input shaft (3) from the main shaft (4), see Figure 68.

Remove the coupling sleeve (1) and the tube (2) from the
main shaft (4).

Turn the main shaft (3) upside-down and remove the coupling
sleeve (4) from it; remove the key (5) from the hole (

→) in

the shaft (3) and extract it.

If necessary, remove the circlips (1-3) from the gear (4) and
extract the toothed ring (2).

Put the synchronizing device assembly (1) on the workbench,
cover it with a cloth to prevent the pins (8) and springs (7)
getting lost during subsequent dismantling.

Holding back the synchronizing device ring (6), lift the
synchronizing device ring (2); these will get freed: toothed ring
(5), three clips (7) and three pins (8).

Fitting the splitter synchronizing device

Insert the three springs (7) and three pins (8) in the
synchronizing device ring (1) and keep them in their seat with
the centring pins 99370499 (2).

Position the toothed ring (4) on the synchronizing device ring
(6). Fit the synchronizing device ring (1) in the toothed ring (4)
and on the synchronizing device ring (6) so that the centring
pins 99370499 (2) drive onto the pins (5) of the synchronizing
device ring (6). Press on the synchronizing device ring (1)
uniformly so that the components of the assembly fit together
correctly. Take out the centring pins (2).

Insert the toothed sleeve (1) in the toothed ring (2) so that the race between the two toothings corresponds to the inside toothing
of the ring (2) and allows it to rotate.

Turn the sleeve (1) so that the hole in it coincides with one of the three bays (

→) of the toothed ring (1).

Then insert the key (3) as shown in the figure.
