Removing –  Remove the notched belt → Chapter. –  Remove crankshaft notched belt pulley. To do this lock notched belt pulley with retention tool -T20018B-. –  Separate the sprocket from the timing belt-crankshaft by immobilising it with the counterhold -T20018B-. –  Remove the oil sump → Chapter.

–  Unscrew the bolts -1 ... 6- that fasten the front sealing flange. –  Remove sealing flange. If necessary, release by gently tapping with a rubber mallet. –  Drive out seal with flange removed. Fitting Installation is carried out in reverse order, noting the following: –  Clean sealing surface; must be free of oil and grease. –  Remove sealant residue on cylinder block with a flat scraper.   WARNING Wear protective goggles.

–  Using a rotating plastic brush, remove any sealant residue from the sealing flange.   Note t  Observe use-by date of sealant. t  Once the silicone sealant has been applied, fit the sealing flange within 5 minutes.

–  Cut off tube nozzle at upper marking (nozzle diameter approx. 3 mm). –  Apply the silicone sealant as shown to the clean sump sealing surface. t  Thickness of sealant bead -arrows-: 2 ... 3 mm.   Note The sealing bead must not be thicker, otherwise excessive sealing compound will enter the sump and may block the oil suction pipe filter.

–  Apply the silicone sealant bead -arrow- to the clean sealing surface of the sealing flange, see figure. –  Fit sealing flange immediately and tighten all bolts slightly.   Note Use the adaptor -T20081B/4- to fit sealing flange with the oil seal already installed. –  Tighten the attachment bolts of the seal flange diagonally. –  Fit the oil sump → Chapter.   Note After fitting the oil sump, leave the sealant to dry for approx. 30 minutes. After this time, the engine oil may be filled.

–  Fit the timing belt-crankshaft sprocket, immobilising it with the counterhold -T20018B-. –  Tighten the new central bolt.   Note There must be no traces of oil or grease on the thread or collar. –  Fit the timing belt → Chapter. –  Fit the vibration damper → Chapter. –  Fit the Poly-V belt → Chapter.
