AIR SYSTEM AIR SYSTEM Introduction WARNING! Do not attempt to modify, alter, repair or disconnect any component of the air system. Repairs or modifications to the air system, other than what is described in this section, should only be performed by an authorized dealer. Failure to comply may result in death or personal injury. WARNING! WARNING! Prior to the removal of any air system component, always block and hold the vehicle by a secure means other than the vehicle's own brakes.
AIR SYSTEM WARNING! WARNING! Never attempt to disassemble a component until you have read and understood recommended procedures. Some components contain powerful springs and injury can result if not properly disassembled. Use only proper tools and observe all precautions pertaining to use of those tools. Failure to comply may result in death, personal injury, equipment or property damage. Completely bypassing a Bendix® AD-IS air dryer will bypass the system’s pressure protection valves.
AIR SYSTEM WARNING! If the supply and service tanks are not drained at the recommended frequency, water could enter the air lines and valves. This could cause corrosion or blockage, which could compromise the brake system safety and potentially cause an accident involving death or personal injury. Daily Periodically • Drain moisture from the supply and service air tanks. • • Operate air devices to circulate lubricants within the unit.
AIR SYSTEM Twice a Year Air Dryer • The function of the air dryer is to collect and remove air system contaminants in solid, liquid and vapor form before they enter the brake system. It provides clean, dry air to the components of the brake system, which increases the life of the system and reduces maintenance costs. • Maintain the air compressor to prevent excessive oil by-pass. See your maintenance manual for details. Replace worn seals in valves and air motors as they are needed.
AIR SYSTEM and non-compressing cycle) in a normal fashion or it may be due to excessive leaks in the air system. • • In areas where more than a 30° F (17° C) range of temperature occurs in one day, small amounts of water can accumulate in the air brake system due to condensation. Under these conditions, the presence of small amounts of moisture is normal and should not be considered as an indication that the dryer is not performing properly. An outside air source has been used to charge the air system.
AIR SYSTEM components that have typically been installed separately on the vehicle (see below for components/areas affected): • Pressure protection valves • Safety valve • Governor and plumbing • Plumbing of the front and rear service air tanks • 5 Air Tanks basis. Operate air devices daily to circulate lubricants within the unit. Periodically: Clean filter screens ahead of the valves by removing the screens and soaking them in solvent.
AIR SYSTEM Air Gauges and Air Leaks CAUTION Do not use penetrating oil, brake fluid, or wax-based oils in the air system. These fluids may cause severe damage to air system components. • Maintain the air compressor to prevent excessive oil bypass. • Replace worn seals in valves and air motors as they are needed. Your authorized dealer carries rebuild kits for most units.
AIR SYSTEM 5. Start the engine and build up the air pressure again. 6. Stop the engine, and apply the brakes fully. Apply the brake pedal and hold it down for five minutes. The pressure drop should not exceed 3.0 psi (21 kPa) per minute. 7. If you detect excessive leakage (air pressure loss greater than 3.0 psi (21 kPa) after five minutes of brake application), a leakage test should be made at the air line connections and at all air brake control units.
AIR SYSTEM presence of excessive carbon. If excessive carbon is found, clean or replace the compressor cylinder head. Also, check compressor discharge line for carbon, and clean or replace the discharge line if necessary. Preventive Maintenance The following service checks are provided for your information only and should be performed by a certified mechanic. Contact your dealer or the engine manufacturer's Maintenance Manual for further information on servicing air compressors.
BRAKE SYSTEM BRAKE SYSTEM Brake Adjustment WARNING! Do not work on the brake system without the parking brake set and wheels chocked securely. If the vehicle is not secured to prevent uncontrolled vehicle movement, it could roll and cause death, serious personal injury or damage to the vehicle. 5 To operate your vehicle safely and profitably, you need some understanding of its brake systems. For more on brakes, see the Index, under Brakes.
BRAKE SYSTEM Air Disc Brakes WARNING! WARNING! Do not use any replacement part in the brake system unless it conforms exactly to original specifications. A nonconforming part in your vehicle's brake system could cause a malfunction resulting in an accident causing death or personal injury. Sizes and types are so related to one another that a seemingly unimportant change in one may result in a change in how well the brakes work for you on the road.
BRAKE SYSTEM • Have a qualified mechanic perform a detailed inspection if the notches are not found. The pads and rotors should be measured and compared against the manufacturer's specifications located in the brake manufacturer’s service manual. • Chock the wheels. • Temporarily release the parking brakes. • Grab the caliper and move it. This movement is Running Clearance. • Proper Running Clearance is 0.
