Installing

Note

t	Observe expiry date of sealing compound.

t	The sump must be installed within 5 minutes after applying silicone sealing compound.

t	Sump can be positioned more easily and with greater security if M6 studs are inserted into the cylinder block flange at two positions as guides.

–	Cut off tube nozzle at forward marking (nozzle Ø approx. 3 mm).

–	Apply silicone sealing compound, as shown, to clean sealing surface on sump. Sealing compound bead must be:

t	2...3 mm thick.

t	Run bead along inner side of bolt holes -arrows-.

Note

The sealing compound bead must not be thicker, or excessive sealing compound will enter the sump and may block the oil suction pipe strainer.

–	Tighten sump bolts to 13 Nm.

Note

Let sealing compound dry for approx. 30 minutes after installing sump. Only then fill with engine oil.
