4. Adjusting effective stroke:
(on engines with start of delivery
adjustment)
– Install the start charging device and
replace the cover by hydraulic starting
charge adjuster 619 845 00;
see Fig. 136/3.
– Set the speed control lever to full load
and secure it there.
– Insert the overflow device with dial
gauge, as described in the section
„Adjusting start of fuel delivery“.
– Connect the fuel feed line from the test
tank and open the shutoff tap; fuel will
emerge from overflow device.
– Turn the crankshaft until the injection
pump has just reached the start of fuel
delivery (approx. 1 droplet of fuel emer-
ges every 5 - 6 seconds).
– Set the dial gauge to zero and continue
to turn the crankshaft in the normal di-
rection of engine rotation until the dial
gauge moves from „0“ to precisely the
nominal effective stroke value stated on
the type plate.
– In this position, fuel should start to drip
out of the overflow device again.
– If this is not the case, loosen grub
screw (136/2) and turn the eccentric
flow limiter (136/1) until the fuel begins
to drip out slowly.
– When the setting is correct, retighten
grub screw (136/2), seal it with lacquer
and install the cover again in place of
the adjuster (136/3).
