Use a suitable tool to push the upper half of the shell bearing from the side opposite to the location tag.
Carefully rotate the crankshaft to release the bearing from its housing.
Keep the bearing halves in their relevant positions.
Caution: The shell bearings that do not have an oil hole must only be fitted to the cap. If they are fitted to the
cylinder block, the bearing will not receive lubricating oil and this will cause a seizure of crankshaft and
bearings.
Lubricate the main bearings with clean engine oil. Put the bearing (with the oil hole) onto the journal and slide
the plain end around between the journal and the cylinder block until the tag is fitted correctly into the recess.
Fit the bearing into the cap with the tag of the bearing fitted correctly in the recess in the cap.
Fit the bearing cap with the location tags of both bearings on the same side.
After each cap is tightened, ensure that the crankshaft turns freely. If the thrust washers have been removed
and fitted, check the crankshaft end-float, see Operation 5-5.
