  Note
t  Note the expiry date of the Silicone sealant -D 176 404 A2-.
t  Install sump within 5 minutes of applying silicone sealant -D 176 404 A2-.
   
–  Cut off tube nozzle at forward marking (Ø of nozzle approx. 3 mm).
–  Apply silicone sealant -D 176 404 A2-, as shown, to clean sump sealing surface. Sealant bead must be:
t  2…3 mm thick.
t  Run bead along inner side of bolt holes -arrows-.
  Note
The sealant bead must not be thicker, otherwise excess sealing compound will enter the oil sump and may block the oil suction line strainer.

–  Take extra care when applying sealing compound bead at points marked by -arrows-. (The figure shows the position of the sealant bead on the cylinder block.)
–  Put sump in position immediately and tighten bolts as follows:
1 - Tighten all sump/cylinder block bolts only very lightly and diagonally.
2 - Tighten sump/gearbox bolts lightly.
3 - Further tighten all sump/cylinder block bolts lightly using diagonal sequence.
4 - Tighten sump/gearbox bolts to 25 Nm.
5 - Tighten all bolts between sump and cylinder block diagonally to 15 Nm.
  Note
t  When installing sump with engine out of the vehicle, ensure that sump is flush with cylinder block at flywheel end.
t  Allow Silicone sealant -D 176 404 A2- dry for approx. 30 minutes after installing sump. Only then fill with engine oil.
Further assembly is basically the reverse of the dismantling sequence.
