D) Install the connecting rod cap taking care the numbers
match and tighten the relevant bolts in 3 different
stages:
1. Approach torque 6 - 8 Nm
2. Presetting torque 25-28 Nm
3. Tightening torque 38 Nm
Note: The screws must be greased on the thread and
under the head.
D) Fit the back cover putting the dipstick hole upward.
11.1.3 Disassembling / Reassembling of the bearings
and shims
The type of bearings (conical roller) ensures there is no
end float on the crankshaft; the shims must be
determined to reach that purpose. To disassemble,
reassemble and if required replace them, it is absolutely
necessary to do as indicated below.
11.1.4 Dissassembling / Reassembling of the crank-
shaft without replacing the roller bearings
After removing the side covers, as indicated on point
11.11.1, check the rollers and races for wear; if they are
in good shape, accurately clean the components with
suitable degreaser and grease them again evenly with
oil (same as the pump oil). The same shims can be used
again taking care to fit them under the sight glass side
cover. After installing the complete unit (glass sight side
flange and crankshaft and motor side flange), check that
the rolling couple - with connecting rods free - is at least
3 Nm, mas 6 Nm. To position the 2 side covers on the
crankcase use 3 screws M6 x 40 first, and then the
original screws to fix them.
The rolling couple of the crankshaft (with connecting
rods coupled) must not exceed 8 Nm.
11.1.5 Disassembling / Reassembling of the crank-
shaft with replacement of the bearings
After disassembling the side covers, as indicated on point
11.11.1, remove the outer ring nut of the bearings
from their covers and the inner ring nut, together with
the remaining part of the bearing, from the 2 shaft ends
by means of a standard pin extractor or similar tool. See
