• The description only applies when installed  .
• If the oil guide housing is removed when the transmission is disconnected, the oil guide housing must be aligned with the aid of a dial gauge   .
• To remove the oil guide housing, it is not necessary to remove the timing case cover. If the timing case cover is removed while carrying out work later, the oil guide housing must also be removed  .

Information 

The tightening specifications for the basic engine are stored centrally (→ 1001IN TIGHTENING TORQUES, TIGHTENING SEQUENCES, ASSEMBLY OVERVIEWS ).

Tightening torques and assembly instructions for other assemblies (e.g. chassis, electrics, transmission or body) or for peripheral engine equipment can be found in the corresponding documents.
