removing –  Remove Poly V-belt → Chapter. –  Remove the notched belt → Chapter. –  Turn crankshaft back slightly.

–  Remove the notched belt-crankshaft sprocket. Immobilise the notched belt sprocket using the counterhold -3415-. –  Drain the engine oil. –  Remove sump → Chapter. –  Loosen the sealing flange, pulley side. –  Remove sealing flange. If necessary, loosen by giving light taps with a rubber hammer. –  Remove sealant residue on cylinder block with a flat scraper. –  Cover the seal with a clean cloth.

–  Remove sealant remaining on sealing flange with rotating plastic brush (wear eye protection). –  Clean sealing surfaces. The sealing surfaces must be free of oil and grease. Fitting

–  Cut nozzle off tube at front marking (Ø nozzle diameter approx. 3 mm). –  A layer of adhesive sealing material of approximately 2-3 mm as shown in -arrow- on the clean, apply sealed surface of the sealing flange.   Note t  Before applying the strip of sealant, clean the seal with a clean cloth. t  The strip of sealant must not be thicker than 2 - 3 mm, otherwise the excess sealant may enter the oil sump and obstruct the strainer in the oil intake pipe. t  Observe use-by date of sealant. t  The sealing flange must be installed within 5 minutes of applying silicone sealant. t  Once the seal is installed, use the guide sleeve -T10053/1- to position the sealing flange. t  After fitting sump, allow the sealant to dry for approx. 30 minutes. Only then should the engine be refilled with oil.

Tightening torque: 15 Nm. –  Clean off any excess sealant. –  Fit the oil sump → Chapter. –  If necessary, fit seal → Chapter   Note t  There should be no oil on the contact surface between the notched pulley, the diamond-coated washer and the crankshaft. t  Replace the centre bolt. t  The thread and collar must be free of oil and grease.

–  Fit the notched pulley -2- with a diamond-coated washer -3- and tighten the bolt by hand -1-.

–  Immobilise the notched belt sprocket using the counterhold -3415-. –  Tighten the new centre bolt to a torque of 90 Nm + 1/4 turn (90°) (the retightening can be done in several stages). Continue installation following reverse order for removing. Installing toothed belt and adjusting valve timing → Chapter.
