be sure the fuel tank shutoff valves are open. 18. Check the fuel level in the fuel tank(s), and be sure the fuel cap vent area is clean. If so equipped, check the fuel/water separator for leaks. If needed, prime the fuel tank system. 19. If so equipped, check the transmission oil cooler for debris and for leaks. 20. If so equipped, inspect the fifth wheel and check it for adequate lubrication.
Pretrip Inspection and Daily Maintenance 37. Check the tire inflation pressures and inspect each tire for bulges, cracks, cuts, and penetrations. 38. Check for indications of loose wheel nuts or rim nuts and examine each rim and wheel component. After the water and oil condense, they collect near the tank drain valves. Drain the resulting emulsion as follows: WARNING 39. Check the air brake system for proper operation. 40. Test the service brakes before leaving the lot. 41.
Pretrip Inspection and Daily Maintenance particles may be in the airstream and could cause injury. 2. 1.2 Exhaust the remaining air and moisture from the system by opening the drain cocks on the bottoms of the remaining air reservoirs. Block the valves open. 1.3 Water and oil emulsion often form pockets which will not drain while compressed air is in the reservoirs. Because of these pockets, leave the valves blocked open during the first part of the pretrip inspection.
Pretrip Inspection and Daily Maintenance burning material, such as a cigarette. Always comply with the washer fluid manufacturer’s recommended safety precautions. 4. Check the front hub lubricant level if equipped with oil-lubricated wheel bearings. Observe the level of the wheel bearing lubricant in the hub cap at each end of the front axle and, if needed, fill the hubs to the level indicated on the hub cap. See Group 33 of the Cargo Maintenance Manual for recommended lubricants.
Pretrip Inspection and Daily Maintenance the exterior of the radiator or aftercooler core as often as every 200 miles (320 km). 7. Check the condition of the coolant hoses and heater hoses. Make sure the radiator inlet and outlet coolant hoses and heater hoses are pliable and are not cracking or ballooning. Replace hoses that show signs of cracking, weakening, or ballooning. Replace all hoses, including heater hoses, at the same time.

WARNING Never fill fuel tanks to more than 95 percent of their liquid capacity.
Pretrip Inspection and Daily Maintenance tank(s) to more than 95 percent of liquid capacity. Remove the air hose and tighten the fuel supply line. 18.4 Start the engine. Once the engine has started, it may run rough. If this occurs, run the engine at low idle until it runs smoothly. On vehicles equipped with a single tank, prime the fuel system, if needed. On vehicles with dual tanks, go to the next substep.
Pretrip Inspection and Daily Maintenance fifth wheel lockup may allow disengagement of the tractor from the trailer, possibly resulting in serious personal injury or death. 20.1 If the vehicle is a truck-trailer combination, be sure the trailer hitch is locked and the safety cable or chains are connected. Be sure air hoses and the light cable are connected. WARNING Check to be sure that the trailer hitch is securely connected to the truck.
Pretrip Inspection and Daily Maintenance • Fatigue or cracking of welds, which must be repaired according to the manufacturer’s specifications. WARNING Keep the fifth wheel plate lubricated to prevent binding between the tractor and trailer. A binding fifth wheel could cause erratic steering and loss of vehicle control, possibly resulting in serious personal injury or death. 20.4 Lubricate the fifth wheel top plate and other grease points at least once a week and more often in severe service.
Pretrip Inspection and Daily Maintenance such as cracks or breaks, to one leaf causes hidden damage to other leaves. Replacement of only the visibly damaged part(s) is no assurance that the spring is safe. If cracks or breaks exist on front spring assemblies in either of the two top leaves, a loss of vehicle control could occur. Failure to replace a damaged spring assembly could cause an accident resulting in serious personal injury or property damage. 23.

Make sure that both the electric horn and the air horn work. Then check the wiper and washer control. During cold weather, check the operation of the heater and defroster controls. 28.
Pretrip Inspection and Daily Maintenance Replace light bulbs or sealed beam units that are not working. 35.1 Check the clearance between the hoses, exhaust manifold, and turbocharger, or other hot spots. Excessive heat will cause the material in the hoses to deteriorate rapidly or become brittle. Provide at least six inches (150 mm) of clearance. More clearance is recommended, especially if the hose is located above the heat source. 35.2 Check for kinks, dents, or swelling of the hoses.
Pretrip Inspection and Daily Maintenance 35.6 Observe the hose cover condition, especially hoses exposed to water splash and ice. If any hose is dried out or ragged (the wire or liner is showing through the cover), replace the hose. 35.7 Inspect the front air brake lines for leaks at the fitting where they enter the air chamber. 35.9 Check the bend radii of all hoses. See Fig. 9.4.
Pretrip Inspection and Daily Maintenance 35.10 Check straight hose installations (those hoses that do not bend along their routings). Pressure changes can cause a hose to lengthen up to two percent, or shorten up to four percent. A 100-inch (2540-mm) length of hose, for example, can contract to 96 inches (2440 mm). If the hose has no slack when it is exhausted of air, replace it with one of adequate length to avoid a possible blow-off from the fitting during vehicle operation. 35.
Pretrip Inspection and Daily Maintenance caps are on every tire and that they are screwed on finger-tight. Inflate the tires to the applicable pressures, if needed. Overinflation gives the treaded surface of the tire a convex shape (Fig. 9.6). This causes extreme tire wear in the middle part of the tire since this section is primarily in contact with the road. Underinflation gives the tread surface a concave shape (Fig. 9.6).
Pretrip Inspection and Daily Maintenance and hubs and see Group 40 of the same manual for wheel and tire servicing. Replace broken, cracked, badly worn, bent, rusty, or sprung rings and rims. Be sure that the rim base, lockring, and side ring are matched according to size and type. A B WARNING C 11/03/94 f400062a A. Tire correctly inflated. B. Tire overinflated. C. Tire underinflated.
