User Manual

To low down the oil temperature, an engine oil radiator or cooler can be added to
the diesel engine.
There'S a II Winter & Summer" valve on the connecting panel of
the
oil filter. When the oil temperature goes too high, we should turn the valve to II
Summer" end, and when the oil temperature is normal, we should turn it to II Win-
ter" end.
The engine oil enters into the main oil passage through the oil filter with-
out cooling.
The oil pump is of a internal and external rotor type, JZ x 2578 Model. There"'s a
pressure limiting valve installed
on the oil pump to control the oil pressure.
The oil filter is Model J080l , J08l2 on which a pressure adjusting valve is installed to
adjusted the oil pressure.
There'S also a bypass valve in the oil filter. When the oil filter or viscosity of the oil is
too high, the bypass valve will open, and the oil will el'1ters into the main oil passage
without being filtered through
oil cooler or filter to ensure the engine without authori-
zation.
Turbocharged diesel engine
has a model J0506 oil filter to filter the oil lubricating the
turbocharger.
The oil filter wick should be maintained regularly.
8. Cooling System
The engine adopts close (or open ) type forced circulation water cooling system,
which consists of the radiator
(or cooling pool), water pump, fan thermostat,
cowling, water inlet
and outlet hose etc. The diesel engine adopts centrifugal water
pump 'which
is installed at the front of the engine block and driven by the crankshaft
belt wheel through the V belt. If find the water - relief hole dripping water seriously,
you should change the water seal.
9. Electric System
The electric system of the 495, K4l00 series diesel engine has two types: l2V and
24V, both of which are single wire system with negative pole grounded. The rated
voltage of the motor
and other electrical equipment must meet the voltage require-
ment of the electric system.
The battery for starting is a power device of the diesel engine, its performance influ-
ence the start of the diesel engine directly, suitable capacity battery should be cho-
sen according to the starting motor"'s specific property. The battery should be in-
stalled near the starting motor so as to shorten the length of the cable between the
