Removing . l  Engine installed. –  Remove toothed belt → Chapter. –  Turn crankshaft back slightly.

–  Remove crankshaft sprocket. For this purpose, lock using the retention tool -3415-.

–  Remove bolts -1 ... 10-. –  Remove sealing flange. If necessary, loosen by giving light taps with a rubber hammer. –  Drive out seal with flange removed. Installing . Installation is carried out in the reverse order of removing, when doing this note the following.   Note Lie a cloth over the open part of the oil sump. –  Remove sealant residue on cylinder block and on oil sump carefully.   WARNING Wear eye protection.

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

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

–  Apply a thin length of silicon sealant to each one of the edges between the engine block and the oil sump -arrows-..

–  Apply the silicone sealant bead -arrow- to the clean sealing surface of the sealing flange, see figure. l  Thickness of sealant bead -arrows-: 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.

–  Coat the lower sealing surface at the sealing flange lightly with silicone sealant -striped area-.   Note The sealing flange should be fitted within 5 minutes following the application of the silicon sealing paste. –  Slide the sealing flange carefully on the engine block pins.

–  Tighten bolts in the following sequence: –  Tighten bolts -1 … 6-. –  Tighten bolts -7 … 10-. –  Fit crankshaft oil seal (on the pulley side) → Chapter. l  There should be no oil on the contact surface between the notched belt sprocket and the crankshaft l  Do not lubricate the geared teeth of the crankshaft.

–  Immobilise the sprocket using the retention tool -3415- –  Tighten the new screw to 120 Nm + 1/4 turns (90°) using a spanner. Turning further can be done in several stages. Perform further installation in reverse order, paying attention to the following: –  Install notched belt (adjusting valve timing) → Anchor. –  Install vibration damper → Chapter. –  Install poly V-belt → Chapter.