BRAKE SYSTEM Drum Brakes Automatic Slack Adjusters Have brake drum linings and disc brake pads inspected by a qualified mechanic for wear at regular intervals according to the maintenance schedule. In severe service or off-highway applications inspect the linings more frequently. Periodically check the Brake Chamber Stroke. Replace the slack adjuster if proper stroke cannot be maintained.
BRAKE SYSTEM WARNING! Manual adjustment of automatic slack adjusters is a dangerous practice that could have serious consequences. It gives the operator a false sense of security about the effectiveness of the brakes. Contact the Service Department at your dealership if the stroke exceeds the above specifications. A stroke exceeding these values may indicate a problem with the slack adjuster or the brake foundation.
CAB CAB Chrome and Aluminum Surfaces Exterior Maintenance To prevent rust, keep chromed parts clean and protected with wax at all times, especially in winter conditions where the roads are salted. Painted Surfaces Wash painted surfaces frequently to remove grime and caustic deposits which may stain the finish. See Cleaning, Protecting, and Weather Stripping on page 5-72. • If necessary, use a commercial chrome cleaner to remove light rust. • Chrome surfaces are best cleaned with fresh water.
CAB Tail Pipe Surface Cleaning WARNING! Always allow hot surfaces to cool down before attempting to work near them. Failure to comply may result in death or personal injury. 5 To maintain your quality finish, wash with a soft cloth, mild soap and water or glass cleaner. A non-abrasive chrome polish can be used sparingly on hard to clean areas. Do Not clean your high heat chrome using scouring pads, abrasive chrome polish, highly acidic chemical cleaners or any other abrasive cleaners.
CAB Vehicle Cleaning WARNING! Precautions Do not clean the underside of chassis, fenders wheel covers, etc. without protecting your hands and arms. You may cut yourself on sharp-edged metal parts. Failure to comply may result in death, personal injury, equipment or property damage. WARNING! Handle cleaning agents carefully. Cleaning agents may be poisonous. Keep them out of the reach of children. Failure to comply may result in death, personal injury, equipment or property damage.
CAB plated, and polished metal surfaces. Washing the Exterior CAUTION Do not aim the water jet directly at door locks or latch. Tape the key holes to prevent water from seeping into the lock cylinders. Water in lock cylinders should be removed with compressed air. To prevent locks from freezing in the winter, squirt glycerin or lock deicer into the lock cylinders. 1. ° ° 2. 5 5-74 Begin by spraying water over the dry surface to remove all loose dirt before applying the car wash and wax solution.
CAB Cleaning the Chassis NOTE To allow enough time for your truck's finish to cure, wait at least thirty days after the date of manufacture before waxing. • Do not apply wax in the hot sun. • Never dust off dry surfaces with a cloth because it will scratch the finishes. • • Hose dirt and grime from the entire chassis. Then, if an oil leak develops, you will be able to detect it easier. Corrosive materials used for ice and snow removal and dust control can collect on the underbody.
CAB Passenger Door Lower View Window There may be occasions when the inner view window must be removed for maintenance cleaning and/or damage. Follow this procedure when installing and removing an inner view window. The recommended tool for removal of the glass is a glass stick, although other tools may be used provided proper caution is observed. CAUTION 5 The use of screwdrivers, gasket tools, knives or other similar instruments may damage the seal or break the glass.
CAB Use the glass stick to leverage the glass out of the seal. Continue this process along the entire front edge of the seal until the glass is free.

TIRES AND WHEEL TIRES AND WHEEL Tires WARNING! 5 Regular, frequent inspection and the right care will give you the assurance of safe and reliable tire operation. Here are some tips on maintaining your tires. Do not repair damaged tires unless you are fully qualified and equipped to do so. Wheel and tire assemblies cannot be worked on without proper tools and equipment, such as: safety cages or restraining devices. Have all tire repairs performed by an expert.
TIRES AND WHEEL Underinflated Tires Low pressure is a tire’s worst enemy. Underinflation allows tires to flex improperly, causing high temperatures to build up. Heat causes early tire damage such as flex break, radial cracks, and ply separation. Low pressure may affect control of your vehicle, especially at the front wheels. Most tire wear problems are caused by underinflation as the result of slow leaks, so you’ll want to check tire pressure regularly.
TIRES AND WHEEL Overloaded Tires 1 3 Proper-Inflation: the correct profile for full contact with the road. TREAD CONTACT WITH ROAD TREAD CONTACT WITH ROAD Over-Inflation: reduces the tread contact area with the road surface, concentrating all of the vehicle weight on the center of the tread. This causes premature wear of the tire. Overloading your truck is as damaging to your tires as underinflation. The following chart shows how neglect or deliberate abuse can affect the life of your tires.
