Workshop Manual S3.8 Engine A030K288 (Issue 2) 01-2010 Section 4 MAINTENANCE OF ENGINE LAID UP FOR LONG PERIOD For engines which are not likely to be operated for a long period the following maintenance operations are recommended to prevent deterioration : doing so. After the cylinder head cover has been removed and the inlet ports closed, the rocker arms, valves etc. should be sprayed with engine anticorrosion oil and the cover refitted. 1. Add 1% of water soluble anticorrosion oil to the cooling water in the radiator. Then run the engine until it is warm-water temperature should reach at least 60 0 C, so that the anticorrosion oil is distributed throughout the cooling system.
Then drain cooling water completely. 6. Batteries, which are not used, should be serviced at regular intervals, in order to keep them in good condition. Batteries should be stored in a cool and dry room. Check battery condition every fortnight and if necessary recharge. 2. For preserving the fuel system 5 to 10% of engine anticorrosion oil has to be added to the fuel in the fuel tank as well as to the oil in the housing of the injection pump. Then operate the engine for a few minutes. The above fuel mixture provides sufficient protection against corrosion even if the injection pump is not operated for a long period of time.
Then remove pump cover and spray pump elements and springs with engine oil containing 5 to 10% of anticorrosion oil. Screw on pump cover and spray outside of the pump with the mixture. 8. Cover up opening for air cleaner, exhaust pipe and engine breather pipe. The parking area should be airy and dry. PREPARATION OF ENGINE AFTER EXTENDED STORAGE PERIOD i . a . Check engine oil level, top up, if necessary. b. Remove injectors and check for spray and nozzle opening pressure. ii .Hold injection pump control lever in "stop' position. iii. a. Crank the engine with the help of starter 3. To preserve the engine, drain engine oil while it is hot and replace by recommended anticorrosion oil.
Then crank the engine for 5 seconds with the starter motor. until oil pressure is indicated on the gauge. Do not depress accelerator pedal. Cranking interval should be long enough to allow for battery recoveries. 4. For the protection of the cylinder walls remove the nozzles and inject 20 cc of anticorrosion engine oil into each cylinder. When doing so, the piston should be at the bottom dead centre. Refit nozzle and crank the engine with the starter motor for about 5 seconds. Before doing so, disconnect injection lines from the injection pump, so that b. Refit injectors. iv. Finally start engine in the usual manner. v.
The initial operation oil (running-in-oil) may remain in the engine for a short period of time (not more than 25 hrs.) after termination of the storage period. However, the oil should be drained as soon as possible and replaced by HD oil grade in accordance with the ambient temperature conditions. 5. Spray the unpainted parts of the engine with anticorrosion oil Rustban 339 compound. Cover the fan belt and rubber hoses before 18
