1. In order to reduce the number of gearbox com-
ponents, the gear system has been altered. At the
same time, in order to decrease the possibility of
oil leaks, the possible oil leak sections have been
reduced.
2. In order to improve rigidity, the gear transverse
section has been changed, from the conventional
"U" to the cylindric shape.
3. To reduce weight, each housing has been made
in aluminium die-casting.
In addition, there are special ribs on each housing
which allow to obtain a compact design and a
weight reduction.
