Coil spring seals:
Special tools and equipment
- 10-203 Oil seal driver
- 2085 Seal puller
- 3415 Counter support
- V.A.G 1331 Torque wrench (5 to 50 Nm)

PTFE seals:
Special tools and equipment
- 2085 Seal puller
- 3415 Counter support
- T10071 Assembly tool
- V.A.G 1331 Torque wrench (5 to 50 Nm)
- V.A.G 1332 Torque wrench (40 to 200 Nm)
Removing
- Remove toothed belt guard upper part.
- Set camshaft pulley to TDC No. 1 cylinder by turning crankshaft. Mark on camshaft pulley must align with (arrow) on toothed belt guard.
- Loosen tensioning roller and remove toothed belt from camshaft pulley.
- Turn crankshaft back slightly.
- Take camshaft pulley off. When loosening bolt hold camshaft pulley with counterhold 3415.
- Remove woodruff key from camshaft.
- Screw camshaft pulley bolt into camshaft onto limit stop.
- Unscrew inner part of oil seal extractor 2085 two turns (approx. 3 mm) out of outer part and lock with knurled screw.
- Lubricate threaded head of oil extractor, 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 camshaft until oil seal is pulled out.
- Clamp flats of oil seal extractor in vise. Remove oil seal with pliers.
Installing
Requirements
- Pistons must not be positioned at TDC.
NOTE:
- PTFE seals (Teflon) -2- have been introduced gradually to replace the coil spring type seals -1-. PTFE seals have a wider sealing lip.
- PTFE oil seals are installed free of oil and grease.
- An old type radial shaft seal (with coil spring) may be replaced by a PFTE seal (but a PTFE seal may not be replaced by a coil spring type).
- If PTFE seals are installed then only these seals may be used as replacement parts.
PTFE seals
NOTE:
Do not add oil or grease to the oil seal sealing lip.
- Position seal with assembly tool T10071 and press in onto limit stop with press sleeve T10071/1 and bolt T10071/2.
Coil spring seals
NOTE:
Lightly oil or grease the oil seal sealing lip.
- Position seal with fitting sleeve 10-203 and press into limit stop with press sleeve and bolt 10-203.
Continued for all oil seals
- Install woodruff key in camshaft.
- Install camshaft pulley. When tightening camshaft pulley bolt counterhold with 3415.
- Tightening torque: 100 Nm
NOTE:
When turning the camshaft the crankshaft must not be at TDC. Danger of damage to valves/piston crown.
Further installation is the reverse of removal.
