Additional tightening specifications






Mounting, S-tronic transmission to engine










Installation is in reverse order of removal, note the following:

• The engine/transmission subassembly is attached to the engine bracket (T10012).

• Replace bolts which have been tightened to an additional torque.

• Replace self-locking nuts and bolts as well as sealing rings, seals and O-rings.

• The hose connections as well as the air guide pipes and hoses must be free of oil and grease before installing.

• Secure all hose connections with hose clamps appropriate for the model. Refer to the electronic parts catalog ETKA.

• In order to be able to securely mount the air guide hoses on their connectors, spray the bolts on the previously used clamps with a rust remover.

• During installation, all cable ties must be installed at the same location.

- Make sure the intermediate plate is engaged on the sealing flange and slide onto the guide sleeves - arrows -.





- If the alignment sleeves - A - for centering the engine and transmission are missing inside the cylinder block, then install the sleeves.

- If a needle bearing is installed in crankshaft, remove needle bearing. Refer to => [ Needle Bearing on Crankshaft ] Needle Bearing on Crankshaft.

- Lightly lubricate transmission input shaft splines with clutch disc connection lubricating grease. Refer to the electronic parts catalog ETKA.

- Check clutch drive plate centering.

- If the alignment sleeves - A - for centering the engine and transmission are missing inside the cylinder block, then install the sleeves.





- If no needle bearing is installed in crankshaft, install needle bearing. Refer to => [ Needle Bearing on Crankshaft ] Needle Bearing on Crankshaft.

- Tighten the transmission to the engine.

- Guide the engine/transmission subassembly into the body.

- Install the bolts - arrows - for the subframe mount on the engine side first by hand all the way.





- Install the bolts - arrows - for the subframe mount on the transmission side first by hand all the way.
