Checking for wear
The 1 st - 2 nd , 3 rd - 4 th and 5 th - 6 th speed synchroniser rings are similar to each other, but different
from those of the reverse gear.
Visually check that the male cone does not show signs of smoothing, excessive seizure or
overheated areas.
To check the reverse gear synchroniser wear, proceed as follows:
• Centre the synchroniser ring (E) on the corresponding friction cone. By a relative axial rotation,
the two cones should be positioned so to couple in a uniform and parallel way.
• Measure the gap between the engaging element and the synchroniser ring at several
diametrically opposed points (Fig. 5).
To check the 3 rd - 4 th and 5 th - 6 th speed synchronisers for wear, proceed as follows (Fig. 6):
• Make an assembly pack by centring the lined intermediate synchroniser ring (H) in the outer ring
(E) and inserting the inner ring (L) into the intermediate ring. Make sure the couplings are parallel
