Removing –  Remove centre noise insulation -fasteners 1 ... 3-.

–  Remove noise insulation (right-side) -fasteners 1 ... 3-.

–  Remove bolts -1- and -2-. –  Remove air pipe (right-side) by lifting retaining clips -arrows- slightly.

–  Unplug electrical connector -arrow- at oil level/oil temperature sender -G266-. –  Drain off engine oil.

–  Unscrew sump/gearbox bolts -arrows-. –  Slacken bolts -1 ... 20- in diagonal sequence and remove.   Note

t  The two rear sump bolts -1- and -2- are accessible via the recess -arrow- on the flywheel -3- (turn the flywheel as required). t  The bolts can be unscrewed using Allen key (long reach) -T10058-. –  Take off sump: if necessary loosen it by striking lightly with a rubber hammer.

Installing Installation is carried out in the reverse order; note the following:   Note Renew seal. –  Remove sealant residue from sump and cylinder block with rotating plastic brush or similar.   WARNING Wear safety goggles. –  Clean sealing surfaces; they must be free of oil and grease.

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

–  Apply bead of sealant onto the clean sealing surface of the sump as shown in the illustration. l  Thickness of sealant bead: 2 ... 3 mm   Note t  Sealant bead must not be wider than 3 mm, otherwise excess sealant could ingress into sump and clog strainer in oil intake pipe. t  Take particular care when applying sealant bead in area of sealing flange (flywheel end) -arrows-. t  The sump must be installed within 5 minutes after applying the silicone sealant.

–  Immediately install sump and tighten bolts in the following sequence: 1.  Tighten bolts -1 ... 20- securing sump to cylinder block in diagonal sequence initially to 5 Nm. 2.  Tighten sump/gearbox bolts -arrows- to 45 Nm. 3.  Tighten bolts -1 ... 20- in diagonal sequence to 15 Nm.   Note t  When installing sump with engine removed from vehicle, ensure that sump is positioned flush with cylinder block at flywheel end. t  After fitting sump assembly, the sealant must dry for approx. 30 minutes. Then (and only then) fill the engine with engine oil. –  Install air pipes/hoses with plug-in connectors → Chapter. –  Fill up with engine oil and check oil level → Chapter. Tightening torques
