    3500 SERIES ENGINES LESV0508INTRODUCTION, SYSTEM, & MAINTENANCE

    LEVELS I and IIThis presentation is an introduction to the 3500 Series Engine. This training materialteaches outside components and systems flow of the 3500 Series Engine. In addition, itgives information and procedures for preventive maintenance at normal service intervals.

    The 3500 Series has different arrangements for different applications (VEHICULAR,INDUSTRIAL, MARINE, MARINE AUXILIARY, AND GENERATOR SET).

    PREREQUISITESThe serviceman must have completed a Basic Diesel Engine Course (or similar training)including diesel engine construction and operation, engine system components andsystems operation. The serviceman must have done work on diesel engines such asadjusting, repairing and servicing.

    OBJECTIVESAfter learning the information in this Meeting Guide, the serviceman can:

    1. find basic components on the engine2. tell the function of engine components3. find system components and follow (trace) flow through:

    a. the air induction and exhaust systemb. the cooling system,c. the lubrication system; andd. the fuel system; and

    4. tell the procedures given for adjustment, maintenance and service of the engine.

    NOTE: This presentation give Level II knowledge of the 3500 Series Engine. Theinstructor can give skill training after this presentation. Skill training will give eachserviceman the ability to do the different jobs that are needed to service the 3500 SeriesEngine.

    REFERENCESThe following material will be use for instructor and serviceman references:

    1. Service Manual SEBR05482. Parts Book SEBP1292

    3. Operation and Maintenance Guide SEBV58544. Engine Literature SEBD0506-01

    Engine Literature is a list of different service information material which is available. Thislist is used by the instructor to find materials which can be used to teach servicemen to dothe different jobs expected of them.

    DIRECTIONS TO THE INSTRUCTORWhen you get ready to teach this STMG, do as follows:

    1. Read all of the information (script) for each slide in the presentation.2. Read the recommendation for FOLLOW-UP training.3. Show (project) the slide. Make sure you know exactly what points are to be

    seen on each slide and to be learned by the serviceman.4. Read the script again and add any notes that you will need to teach the presentation.5. Read service literature (references) as necessary.6. Look at a 3500 Series Engine and learn what you need to teach.7. ORDER copies of references for use by servicemen.8. Make a plan for FOLLOW-UP training.

    INTRODUCTION

    This presentation is about the 3500 Series Engine. Onearrangement of the 3516 Vehicular Engine is usedfor most illustrations.

    The 3500 Series Engine is a diesel engine with a4-stroke cycle. It has a 60 degree Vee angle

    between the cylinders of the block. The cylinderbore is 170 mm (6.7 inch) and the piston stroke is190 mm (7.5 inch). Each cylinder hasapproximately 4310 cu. cm. (263 cu. in.).Standard engine rotation is counterclockwise. Seethe Service Manual for Firing under specs (V8and V16).

    ORIENTATION

    Looking at the right side of the engine, we see the:

    1. cylinder heads, block and oil pan2. valve covers3. rear lifting eye4. turbocharger (one of two)5. oil cooler and oil pump6. fuel priming pump, two secondary fuel filters,

    and fuel transfer pump7. crankcase filler opening and dipstick8. air starting motor9. water pump; and

    10. alternator

    NOTE: This is the first Caterpillar engine designed tometric dimensions. All engines in the series have thesame bore and stroke and have the push rod valvedesign. All engines are turbo charged andaftercooled. All 3500 Series Engines have directinjection combustion systems with a unit injectorfuel system.

    WARNING !

    When you lift the engine, use a spreader bar(FT953). Keep the front and rear chains vertical. Seethe Service Manual for weight specs.

    On the front of the engine, we see:

    1. the Caterpillar 3161 governor 2. the water pump and the line to the aftercooler3. the thermostat housing and the bypass line4. the vibration damper, and crankshaft pulley

    The fan pulley and idler pulley is driven from thecrankshaft pulley belts. The fan pulley and idlerpulley each have an adjustment to adjust thetension of the fan (drive) belts.

    The plates shown on the right can be removed to installother accessories on the auxiliary drives. Thegovernor and crankcase breather can be installedon either the left side or right side.

  • On the left side we see:

    1. the oil supply line (arrow)2. the oil filter base/housing and four oil filters3. the oil supply and oil drain for the turbocharger 4. the fume disposal group

    Also on the rear we see three auxiliary drives above theflywheel housing. Two turbochargers areinstalled on this engine. This is the location ofthe turbochargers on the vehicle arrangements.Turbochargers can also be installed above therear of the engine for industrial generator set andmarine engines (shown later).

    On later engines, the plate is on the left-hand side infront of the cylinder head. This plate has thehigh idle rpm, full load rpm, power setting andother important engine information.

    Other plates and transfers (not shown) give youinformation about valve adjustment.

  • CRANKCASE EXPLOSION RELIEF VALVES

    Crankcase explosion relief valves, seen here, arenormally attachments but are required on marineengines. They are available for industrial andgenerator set arrangements. These valves relievethe pressure of an explosion in the crankcase. Anexplosion is possible when combustible gasesstart to burn because of heat or sparks. Acommon cause of ignition is heat from a failedbearing. Explosion relief valves open to releasethe pressure of an explosion - then close toprevent a second cycle of combustion. Basicallythey stop oxygen from getting in, which wouldper
