Injection pump assembly
After having dismantled the injection pump it should be
reassembled in the following manner:
1.Insert cylinders into pump casing with diesel inlet opposite to
feeding inlet connection (fig. 36). This position is necessary
due to two eccentric dowels on the pump casing.
Make sure the supporting faces of the cylinders and pumps are
free of dirt.
2.Fix cylinders by inserting valves and temporarily tightening the
delivery connections to stop the pumping elements from
coming out. (fig. 37).
3.Insert rack bar and lock in a half way position (fig. 38). Make
sure the bar moves freely on the guides. Resistance and drag
will cause the engine to run unevenly.
4.Marks b cut on the bar must coincide with marks a of the
toothed quadrants. Marks c on toothed quadrants must
coincide with marks d on the flanges of the piston (fig. 39).
5.Insert piston into cylinder with groove turned towards the
eccentric dowel on the pump casing.
6.Complete assembly of pump.
IMPORTANT: The roller tappets (No 8 fig. 34) and the
lower plates are not interchangeable as they determine
the timing of the pumping elements.
When replacing parts make sure that:
a.the distance between the injection cam in bottom dead centre
position (PMI) and the pump supporting surface is
82.6 to 83 mm as stated on the plate.
b.the piston stroke from the bottom dead centre position (PMI)
of the injection cam to delivery commencement is
2.0 to 2.1 mm for Ø 6 and 7 mm pumping elements and 2.2
to 2.3 mm for Ø 8 mm pumping elements.
7.Check pressure seal again, as described in paragraph
"Checking injection pump" page 26, to make sure the replaced
parts are working properly.
