Iveco Daily. Manual — part 27
Auxiliary components are collected into one support (1)
fixed to engine upper block side and operated by the timing
belt which controls the camshaft.
On the mounting there are oil ducts, for lubricating the vari-
ous components.
The following components are fitted on said support: injec-
tion pump, oil pump and control valve, servo brake vacuum
pump and power steering pump, double-action oil filter and
heat exchanger.

Unscrew plug (5), remove spring (4) and control valve con-
sisting of piston (3) and barrel (2) from the cover (1).
Check that: piston (3) slides freely into barrel (2) and does
not show any traces of scoring and that spring (4) is not
broken or yielded.

For assembling accessory equipments group, invert oper-
ations described for dismantling it observing the instructions
described and illustrated here below.
Fitting operation of driven gear (2) on driving shaft (3) is to
be performed with a hydraulic press (1), by heating gear and
cooling shaft, so as a temperature difference of
~ 270°C be-
tween the two parts is found. Once fitting is completed,
check that a space of 88 - 0.2 mm exist between outer sur-
faces of gears.

Check the torque resisting rotation between the driven gear
and the oil pump driving shaft, proceeding as follows:
- apply tool 99360607 (2) to block rotation of gear (5);
- trace two reference marks (3) on shaft (4) and on gear
(5);
- operate on the driving shaft with a torque wrench (1)
calibrated at 64 Nm and tool 99360607;
- make sure the reference marks are perfectly aligned;
replace the parts if they are not.
