Cylinder and piston disassembly
- Remove the timing chain.
- Unloose the fixing screw and remove the spacer and
the tightener pad.
N.B.: It is recommendable to mark the chain in order to
refit it in the original direction of rotation.
- Remove the cylinder and relevant gasket, and the
centering dowel.
N.B.: The second centering is made possible thanks to
a pin fitted in the cylinder.
- To avoid damaging the piston, hold it
while disassembling the cylinder.
Warning
- Remove the 2 stop rings of the piston gudgeon pin
through the specific openings.
- Remove the gudgeon pin and the piston.
N.B.: Close the cylinder housing opening on the crank-
case with paper or a cloth, to prevent one of the two stop
rings from falling inside.
- Remove the compression rings and the scraper ring.
- Mark the compression rings assembly
position to avoid inverting them if they are re-used.
N.B.: Take care not to damage the rings during the
disassembly procedure.
