General notes on engine overhaul
9
The service life of an engine is influenced by very different factors. It is therefore not possible to specify
certain fixed numbers of operating hours for general overhauls.
In our view, it is not necessary to open up and engine or perform a general overhaul as long as the engine
has good compression values and the following operating values have not changed significantly in relation
to the values measured on commissioning the engine:
D
Power
D
Exhaust temperature
D
Coolant and lubricant temperature
D
Oil pressure and oil consumption
The following criteria greatly influence the length of the engine service life:
D
Correct power setting in accordance with conditions of use
D
Technically correct installation
D
Inspection if installation by authorised personnel
D
Proper design and setting of and supply to the mixture formation system and the
ignition system
D
Selection and quality of lubricants, gas and coolant
