Mount the selection and engagement levers (1) on their
respective shafts (2) and fasten them with the spring pins (3).

Check the assembly of the selection (6) and engagement (3)
levers.

The selection (6) and engagement (3) levers must be
mounted on their respective shafts so that:

- between the c/c distance of the pin (5) of the selection

lever (6) and the outside of the bracket (1) there is a
distance X of 134 mm;

- between the c/c distance of the pin (2) of the engagement

lever (3) and the outside of the bracket (4) there is a
distance Y of 135 mm.

If a different value is measured, orientate the lever concerned
on the respective shaft appropriately.

Then tighten the nuts for the screws to the required tightening
torque.

Thoroughly clean the mating surfaces of the gear control box
(2) and apply LOCTITE 5206 sealant on them.

Fit the box (2) on the transmission, taking care that the levers
and shafts are positioned correctly in their respective seats.

Tighten the screws (1) to the required torque.
