Remove the rear eccentric hub (sec. 7 - 13, Removal of the rear wheel eccentric hub and rear wheel shaft).
Undo and remove the four fixing screws (13) of the brake disk to the wheel axle and remove the rear brake disk (14).
Loosen the four screws (24) and remove the rear phonic wheel (25).
The brake disc must be perfectly clean, with no rust, oil, grease or other dirt and no deep scoring.
To check the wear limit of the brake disk refer to sec. 3 - 1.1, Hydraulic brakes.
Place the rear brake disc (14) on the rear wheel shaft (26), by orienting the bevelled edges (s) faced upwards.
Fix the disc by starting the screws (13) with prescribed threadlocker.
Note
Make sure to centre the screw heads in the relevant seats on the brake discs.
Tighten the screws (13) to a torque of 27 nm +/- 10% (sect. 3 - 3, Frame torque settings), in the sequence 1-2-3-4.
Position the phonic wheel (25) on the brake disc (14) by orienting it as shown in figure.
Fix the phonic wheel (25) by starting the screws (24) with the recommended threadlocker.
Tighten the screws (24) to a torque of 5 nm +/- 10% in a crossed-pattern sequence.
Refit the rear eccentric hub as described in sec. 7 - 13, Removal of the rear wheel eccentric hub and rear wheel shaft.

Refitting the rear brake calliperRefitting the alternator-side crankcase cover
Before the assembly make sure that the water pump unit is fitted on the
generator cover (sect. 9 - 3.3, Refitting the
water pump).
If bearing (27) has been removed, lubricate its seat with specified grease to
fit it on the generator cover (13).
Fit bearing completely in its seat and orien ...
Cylinder compression test
Note
The on-screen icons used during this procedure are explained in a table at
the end of this section.
Engine performance is directly correlated to the pressure that can be
measured in the combustion chambers of the two
cylinders. Pressure which is too high/low or an excessive difference be ...
Anti-pollution system and auto-adaptive strategy
Efficacy of the catalytic converter and oxygen sensors
To comply with current emissions legislation, the diavel is equipped with a
trivalent catalytic converter, which oxidises co
(carbon monoxide) and hc (unburnt hydrocarbons) and reduces nox (nitrogen
oxides).
The image shows the exhaus ...
