12
coupling for connection to make sure crankshaft centerline and output shaft axis to be coaxial
and also ensure crankshaft doesn’t bear extra axial force for improper installation. The
co-axiality between crankshaft centerline and gear box output shaft centerline should be less
than 0.2mm; and face run out is less than 0.2mm. The co-axiality adjustment is as shown in
figure 3-2.
During use, users should regularly check as per the above requirements. Adjust it if
necessary to make sure normal running.
3.3 Other engine accessories installation
1) Engine exhaust pipe should be connected to outdoor. And its exhaust pipe should not
have too many bending. Expansion joints should be fitted in the middle of pipeline; and
additional support should be added. The inner diameter of exhaust pipe shouldn’t be less than
50mm and back pressure should be more than 6Kpa.
2) The exhaust pipe exit outdoors should be covered with rain shield. Water drain plug
can be fitted in the lower place of exhaust pipe to make condensed water in exhaust pipe drain
away.
3) The air intakes outdoors ( especially marine engine) should be fitted with waterproof
cover to avoid water entering intake system.
4) The fuel tank capacity should meet 8-hour running with rated load. The fuel pipe
diameter should not be less than 10mm.
4. Operation and Maintenance of Diesel Engine
4.1 Preparation and inspection before operation
Open the package and sealing
When opening the engine package, users should first count the number of diesel engine
and fittings according to the packing list; and check whether there is any damage on the
engine surface and whether the connection is loose or not. Then proceed to the following step:
1) Wipe anti-rust coat and corrosion inhibitor of engine parts exposed outside.
2) Drain out the seal fuel in fuel filter and inside of spare parts of fuel system. (It can be

LAMBERT POWER Diesel Engine Operation and Maintenance Manual
13
allowed to start with the seal fuel in fuel system; but only when the seal fuel in fuel system is
run out. it can’t be given full load until the fuel supply is normal.)
The seal period is one year. Over 1 year it must be checked
and taken necessary measures.
3) Rotate flywheel and spray solvent to inside of intake pipe until the oil seal oil in
cylinder is eliminated.
4) Spray solvent to turbocharger intake and exhaust hole until the oil seal oil is
eliminated.
5) Check oil in the oil sump to make sure the level is as specified.
6) Check the coolant to make sure it’s as specified.
4.2 Inspection before start
Check coolant level
If engine has been fitted on the base frame, see the coolant level. If the coolant level is
low, open radiator cover and add coolant. Never add a large amount of coolant when engine is
hot. If there is not enough coolant at top urgent conditions, slowly add moderate temperature
water until it overflows; start the engine, continue filling water to be full till the level is stable,
finally cover radiator cap.
Check oil level
Oil level should be between upper and lower scale mark of dipstick. If necessary,add oil.
Check whether various accessories connection is reliable, rectify if there is problem.
Check whether wire connection in electric system is normal and battery is fully charged; then
open fuel tank valve to connect hand fuel pump to expel the air in fuel system.
4.3 Engine start
Set power switch and electric key to “start”position, then start the engine.
4.4 Normal running conditions

Temperature for coolant exit 75～95℃
Exhaust temperature after turbo≤600℃
Intake temperature after air intercooled 55±5℃
4.5 Cautions in use
While starting engine, if it does not start successfully within 15 seconds, re-start after 2
minutes interval. If it can’t be started by three successive starts, stop starting immediately.
Find out the reason, trouble shoot and then restart..
After engine start, run several minutes at idle speed, then raise the speed to rated speed
and add the load. Only when outlet water temperature is higher than 60℃and oil temperature
is higher than 50℃, engine can run at full load. The add of load and speed should be given
gradually. Never add or reduce the load suddenly.
4.6 Engine operation in winter
Fuel: Choose different grades of fuel according to the outdoor temperature in winter.
Lubricating oil: Choose different viscosity of lubricating oil as per different seasons.
Coolant: Choose different grades and amount of coolant as per the outdoor temperature
in winter.
Start: In winter , if necessary ,use auxiliary starter. After engine start, when oil
temperature and water temperature are normal, apply the load and run at high speed
Battery: Before cold season begins, do check electrolyte level, viscosity and unit
voltage
Engine stop
Under the cold season when stopping engine, fist take off the load, and then run it for 5
minutes at idle speed. When the temperature comes down, it can be stopped. If coolant is not
added antifreeze additive, open water drain valve or water seal plug in cylinder block side,
radiator and inlet water pipe to drain out coolant in case of frost crack.
5. Periodic checkup and technical maintenance
Correct maintenance and upkeep of engine is the important step to ensure engine to work
