REMARKS:
1) References for which no letters or numbers are given are reserved for other injection pump
designs.
2) For a correct adjustment of injection pumps on the electric bench, conform to the manual
IVECO Technical Publications and Training No. XXXXXXXXX
3) Measurements taken on injection pumps equipped with ”KSB” must be performed with the
same at rest.
4) (*) LDA adjusting point: act on spring pre-loading ring.
5) After every variation of LDA pressure, act on the control lever.
6) For adjusting the starting point (ARF valve) add a 12.0 mm spacer to the third delivery stop.

The heat generated by the flow of current, heats the wax that
expands and causes pushing rod to come out, resetting the
lever (2) to position ”b” by degrees.
In this way the extra advance is cancelled, since the parts of
advance changer come back to their normal operating
position.
The full cut-out of KSB device is achieved after about 3-4
minutes of operation.
Description
Rotary injection pumps, with mechanical speed governor,
that are fitted on the engines dealt with in this publication, are
equipped with a cold injection advance automatic device
(KSB). This tool has the purpose of setting the injection
advance, below a given temperature, to a greater value than
that static one of pump fitting to the engine, and to reset it
by degrees to the value of this latter, as temperature rises.
Operation
KSB cold injection advance automatic device is a mechanical
type electric drive tool that mainly consists of a wax thermal
bulb (1) that acts on the advance changer control lever (2),
through a pushing rod and a connecting cable (3).
When starting a cold engine, the thermal bulb (1) pushing
rod, that operates on the connecting cable (3), is placed at
back position; consequently the lever (2) is kept in position
”a”.
In this condition the eccentric pin (4) (which is operated by
the lever (2)), changes the position of roll carrier ring (5) with
respect to its normal position and, in its turn, it causes piston
(6) to move, thus producing an increase of advance with
respect to the value of fitting static advance.
At engine start the resistance existing in the thermal bulb (1)
is supplied by alternator D
