Removing seal: –  Remove poly V-belt → Chapter. –  Remove toothed belt:    Vehicles with split toothed belt guard → Chapter.    Vehicles without split toothed belt guard → Chapter.

–  Remove crankshaft toothed belt pulley. To do this, lock toothed belt pulley using counterhold -3415-.

–  To guide seal extractor, screw centre bolt into crankshaft to stop by hand. –  Unscrew inner part of oil seal extractor -3203- nine turns (approx. 20 mm) out of outer part and lock with knurled screw.

–  Lubricate threaded head of oil seal extractor -3203-, place it in position and, exerting firm pressure, screw it into oil seal as far as possible. –  Loosen knurled screw and turn inner part against crankshaft until the oil seal is pulled out. Installing seal: –  Remove oil residue from crankshaft journal using clean cloth.

–  Fit guide sleeve -T10053/1- onto crankshaft journal. –  Slide dry oil seal over guide sleeve onto crankshaft journal.

–  Press in oil seal using assembly tool -T10053- and bolt -T10053/2- (M16 x 1.5 x 60) onto stop.   Note t  Contact surface between pulley, diamond-coated washer and crankshaft must be free of oil. t  The centre bolt must be renewed. t  Thread and shoulder must be free of oil and grease.

–  Fit toothed belt pulley -2- with diamond-coated washer -3- and tighten bolt -1- hand-tight.

–  Lock toothed belt pulley using counterhold -3415-. –  Tighten new centre bolt to 90 Nm and turn 90° (1/4 turn) further (turning further can be done in several stages). Further assembly is basically the reverse of the dismantling sequence. Installing toothed belt and adjusting valve timing.    Vehicles with split toothed belt guard → Chapter.    Vehicles without split toothed belt guard → Chapter.
