-
Remove the gear fitted on the camshaft: unscrew the
screw (1) and remove the spacer (2); extract the gear (3)
from the camshaft.
During disassembly, the components (5) and (6) are
fastened by the screws (7) on the gear (3). If
necessary, separate the various parts and replace the
worn ones.
Figure 2
Check the protrusion of the pistons (6) from the crankcase
and note it down.
Set the cylinder assembly upright. Extract the pistons as
follows:
- Loosen the nuts (1) of the bolts fixing the connecting rod
caps to the connecting rods.
- Turn the crankshaft until the piston is exactly at the TDC;
in any other position it would not be possible to extract
the piston because the connecting would interfere with
the cylinder liner.
- Remove the connecting rod cap (2) and extract the
piston from the cylinder liner.
Set the crankcase horizontally. Remove the top (4) and side
(3) bolts fixing the main bearing caps to the crankcase and ex-
tract them.
On the central main bearing housings (5) and on the
cap there are the thrust half—rings for adjusting the
crankshaft end float.
