Assembly
Before the piston and cylinder and fitted

as instructed in the Workshop Manual.
Check that the rubber intake manifold
between the cylinder and distance
piece has not cracked or shows signs
of other damage that can cause leaks.
Clean any sealant or grease from the
crankcase.
Fit the piston on the connecting rod so
that the arrow on top of the piston
points towards the exhaust port. See
the instructions in the Workshop
Manual.
Clean the old sealant and grease from
the contact surfaces on the base of the
cylinder.
Apply a narrow string (1 – 1.5 mm) of
sealant No. 503 26 70-01 to the contact
surface.
NOTE!
The sealant does not need to be
applied to the bearing's contact surface.
Lubricate the piston with a few drops of
oil and carefully slide the cylinder over
the piston.
NOTE!
Do not turn the cylinder as the piston
ring can easily break.
Tighten the 4 bolts crosswise.

order as stated for dismantling.
