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
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.
Dissassembling / Reassembling of the cranshaft
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 (sight glass side
flange and crankshaft and motor side flange), check that
the rolling couple - with connecting rods free - is at least
4 Nm, max 7 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.
C) Before reassembling the side covers, check the seal
lips for wear. If they need replacing, fit the new ring
following the indications in Fig. 12.
Note: Should the shaft show diameter wear in the seal
position, it is possible to avoid grinding it by fitting the
seal further as indicated in Fig. 12. Before installing the
cover, (sight glass side) check the shim rings have been
placed. To help the covers fit on the crankcase, you can
use 3 screws M6 x 40, and then finish screwing them
with the original bolts (M16 x 18).
Note: The screws must be greased on the thread and
under the head
E) Fit the back cover putting the dipstick hole upward.
