PISTON AND CYLINDER
Reverse the above operations to install the piston
and cylinder.
NOTE:
Fit the piston with the mark on its crown facing the
exhaust side.
Apply a molybdenum-oil solution to the piston
bolt and the connecting-rod foot.
Cover the cylinder base with a clean cloth to
prevent the piston-bolt spring ring from falling into
the crankcase. After that, use long-nose pliers to
attach the piston-bolt spring ring.
CAUTION!
Use a new piston-bolt spring ring to prevent it from
breaking if bent.
Apply motor oil to the sliding surface of the piston
and the connecting-rod crank end.
Attach the centering pins (1) and a new seal (2)
to the crankcase.
CAUTION!
Use a new seal, to prevent oil leaks.
Hold the piston rings with their sections properly
positioned, and attach them to the cylinder. Check
to see that the rings remain properly held by the
cylinder skirt.
NOTE:
When fitting the cylinder, tighten the camshaft
driving chain after attaching it. The camshaft driving
chain must not get jammed between its pinion and
the crankcase when the crankshaft is turning.
NOTE:
The crankcase features a moulded bracket for the
lower end of the camshaft driving-chain guide.
Check to see that the guide (3) fits correctly, as
otherwise both the chain and the guide may become
jammed.
