SCREEN AS-SUCTION 9P9555 - Caterpillar

All gauges, panels and test instruments must be in correct operating condition before making any tests.The following publications and information are available from Caterpillar for Sea Trial Measurements:Introduction (Conditions for tests) Form SMHS7393 (Formerly GMG02354)D399, D398, D379 Form SMHS7395 (Formerly GMG02433)D349, D348, D346 Form SMHS7396 (Formerly GMG02434)D353 Form SMHS7397 (Formerly GMG02435)3408, 3412 Form SMHS7401 (New)3406 Form SMHS7402 (Formerly GMG02439)3306, 3304 Form SMHS7403 (Formerly GMG02440)3208 Form SMHS7404 (Formerly GMG02441)Caterpillar Marine Installation Information 40-684-82853Seal Trial Measurements of Caterpillar Marine Engines Engine Division - Engine Data Sheet 107 Form LEHM9182Technical Information File Marine Engine Sea Trial Data Fiche 226The reference material in the above list gives the information needed at the time that sea trials are made. Information given in these reference materials are: Conditions needed during the tests; normal, maximum or minimum values expected; illustrations that show the locations to make the tests. The numbers that follow the test locations are the same as those shown on the Caterpillar Marine Installation form, and on the general dimension drawings. Temperature and pressure tests must be taken at conditions that are typical of full load operation for the unit after engine temperature and pressure values are stationary.(1) Governor Rack Setting: See the Service Manual(2) Crankshaft Deflection (909): Take the deflection measurement at the center throw of the crankshaft before the engine is started. Refer to the Caterpillar Marine Engine Application and Installation Guide LE021575. This test is needed only on D399, D398, D349, and D348 Engines.(3) Voltage: Take this reading on the electric set from the vessel's instrument panel or from a voltmeter with all the switches on the vessel closed.(4) Amperage: Take this reading on the electric set from the vessel's instrument panel or from an ammeter with all the switches on the vessel closed.(5) Auxiliary Water Circuit-Pump Inlet Pressure (904): Take this measurement at the auxiliary water pump inlet with a pressure gauge like the gauge in the 4S6553 Instrument Group. The instrument used to take this measurement should show whether the reading is pressure or vacuum.(6) Auxiliary Water Circuit-Engine Outlet Pressure (905): Take this measurement at the engine outlet of the auxiliary water circuit with a pressure gauge like the 9S7370 Tetragauge Group. The instrument used to take this measurement should show whether the reading is pressure or vacuum.(7) Ambient Air Temperature: Measure the air temperature in a shaded area on the main deck of the vessel; use a thermometer like the 6H3050.(8) Ambient Sea Water Temperature: Measure the sea water temperature at the water depth of the sea water inlets or keel coolers; use a thermometer like the 6H3050.(9) Air Temperature at Engine Room Overhead: All hatches and doors must be closed with the vessel ready for bad weather. Measure the air temperature above the engine with a thermometer like the 6H3050.(10) Jacket Water Outlet Temperature (901): Take this measurement at the outlet of the jacket water circuit with a temperature gauge like the 9S9102 Thermistor Thermometer Group.(11) Jacket Water Pump Outlet Temperature (902): Take this measurement
