Unseal of Diesel engine
After opened the engine packing container, the user should firstly check the engine and its accessories according to the packing list, check whether engine appearance is damaged and whether connections are loose, and then perform the following work:
(1) Wipe up the antirust coat and anticorrosive agent on exposed surface of the engine.
(2) Drain seal fuel in fuel filter and parts of fuel system out (It’s also allowed to start the engine without draining seal fuel in fuel system, but only can the engine be loaded after all seal fuel are consumed and normal diesel fuel is supplied in place). The users also need to pay attention to that storage life for diesel engine before unpacking is one year, for new diesel engine that has been stored for more than one year should be inspected and taken additional measures:
l Rotate the flywheel and spray solvent into engine intake tube, until all seal fuel in cylinders is expelled.
l Spray solvent into turbocharger intake and exhaust vent, until all seal fuel there is expelled.
l According to the service agreement with customer, we are obliged to add specified engine oil to engine without oil in oil sump; while for engine that has been filled with engine oil (with running-in accelerant) before being delivered, we suggest you replace the engine oil after run-in period (2000km or 50h).
l According to the service agreement with customer, for engine that has been filled with coolant before delivery under customer’s requirements, the coolant performance should be checked after unpacking, if the coolant is subjected to -30℃ or -35℃, its PH should be 7~8 (neutral) and hardness value should be 5~15°d [9~ 15°f (hardness)], otherwise, drain the old coolant and out and refill coolant with antifreeze additive.
(3) Check whether water blockage and grease blockage are unobstructed, check whether water temperature sensor and oil temperature sensor are in readiness.
NOTICE: Never start an engine before it is correctly installed and properly connected. When running the engine in enclosed environment, maintain good ventilation to ensure exhaust gas emissions into the atmosphere.
