(1) Maximum moment of inertia of rigidly fixed additional masses.
(2) Maximum flexural moment due to radial forces relative to axis of first main bearing. The maximum flexural moment may be multiplied
by the factor indicated in the table in relation to the angular position between the additional radial forces and the axis of the cylinders (zero
is the top dead centre position with clockwise rotation).
Multiplication factor Angular position

2 15 ÷ 60
3 60 ÷ 105
4 105 ÷ 65

Torque PTO from the rear of the engine
Multipower PTO on engine fly-wheel
Certain models with a mechanical transmission (150E to 190EL with power outputs from 280 to 320 HP and 4x4) may be
equipped with the optional IVECO Multipower PTO, which is capable of handling higher torques than other PTO types. This unit is
fitted on the rear part of the engine and takes drive from the flywheel and is independent of the vehicle clutch drive; it is suitable
for use with the vehicle running and/or at a standstill (e.g. municipal applications, concrete mixers etc.).
Some precautions:
●
the PTO must be engaged only with the engine at a standstill (The Expansion Module offers a configuration that a safety
device prevents engagement with the engine running in any case);
●
the unit may be disengaged with the engine running but only if the output torque is nil;
●
the during engine must be started when no torque is being taken from shall be absorbed/consumed by the PTO.
▶
To guarantee correct engagement, the static moment of connected units must not exceed 35
Nm. According to the version of the connected units, it may be necessary to consider a clutch
engageable by load (weight) in the transmission.
The main technical and dimensional characteristics are given in Figure 4.3 and in Table 4.4.
