Install O-ring (34) in its seat (35) in the crankcase half. Fit the hose (11) in the crankcase half, by inserting the end
(36) fully in the O-ring.
Align the hole (37) of the hose with the threaded hole (38) in the crankcase half.
Position bushing under crankcase half jet (11), on generator side.
Apply threadlocker to the screw (10) and start it in the threaded hole (38).
Tighten the screw to a torque of 8 Nm (Min. 7 Nm - Max. 9 Nm).
Install the timing layshaft (8) in the roller bearing (19) of the clutch-side crankcase half.
To avoid damaging the sealing ring (24) on the timing layshaft, protect the threaded end of the shaft with the special protective

the gearbox shaft bearings are fitted into the correct bearings and have not been left on the shafts.
Fit the shimmed crankshaft (6) into the clutch-side crankcase half bearing, positioning the connecting rods (45) in correspondence
with the relative cylinder barrel seats.
Check that the two centring bushes (30) are correctly fitted.
Grease the O-ring (9) to hold it in position and install it on the oil way connecting the two crankcase halves.
Make sure that the connecting rods (45) are correctly positioned in the respective cylinder seats.
Incorrect positioning of the connecting rods at this stage will inevitably lead to the need to re-open the crankcase half.
