Checking and adjusting start of fuel delivery

Fig. 5
Remove screw plug (1) on governor housing.
If fitted, take out blocking pin (2).
If the pointer is exactly in the centre of the
inspection hole, the pump plunger for cylinder no.
1 is at start of delivery. However, it is possible to
determine exactly whether or not the pump is at
start of delivery only by means of the following
special tools:
a. Light signal transmitter
Fig. 6
Push light signal transmitter into socket in gover-
nor housing. Ensure that the lug (3) fits in the
groove (4). Tighten the knurled nut (5) by hand.
Connect up power supply of light signal transmitter
(red terminal = +). Turn engine by hand so that
piston in cylinder no. 1 in the compression stroke
comes close to the start of delivery.
Lamp (A) comes on shortly before start of delivery
is reached.
Fig. 7
Slowly turn the engine further until lamp (B) comes
on too. The injection pump is now at start of
delivery.
The light signal transmitter KDEP 1600 (Fig.) is
connected to the starter battery for the power sup-
ply.
Note:
If only lamp (B) comes on during this test,
the engine has been turned past the start of
delivery. In this case turn the engine back
and repeat the procedure.
