The axle is a bearing axle type with a simple reduction; it
consists of a box made in stamped steel sheet and properly
strengthened.
The differential consists of a reduction helical-toothed gear
pair (pinion — ring gear assembly) and a wheelwork box (side
pinion — crown wheel assembly).
The pinion is supported by two taper roller bearings and by
one straight roller bearing.
The adjustment of the bevel pinion assembly is made through
adjusting rings placed between the two taper roller bearings.
You can also adjust the bevel pinion position with reference
to the ring bevel gear by changing the thickness of the pack of
the rings, which are inserted between the differential box and
the bevel pinion support.
The wheelwork box is supported by two taper roller bearings
and can be adjusted axially through two threaded ring nuts.
The axle is provided with a pneumatic control differential
locking device.
The wheel hubs are supported by two taper roller bearings
floating on the tube, which can be adjusted by means of a
threaded nut.
