Cylinder and piston

Assembly

Clean the crankcase.
Assemble the piston on the connecting
rod.
NOTE!
Place a rag in the crankcase opening to prevent the circlip from falling
into the crankcase in case it should fly out. Check that the circlips are
correctly fitted into the grooves by turning the clips with flat nosed pliers.
Assemble the cylinder.
NOTE!
Do not turn the cylinder, as the piston rings can easily be broken.
Check that the cylinder is fitted so the crankshaft bearing lies in an
unchanged position. Otherwise there is a risk that leakage can occur
between the bearing and cylinder.
Tighten the 4 screws diagonally crosswise.
Assemble the remaining parts in the
reverse order as set out for dismantling.
Assembly
Clean the crankcase.
Fit the piston on the connecting rod so
that the arrow on the piston points
towards the exhaust port. Lubricate the
gudgeon pin's needle bearing with a
few drops of engine oil.
Direct the arrow on the top of the piston
towards the exhaust port. Press in the
gudgeon pin and fit the circlips.
Check that both gasket halves are
undamaged and are positioned
correctly on the crankcase (also see
chapter. 7).
Lubricate the piston using a few drops
of oil and carefully slide the cylinder
over the piston.
Assemble the remaining parts in the
reverse order as set out for dismantling.
