lubricate the bearing surface with clean engine
lubricating oil.
Caution: Only the upper half of the bearing has
lubrication holes and must be fitted to the cylinder
block.
2 Fit the plain end of the upper half of the bearing
between the crankshaft journal and the side of the
bearing housing which has the recess for the location
tag. Slide the bearing into its housing until the tag on
the bearing is fitted correctly in its recess in the
housing.

with the location tags of both bearings on the same
side (A1).

and renew them if necessary. Lightly lubricate the
setscrew threads with clean engine lubricating oil. Fit
the setscrews and tighten the setscrews gradually
and evenly to 265 Nm (196 lbf ft) 27,0 kgf m.
