Refitting ( Removing

) Visually inspect the condition of the main and big end bearing shells and, if necessary, replace them.Check that the thickness of the main journal half-bearings is within the recommended values; if this is not the case, replace them. if this is not the case, replace them.

	Measurement		Value
-	Half-bearing thickness (mm)	Category B	1.836 ÷ 1.844
Category C	1.843 ÷ 1.849
Class A	1.831 ÷ 1.837

Check that the thickness of the connecting rod half-bearings is within the recommended values; if this is not the case, replace them. if this is not the case, replace them.

	Measurement		Value
-	Thickness (mm)	Category B	1.530 - 1.534
Category C	1.533 - 1.537
Class A	1.527 - 1.531

Fit the big end bearing shells.Fit the main bearing shells.Fit the crankshaft on the cylinder block/crankcase.Fit the thrust washers on the 3rd main bearing.Fit the main journal caps complete with half-bearings.

The bearing caps are numbered progressively (from zero to four starting from the front of the engine) which defines their fitting position.
