ENGINE DISASSEMBLY
Workshop Manual Ed. 09-2011
Chain sprocket removal
– Remove the circlip ( 1 ) and slide the chain sprocket out of the output shaft.
– Slide the spacing bushing out of the output shaft using needle-nose pliers.
Splitting the crankcase
– Turn up the ignition side and remove all screws from the casing.
– Remove the engine retainers on the installation stand.
– Detach the right crankcase half using suitable tools correctly positioned in
the relevant places, or gently tapping on the output shaft and crankshaft with
a plastic hammer.
AVOID SEPARATING THE CRANKCASE HALVES WITH A SCREW-
DRIVER OR SIMILAR TOOLS THAT CAN EASILY DAMAGE THE
SEALING SURFACES.
Gearbox control and shaft removal
– Remove the left crankcase half and the relevant gasket.
WARNING: While removing the left crankcase half be careful not to damage the
washers on the input shaft and the selector drum. They can be fastened inside
the crankcase half.
– Remove the thrust washer ( 3 ) and the shim ( 2 ).
– Slide the 2 centring bushings out of the casing.
– Remove the O-ring from the output shaft.
– Fasten the right crankcase half onto the installation stand.
– Pull up the fork guiding rods (
4
) by nearly 1.5 cm and move them aside to-
gether with the gearbox forks ( 5 ).
– Remove the selector drum ( 6 ) with the relevant shim (if any) from the cas-
ing.
WARNING: The shims on the selector drum compensate the axial clearance.
Upon reassembly they must be refitted in the original position.
– Remove the fork guiding rods and the gearbox forks from the casing.
WARNING:
– The gearbox forks of the output shaft are the same, but despite that, they
should be refitted in the original position.For this reason mark them upon
disassembly.
– The fork guiding rods are loaded by means of a spring, so it is recommendable
to slide them upwards from the gearbox forks. In this way the upper spring
remains in the rod and the lower one must be removed from the casing. Then
the gearbox forks can be moved aside.
MAKE SURE THE BUSHINGS DO NOT FALL FROM THE GEARBOX
FORKS.
