Removal and installation the crankshaft pulley, replacing the front crankshaft oil seal (engine 1.8) (Skoda Superb B6)

Removal and installation the crankshaft pulley

Note: Crankshaft pulley installation details are shown in Illustration 24.1.

1. Remove the sound insulation under the engine compartment, as well as the right front wheel arch liner (see Chapter 11).

2. On models with additional heating, loosen the clamp (1 in illustration 15.14), unscrew the bolt (2) and remove the additional heater muffler.

3. Remove the accessory drive belt (see Section 24).

4. Remove the bolts (arrows in the accompanying illustration) and remove the air tube by lifting the clamps (1 and 2).



5. Using the T10355 key, turn the crankshaft clockwise to the position corresponding to the TDC of piston No.1. In this case, the notch on the pulley should be opposite the mark on the lower timing chain cover (see accompanying illustration). Holding the pulley in this position with the T10355 key, unscrew its mounting bolt and remove the pulley. After removing the pulley, do not turn the crankshaft so as not to disturb the timing adjustment.





6. Installation is carried out in the reverse order. Remove any remaining oil from the crankshaft journal with a clean cloth and install the pulley, paying attention to the shape of the tooth (arrow on the accompanying illustration). Use a new pulley mounting bolt and a new O-ring (1).

Replacing the front oil seal

Note: The front crankshaft oil seal is installed in the lower timing chain cover (see illustration 27.1).

7. Remove the crankshaft pulley (see subsection above).

8. Screw the pulley mounting bolt back in with the pressure plate T10368 and pull out the oil seal using the puller T20143 (see accompanying illustration).



9. Clean the seal seating surface of the timing chain cover from oil and grease and press the new seal until it stops using the T10354 mandrel and the pulley mounting bolt (see accompanying illustration).





10. Install the pulley.
