Renewing crankshaft oil seal - pulley end

Special tools and workshop equipment required

t	Toothed belt pulley counterhold tool -3099-

t	Oil seal extractor -2085-

t	Fitting sleeves -T10132-

t	Torque wrench -V.A.G 1332-

Note

t  A PTFE oil seal is being gradually introduced (Teflon) -2- in place of oil seal with internal circular spring -1-. This has a wider sealing lip. PTFE oil seals are installed free of oil and grease. t  An older design radial shaft seal (with coil spring) may be replaced by a PTFE seal, but not the other way around. Removing: –  Remove poly V-belt → Chapter. –  Remove toothed belt → Chapter. –  Remove crankshaft toothed belt pulley.

To do this, lock toothed belt pulley using counterhold tool -3099-. –  Screw inner part of oil seal extractor -2085- two turns (approx. 3 mm) out of outer part and lock with knurled screw.

–  To guide seal extractor, screw socket head bolt -T10132/3- into crankshaft onto stop.

–  Lubricate threaded head of oil seal extractor -2085-, 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: Install PTFE oil seals “dry”. Lightly oil coil spring oil seals. –  Clean crankshaft journals with a clean cloth.

–  Fit guide sleeve -T10132/1- onto crankshaft journal. –  Slide oil seal over guide sleeve.

–  Press seal in with fitting sleeve -T10132/2- and bolt -T10132/3- to stop.

–  Install crankshaft toothed belt pulley and lock with counterhold tool for toothed belt sprocket -3099-. –  Tighten new centre bolt to 90 Nm and turn 90° (1/4 turn) further (turning further can be done in several stages). –  Installing toothed belt and adjusting valve timing → Chapter.
