Book 8 In the diesel engine, there is continuous combustion during the entire length of the power stroke, and pressure resulting from combustion remains approximately constant throughout the stroke. Because of these facts, the cycle of the gasoline engine is often referred to as having constant-______ combustion while the diesel cycle is said to have constant-______ combustion.
volume pressure
Book 8 The following limitations must be overcome when a gasoline or diesel engine is used to power apparatus: The engine must be rotating to develop horsepower. It rotates in one direction only. It must be operated within the limits of the effective torque range.
reference
Book 8 The drive train components (also referred to as the power train) allow apparatus to be utilized in a number of capacities. Such as driving, pumping, and aerial ladder operations. The purpose of the power train is to transmit the power of the engine to the drive wheels.
reference
Book 8 The flywheel stores up energy of rotation when the instantaneous torque on the crankshaft is greater than average, and releases this energy when the torque is less than average.
reference
Book 8 By means of the clutch, the operator can harness the power of the engine, by connecting or disconnecting the engine from the power train. This is essential for starting the engine, allowing the vehicle to stand motionless while the engine is running, gradual engagement of the engine to the power train, and for allowing gear ratios to be changed to meet varying road conditions. It is very important that the clutch is not allowed to slip for more than about 1-1/2 seconds.
reference
Book 8 The purpose of the clutch brake is to stop the rotation of the gears in the road transmission. REMEMBER ! THE CLUTCH BRAKE IS DESIGNED-TO STOP THE GEARS IN THE TRANSMISSION WHEN THE CLUTCH PEDAL IS FULLY DEPRESSED.

Book 8 Heavy Apparatus: (____ cubic inches or over) shall be lubricated and receive an oil change at 2,000 miles or four months, whichever occurs first. The oil filter shall be changed every 12 months. volume 3 says oil change 4,000 miles
465 cubic inches
Book 8 Engine Tune-up, every-12,000 miles. 2. Transmission maintenance, every 20,000 miles. Appointments should be made approximately ___ miles before the actual mileage is recorded on the odometer.
500
Book 8 Transmission fluid check 1. If it felt cool (about room temperature) the level should be (1/8 to 3/8”) below the “ADD” mark. The dipstick has two dimples below the “ADD” mark to show this range. 2. If it felt warm, the level should be close to the “ADD” mark ‘(either above or below). 3. If it was too hot to hold, the level should be at the “FULL” mark. Add just enough DEXTRON II fluid to fill the transmission to the proper level. It takes only one pint to raise the level from *ADD” to “FULL” with a hot transmission.
reference
Book 8 The automatic transmission is connected to the engine by a fluid coupling or torque converter instead of a clutch assembly. It is important that the operator of heavy apparatus with an automatic transmission properly control the apparatus by using proper shifting techniques.
reference
Book 8 The torque converter serves two primary functions. First, it acts as a fluid coupling to smoothly connect engine power through oil to the transmission gear train. Second, it multiplies the torque, or twisting effort, from the engine when additional performance is desired.
reference
Book 8 Transmission Torque Converter The converter consists of 3 elements: Pump, stator and turbine. The converter provides maximum torque when load conditions demand. oil for converter charging pressure comes from the sump and is supplied by the transmission oil pump.
reference
Book 8 Transmission Lockup Clutch The lockup clutch consists of a single clutch plate, back plate and piston located between the converter turbine assembly and the transmission flywheel assembly (or converter drive housing), The lockup clutch plate is splined to the hub of the converter turbine assembly. Then the lockup clutch is applied, the turbine and the converter pump are locked together and rotate as a unit. Engine output is then directed to the transmission gearing at a speed ratio of 1:1; bypassing the torque converter. Lockup occurs in all forward gears, but not in reverse or neutral.
reference
Book 8 Transmission Planetary Gearing The planetary gear train is made up of four (4) constant mesh, straight spur gear planetary sets. The forward set is arranged for direct drive and is called the splitter planetary. The three rear sets are intermediate- low-, and reverse-range planetaries. By the engagement of the clutches in various combinations, the planetary sets act singly or together to provide four (4) forward speeds and one (1) reverse.
