Crankcase assembly: crankshaft/connecting rods assembly
Tighten the screws (1) with a torque wrench and angle reading (degree wheel) in accordance with the procedure described
below (observe the same tightening sequence at each step as that of the previous step):
1 first torque each screw to a value of 20 Nm;
2 now carry out a second tightening stage applying a torque of 35 Nm on each screw;
3 now tighten each screw, reading the angle of rotation, to 70 Nm, checking that the final angle is between 55° and
75°.
Important
If the final angle is less than 55° or greater than 75°, repeat the procedure using two new screws.
Refitting the crankshaft/connecting rod assembly
Install the connecting rod assembly (6) and (2) in the crankcase, carry out the shimming and crankcase half reassembly
procedure as described in Sect. 9 - 9.2,
Important
Make sure that the connecting rods (2) are correctly positioned in the cylinders. Incorrect positioning of the connecting
rods at this stage will inevitably lead to the need to re-open the crankcase halves.
