16 - Cylinder block
Centering washer for drive plate on automatic transmission 09L
Note:
^ On vehicles with automatic transmission, the drive plate is bolted to the crankshaft with a centering washer - arrow -.
Sealant application for guide frame, position of alignment bushings
- Clean sealing surfaces, they must be free of oil and grease on top and bottom.
- Apply sealant beads - arrows - on clean sealing surfaces of guide frame as shown in illustration.
^ The groove of sealing surface must be completely filled with sealant.
^ Sealant beads must be 1.5 to 2.0 mm above the sealing surface.
- Install seals - 1 to 3 -.
Note:
^ Depending on the version, the seals -2- and -3- are connected by a rib.
- Check whether alignment bushings - 4 through 7 - are inserted at locations in guide frame as shown in the illustration.
Installing guide frame
- Replace guide frame bolts - 1 through 16 -.
- Insert long bolts in the inner row of the guide frame.
- Tighten bolts - 1 through 31 - in 3 stages as follows:
- Tighten bolts to 50 Nm in sequence - 1 to 16 -.
- Tighten bolts an additional 90 degree in sequence - 1 to 16 -.
- Tighten bolts for guide frame sealing surfaces on the cylinder block to 23 Nm in sequence - 17 to 31 -.
Allocation of crankshaft bearing shells for cylinder block
^ 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
Through engine no. AUK 028 000 or BKH 033 000:
On engines through no. AUK 028 000 or BKH 033 000 another allocation of letters on guide frame to bearing shell color applies to bearing 1 (front).
From engine no. AUK 028 001 or BKH 033 001:
Allocation of crankshaft bearing shells for guide frame
^ 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.
^ Allocation of bearing shells to guide frame is marked on flywheel flange of crankshaft by a row of letters. The first letter of the row of letters represents bearing "1", the second letter is for bearing "2", etc.
