9	Remove connecting rod bearing cap (16)	While turning the crankshaft ensure that the connecting rods (11) do not get jammed. To do this, mark connecting rod (11) and connecting rod bearing cap (16) on one side relative to each other.
10	Unscrew the crankshaft bearing cap bolts	Pay attention to the bolt release pattern: ↓ Tightening diagram of crankshaft bearing caps	AR03.20-P-4351-02BV
11	Remove the crankshaft bearing caps (4, 10) and fitted bearing (5)	Before removing, mark the crankshaft bearing caps (4, 10) and fitted bearing (5). Carefully lever out crankshaft bearing caps (10) and (5).
12	Take crankshaft (1) out of the crankcase
13	Take crankshaft bearing shells with oil hole and oil groove (crankcase) (2) and thrust washers (6) out of the crankcase
	Installing
14	Insert crankshaft (1)	Oil the crankshaft journals and crankshaft bearing shells.
		If a new crankshaft is being installed	AR03.20-P-4341-01CV
		If crankshaft is being repaired	AR03.20-P-4341-01CVA
15	Tighten the crankshaft bearing caps	The crankshaft bearing cap bolts M8x75 and M10x90 must always be replaced otherwise there is a risk of cranks and fracture.	AR03.20-P-4351-02BV
		Tighten all bolts at the same time as specified in the tightening diagram.

		Side crankshaft bearing cap bolt	*BA03.20-P-1002-01D
		Crankshaft bearing cap bolt	*BA03.20-P-1003-01D
16	Check axial play of crankshaft	If a new crankshaft is being installed	AR03.20-P-4291-03AV
17	Inspect connecting rod bolts (12)	Test data: ↓ Thread and shank length	AR03.10-P-6111-01BV  *BE03.10-P-1001-03A
18	Install connecting rod bearings and fit connecting rod bearing cap (16)	The connecting rod bearing shell (13) with the drilling (arrowed) must be installed in the connecting rod (11), otherwise the connecting rod bearings will not be lubricated. The anti-twist lock (14) on the connecting rod bearing shell (13) must be located in the grooves (15) of the connecting rods(11)and of the connecting rod bearing cap (16). connecting rod (11) and connecting rod bearing cap (16) are cracked They must not be installed on the wrong side, as dimensional accuracy would be lost.
