(919) 823-4151, Telex #510-929-o695 Form 756006 Rev. 8183 . \''' A SAFETY PRECAUTIONS A AVOID ACCIDENTS Most accidents, whether they occur in industry, on the farm. at home or on the highway, are caused by the failure of some indi-vidual to follow simple and fundamental safety rules or precau-tions. For this reason MOST ACCIDENTS CAN BE PREVENTED by recognizing the real cause and doing something about it be-fore the accident occurs. Regardless of the care used in the design and construct1on of any type of equipment there are many conditions that cannot be completely safeguarded against without interfering w1th reasonable accessibility and efficient operation. A careful operator is the best insurance against an accident.

2 The complete observance of one simple rule would prevent many thousand serious injuries each year. That rule is: NEVER ATTEMPT TO CLEAN, OIL OR ADJUST A MACHINE WHILE IT IS IN MOTION. NATIONAL SAFETY COUNCIL A WARNING A On machines having hydraulically, mechanically, and/or cable controlled equipment (such as fork lifts. combmes. shovels, loaders, dozers, scrapers, etc.) be certain the equipment is lowered to the ground before servicing, adjusting and/or repairing. If it is necessary to have the hydraulically, mechanically, and/or cable controlled equipment partially or fully raised to gain access to certain items, be sure the equipment is suitably supported by means oth8r than the hydraulic lift cylinders, cable and/or mechanical devices used for controlling the equipment. A WARNING A ALWAYS USE proper tools and procedures as recommended in Service and Operator's Manual.

The engine crankcase is a cast iron unibloc with dry type replaceable cylinder liners, and with the housings for the crankshaft main bearings and valve tappets.

6 Helical-teeth timing gears, camshaft located in the crankcase and overhead valves; intake valves are shielded to increase turbulence of the aspirated air. The power train is driven by the crankshaft which revolves in four thin-shell main 14709 FIG. Three-Quarter Right Front View of Engine 1. First fuel filter; 2. Fuel Injection pump; 3.

Electric starting motor bearings and includes: Light alloy pistons with toroidal combustion chamber built in top, three piston rings (two oil scrapers and one compres-sion ring), forged steel connecting rods and liners lubrication and a second one through the small end for piston cooling. Aspirated air is filtered through an oil bath air cleaner.

7 Fuel is injected directly into the high turbulence combustion chamber built in piston top. Double diaphragm fuel lift pump, double filters connected in SERIES and water trap on the first filter. 14710 ' FIG. Three-Quarter Left Rear View of Engine With Clutch 12. Exhaust manifold; 13.

Separate four hole nozzles (360/460) or three hole nozzles (510) clamped to the cylinder head. Forced feed lubrication from camshaft driven gear-type pump with built in relief valve. Full flow filter screwed to the crankcase and pro-vided with an Internal relief valve which bypasses the oil flow when filter is clogged.

8 CIRCULATING WATER AND RADIATOR COOL lNG SYSTEM A centrifugal pump, belt-driven by the crankshaft-mounted drive pulley, forces the coolant flow which enters the radiator when the temperature reaches up to thermostat setting. The cold air drawn by the fan which is secured to the water pump hub, cools the coolant inside the radiator. Direct electric starting with solenoid engage-ment, 12 volt motor and starting aid for low temperatures. SPECIFICATIONS -ENGINE 360 460 510 Type .. Diesel .. Diesel ..

Check, by excluding one cylinder at a time, that the compression pressure drop is cons tant in order to ascertain the functional effi ciency and uniformity of nozzles or try once again using a set of calibrated test nozzles. 2. Look for the causes of poor engine perfor mance. Use a compression tester applying it in succession to each cylinder, to which the present test data and procedure refer.
