Offer the cylinder over the pistons as shown in
Fig. C41, pushing the cylinder down to slide the
ring clamps down quickly. The pistons are now
entered in the cylinder bores.

Tighten the cylinder base nuts in sequence.
Tighten the 3/8 in. nuts to a torque setting of 25

ASSEMBLING PRIMARY TRANSMISSION
|
|
|
|
The primary transmission is assembled in the
order:
inner primary chaincase, engine sprocket, clutch
and primary chain, rotor and stator and finally the
outer primary chaincase. The full routine is
detailed below:
|
|
|
|
1
|
Check that the engine sprocket key will pass
freely through the keyway in the sprocket and if
necessary relieve any roughness.
|
|
2
|
Fit the engine sprocket key into the crankshaft.
|
|
3
|
Fit the inner chaincase to crankcase gasket,
holding in position with grease or a non-setting
jointing compound.
|
|
4
|
Check that the plain washer is on the chaincase
support stud (on some units an additional thinner
large diameter washer is used at this point).
|
|
5
|
Ensure that the inner and outer joint faces of
the inner chaincase are clean.
|
|
6
|
Fit the inner chaincase, ensuring that the
gearbox mainshaft seal passes over the mainshaft
without damage and that the chaincase forward end
is fully home.
