III.5.4. Adjustment of fuel
injection timing
The correct setting of the
commencement of delivery is a basic
requirement for a troublefree function of
the engine. As the injection timing is
fixed, a check and respectively
readjustment is only necessary when
the engine speed was altered, a new
injection pump was installed or the
camshaft/camshaft gear was renewed.
Engines of model 15 and 18 are set at
„delivery cur off point“.
First crank the engine in rotation
direction to compression stroke till TDC
mark on the flywheel is approx. at the 5
o`clock position. Remove the allen head
screw from injector pump head and the
sealing washer under it and fit drip tube.
(Figure 10)
Attention:Fuel will flow out of the
pump as soon as the screw is
loosened.
Set acceleration lever at half load.
Attention: Excess starting fuel
buttom must not be pulled.
Slowly crank the engine rotationwise
and observe the drip tube. First the fuel
flows free out of it, drips, stops and
starts to drip again. The delivery cut-off
point is reached when approx. 1 drop
per second comes out of the tube.