TIRES AND WHEEL Overinflated Tires Matching Tires Too much air pressure reduces the tire tread contact area and results in rapid wear in the center of the tread. Be sure to buy matched tires for your vehicle, especially on the rear axles. Mismatched tires can cause stress between axles and cause the temperature of your axle lubricant to get too hot. Matched tires will help your driveline last longer and will give you better tire mileage. WARNING! WARNING! Overinflated tires can cause accidents.
TIRES AND WHEEL Replacing Tires Greenhouse Gas Certified Tires WARNING! Front: Replace front tires when less than 4/32 in. of tread remains. Check at three places equally spaced around the tire. Drive Axles or Trailers: Replace tires on drive axles or trailers when less than 2/32 in. of tread depth remains in any major groove. Check at three places equally spaced around the tire. See the next illustration for recommended measuring points for tread depth.
TIRES AND WHEEL Speed Restricted Tires Tire Chains Maintaining a greenhouse gas certified tire. In order to limit the rolling resistance of the tires and optimize fuel economy, the maintenance procedures specified by the tire manufacture must be followed. For warranty information, See Original Equipment Tires on page 6-10. If you need tire chains, install them on both sides of each driving axle.
TIRES AND WHEEL Wheel Mounting and Fastening After the vehicle travels about 50 to 100 miles (80 to 160 km), wheel mountings seat in and will lose some initial torque. Check hub/wheel mountings after this initial period and retighten. Wheel Cap Nut Torque WARNING! Never use oil or grease on studs or nuts; improper torque readings will result, which could cause improper wheel clamping and could lead to a wheel failure resulting in an accident.

TIRES AND WHEEL Wheel Replacement with Disc Brake Option WARNING! Tighten wheel cap nuts properly. If they are not tightened properly, wheel nuts could eventually cause the wheel to become loose, to fail, and/or to come off while the vehicle is moving, possibly causing loss of control and may result in death, personal injury, equipment or property damage.
TIRES AND WHEEL with the disc brake assembly. When installing any replacement wheel, always inspect the tires/wheels to ensure there is adequate clearance between other vehicle components. With the hood open, check for clearance between the wheel and disc brake assembly. Use a hydraulic jack to raise the front of the vehicle off the ground to allow the wheel to spin freely. While rotating the wheel, check to ensure there is adequate clearance between the wheel and disc brake assembly.
TIRES AND WHEEL Disc Wheels WARNING! Use the correct components and tools when working on wheels. Grooves in the wheel disc or other damage to the disc can weaken the wheel and cause it to eventually come off. This could cause you to lose control of your vehicle, and may result in an accident. Failure to comply may result in death, personal injury, equipment or property damage. 5 The end of the wheel wrench must be smooth. Burrs on the end of the wrench can tear grooves in the disc.
WHEEL BEARING WHEEL BEARING Wheel Bearing Adjustment For safe, reliable operation and adequate service life, your wheel bearings must be adjusted properly at the recommended intervals. Contact your authorized dealer to make sure the wheel bearings are properly adjusted.
TRANSMISSION MAINTENANCE TRANSMISSION MAINTENANCE Introduction Proper maintenance of the transmission will ensure that the vehicle will operate efficiently. 5 To check the transmission fluid level, park the vehicle on level ground. For an automatic transmission the oil level should be checked with the engine idling and the transmission fluid at operating temperature. Checking the fluid of a manual transmission may be done with the engine off.
TRANSMISSION MAINTENANCE Transmission Lubricants Service Intervals Standard Transmission Oil Level Manual Transmission Manual transmissions are designed so that the internal parts operate in a bath of oil circulated by the motion of gears and shafts. For recommended types and brands of all lubricants, see the transmission manufacturer's Service Manual and Preventive Maintenance Schedule on page 5-12. Check all hoses for kinks, deterioration, chafing, and leaks.
TRANSMISSION MAINTENANCE Automatic Transmissions Automatic Transmission Oil Level Service Intervals NOTE Check daily with engine idling. See Preventive Maintenance Schedule on page 5-12 for service intervals. The vehicle must be parked on level ground. See the Transmission Operator's Manual for information on checking the transmission oil level.
CLUTCH CLUTCH Introduction Free pedal is the distance the clutch pedal moves by applying only slight pressure. During free pedal the release yoke in the transmission moves until its bearing pads contact the release bearing. This movement of the release yoke is called free travel. Thus, free pedal and free travel are directly related to each other. As the clutch pedal is depressed further, with harder pressure, the release yoke moves the release bearing away from the engine.
CLUTCH Clutch Linkage This vehicle is equipped with a rod and lever mechanical clutch linkage. Lubricate each pivot point on the clutch linkage.
