General Repair
1. Wait until the engine is properly cooled before starting work otherwise, you may get
burned by the heated engine. Before performing fuel line work, check the common
rail pressure and engine temperature by using the failure diagnosis device.
2. Disconnect the battery Negative (-) cable to prevent damage of wires and sensors
caused by a short circuit.
3. Engine oil and coolant may damage paint. Engine oil and coolant should be stored in
separate containers and marked for safe management.
4. Store the disassembled parts in a specified space to avoid damage or contamination.
5. Use specified and special tools for efficient and safe repair.
6. If parts need to be replaced, use only genuine Doosan parts for replacement. Using
unauthorized or non-factory remanufactured parts may cause critical damage and
faults in engine performance.
7. Replace parts such as cotter pins, gaskets, o-rings, seal rings, oil seals, and washers
with new ones during repairs. Reuse of parts may be the cause of engine faults
and engine may not operate properly.
8. Group and store disassembled parts in disassembling order. Bolts and nuts vary in
strength, shape, and torque according to their assembly position. Please divide and
store them accordingly to these characteristics.
9. Clean disassembled parts to remove foreign substances before inspecting or
reassembling parts. Use compressed air to clean the oil holes.
10. Thinly spread oil or grease on rotating parts or parts requiring lubrication, before
assembly.
11. If required, use a specified adhesive to assemble gaskets to prevent water or oil
from leaking.
12. Assemble bolts and nuts with the specified tightening torque.
