360 Modena gear box manual - All Ferraris

Re-assembling the gearbox shaft components
IMPORTANT
The correct positioning and the end float of the gears on the main and lay shafts is determined by
the shoulder rings. Check the thickness of these rings every time a component in the assembly pack
is replaced. It is possible to keep the same shims only if the new component shows a deviation
which is lower or equal to 0.02 mm, in respect of the replaced component's thickness.
Main shaft
Use the tool AV 3252 composed of the base (a), different punches (b, c and d) to reassemble the
components on the main shaft.
• Position the main shaft on the base (a).
• Using the punch (b) bring the 5 th speed gearing (9) flush with the main shaft.
• Fit the complete 5 th and 6 th speed synchroniser (11) on the shaft and bring the elements flush
using the punch (b).
• Fit the 6 th speed spacer (13) with its released side resting on the flexible ring (12) retaining the
4 th - 5 th speed hub.
• Fit the roller cage (10) and the 6 th speed gearing (14) on the shaft.
