Opel Corsa B 1993–2000 Service and Repair Manual: Camshaft toothed belt tensioner and idler rollers - removal and refitting

Removal

1. Remove the toothed belt.

2. Remove the Allen screw which secures the belt tensioner. Lift off the tensioner and its mounting plate and recover the spacer sleeve.

3. Similarly unbolt and remove the idler roller and recover its sleeve.

4. Renew the rollers if they show roughness when spun, or if they have been noisy in operation.

Refitting

5. Refitting is the reverse of the removal procedure, noting the following points:

  1. Make sure the spacer sleeves are the right way round. The smaller diameter of the tensioner sleeve goes towards the block.

    The smaller diameter of the idler sleeve goes away from the block.

  2. Tighten the screws to the specified torque.
  3. Fit a new camshaft toothed belt.

Camshaft sprocket oil seals - renewal

1. Remove the camshaft toothed belt.

2. Remove the camshaft cover and the camshaft sprockets.

3. Punch or drill a small hole in the face of one of the oil seals. Screw in a self-tapping screw and use this to lever the seal out. Clean the seal seat.

4. Grease the lips of a new seal and fit it, lips inwards. Seat the seal by tapping it home using a mallet and a large socket or a piece of tube (see illustrations).
