Figure 1 shows all the parts to be reassembled on the gearbox primary shaft (2), with the calculated end shims (1) and (11) (sec. 9 - 9.2, Reassembly of the crankcase halves).

Figure 2 shows all the parts to be installed on the gearbox secondary shaft (25), with calculated end shims (15) and (26) (sec. 9 - 9.2, Reassembly of the crankcase halves).

Reassemble the gears on the gearbox shafts by reversing the disassembly procedure.
Take particular care when installing the idler gears. The assembly of the 3rd and 4th speed gears and the relative fixing components on the secondary shaft is given as an example.
Fit the circlip (7), checking that it is fully inserted into its groove on the shaft. Push the circlip into position with a suitable size tubular drift.

Slide the washer with three internal points (6) over the shaft until it locates against the circlip you have just fitted.

To fit the needle roller cage (4) onto the shaft, first lubricate it with plenty of grease (of recommended type) and then open it slightly to make it easier to slide on to the shaft.
Fit the 3rd speed gear (22).


Fit on the gear the three-pointed washer (12), which can be distinguished from its counterpart (6) by its bigger outside diameter.

Fit another needle roller cage (4) using the method already described.
Fit the 4th speed gear (21).


Fit another safety washer (6) and another circlip (7) into the shaft. Push it inside its seat using the previously used pad.

Reassembly of the gearboxInjection and ignition
Introduction
Ignition is via a single stick coil per cylinder installed in the spark plug
well. Each thermal unit is supplied by a single
injector, placed under the throttle valve. The amount of fuel injected and the
ignition advances are determined by the
control unit specifically for each c ...
Overhauling the rear wheel
Inspect the condition of the rear wheel.
As the wheel rim has no bearings, it should be supported using the service tool
code 88713.2951.
Note
This service tool can also be used to install the wheel on a balancing
machine.
Overhauling the wheel
Inspect the wheel as described below.

Removal of the clutch
Note
For clarity, the figures show the engine removed from the frame.
Undo the fixing screws (1) and remove the ring (2) and the springs (3) from
the pressure plate (4).
Slide the pressure plate (4) paying attention to the circlips (6).
