VALVE GP-ACCUMULATOR CHARGING 2702615 - Caterpillar

Pre-Start Checks And Procedures
1. Make a "walk-around" check of the engine and components. Correct minor adjustments before they develop into major repair jobs.2. Check the crankcase oil level. Maintain the oil level between the ADD and FULL marks on the dipstick. See the LUBRICATION AND MAINTENANCE CHART for proper type and viscosity of oil to use. D346, D348, D379 and D398 Engines are equipped with a combination sump pump and prelube hand pump. After a long shut down or after a filter and oil change, operate the hand pump to fill the oil passages in the lube system before starting. See the LUBRICATION AND MAINTENANCE PROCEDURES topic, Oil Filter Elements, before starting any one of these models of engines.3. Check oil level(s) on driven equipment. 4. Check the fuel tank level, See the LUBRICATION AND MAINTENANCE CHART for proper fuel to use. 5. Check the engine jacket coolant level. Maintain coolant level to the base of the fill pipe. See the LUBRICATION AND MAINTENANCE CHART for proper make-up coolant to use. 6. Open the raw water valve (if so equipped) on the engine jacket heat exchanger system.7. Reset shutoff devices. See the topic, ATTACHMENTS, Emergency Shutoff Devices and Alarms. 8. Open the fuel supply valve.
The fuel return line must be open to prevent engine damage.
9. If air has entered the fuel system, prime the fuel system. See the LUBRICATION AND MAINTENANCE PROCEDURES topic, Priming the Fuel System.
PRIMING PUMP ON 6 CYLINDER ENGINE
PRIMING PUMP ON V-ENGINE10. Disconnect any battery charger which is not protected against starting motor drain.11. Disengage the clutch, or open the circuit breaker on an electric set.
Do not start an engine under load.
12. Move the governor control lever to half engine speed position or to speed limiter stop. 13. Prime the raw water pump if necessary. (Only water pumps equipped with a water reservoir and fill plug require priming.) If the raw water pump is of the type shown below, the pump is a self priming pump. This pump does not have a priming chamber or fill plug.
SELF PRIMING RAW WATER PUMPPriming The Raw Water Pump:
The priming chamber must be filled with water before starting the engine to prevent pump or engine damage. After the engine is started, increase engine speed immediately to obtain and maintain system flow.
1. Carefully loosen the fill plug. If water is present immediately tighten the plug; the pump is full.2. If water is not present, pour approximately two gallons (7.5 liters) (1.5 Imp. Gals.), or until overflow occurs, into the fill hole.3. Install the fill plug.
FILL PLUG4. Start the engine at fast enough speed to obtain the normal water flow from the overboard raw water discharge or water cooled exhaust pipe.If the proper flow is not observed, stop the engine and repeat this procedure. If the pump does not hold water in the priming chamber, the water pump seals should be replaced.Starting The Engine
Do not engage the starter when the flywheel is moving.
Electric Starting:
1. Use starting aids if required. See the
