- Take out the spacer flange
mounting screws. Remove
the spacer flange and
gasket from the cylinder.
- Inspect the cylinder and replace
it if necessary.
Note: If a new cylinder has to be
installed, always fit the matching
piston. Replacement cylinders
are only supplied complete with
piston for this reason.
- Remove the cylinder gasket.
Important: Before removing the
piston, decide whether or not
the crankshaft has to be
removed as well. To remove the
starter cup, the clutch and the
flywheel, see 7.7, 4.1 and 6.1.5,
block the crankshaft by sliding
the wooden assembly block
between the piston and
crankcase.
- Use a scriber or similar tool to
ease the hookless snap rings
out of the grooves in the piston
bosses.
- Now use the assembly drift to
push the piston pin out of the
piston. If the piston is stuck,
tap the end of the drift lightly
with a hammer if necessary.
Important: Hold the piston
steady during this process to
ensure that no jolts are
transmitted to the connecting
rod. Remove piston and take
the needle cage out of the
connecting rod.
- Inspect piston rings and
replace if necessary, see 5.3.
