2. Adjusting end of fuel delivery:
Note:
Engines equipped with Type PFR 1K 80A
439/2 injection pumps must be adjusted
to the correct end of the delivery stroke.
– Measuring procedure same as adjusting
start of delivery.
– Turn the crankshaft in the normal direc-
tion of engine rotation until the gauge
needle begins to move and the fuel
emerging from the overflow pipe starts
to drip slowly or ceases to drip.
– Continue to turn the crankshaft slowly
until the fuel just begins to drip from the
overflow pipe again (approx. 1 droplet
every 5 - 6 seconds).
– This point is the end of fuel delivery.
– The value obtained in this way must
agree with the desired value stated in
Section 4.
– If necessary, correct it as described
above.
3. Synchronising injection pump
delivery volume:
– Move the governor rod by hand fully to
the right, to the „Stop“ position, and
hold it there.
– Loosen all sliding elements (135/1) on
the governor rod; the toothed rack on
the flywheel-side injection pump must
be in the „Stop“ position.
– Move the sliding elements for the other
injection pumps to the right („Stop“ posi-
tion) until the pump toothed rack is
against its stop, and tighten there; see
Fig. 135.
– Release the governor rod.
– Before installing, coat the gaskets for
the cover and the starting charge device
on both sides with sealant H.
Apply the sealant only as a very thin
coating to the starting charge device, to
ensure that its oilway is not blocked
when assembling.
– Coat all bolt threads for the cover and
starting charge device with sealant D.

on:
The governor rod travel limit screw
(135/2) must be unscrewed during this
work, or else the „Stop“ point for the
pump governor rods will not be reached.
