-- Clean any oil or grease off the sealing surfaces.

-- Apply sealant beads -arrows- to the clean sealing surfaces on the guide frame as shown in the illustration.

• The groove of sealing surface must be completely filled with sealant.
• The sealant beads must be 1.5 to 2.0 mm above the sealing surface.

-- Position seals -1 and 2-.

-- Check if alignment bushings -3 through 6- are inserted at the locations in the guide frame as shown in the illustration.

-- Insert the long bolts in the inner row of the guide frame.

-- Tighten the bolts in steps in the sequence shown:

Step	Bolts	Tightening Specification/Additional Turn
1.	-1 to 16-	50 Nm
2.	-1 to 16-	Turn an additional 90°.
3.	-17 to 31-	20 Nm
4.	-17 to 31-	Turn an additional 90°.

• Bearing shells with the correct thickness are allocated to the cylinder block in the factory. Colored dots on sides of bearing shells serve for identifying bearing shell thickness.
• Allocation of bearing shells to cylinder block is marked by a letter on the respective bearing on guide frame

Letter on Guide Frame		Color of Bearing
R	=	Red
G	=	Yellow
B	=	Blue
S	=	Black

• Bearing shells with the correct thickness are allocated to the guide frame in the factory. Colored dots on sides of bearing shells serve for identifying bearing shell thickness.
• The allocation of the bearing shells for the guide frame is identified by a series of letters on the crankshaft flywheel flange. The first letter of the row of letters represents bearing "1", the second letter is for bearing "2", etc.
