Brake System Air Brake System Brake System General Information A dual air brake system consists of two independent air systems that use a single set of brake controls. Each system has its own reservoirs, 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.
Brake System actually improves vehicle control when the tractor is in bobtail mode. When the tractor is towing a trailer, the rear brake chambers will receive full (normal) application air pressure. When parking a vehicle attached to a trailer that does not have spring parking brakes, apply the tractor parking brakes. Chock the trailer tires before disconnecting the vehicle from the trailer.
Brake System Do not use the spring parking brakes during freezing temperatures if the service brakes are wet. To do so could cause them to freeze. If the brakes are wet, drive the vehicle in low gear and lightly apply the brakes to heat and dry them. If the trailer is not equipped with spring parking brakes, pulling out the parking brake valve applies the tractor spring parking brakes and the trailer service brakes.

Brake System Automatic Traction Control warning lights go out if all of the tractor’s ABS components are working. Vehicles with electronic engines and ABS may have Automatic Traction Control (ATC). On these vehicles, the ATC system automatically limits wheel spin during reduced-traction situations. In normal braking applications, the standard air brake system is in effect.
Brake System • The HI/MED/LO (in some cases HI/LO) engine brake level switch on the dash, controls the amount of engine braking. 1 2 A driver may descend slower than control speed by selecting a lower gear, being careful not to overspeed the engine. Occasional deactivation of the engine brake may be necessary to maintain the designated road speed under these conditions. Below a set engine temperature when the engine is cold, the brake may be disabled depending on the brake type.
Brake System will automatically turn itself back on once the wheel slip is no longer detected. 12.

Manual Transmissions and Clutch Eaton Fuller® Transmission, Operating Tips Eaton Fuller Splitter and Range-Shift Transmissions Refer to the Eaton website for additional information, www.roadranger.com. Combination splitter and range-shift transmissions allow the choice of two splitter ratios in each gear, as well as the additional ratios provided by a low range and a high range.
Manual Transmissions and Clutch Eaton Fuller 13-Speed Splitter and Range-Shift Transmissions Eaton Fuller 13-speed transmissions have thirteen forward speeds and two reverse speeds. Each transmission consists of a 5-speed front section and a 3-speed auxiliary section. The auxiliary section contains low- and high-range ratios, plus a splitter gear. See Fig. 14.1 for the shift pattern. Hi R Lo 5 5 Dir OD 1 LOW 2 6.
Manual Transmissions and Clutch Eaton Fuller 18-Speed Splitter and Range-Shift Transmissions Eaton Fuller 18-speed transmissions have eighteen forward speeds and four reverse speeds. Each transmission consists of a 5-speed front section and a 4-speed auxiliary section. The auxiliary section contains low- and high-range ratios, plus a splitter gear. See Fig. 14.2.

Manual Transmissions and Clutch (4th to 3th, etc.); single-clutch during split shifts (4th direct to 3rd overdrive, etc.). Eaton Fuller 10-Speed Range-Shift Transmissions Eaton Fuller 10-speed transmissions have ten selective, evenly-spaced forward ratios. Each transmission consists of a 5-speed front section, and a 2-speed auxiliary section. The ten forward speeds are obtained by twice using a 5-speed shift pattern: the first time in low range, the second time in high range. See Fig. 14.
Manual Transmissions and Clutch NOTICE Do not allow the clutch to slip longer than two seconds. Clutch slippage for longer than two seconds may severely damage the clutch disc, pressure plate, or flywheel. Damage caused by clutch slippage due to improper break-in is not warrantable. During initial operation of a new vehicle or a vehicle with a new clutch, check for clutch slippage during acceleration. If the clutch slips, decelerate until the clutch does not slip.
Manual Transmissions and Clutch hill. Slipping the clutch on a hill to maintain vehicle position will quickly damage the clutch assembly. Coasting Coasting with the clutch pedal depressed and the transmission in a low gear can cause high driven disc speed. The clutch speed can be much higher under these conditions than when the engine is driving the clutch. This condition creates a hazardous situation due to the lack of vehicle control and due to the high clutch disc speed.
Manual Transmissions and Clutch Lubricating the Clutch Release Bearing NOTICE Failure to lubricate the release bearing and linkage as recommended could result in release bearing and clutch damage. On vehicles equipped with a greased release bearing, the release bearing should be lubricated at regular intervals. See the Century Class Trucks Maintenance Manual for intervals and procedures. 14.

