WP13 Diesel Engine Series Operating Manual

◆
According to the agreement between the manufacturer and the user, if the engine has been
filled with coolant as the user requires, the coolant performance should be checked in time of
unsealing; if the coolant antifreezing ability can satisfy the needs for -30
℃
or -35
℃
, with its
PH value and total hardness value of 7-8 (neutral) and 5-15°d [9-15°f (hardness)], then such
coolant can be further used; if the requirements are not satisfied, such coolant should be
replaced by new coolant containing antifreeze additive.
4.2 Lifting of the Diesel Engine
In time of lifting, the engine should have its crankshaft centerline kept level, with tilting or
unilateral lifting strictly prohibited. Lifting and seating should be kept slow enough (see Figure
4-1).

4.3 Installation of the Diesel Engine
In time of installation, it should be guaranteed that the diesel engine has its crankshaft centerline
coaxial to the input shaft axis of the driving devices (gearbox, transmission or generator, etc.), and it
should be ensured that the crankshaft is subject to any additional axial force caused by installation.
4.4 Preparation before Starting
◆
Check the coolant level
If the engine has been installed on a vehicle or a bench, the coolant level can be seen through the
glass window on the expansion tank at any time, and if there is insufficient coolant, you can open
the coolant filler cover to add more. When opening any coolant filler cover provided with a pressure
relief valve and an exhaust button, you must first press the exhaust button if you want to open the
cover when the engine is still in hot state. Never fill with a large amount of coolant if the engine is
still in hot state. Otherwise, its parts will be damaged due to sharp changes of the temperature. If
there is no coolant in unusual circumstances, you can add cool water slowly from the coolant filler
until there is coolant flowing out. Start the engine, let it idling (1000 r/min), continue to add coolant
until the coolant level is kept steady, and finally cover the coolant filler.
◆
Check the fuel level.
If the engine has already been installed on a vehicle, open the power switch and check the fuel level
from the fuel gauge or check the fuel tank.
◆
Check the engine oil level
The oil level should be kept between the top and bottom scale lines on the oil dipstick, and more
engine oil should be added from the oil filler when necessary.
◆
Check the diesel engine accessories
Check whether the engine accessories are reliably connected and eliminate any abnormality. Check
