side B (fig. 7).
During the assembly operations, make sure that the bearing
holes match the oil ducts by making reference marks with a felt-
tip pen.
Make sure that the reference mark on the bearing edge points
towards:
- the casing interior
- the outer part of the timing system cover.
WARNING
Proceed with the following inspections after assembly:
Cover on timing system side
The main bearing must project 1.7 to 2 mm in relation to
the bearing surface of the bull ring (inner side of cover).
Engine casing
The main bearing must be flush with the bearing surface
of the shimming ring (inner side of casing).
