360 Modena gear box manual - All Ferraris

The deviation “t” compared to the theoretic value 45.10 mm is marked by the Manufacturer on
the differential crown and corresponds to the distance between the crown's rear surface and the
pinion axle.
The real distance “G” between the crown's rear surface and the pinion axle will be:
G = 45.10 ± t
To determine the total size (“L”, see Fig. 1) of the differential assembly pack with bearings and
spacers, calculate:
L = R – V
To determine the size (“H”, see Fig. 1) from point “0” to the tip of the right-hand bearing,
calculate:
H = X – G
At this point, we are able to determine the thickness (“S1”, see Fig. 3) of the spacer (12):
S1 = R – S – H
To obtain the thickness (“S2”, see Fig. 3) of the spacer (7), take into account the new bearing
pre-load of 0.07 mm and calculate
S2 = L – W – S1 + 0.07 mm
