Installing sump
  Note
t  Observe expiry date of sealing compound.
t  The sump must be installed immediately and tightened after applying silicone sealing compound.
–  Clean sealing surfaces. They must be free of oil and grease.
  N17-0012
–  Cut off tube nozzle at forward marking (approx. 3 mm nozzle Ø).
–  Apply silicone sealing compound, as shown, onto clean sealing surface on sump. Sealant bead must be:
t  2...3 mm thick.
t  Run bead along inner side of bolt holes -arrows-.
  Note
t  The sealant bead must not be thicker, otherwise excess sealant will enter the oil sump and may block the oil suction line strainer.
t  If gearbox is removed, sump must align smoothly with cylinder block.
t  If gearbox is installed, sump must rest against gearbox.
t  Let sealing compound dry for approx. 30 minutes after installing oil sump. Only then fill with engine oil.
–  Put sump in position immediately and tighten bolts as follows:
1 - Tighten all bolts between sump and cylinder block only very lightly and diagonally.
2 - Lightly tighten bolts securing sump to gearbox.
3 - Tighten all bolts securing sump to cylinder block slightly further in diagonal sequence.
4 - Tighten bolts securing sump to gearbox to 40 Nm.
5 - Tighten all bolts securing sump to cylinder block in diagonal sequence 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  Let sealing compound dry for approx. 30 minutes after installing oil sump. Only then fill with engine oil.
Further assembly is basically the reverse of the dismantling procedure.
