`
`4. GENERAL DESCRIPTION (Figs. 1 and 2)
`
`a. Vehicle described in this manual is known as Truck, Amphibi-
`
`an, 6x6, DUKW-353, and is designed for amphibious service—opera-
`
`tion on land or water. Vehicle has automotive characteristics of a
`
`6x6 conventional truck, and in addition is equipped with an integral
`
`water-tight hull designed in such a manner that truck chassis and
`
`drive units are attached to and in body of hull. For land operation,
`
`vehicle utilizes six driving wheels driven by conventional six cylinder
`
`valve-in-head engine through transmission, transfer case, and pro-
`
`peller shafts. For water operation, vehicle is propelled with a water
`
`propeller powered from engine through transmission and a water
`
`propeller transfer case. As a truck, front wheels are steered with
`
`conventional steering gear assembly. When operating in water, ve-
`
`hicle is steered with combined use of front wheels and a rudder which
`
`is interconnected to and operated by the steering gear column.
`
`5. IDENTIFICATION
`
`a. Vehicle may be identified by six driving wheels, "boat" shaped
`
`body or hull, and low silhouette cab and cargo compartment. Springs
`
`and driving axles are attached to bottom of hull and suspend in water
`
`when in use as a boat. Water propeller and rudder are mounted in
`
`tunnel at rear.
`
`b. Identification Plates
`
`(1) Vehicle serial number plates. Vehicle serial number plate,
`
`Fig. 3, includes vehicle nomenclature, model, pay load, etc., as shown
`
`in illustrations.
`
`(2) Publication plates. Publication plate, Fig. 4, gives the TM
`
`number of the technical manual and parts list to use with these ve-
`
`hicles.
`
`(3) Engine serial number. Engine serial number plate, Fig. 5,
`
`is mounted on left-hand side of engine lower part of cylinder block
`
`and includes information as shown in illustrations.

`8. DRIVER'S GENERAL INSTRUCTIONS
`
`a. General. Information and instructions outlined in this sec-
`
`tion embrace not only the essential factors of driving this vehicle on
`
`land as a conventional truck, but also include unique and important
`
`instructions for operation of vehicle in amphibious service. Opera-
`
`tion of an amphibious vehicle of this type requires basic training in
`
`truck driving, together with a knowledge of water operation funda-
`
`mentals.
`
`b. Land Operation. Driving the vehicle as a "land" truck re-
`
`quires the knowledge of all the fundamentals of operating a conven-
`
`tional 6x6 truck. In addition, the driver must take into considera-
`
`tion certain characteristics of this vehicle. In addition, driver should
`
`consider special characteristics of the vehicle such as width, height,
`
`length, front and rear overhangs, visibility and weight.
`
`c. Water Operation. Experience as a driver of a 6 x 6 truck is
`
`the basis of amphibious service training; however, operating per-
`
`sonnel should be familiar with instructions applicable to water oper-
`
`ation before attempting to operate the vehicle in water.

`CONTROLS AND OPERATION
`
`9. TROUBLE-SHOOTING
`
`a. Trouble-shooting tables included in other sections of this
`
`manual should be thoroughly studied by driver and crew. These
`
`tables will enable the crew to recognize even gradual changes in the
`
`mechanical condition of various units, and will thus encourage cor-
`
`rective service before failure. Knowledge of various trouble symp-
`
`toms, causes, and remedies will enable driver and crew to apply
`
`emergency measures when operating under critical and adverse con-
`
`ditions.
`
`10. VEHICLE NOMENCLATURE AND TERMS
`
`a. There are many parts of an amphibious truck which are dif-
`
`ferent than those generally encountered on a "land" truck. In addi-
`
`tion, terms are employed in the operation of vehicle in water which
`
`are not generally used when operating vehicle as a truck. Wherever
`
`possible, use of marine terms when describing various component
`
`parts of vehicle have been avoided. However, in some instances,
`
`nomenclature generally applied to a boat must necessarily be used,
`
`particularly when describing water propeller, bilges, rudder, etc.
`
`Reference should be made to Fig. 8.
`
`c. Definition of Terms. Following table defines various operat-
`
`ing terms and nomenclature used in describing vehicle and its opera-
`
`tion throughout this manual.

`
`11. OIL, GAS, AND WATER SUPPLY
`
`a. Crankcase Oil
`
`(1) Crankcase oil filler neck (Fig. 9), mounted on right-hand
`
`side of engine, is accessible after engine compartment hatch is
`
`raised. Lubricant capacity of crankcase, type of lubricant recom-
`
`mended, and filling, draining, and flushing intervals are outlined in
`
`Section VI, "Lubrication."
`
`(2) Oil filler dip stick (Fig. 9), mounted on right-hand side of
`
`engine, is also accessible after engine compartment hatch is raised.
`
`Lower portion of dip stick is graduated showing relative oil level of
`
`crankcase. Dip stick should be pulled out, lower portion wiped off
`
`with a clean cloth, reinserted to its limit, then pulled out again for
`
`correct reading. Oil level of crankcase will be indicated on graduated
`
`portion of gauge or dip stick. Crankcase oil should be kept up to the
`
`"full" mark.

