8.2 Accessories Additional Pulley (PTO)

The engines of the HPE range may be prearranged with an
additional power take-off on the engine shaft. This possibility
involves the installation of an additional pulley for trapezoidal
toothed belts with one or more grooves.

The pulley coupling with the accessory device must be
correctly sized. The technical features of the additional pulley
vary depending on the model of the engine and are expressed
in the following table:
