GEARBOX
Base - February 2003
The gears-controlling tie-rods bearing support is secured in the same chassis point on all models in the EuroCargo range, while the
adjustment tie-rod reaction plate is secured to the gearbox gears control in different positions according to the gearbox itself.

- Check or position, if disassembled, the gears control lever
on the transverse control: upon assembling the lever, the
milling (1) must correspond with the reference notch (2)
punched on the transverse shaft;
- position the gearbox in idle;
- in order to be sure about such operation, it is enough to
longitudinally push the transverse rod: if the rod performs
the movement, it means that it is in idle.

- It is necessary that the gearbox remains in such a
condition for the whole operation. In order to be sure of
that, in place of the Idle-R.M. switch, a screw can be
applied with equal sizes (M 16x1.5 mm) with its bit
chamfered at 60
° that, completely screwed, blocks any
transverse rod movement for gearboxes 2855.6 and
2865.6 and the internal controls for gear boxes 2870.9
and 2895.9; it is anyhow sufficient to check whether the
neutral condition remains during the different stages
(avoiding any forcing on the lever);
- position the reaction plate on gears control and screw the
securing screws without completely tightening them;
- check/adjust the length (X) of the gearbox control
reaction tie-rod that must be 329 mm;

with the shown dimensions (see Figures 5, 6, 7 and 8) with
a
