International LT and RH Overview and Walk-around Study Guide 6 Module 1: Engine and Drivetrain FOR TRAINING PURPOSES, THIS COURSE WILL FOCUS ON THE INTERNATIONAL LT. THE INFORMATION IN THIS COURSE ALSO APPLIES TO THE INTERNATIONAL RH. The International LT is offered with a choice of two engines, the Cummins X15 and the International A26. A26 and X15 Overview The International A26 is a 12.4 liter diesel engine equipped with emissions controls that vary depending on the year of emissions certification. Oil Filter Module On the A26, the oil filter is engine mounted and located near the right front corner of the engine. The oil filter element is a cartridge style filter, and can be replaced separately from the filter cap and housing. The 2017 A26 engine offers a high volume primer pump, which reduces the time and effort needed to prime the fuel system. The Cummins X15 is a 15 liter diesel engine with similar emissions controls as the A26. As with the A26, the emissions controls on the X15 may vary with each emissions certification year. Emissions Label The emissions label on the X15 is located on the left front corner of the valve cover and has similar information to the A26's emissions label.
7 International LT and RH Overview and Walk-Around Study Guide Oil Filter A spin-on type oil filter is mounted on the right side of the engine, just below the turbocharger. When it is replaced, the entire filter is removed from the oil filter housing, discarded, and replaced with a new filter. Dipstick Location The engine oil dipstick has a yellow handle and is located near the left rear side of the engine. Oil Fill Location The engine oil fill tube is located on the left front side of the engine. In some applications, the tube is positioned so that the oil can be filled without the need for a funnel. Fuel Primer Pump The Cummins X15 uses an electric fuel primer pump, located just above the secondary fuel filter on the left side of the engine. Cooling System Surge Tank A transparent surge tank prevents over or under filling and allows for quick and accurate coolant level inspections. The surge tank collects air bubbles in the coolant to promote longer life of the water pump, cylinder liners, and Exhaust Gas Recirculation, or EGR, cooler. The surge tank is fitted with a 15 PSI rated cap. Coolant Temperature Management The International LT offers superior coolant temperature management, maintaining coolant temperature in an ideal range. This enables the use of a smaller cooling package, and a single radiator.
International LT and RH Overview and Walk-around Study Guide 8 Clutches Hydraulic A hydraulic clutch actuation system is standard on the International LT. With this system, the clutch is engaged and disengaged by using a hydraulic master cylinder connected to the clutch pedal to force pressurized fluid through a high pressure hose to a hydraulic slave cylinder. Benefits include longer clutch life, less shock to the vehicle s driveline and cargo, and a quieter cab environment. A translucent reservoir allows fluid level inspections at a glance and the system uses commonly available Department of Transportation, or DOT, type 3 or 4 brake fluid. Air Assisted Hydraulic An optional compressed air assisted hydraulic clutch actuation system is also available. This feature significantly reduces the force needed to actuate the clutch pedal. Grease Fittings Some LT vehicles may be equipped with an optional remote grease fitting that is used to lubricate the Clutch Release Bearing.

Driver Assist Systems
International LT and RH Overview and Walk-around Study Guide 14 ACC and CMS Introduction Module 4: Driver Assist Systems Bendix and WABCO both offer Adaptive Cruise Control (ACC) and a Collision Mitigation System (CMS) for use on the International LT. These Driver Assist systems should be used in addition to safe and alert driving practices. Bendix Wingman Advanced The standard Driver Assist system is the Bendix Wingman Advanced. This system allows the vehicle to adjust cruise control speeds to maintain a safe following distance behind vehicles ahead of the equipped vehicle. This system also has the ability to detect if a collision is likely, and warn the driver. Under most conditions, the system can slow the vehicle to avoid or reduce the chance of a collision. Omit Option The LT can be ordered without a Collision Mitigation System if the customer selects the Omit option when ordering the vehicle. Bendix Wingman Fusion The Bendix Wingman Fusion system is an optional system that improves on the Bendix Wingman Advanced system. When equipped, the vehicle gains Lane Departure Warning and Vehicle Overspeed Alerts and Action. Lane Departure Warning uses audible tones to alert the driver if the vehicle starts to leave its lane without the turn signal engaged. Overspeed Alerts notify the driver when the vehicle is traveling above the posted speed limit, and can even attempt to briefly slow the vehicle as an alert that the vehicle is traveling over the speed limit.
15 International LT and RH Overview and Walk-Around Study Guide WABCO OnGuard ACTIVE The WABCO OnGuard ACTIVE system detects vehicles in the path of travel and adjusts vehicle speed as needed to maintain following distance and reduce the chance of collisions. Visual and Physical feedback, such as flashing lights and vibrating seats, are used to alert the driver when driver intervention is needed. Bendix Blindspotter The International LT also offers optional side object detection. If equipped, the vehicle can alert the driver when vehicles may be in their passenger side blind spot. Bendix AutoVue 3G Bendix AutoVue 3G is an optional lane departure system that uses a windshield mounted camera to track visible lane markings day or night, and in most weather conditions. When the AutoVue 3G system detects drifting across lane markers without a turn signal being activated, it sounds an alarm to alert the driver to take corrective action. WABCO OnLane Wabco OnLane is an optional Lane Departure System that warns when unintentional lane drifting is detected. A camera is used to monitor and calculate the vehicle s position in the lane. OnLane delivers an audible alarm when crossing lane markings without the turn signal being activated. This can alert the driver to take corrective action preventing potential collisions or run-off-road accidents. Some applications offer video capture when critical events are detected.
International LT and RH Overview and Walk-around Study Guide 16 Vehicle Exterior Introduction Module 4: Vehicle Exterior The exterior of the International LT has been designed with multiple visual and functional features, focusing on fuel efficiency and driver comfort.
