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.

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 (
