Installing

Note

t	Observe expiry date of sealing compound.

t	The sump must be installed within 5 minutes of 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 front marking (Ø of nozzle approx. 3 mm).

–	Apply silicone sealant to clean sealing surface of sump as shown. Sealant 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, otherwise excessive sealing compound will enter the sump and may block the oil suction pipe strainer.

–	Immediately position sump and tighten all sump bolts slightly.

–	Tighten sump bolts to 13 Nm.

Note

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