Use of Genuine Parts
An engine consists of many parts which are mechanically
harmonized. To prevent engine faults in advance and use
engines with best performance for a long period, mainte-
nance and replacement of expendable parts should be
conducted regularly.
Use of genuine parts is recommended. Using unauthorized
or remanufactured parts may cause critical damage and
faults to engine for which Doosan shall not be held liable.
