Proper operation and maintenance are key factors in determining the useful life and operating economy of a diesel engine. Follow these directions for trouble-free, economical operation.  

Proper operation and maintenance are key factors in determining the useful life and operating economy of a diesel engine. Follow these directions for trouble-free, economical operation.  

To Start Engine Detroit Diesel Engines will start at temperatures above 0 degrees F ( - 12 degrees C) without using a starting aid. However, for colder temperatures it may be necessary to activate the engine block heater (120 volt ac-operated) to heat the crankcase oil. The ENGINE BLOCK HEATER is controlled by the battery heater breaker. Remember to set the breaker OFF when the heater is no longer needed.

==== Remote Engine Starting ====

====Remote Engine Starting====

Because it may sometimes be necessary to start the diesel engine remotely, a separate key switch is located on the right side of the engine compartment. This ignition switch has no accessory position; only OFF-ON and START positions can be used. Be sure the hinged switch cover is snapped back in place after key withdrawal to prevent moisture damage. Toggle switch must be down (REAR) to start from engine compartment.

Either of the above actions will result in transmission retarder braking action and illuminate the blue indicator light at the dash OFF/ON switch.  

'''Cautions:''' Apply and operate the retarder with engine at closed throttle only. Do Not use the retarder when road surfaces are slippery. Do not apply retarder control or de-energize the system at the master control switch. Observe transmission and engine temperature limits at· all times. Select the lowest possible transmission range to increase the cooling system capacity and total retardation available. In the event of overheating, decrease vehicle speed to reduce retardation power requirements . Observe the retarder "ALERT LIGHT" to ensure that the vehicle control system is functioning properly.

==== 8V92Engine ====

====8V92Engine====

The Detroit Diesel Allison transmission (8V92 engine) provides four forward ranges and one in reverse. Speed selection is provided through the transmission shift panel. The selector must be in N (neutral) position when the engine is started . If the engine can start in any other position , the neutral start switch deficiency should be corrected as soon as possible. Use D position for all normal driving conditions so that the coach begins moving in first gear and upshifts automatically into 2nd, 3rd , and 4th gears. As the coach slows , the transmission automatically downshifts to the correct gear. Use a low gear 2 or 3 when road, load or traffic conditions make it desirable to restrict automatic shifting to a lower range; or use the Allison transmission retarder , as .J previously described . Use 1 or 2 when pulling through mud and snow or driving up steep grades (See table 8-3 for gradeability) . The vehicle should be completely stopped before shifting into reverse.

==== Driving Tips ====

====Driving Tips====

'''Accelerator Control''' Foot pressure on the accelerator pedal influences the automatic upshifting or downshifting within each driving range . When the pedal is fully depressed against the floor pedal stop , the transmission automatically upshifts near the recommended governed speed of the engine . A partially depressed position of the pedal causes the upshifts to occur sooner at a lower engine speed. This throttle-modulation method provides the accurate shift spacing and control necessary for maximum performance.

A partially depressed position of the pedal causes the upshifts to occur sooner at a lower engine speed. This throttle-modulation method provides the accurate shift spacing and control necessary for maximum performance.

'''Transmission Oil Temperature''' Extended operation at low vehicle speeds, with the engine at full throttle , can cause excessively high temperature in the transmission . These temperatures may tend to overheat the engine cooling system as well as cause possible damage to the transmission. If excessive temperature is indicated by the engine coolant temperature gauge, stop the vehicle and determine the cause. If the cooling system appears to be functioning properly, the transmission is probably overheated. Shift to N and accelerate the engine to 1,200 to 1,500 RPM . This should reduce the oil sump temperature to operating level within a short time. If high temperatures persist , stop the engine and have the overheating condition investigated by service personnel.

'''Caution''' Do not operate the engine for more than 30 seconds at full throttle with the transmission in gear and the unit stationary. Prolonged operation of this type will cause the transmission oil temperature to become excessively high and may result in severe overheat damage to transmission components . Do not leave transmission in drive for more than 5 minutes while stationary because of heat damage.
