5040388 EVINRUDE * ROPE ANCHOR PLATE

These Caterpillar Electronic Truck Engines are:* direct injected* mechanically actuated electronic unit injected* turbocharged* air-to-air aftercooled (ATAAC)The electronic engine control system provides:* electronic governing* automatic air/fuel ratio control* torque rise shaping* injection timing control* system diagnosticsFunctions included in the electronic control are programmable features of:* cruise control* PTO governing* vehicle speed limiting* high gears rpm limiting* low gears rpm limiting* top engine limiting* idle shutdown timer* retarder controlAdditional benefits which provide engine fuel economy, serviceability, and driver comfort include:* improved cold starting capability* tamper resistance* diagnostics* progressive shift engine speed control* American Trucking Association (ATA) data link (SAE J1587)* an optional Engine Monitoring PackageAn electronic governor controls the unit injection pump output to maintain desired engine rpm. The governor functions include programmable low idle and 20 to 200 rpm governor overrun.Electronically controlled, mechanically actuated unit injectors, combined with the pumping, electronic fuel metering (duration and timing) and injecting elements, produce very high injection pressures. These unit injectors have full authority over engine fuel delivery to accurately control smoke limiting, white smoke and engine acceleration rates.Individual unit injection pumps, one for each cylinder, meter and pump fuel under high pressure. High injection pressures help to reduce fuel consumption and emissions. The use of this type of unit fuel injector provides total electronic control of injection timing. The injection timing varies with engine operating conditions. This optimizes the engine's performance for starting, emissions, noise, fuel consumption and driveability.Timing advance is achieved by precise control of injector firing. Engine speed is controlled by adjusting the firing duration. A speed timing sensor provides information to the Electronic Control Module (ECM) for detection of cylinder position and engine speed.The engines have built-in diagnostics to assure that all components are functioning and operating properly. In the event of a system component deviation from programmed limits, the operator will be alerted to the condition by a dashboard mounted CHECK ENGINE/DIAGNOSTIC lamp. A Caterpillar service tool or cruise control switches (if equipped) may be used to read the numerical code of the diagnostic flash code. There are three types of diagnostic codes:* ACTIVE (fault)* LOGGED* EVENTThese codes are logged and stored in the system memory. Refer to Engine Diagnostics section of this publication for additional information.The cooling system consists of:* a gear driven centrifugal pump* a temperature regulator* an oil cooler* an OEM radiator incorporating a shunt systemThe engine lubricating oil, supplied by a gear-type pump, is both cooled and filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine parts:* when oil viscosity is high* if either the oil cooler or the oil filter elements (paper cartridge) become pluggedEngine efficiency, efficiency of emission controls, and engine performance depend on adherence to proper operation and maintenance recommendations, and the use of recommended fuels, coolants and lubrication oils.Multi-Torque Rating (If Equipped)
Multi-torque ratings provide for additional torque as engine load increases. This feature provides higher torque levels and better driveability while in the top gears ONLY. The engine electronics are able to determine when the vehicle is in the top gears by calculating the engine rpm/vehicle speed ratio.The benefits of Multi-Torque are:* driver feel* less shifting in rolling terrain* less wear on drive line components* more responsive-better engine performanceWelding and Caterpillar Electronic Engines
Because the strength of the frame may decrease, some manufacturers do not recommended welding onto a truck frame or rail. Refer to your OEM regarding welding on a truck frame or rail.
Before welding on a vehicle equipped with an electronic engine, the precautions that follow should be observed:* Disconnect all cables connected to the vehicle batteries* Disconnect both ECM Connectors (J1/P1 and J2/P2)* Do not use the ECM or Engine Ground Stud for grounding of the welder* Locate the ground as close as possible to the welding area
