FUEL TRAP

Fuel by-passed at the fuel filter housing is returned to the trap rather than the individual tanks, thereby eliminating the danger of overflow.

If any of the tanks are so mounted that there is a suction lift required, then it will be essential that all of the other tank connections be tightly closed by the valves shown, or the suction lift of the pump will be broken by air leaks from another tank.

FUEL LINES

Flexible fuel lines (2) and (3) are recommended on all installations. Connect a fuel line from the Diesel fuel tank to the fuel transfer pump flexible line (3). The transfer pump will lift fuel the height of 12 feet through no more than 50 feet of pipe, Also, remove the cork and con-nect a return line from the fuel filter adapter (1) to the top of the Diesel

tank or fuel trap if so equipped. It is essential that there be no air leaks in the suction system. Even a small leak will destroy the suction lift of the transfer pump.

CAUTION

Do not connect a line between the adapter (1) and the fuel inlet to the fuel transfer pump as this may cause the system to become air bound. If a pipe plug is installed in place of the cork or if the return tube is too smalt fuel pressure will burst the housing.

EXHAUST LINES

Flexible connections should be used to prevent transmission of engine vibrations to exhaust piping. Flexible metal tubing is generally recom-mended for the exhaust connection at the engine. The exhaust outlet should be protected from the weather so that rain and snowc:;annot enter the line and get into the engine. The exhaust lines should be as short as possible. Long exhaust lines or lines with several bends should be of increased diameter so as not to create excessive back pressure. The back pressure should never exceed 25 inches of water on a new installation when measured with a manometer at the exhaust connection of the engine. Exhaust from the starting engine should be carried in a separate line and not connected into the Diesel exhaust line.

ENGINE MOUNTING AND SHAFT ALIGNMENT

Coupling Alignment: Extreme care should be exercised in the align-ment of the engine and propeller shaft. The alignment of the reverse gear coupling and the propellor shaft coupling should be checked after the vessel has been launched as hull distortion sometimes takes place after the vessel is in the water. Uncouple the propeller shaft from the reverse gear and see that there is less than .005 inch (.126 mm.) variation on a 9 inch (22.86 cm.) diameter. If the variation is greater than this amount, alignment can be restored by adjusting the leveling capscrews. Hold-down bolts or lag screws should be of such diameter as to make a tight fit in the hole of the support bracket. This is necessary to prevent movement of the engine on its supports. At frequent intervals, check this alignment especially in freight boats. Failure to keep the engine and propeller shaft in alignment would cause damage to the various reverse gear parts and propeller shaft bearing.

Reverse Gear Installation: When a reverse gear is not installed at the factory or is removed and reinstalled, care should be taken to insure correct alignment between the reverse gear and the engine. Improper alignment will result in undue wear or damage to the reverse gear mech-anism. It is recommended you consult your "Caterpillar" dealer for specific information on installing a reverse gear on the Diesel engine.


INST ALLATION INSTRUCTIONS 9

ELECTRICAL EQUIPMENT

Battery Installation: The voltage regulator furnished with ~2 volt electric starting systems is adj usted for use with 15 battery cells or 30 volts as stamped on the plate on the regulator. If for some reason it is necessary or desirable to use 16 battery cells the voltage regulator should be readjusted by your "Caterpillar" dealer before the engine is started.

Voltage Regulators: When the engine is equipped with a charging generator it may be advisable to mount the voltage regulator at some location other than on the engine. This will reduce to a minimum, any damage or irregular operation of the voltage regulator which might be caused by vibration or oil and water from the engine .

tually leading to objectionable deposits in the engine. When the oil darkens, therefore, it is an indication that it is keeping the engine clean and insuring satisfactory lubrication per-formance.

(CO) Superior Lubricants (Series 2): Lubricating oils known as Supe-rior Lubricants (Series 2) for "Caterpillar" Diesel Engines should be used in the Diesel Engine crankcase for most satisfactory service. The excep-tional value of these oils is in the fact that they have long service life. Long service life of the oil provides for less frequent oil change periods as well as extending engine service life. In addition to having the quality of long service life they combat detrimental effects of high sulphur fuels.

See the following chart for recommended oil change periods.

* As the fuel sulphur content increases bet'Ween 1.0'10 and 1.5% it may be necessary to make oil change periods more frequently.

If Superior Lubricants (Series 2) are not available crankcase lubricat-ing oils meeting in the requirements of MIL-L-2104A specifications can be used successfully in the Diesel engine crankcase when the fuel sulphur content is less than 0.4 %. For the recommended oil change periods see the following chart.
