Insert the pin (1) in the seat on the rod (3). Drive the reverse
gear coupling fork (2) onto the rod (3), adjusting it so that the
pin (1) gets positioned in the bay (

→) of the fork (2).

Drive the ring (1) and the 1

gear coupling fork (3) onto

the rod (2). Position the fork (3) in the ring (1) so that on
turning it the bay (

→) of the fork (3) is inserted in the ring (1).

16 AS 2601 gearbox only, drive the 3

gear coupling fork

(1) onto the rod (2).

Position the fork (1) in the ring (3) so that on turning it the bay
(

→) of the fork (1) is inserted in the ring (3).

Position the fork assembly (2*-3) and the ring (1) assembled
in this way so that the bay (

→) of the reverse gear coupling

fork (4) is inserted in the ring (1).

Remove the inside rings (1-3) of the roller bearings from the
transmission shaft (2), using the extractor 99347100 (4), grips
993471132 (6) and plug 99345057 (5).

To fit the rings (1 - 3) on the shaft (2) it is necessary to first
heat them to 120

°C.

Heat the seat (3) of the cylindrical roller bearing (1) to ~ 90

°C,

fit this and fasten it to the middle box with the circlip (2).

If removed, refit the centring pins (4) after heating the seats
of the box to ~ 90

°C.

Fit the plate 99370153 (2) onto the middle box (1).

From inside the box (1), heat the seats of the rings (4) to ~
90

°C, transmission shaft bearings. Fit on the rings (4) with

driver 99370092 (3) and grip 99370007 (2).

Place the reverse gears (1) together with the roller bearings
(2) in the middle box.

Fit the fork assembly (1) onto the main shaft (2), verifying that
the forks are correctly positioned on their respective coupling
sleeves.

Mount the splitter coupling fork (1) positioning the plugs (2)
on the toothed coupling ring (3).

Fit tool 99360527 (1) onto the drive input shaft (8) and the
rods (2 and 3). Fit parts (5-6-7) of tool 99360526 (4) onto the
drive input shaft (8).

Hook the tool 99360526 (1) onto the lifter and fit the main
shaft assembly (5) in the gearbox, verifying that the shaft (5)
and the rods (3 and 4) get correctly inserted in their seats.

Remove the tools 99360526 (1) and 99360527 (2).

Mount the transmission shafts (1 and 3) so that on joining
them to the main shaft (2) the marks stamped on them are
aligned. Use the slots (

→) of the phonic wheel (4) to check

this.

COMPONENT PARTS OF THE MIDDLE BOX

* For the 16 AS 2601 gearbox only

With no gears engaged, the shafts must turn freely,
otherwise the alignment of the marks (see
Figure 108) will not be correct.

Figure 111

To perform the following operations, the gearbox
must be positioned as shown in Figure 110 in order
to avoid any chance of the reverse gears falling.
