360 Modena gear box manual - All Ferraris

• Fit the outer race of the rear tapered roller bearing (27) into the bushing (29) until flush, using the
base (a) and the tool AV 3255's punch (d).
• Position the inner race with rollers on the checking plane and rest the bushing with outer race.
• Make sure the bushing is level with the resting surface and re-set the dial gauge.
• Measure the distance “T 1 ” between the bushing plane and the bearing's inner race.
Taking into account a bushing pre-load of 0.03 mm, we will have:
S1 = R 1 + T 1 – 0.03
where “S1” represents the spacer thickness (26) to be inserted between the tapered roller
bearings.
• Fit the spacer (26), the bushing (29) and the bearing's inner race with rollers (27) on the lay shaft
and bring them flush using the press reusing the tubular punch (b).
