Rear and forward main bearing caps
Important
Before the nal tightening, check the coplanarity of the two
levels with a ground bar
On remounting the rear main bearing cap 1 replace the lateral
rubber gaskets 2, keeping in mind that projections A and B of
the support must be 0,5÷1,0 mm; cut off any exceeding portions.
Do the same with the front bearing cap.
Before reintroducing the bearings in the crankcase, place
between their surfaces two plates C and D - 0.1 mm thick -
se.no.7107-1460-053.
Tighten the screws at a torque of 60 Nm.
Note: It is advisable to apply a few drops of silicon sealant on
the surface of the gasket slot 2.
Central main bearing caps
The central support caps are marked with locations that can be
numbers as in the diagram or dots.
The same locations are given on the crankcase.
Couple the caps with the same references and on the same
side. In any case locate the bearing’s two centring notches that
are to be found on the same side.
Tighten the screws simultaneously at a torque of 60 Nm.
Check the clearances between the bearings and the journal
Use the ”Perfect Circle Plastigage” type calibrated wire A and
put it at the centre of the bearing with a bit of grease.
Tighten the screws at a torque of 60 Nm.
Find out the clearance value checking the wire’s compression
with the appropriate graduated scale supplied in the same pack
and available on the market.
For clearance values between the journals, connecting rod
pin and the relevant bearings see page 74.
