4 MAINTENANCE
4.1 Alternator
The alternator does not require any maintenance. Periodic in-
spection and cleaning is recommended, depending on environ-
mental conditions.However when the alternator has been idle for
a long period attention to winding condition is recommended.
The condition of windings can be assessed by measurement of
insulation resistance to earth. (See 5.3.5 Meggering)
The alternator bearing is greased for life and is therefore not
regreasable.
4.2 Engine
4.2.1 Preliminary instructions
All regular maintenance can be carried out when the enclosure is
open. When oil and dirt has gathered in the enclosure measures
have to be taken to avoid spilling oil and polluting the environ-
ment.
The first service on the engine should be carried out after 50
hours of its life and after a major overhaul. In the first 50 hours
the engine should receive special attention:
Long periods of light or no load running in the first 50 hours may
lead to cylinder glazing and high oil consumption.
For the same reason it is of the greatest impor-
tance to use the right oil specification.
The first time starting up or after running out of fuel it could be
necessary to prime the fuel system.
4.2.2 Bleeding fuel lines
Ensure there is sufficient fuel. The Whispers are self- bleeding. To
check the well-functioning release the bleed screw on the high
pressure fuel pump. Turn loose the cap of the fuel lift pump, and
move the piston up and down to prime the system. Retighten the
bleed screw when no further air bubbles are expelled. Retighten
the cap when ready.

4.2.3 Valve clearance
When the engine is in cold condition both valves (inlet and out-
let) should have a clearance of 0.25 mm. The adjustment has to
be done at TDC (see 5.4.2).
4.2.4 Replacing fuel filter
Filter change depends on contamination of the fuel, but should
be done however, at least every 300 running hours. A clogged
filter results in a lack of output of the generating set.

4.2.5 Replacing oil filter
Replacement has to be executed according to the schedule in this
manual. Drain the oil using the sump pump and put some tissues
under the filter.
