TRANSMISSION

Transmission - Operating 4WD models

By adopting different bevel gear pairs, all of the listed mechanical transmissions can develop a speed of 40 km/h
(24.85 mph).
Models with standard front axle:
FRONT
11/28
With 20 " rear tires the bevel gear pair for all models is as follows:
FRONT
10/29
As a consequence of the use of the high pinion set, the synchronised power take−off has a different ratio between
the wheel speed and the take-off shaft speed.
With the previously noted bevel gear pairs, the new ratios expressed in power take−off per rear wheel revolution, are
listed below:
With all tires except for 380/70 R 20
With tire 380/70 R 20
NOTE: If the tires are changed, make sure that the new equipment bears the " A8" code on the side. Always observe
the inflation pressures as specified on tables.
