GENERAL INFORMATION

General Repair Instructions

1. Before performing service operation, disconnect
the grounding cable from the battery for reducing
the chance of cable damage and burning due to
short-circuiting.
2. Use covers for preventing the components from
damage or pollution.
3. Engine oil and anti-freeze solution must be
handled with reasonable care as they cause paint
damage.
4. The use of proper tools and special tools where
specified is important to efficient and reliable
service operation.
5. Use genuine DOOSAN parts necessarily.
6. Used cotter pins, gaskets, O-rings, oil seals, lock
washer and self-lock nuts should be discarded
and new ones should be prepared for installation
as normal function of the parts can not be
maintained if these parts are reused.
7. To facilitate proper and smooth reassemble
operation, keep disassembled parts neatly in
groups. Keeping fixing bolts and nut separate is
very important as they vary in hardness and
design depending on position of installation.
8. Clean the parts before inspection or reassembly.
Also clean oil ports, etc. using compressed air to
make certain they are free from restrictions.
9. Lubricate rotating and sliding faces of parts with oil
or grease before installation.
10. When necessary, use a sealer on gaskets to
prevent leakage.
11. Carefully observe all specifications for bolts and
nuts torques.
12. When service operation is completed, make a
final check to be sure service has been done
property.
13. Please refer to SB2088E00 manaul(D1146) for
the disassembly and assembly.
DE08TS Diesel Engines

Engine Specific Character

OMEGA combustion bowl

The OMEGA combustion bowl is a unit designed to
perform high efficiency, low emission combustion.
As the rim around the combustion bowl port of the
upper of the piston has been machined in a smaller
size than the interior of the combustion bowl, strong
swirl is produced in the combustion bowl and strong
squish flow makes the fuel be mixed more sufficiently
with air.
Due to the application of OMEGA combustion system
and optimal utilization of intake and exhaust port
configuration within the cylinder head, the DE08TS
diesel engines discharge very low level of hazardous
exhaust gases such as smoke, nitrogen oxide,
hydrocarbon, or carbon monoxide and thus ensure
high performance and low fuel consumption.
