DISASSEMBLY/REASSEMBLY
Re-coil starting
Operation:
When pulling handle 10, thanks to the action of friction spring 12,
teeth 4 protrude from cap 3. After starting these teeth go back to the
initial position because the cap rotates. Rope 9 is re-wound around
pulley 6 by means of spring 7.
Components:
1 Retainer 7 Spring
2 Washer 8 Guard
3 Cap 9 Rope
4 Flyweights 10 Handle
5 Spring 11 Rope guide
6 Pulley 12 Spring
Note: there are two kinds of guards 8, one for engines with an rpm
above 2000 and one with fewer cooling channels for engines
with a lower rpm
On reassembly, tighten the screws to 10Nm.
Shroud
The shroud and the metal sheeting outside the cylinder are made of
special material (ANTIPHON) which absorbs noise, thus reducing
total engine sound pressure levels.
When refitting tighten shroud screws to 10 Nm.
During the demounting phases, pay particular attention to
prevent the flywheel from dropping as this could seriously
injure the operator.
Wear protective goggles when removing the flywheel ring.
Flywheel
Unscrew bolt 1 in a clockwise direction.
Remove the flywheel with a puller.
Make sure that the tapered surface that couples to the drive shaft is
not damaged.
To remove the starter rim, it is advisable to cut it into several parts
with a hacksaw and to then use a chisel. To replace, slowly heat for
15-20 minutes to a temperature of 300°C max.
Fit the rim into the flywheel housing. make sure that it rests evenly
against the support of the housing itself.
Allow it to slowly cool.
When refitting tighten bolt 1 to 150 Nm.
See pages 34 and 35 for injection timing reference marks.
