Removing –  Take off toothed belt. → Chapter. –  Loosen bolt for crankshaft sprocket using counterhold tool -3415-.

–  Remove bolts -1 ... 10- and carefully release sealing flange from bonded joint. –  Drive out oil seal with sealing flange removed. Installing Reassembly is carried out in the reverse order; note the following: l  Tightening torque → Chapter „Sealing flange on the pulley side Assembly overview“   Caution Make sure sealant residue does not enter lubrication system. 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. –  Use rotating plastic brush to remove sealant residue on sealing flange. –  Clean sealing surfaces; they must be free of oil and grease.   Note t  Note the use-by date of the sealant. t  The sealing flange must be installed within 5 minutes of applying silicone sealant.
