To Dismantle The Gearbox And Crankshaft Mechanism
To separate the crankcase halves, dismantle the gearbox and crankshaft
assembly are very exacting jobs which should be done under the supervision of an
experienced motorcyclist, or entrusted to a service repair shop; this is preferable as
the workshops are equipped with special tools supplied by the manufacturers. The
method of dismantling and assembling described here is that with special tools
employed.
The crankcase can only be dismantled after the engine has been removed
from the body work. If repairs or replacement of parts are to be done on the RH
crankcase half, the crankcase will be dismantled but the LH half left as it is.
Before dismantling the crankcase, the RH engine side cover has already been
removed and as described in the respective paragraph, the dynastarter has now to
be taken out. Remove on the LH side of the engine the gear change pedal, the kick
starter pedal / model 501 /, the extension / model 502 /. Unscrew the oil draining plug
And drain the oil into a suitable container. Remove the LH side cover; dismantle the
clutch and primary drive as described in the respective paragraph. Slacken the screw
and remove the speedometer drive in the LH crankcase. Take off the carburettor and
its gasket. Remove the clutch operating bracket, the clutch operating rod; pull off the
gearbox sprocket, and the gear change operating cam. Further remove the cylinder
head and the cylinder barrel and the
base gasket. Slacken all the RH
crankcase half securing screws and
expel the crankcase dowels using
drift S-2. Pull the RH crankcase half
off the crankshaft assembly with the
universal puller S-37 Fig. 17
