Removing –  Remove toothed belt → Chapter.

–  Remove the notched belt-crankshaft sprocket. To do this, counter-hold sprocket with special tool -3415-.

–  Unscrew bolts -1 ... 10-. –  Lift off the sealing flange on the belt pulley side. –  Drive out seal with flange removed. Installing   Note Place a clean cloth over the exposed section of the sump. –  Remove sealant residue on cylinder block and on oil sump carefully.   WARNING Wear eye protection.

–  Remove sealant residue from sealing flange with rotating plastic brush or similar. –  Clean sealing surfaces; they must be free of oil and grease.

–  Cut off the tube nozzle on the front marking (diameter of the nozzle approximately. 2 mm).

–  Apply a fine sealant grub (on both sides) on the edge between cylinder block and oil sump -arrows-.

–  Apply sealant bead onto clean surface on sealing flange -arrow- as shown in figure. l  Thickness of the sealant grub: 2 ... 3 mm.   Note Sealant bead must not be wider than 3 mm, otherwise excess sealant could ingress into sump and clog strainer in oil intake pipe.

–  Apply thin sealant bead to lower surface of sealing flange -crosshatched area-.   Note The sealing flange must be installed within 5 minutes after applying sealant. –  Slide the sealing flange carefully onto the engine block pins.   Note Once the seal is installed, use the guide sleeve -T10053/1- to position the sealing flange.

The remaining installation steps are carried out in reverse sequence - note the following points: –  Install toothed belt and adjust the valve timing → Chapter. –  Install crankshaft pulley → Chapter. –  Install poly V-belt → Chapter. –  Install the lock carrier → Rep. gr.50.

–  The torque reaction support must set itself on its rubber stop by means of its self weight, then tighten the nuts -arrows-. Tightening torque → Chapter „Assembly mountings - exploded view“ –  Fit the front bumper cover → Exterior body installation work; Rep. gr.63. –  Check headlight adjustment → Booklet301.