Automated Transmissions Freightliner SmartShift Shift Control 5 SmartShift accepts driver requests for transmission functions and transmits them through hard wiring to the transmission control unit (TCU). SmartShift is a true shift-by-wire system. SmartShift offers two main advantages over conventional transmission control devices. Without a floormounted shift control, usable cab space is increased.
Automated Transmissions 6. Release the service brake and apply the accelerator. Engine Shutdown 1. Select Neutral on the shift control. NOTE: If the gear display does not show a solid "N", neutral has not yet been obtained. Neutral should always be reached before powering down an UltraShift PLUS, except in cases of emergency. 2. Set the parking brake. 3. Turn off the ignition, and shut down the engine.
Automated Transmissions gear, select Neutral, apply the service brakes, and select the desired mode again. Manual Mode Override The system is equipped with a manual mode override function. If the vehicle is being "back driven" (for example, descending a grade and vehicle speed exceeds engine speed) and the engine speed is excessively high, the system will upshift automatically.
Automated Transmissions 3. Release the accelerator pedal. The vehicle will continue moving at governed low engine idle speed. Exiting Creep Mode To exit Creep Mode, apply the accelerator pedal to accelerate temporarily, or select a higher gear in Manual Mode. (Creep Mode can be resumed in the selected gear by releasing the accelerator pedal.) NOTE: The transmission will exit Creep Mode if the engine lugs 150 rpm below the governed low engine idle speed.
Automated Transmissions actuate the braking system increases with throttle: low throttle allows the system to brake the wheels earlier; heavy/full throttle raises the point of the acceptable wheel slip. Load-Based Shifting The UltraShift PLUS system is adaptive and will change the shift points based on grade, engine RPM, throttle position, and vehicle load. After changing loads or powering up, the system needs to relearn these inputs for the first few shifts to make the proper adjustments.
Automated Transmissions In either mode, the gear indicator displays the current gear. See Fig. 15.3. A shift request will be refused if the selected gear would cause engine overspeed or excessive lugging. If the vehicle is stopped while in drive, pull up or push down on the SmartShift control lever to change the starting gear. 1 01/23/2019 f611581 NOTE: The gear indicator displays the current gear. In this example, it displays twelfth gear. 1. Gear Display Fig. 15.
Automated Transmissions starting gear other than the preprogrammed default starting gear. Upshifting NOTE: With the transmission in drive in the automatic mode, upshifts require no driver interaction. 1. With the transmission in drive in the manual mode, pull the control lever up (towards the driver) to upshift. If the requested gear is available, the transmission will upshift and the new gear will display on the gear indicator.
Automated Transmissions NOTE: Reverse may be engaged below a programmable forward speed in order to rock the vehicle. If reverse is selected above the programmed forward speed, an audible warning will sound indicating that the gear is not available. Low Gear Operation Use low (L) to maximize engine braking and minimize the use of the brake pedal. It is most useful when descending steep hills or when coming to a stop. Engine speed will be increased by 200 rpm and shift points will be offset by 200 rpm.

Fifth Wheels Fifth Wheels, General Information Fifth Wheel Lubrication WARNING WARNING Do not use any fifth wheel that fails to operate properly. Doing so may cause loss of vehicle control, possibly resulting in severe personal injury or death. Air-Suspension Dump Valve The air-suspension dump valve may be used to adjust the tractor height to aid with coupling to or uncoupling from a trailer. See Fig. 17.1.
Fifth Wheels prevent from hitting the kingpin too hard, then resume backing slowly until the fifth wheel locks. NOTICE On a standard fifth wheel, the fifth wheel must lift the trailer. Attempting to couple at the wrong height may cause improper coupling, which could result in damage to the fifth wheel or kingpin. 5. On a low-lube fifth wheel, do not lift the trailer as this may damage the fifth wheel plate. Adjust the trailer height if required.
Fifth Wheels 6. NOTICE Always make sure the connection hanger keeps the trailer air hoses and electrical cables positioned so that they do not rub on anything. Rubbing may wear through hoses or cables, resulting in air leaks, or exposed or broken wires, potentially affecting trailer brake or electrical systems. 11. Charge the air brake system with air, checking that the air connections do not leak.
Fifth Wheels The fifth wheel is now in the lock position and is ready for uncoupling. As the tractor pulls away from the trailer the kingpin forces the jaw to rotate, contacting the lock. Continued rotation of the jaw forces the lock to move outward, and drops the upper rod back into the slot. The wheel is now ready for coupling. 6.3 7. Jost: Pull the retractable release handle out, then secure it in the open position with the catch. See Fig. 17.5.
Fifth Wheels Preparing the Trailer for Uncoupling Fifth Wheel Slide Before using the air valve to unlock a fifth wheel kingpin, prepare the trailer as follows. 1. Apply the tractor and trailer parking brakes. 2. Chock the trailer tires. 3. Lower the trailer landing gear until the weight is removed from the fifth wheel. 4.
