66 SEBU8325-01 Maintenance Section Engine Valve Lash - Inspect/Adjust Illustration 34 (Y) “MIN” mark. (X) “MAX” mark. g01165836 Illustration 33 Typical example Fill the Engine Crankcase g02659217 1. Remove the oil filler cap. Refer to the Operation and Maintenance Manual for more information on lubricant specifications. Fill the crankcase with the proper amount of oil. Refer to the Operation and Maintenance Manual for more information on refill capacities. NOTICE If equipped with an auxiliary oil filter system or a remote oil filter system, follow the OEM or filter manufacturer's recommendations. Under filling or overfilling the crankcase with oil can cause engine damage. NOTICE To prevent crankshaft bearing damage, crank the engine with the fuel OFF. This will fill the oil filters before starting the engine. Do not crank the engine for more than 30 seconds. 2. Start the engine and run the engine at “LOW IDLE” for 2 minutes. Perform this procedure in order to ensure that the lubrication system has oil and that the oil filters are filled. Inspect the oil filter for oil leaks. 3. Stop the engine and allow the oil to drain back to the sump for a minimum of 10 minutes. 4. Remove the oil level gauge in order to check the oil level. Maintain the oil level between the “MIN” and “MAX” marks on the engine oil dipstick. Engine Valve Lash - Inspect/Adjust i02171102 This maintenance is recommended by Perkins as part of a lubrication and preventive maintenance schedule in order to help provide maximum engine life. NOTICE Only qualified service personel should perform this maintenance. Refer to the Service Manual or your authorized Perkins dealer or your Perkins distributor for the complete valve lash adjustment procedure. Operation of Perkins engines with incorrect valve lash can reduce engine efficiency, and also reduce engine component life. Ensure that the engine can not be started while this maintenance is being performed. To help prevent possible injury, do not use the starting motor to turn the flywheel. Hot engine components can cause burns. Allow additional time for the engine to cool before measuring/adjusting valve lash clearance. Ensure that the engine is stopped before measuring the valve lash. The engine valve lash can be inspected and adjusted when the temperature of the engine is hot or cold.
SEBU8325-01 67 Maintenance Section Fuel Injector - Test/Change Refer to Systems Operation/Testing and Adjusting, “Engine Valve Lash - Inspect/Adjust” for more information. i02682385 Fuel Injector - Test/Change The fuel injectors should not be cleaned as cleaning with incorrect tools can damage the nozzle. The fuel injectors should be renewed only if a fault with the fuel injectors occurs. Some of the problems that may indicate that new fuel injectors are needed are listed below: • The engine will not start or the engine is difficult to start. • Not enough power Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. NOTICE Do not allow dirt to enter the fuel system. Thoroughly clean the area around a fuel system component that will be disconnected. Fit a suitable cover over disconnected fuel system component. NOTICE If a fuel injector is suspected of operating outside of normal parameters it should be removed by a qualified technician. The suspect fuel injector should be taken to an authorised agent for inspection. • Theenginemisfires or the engine runs erratically. • High fuel consumption • Black exhaust smoke • The engine knocks or there is vibration in the engine. • Excessive engine temperature Removal and Installation of the Fuel Injectors Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury. Make sure that you wear eye protection at all times during testing. When fuel injection nozzles are tested, test fluids travel through the orifices of the nozzle tip with high pressure. Under this amount of pressure, the test fluid can pierce the skin and cause serious injury to the operator. Always keep the tip of the fuel injection nozzle pointed away from the operator and into the fuel collector and extension. NOTICE If your skin comes into contact with high pressure fuel, obtain medical assistence immediately. Illustration 35 Typical fuel Injector g01347499 Operate the engine at a fast idle speed in order to identify the faulty fuel injector. Individually loosen and tighten the union nut for the high pressure pipe to each fuel injector. Do not loosen the union nut more than half a turn. There will be little effect on the engine speed when the union nut to the faulty fuel injection nozzle is loosened. Refer to the Disassembly and Assembly Manual for more information. Consult your authorized Perkins dealer or your Perkins distributor for assistance.
