2.2.28. Fuel injection pump z Check the housing crack, damage etc. and replace it if abnormal. z Check if the idle operation and speed regulating lever’s sealing is removed. z The adjustment and testing of fuel injection pump should necessarily be done at the test bench. 2.2.29. Battery z Inspect for any leakage of electrolytic solution owing to battery crack, and replace the battery in case of poor condition. z Inspect for amount of electrolytic solution, and replenish if insufficient. z Measure the gravity of electrolytic solution, if less than specified value (1.12 ~ 1.28), replenish. 1,100 1,200 UPPER LEVEL LOWER LEVEL 1,300 EFM1007I 2.2.30.
Air removal of fuel system The suction room of fuel injection pump has the function of air removal continuously during the operation through a relief valve. Iin case that the suction room lacks fuel at all, for instance, in case of new installation of injection pump, after loosening the air removing screws of cartridge filter respectively, remove the air by operating the manual pump of fuel supply pump until bubble will disappear. 2.2.31. Fuel supply pump Every time of engine oil replacement, the fuel strainer installed at the fuel supply pump should be removed and cleaned. 2.2.32.
Supercharger The supercharger needs not arty special equipment Every time of engine replacement, a leakage or clogging of oil pipes should be inspected. Air cleaner should be maintained carefully for nut or foreign material not to get in. Periodic inspection should be applied on the compressed air and exhaust gas pipes, For leaking air will bring the overheat engine, an immediate repair must be done. During the operation that is surrounded by the dust and oil mixed air, frequent cleaning must be done on the impellers. Tear down the impeller casing (attention: be careful not to bend) and must clean with non-acid solvent solution.
If necessary, use plastic scraper If impeller is severely polluted, dip the impeller into solution and may be better to clean it with stiff brush. housing. Then one thing to beware is to dip only impeller part and so do not support by impeller but bearing Technical Information - 38 -
