Step D)
Install the connecting rod cap respecting numbering, and fasten the relevant bolts (lubricating
both the head and the threaded stem with the same oil used for the crankcase) proceeding in
three different steps,see fig. 7:
Torque (Nm) specification:
1. Approaching torque 6 - 8 Nm
2. Pre-fasting torque 25 - 28 Nm
3. Fastening torque 38 Nm

Disassembly / Assembly of the crankshaft without replacing the bearings
After removing the side covers, check the rollers and their races for ware; if all parts are in good
conditions, accurately clean the components with a suitable degreaser and grease them again evenly
using the same oil used in the crankcase.
The same shims can be used again, being careful to fit them under the cover on the sight glass side.
After installing the complete unit (sight glass side shaft + engine side flange), check that the
shaft’s rolling torque - with the connecting rods free – is at least 4 Nm, Max 7 Nm.
Position the two side covers on the crankcase, initially use N°3 screws M6x40 as shown in fig. 6, and
then the fastening screws. The shaft’s rolling torque (with connecting rods coupled) must not exceed
8 Nm.