reference
Book 8 Transmission Clutches The clutches direct the flow of torque through transmission in accordance with gear selected. All clutches are hydraulically applied, spring released, and oil cooled. The friction surfaces are sintered bronze against steel. Any wear is automatically compensated. Thus, no adjustment is ever necessary except when rebuilding the transmission.
reference
Book 8 Transmission Hydraulic System A single, pressurized hydraulic system serves the converter and transmission. Oil for the hydraulic operations, lubrication and cooling comes from the sump and is supplied by the same pump. Although your ALLISON Transmission is rugged in design, certain precautions and procedures must be follows to insure long, trouble-free service.

Book 8 Transmission Towing or Pushing NOTE: THE ENGINE CANNOT BE STARTED BY TOWING OR PUSHING. BEFORE TOWING OR PUSHING BEYOND A FEW BLOCKS, THE DRIVELINE MUST BE DISCONNECTED.
reference
Book 8 Universal Joints A universal joint is a flexible coupling between two shafts that permits one shaft to drive another at an angle to it. This unit is necessary to provide flexibility in the power train as the vehicle travels over uneven surfaces
reference
Book 8 Slip Joints As the vehicle travels over uneven ground, the distance between the transmission and the rear-end varies.
reference
Book 8 Propeller Shaft Also known as Drive shaft, or Drive line. This device carries the torque from the transmission to the rear-end.
reference
Book 8 Final Drive Its function is to change the direction of the power that is transmitted by the propeller shaft through 90 degrees to the driving axles. A common final drive ratio for L.A.F.D. apparatus is, 4.11 to 1, That is approximately four revolutions of the propeller shaft to one revolution of the rearwheels
reference
Book 8 Differential The differential is the unit that allows the axles to turn at different speeds from each other while still pulling the apparatus.
reference
Book 8 Live Axles A live axle is one that supports part of the weight of the vehicle and also drives the wheels connected to it. The term “live axle” is opposed to the term “dead axle”. A dead axle is one that carries part of the weight of the vehicle but does not drive the wheels.
reference
Book 8 Heavy apparatus, ambulances, and pick-up trucks (rated above 3/4 ton), generally have Full floating drive axles. This type of live axle assembly is for heavy duty use. The wheels are not attached directly to the end of the axles, but are attached to a hub. The hub rides on the axle housing through wheel bearings. The stress caused by turning, skidding, and shock are applied directly to the axle housing, which is designed to carry heavy loads.
reference
Book 8 In traffic stay in the highest gear that allows the apparatus to keep up with traffic and still have some power in reserve for acceleration. When cruising choose a gear that will cruise the engine at ____ to ____ RPM lower than the ninety percent speed. This reduces engine wear, power losses caused by the fan drive-line, and accessories, noise, and fuel consumption.
200 to 300
Book 8 Although the transmissions used by the LAFD are true automatic transmissions they will give much better performance!!!, smoother operation!!!, and more longevity!!! if they are operated as if they were a “clutchless” manual shift transmission. Automatic transmission used by the LAFD are adjusted for optimum full throttle shifts. The light throttle shifts may seem to be harsh or slightly severe.
reference
Book 8 Under no circumstances allow your apparatus to coast in neutral. When coasting in neutral or being towed with the drive shaft connected, the rear wheels become the driving force, therefore causing the planetary gears in the transmission to overdrive. In addition, coasting in neutral does not allow the engine to help slow the apparatus. (This is an illegal operation.)
reference
Book 8 Improper downhill driving can be-devastating to engine parts. When descending, the driver will often downshift to control speed and to avoid excessive use of the brakes. What actually happens is that the load is pushing the vehicle downhill and the governor cannot control engine speed. The wheels are turning the driveshaft and the engine. Drivers should select a lower gear when descending, remain in that gear at all times and use a combination of brakes and gears to prevent over-speeding the engine.
