Iveco EuroCargo (12 to 26 t). Manual — part 90

Mount snap ring (1), the thickness of which produces axial play
of the same, into its own seat (2), as near to zero as possible.
Check axial play of 2

nd

speed gear (2), which must fall within

the range of 0.35

÷ 0.48 mm.

Heat hub (2) to a temperature of 85

°C, then fit it onto output

shaft (1) so that:

- the higher shoulder faces downwards (see relevant

section);

- the narrower openings (3) are inserted into the

synchronizing ring projections (4);

- the wider openings (7) of the hub are aligned with

synchronizing ring openings (5) and inner ring tabs (6).

Check the amount of wear of synchronizing rings by acting as
follows:

- Visually check that the friction surface is not corrugated.

Rotate synchronizing ring (1) so as to ensure correct match on
matching body (2).
Use a thickness gauge (3) to check, on two diametrically
opposed points, the clearance between the two parts.
If the measured value does not fall within the range of 0.5

÷

1.9 mm, replace the synchronizing ring.

Mount roller cage (2), 2

nd

speed gear (3) and matching body

(4) on output shaft (1).
Mount inner ring (5) and intermediate ring (6) so that the tabs
are inserted into the matching body (4) slots, then mount
synchronizing ring (7) so that the outer side openings match
with ring (5) inner tabs.

!

The synchronizing rings must, after inspection, be
marked on their respective matching bodies in order
to

avoid

exchanging

their

position

when

re-assembling.

Mount sliding sleeve (2) on hub (1) by turning it in the
direction shown in the figure.
Mount dowels (6), springs (3), dowels (4) and balls (5), then
secure them below sliding sleeve (2).

Mount synchronizing ring (7) so that its projections (8) are
inserted into the narrowest openings of hub (9).
Mount inner ring (5) and intermediate ring (3) so that the inner
tabs (4) of the latter match with the outer side openings of
synchronizing ring (7).
Mount matching body (1) so that the slots (2) of the same are
inserted in the tabs of ring (5).

Lubricate roller cage (3), then fit it onto output shaft (1).
Mount 1

Heat hub (4) to a temperature of ~ 85

°C, then fit it onto

output shaft (1).
Mount snap ring (2), the thickness of which produces axial play
of the same into its own seat (3), as near to zero as possible.
Check axial play of 1

speed gear (5), which must fall within

the range of 0.40

÷ 0,57 mm.
