DISASSEMBLING THE ENGINE
CYLINDER
Remove the rubber tube that connects the
cylinder to the water pump after having loo-
sened the clamp; turn the motor shaft until
the piston lies in the top dead centre and
loosen the four bolts A that fasten the cylin-
der to the base unit. Then gently remove the
cylinder by pulling it upwards.
Note: Should the cylinder be stuck to the
base unit, gently strike the cylinder in va-
rious points with a rubber mallet.
PISTON
Place a clean cloth in the area below the
piston, between the two casings, in order to
prevent any foreign objects or solid residues
from falling into the base unit. Then use a
suitable tool to remove the piston pin lock
ring A. Working from the other side, unth-
read piston pin B as much as is needed to
release the piston assembly from the con-
necting rod. Remove the bearings assembly
C from the connecting rod.
