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 as guides into the cylinder block flange at two positions.

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

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

t	2…3 mm thick.

Note

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