Installing

Note

t	Note the use-by date of the sealant.

t	The sump must be installed within 5 minutes after applying the silicone sealant.

t	To help when fitting the oil sump, threaded pins M6 may be inserted in two points in the cylinder block flange.

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

–	Apply the silicone-based sealant to the clean contact surface of the oil sump, proceeding as shown. The strip of sealant must:

t	2...3 mm thick.

t	Apply along the inner edge of the bolt holes -arrows-.

Note

The sealant bead must not be thicker. Otherwise the excess sealant may enter the oil sump, and obstruct the strainer in the oil intake pipe.

–	Install sump immediately and tighten all sump bolts lightly.

–	Tighten oil sump bolts to 9 Nm.

Note

Starting can be carried out 30 minutes after applying the sealant to the oil sump. Only then should the engine be refilled with oil.