`
`b. Fuel Supply
`
`(1) Octane rating. For best performance, gasoline with an
`
`octane rating of 70 or above should be used. Instruction plate is
`
`placed on engine valve cover. Fuel with an octane rating with less
`
`than that recommended necessitates the readjustment of ignition
`
`timing and, as a general rule, engine performance will be affected.
`
`(2) Fuel tank filler neck is located at rear of vehicle on left-hand
`
`side. CAUTION: When replenishing fuel tank, same precaution
`
`should be taken as when filling fuel tank on a conventional truck.
`
`Supply filler hose should be properly grounded to prevent static
`
`sparks and care should be taken to prevent entrance of dirt or water
`
`into fuel tank.
`
`(3) Important: If any fuel has been spilled into compartments
`
`of hull, these compartments must be thoroughly cleaned and all
`
`fumes evacuated before attempting to start engine. As a matter of
`
`precaution, engine compartment hatch should be raised and compart-
`
`ment ventilated before and after engine operation.
`
`c. Cooling System Supply
`
`(1) The basis of coolant for engine cooling system is fresh, clean
`
`water to which should be added inhibitors (rust preventives) and
`
`anti-freeze solutions (at temperature below 32°F.). Do not use salt
`
`water in cooling system except in extreme emergency — then drain
`
`and flush when fresh water is available.
`
`(2) Radiator filler cap is accessible after engine compartment
`
`hatch has been raised. This cap is conventional notch type and care
`
`should be taken when removing it if engine is hot.
`
`(3) If engine overheats from lack of water, do not add cold water
`
`immediately. Radiator should only be filled after boiling has ceased
`
`and engine cooled down, then add water slowly, preferably with en-
`
`gine running. Cold water should not be poured into system when
`
`engine is hot as such change in temperature may damage cylinder
`
`head and block.
`
`12. INSTRUMENTS, SWITCHES, AND GAUGES
`
`a. Operating instruments, switches, and gauges are, with few
`
`exceptions as noted, mounted on instrument panel (Figs. 10 and 11),
`
`located directly in front of driver. Location and purpose of these con-
`
`trols are outlined in succeeding paragraphs.
`
`b. Temperature Gauge. This gauge indicates temperature of
`
`water in cooling system (not quantity of water in system). Water

`
`temperature depends upon operating conditions, load, etc. Normal
`
`operating temperature range should be between 160°F. to 185°F.
`
`If temperature should reach 212°F. (generally boiling), engine
`
`should be stopped and cause of overheating determined and cor-

`
`recled. This is not an electrically operated instrument and will indi-
`
`cate temperature of the cooling system at all times from 100°F. to
`
`220°F.
`
`c. Fuel Gauge. Fuel gauge, electrically operated, indicates level
`
`of gasoline in fuel tank and is only operative when ignition switch
`
`is turned on.
`
`d. Speedometer. Speedometer indicates road speed of vehicle
`
`in miles per hour. The instrument records total number of miles
`
`operated and "trip" miles. "Trip" indicator can be cleared by turning
`
`knurled button located on under side of speedometer head. Do not
`
`allow vehicle road speed to exceed maximum permissible speeds
`
`shown on plate, Fig. 7. This instrument will not indicate miles per
`
`hour operation in water, nor total miles operated in water.
`
`e. Oil Pressure Gauge. Oil pressure gauge on instrument panel
`
`indicates pressure of engine lubrication oil. Pressure reading may
`
`vary according to operating conditions. However, if oil pressure
`
`should fall to zero while engine is running, stop engine immediately
`
`and determine cause. This gauge does not indicate amount of oil in
`
`crankcase.
`
`f. Ammeter on instrument panel indicates rate of electric current
`
`flow being applied to battery by generator, or rate of discharge from
`
`battery. At low engine speeds, needle may show a negative or dis-
`
`charge reading.
`
`g. Ignition Switch. Ignition switch is lever type and handle
`
`must be turned "on" before engine can be started. Do not allow
`
`switch to remain turned "on" with engine not running except when
`
`making necessary tests.
`
`h. Choke Button. Choke button (marked "choke") should only
`
`be pulled out far enough to allow engine to run smoothly during
`
`warm-up period and should be allowed to return to "open" position
`
`as soon as possible after engine is started. Return spring on choke
`
`linkage returns choke valve to open position when control button is
`
`released.
`
`i. Throttle Button. Throttle button (marked "throttle") on in-
`
`strument panel may be used for starting engine or to set throttle at
`
`a sustained speed. Button can be pulled out in varying degrees, ac-
`
`celerating engine from idling speed to maximum governed speed.
`
`j. Main Light Switch. Main light switch (Fig. 12), located on
`
`instrument pan
