	Removing
1	Remove crankshaft (20)	Engine 604, 605, 606	AR03.20-P-4351B
		Engine 611, 612, 613	AR03.20-P-4351C
2	Clean engine parts	After a bearing damage has occurred, remove any swarf which is present in the main oil duct, the connecting rod bores, in the crankshaft and crankcase oil ducts. ↓ Knocking out and inserting a steel ball in the main oil gallery
		Engine 604, 605, 606	AR01.40-P-8498A
		Engines 611, 612, 613 except 612.965/966	AR01.40-P-8498B
		Engine 612.965/966	AR01.40-P-8498GLC
	Checking
3	Check conrod	Perform a visual inspection after bearing damage has occurred. The stem of the connecting rod must not have any cross scores and notches. Replace conrods which have suffered overheating because of bearing damage (blue discoloration).
4	Inspect crankshaft (20)	Perform a visual inspection after bearing damage has occurred. If damage is present ↓ Check crankshaft (20); repair as necessary
5	Mount crankshaft (20) radially	Engines 604, 605, 606	AR03.20-P-4355-01A
		Engines 611, 612, 613 except 612.990	AR03.20-P-4355-01B
		A radial bearing for the main bearing on standard size crankshafts is possible by assigning the color marked bearing shells, see: ↓
		Assign crankshaft bearing shells	AR03.20-P-4360-01HA
6	Mount crankshaft (20) axially	Engines 604, 605, 606	AR03.20-P-4355-02A
		Engines 611, 612, 613 except 612.990	AR03.20-P-4355-02B
7	Install in reverse order
