For vehicles with PTFE oil seals:

t  Assembly tool -T10053+3- Removing –  Removing poly-V-belt and tensioner → Chapter. –  Remove toothed belt → Chapter.

–  Remove crankshaft toothed belt pulley. To do this, lock toothed belt pulley using counter-hold tool -3415-.

–  To guide seal extractor, screw centre bolt into crankshaft to stop by hand. –  Unscrew inner part of oil seal extractor -3203- two turns (approx. 3 mm) out of outer part and lock with knurled screw.

–  Lubricate threaded head of oil seal extractor -3203-, place in position and exerting firm pressure, screw it as far as possible into oil seal. –  Loosen knurled screw and turn inner part against crankshaft until the oil seal is pulled out. Installing   Note! Gradual introduction of PTFE seals (polytetrafluoroethylene) Characteristics: no coil spring, wider sealing lip. The sealing lip of this oil seal must not be additionally oiled or greased. A older design radial shaft seal (with coil spring) may be replaced by a PTFE seal, but not the other way around. –  Remove oil residue from crankshaft journal using a clean cloth. Installing oil seal with coil spring –  Lightly oil sealing lip of oil seal.

–  Position guide sleeve from fitting sleeves -2080 A- onto crankshaft journal. –  Slide oil seal over guide sleeve onto crankshaft journal.

–  Press oil seal in with fitting sleeve -3265-. Use old crankshaft toothed belt pulley central bolt -1- to do this. –  Press oil seal in 2…3 mm. Installing PTFE oil seal

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

–  Press in oil sleeve to stop with pressure sleeve from assembly tool -T10053- and bolt -T10053/2- (M16 x 1.5 x 60). Continuation for all oil seals

–  Install crankshaft toothed belt pulley and lock with counterhold tool -3415-. –  Tighten new centre bolt to 90 Nm and turn 90° (1/4 turn) further (turning further can be done in several stages).   Note! Thread and shoulder must be free of oil and grease. –  Install toothed belt and adjust valve timing → Chapter. –  Installing poly-V-belt and tensioning element → Chapter.
