a. Concrete steps
(1) Refill the fuel injection pump with fuel, and revolve the flywheel in clockwise direction to the
compression upper dead centre. Resolve the flywheel for several times until there is fuel flowing
out.
(2) Install the high pressure oil pipe tie which is used for measuring the oil supplying advance
angle, then resolve the flywheel to drain out the air inside. Stop the flywheel at 30° BTDC.
(3) Resolve the flywheel slowly in clockwise direction and check the oil level, stop the flywheel
immediately when oil begins fluctuating. The oil supplying advance angle is supposed to be 18.5°
±1°, if not, you should disassemble the fuel injection pump assembly, replace the adjust gasket,
check and adjust for another time until the value gets to 18.5°±1°.
(4) Screw on the fuel injection pump fixed bolt after adjusting and install the high pressure oil
pipe parts in turn.
Notice: Drain out the air in the high pressure oil pipe.
The rust and scale in the cooling system will worsen the heat abstraction performance and
increase the cooling water temperature. So please clean the rust and scale in the cooling system
by professional.
2.6 Check per 2000h running
2.6.1 Check and replace fuel、lube oil、cooling water and rubber hose. Check each kind of rubber
hose regularly; replace them if there is damage or aging.
2.6.2 Check and grind sealing ring belt of intake/exhaust valve. Please consult with the specialist
because professional skill is needed. You should check the sinking quantity of air door, width of
sealing ring belt and clearance between valve stem and valve pipe.
2.6.3 Check performance of fuel injection pump, this job needs oil pump experiment table, so
please consult with the specialist to maintain. You should check aiming point oil supply quantity,
starting oil quantity, oil supply uniformity of each cylinder, governor, maximum and minimum
stable rotation limit.
