Pegaso 650 I.E.
7.3.2 REMOVING THE FINAL DRIVE UNIT
Carefully read 0.5.1 (PRECAUTIONS AND GENERAL
INFORMATIONS).
N
Remove the rear wheel, see 7.3.1 (REMOVING THE
REAR WHEEL).
NOTE
The support plate (8) complete with brake cali-
per (9) remains mounted on the left side of the rear fork.
Proceed with care. If the final drive unit (10) is installed on
the flexible coupling holder (11), do not overturn or rotate
the rear wheel in horizontal position on the rear sprocket
side, since the final drive unit would come off and fall
down, with the risk of damaging the rear sprocket (7).
NOTE
The removal of the final drive unit isn't neces-
sary if the wheel is in the normal running position (verti-
cal) or in horizontal position with the rear sprocket facing
upwards and in both cases secured against overturning.
NOTE
Do not unscrew the six nuts (12). The whole final
drive unit must be withdrawn from the flexible coupling hold-
er.
N
Withdraw the final transmission unit (10), keeping it
parallel to the wheel axis.
N
Remove the four flexible couplings (13) from the flexi-
ble coupling holder (11).
NOTE
Check the conditions of the four flexible couplings
(13); if they are damaged or excessively worn, change
them, see 2.1.1 (REGULAR SERVICE INTERVALS
CHART).
REASSEMBLY
NOTE
Insert the final transmission unit, parallel to the
wheel axis, introducing the drive pins in the relevant seats,
between a flexible coupling and the other.
N
Position the four flexible couplings (13) in the relevant
seats in the flexible coupling holder (11).

Insert the final drive unit in the flexible coupling holder
(11).
