Seals — replacement (Opel Omega B2)

Cardan shaft flange seal

Caution: A new flange O-ring and retaining nut are required.

1. Proceed as described in Section 8, detach the front end of the propeller shaft from the transmission flange and remove the vibration damper (where is available). If necessary, remove the shaft completely to facilitate access to the flange.

2. To lock the shaft when the nut is loosened, make a nut from two pieces of steel strip (one long, one short) forked tool, fastening them with a bolt and nut.

3. Lock the flange, then loosen and remove the mounting nut from the end of the transmission output shaft. Remove the tool and remove the flange along with the O-ring. Discard the nut and O-ring - they must be replaced.

4. Note the depth of the oil seal in the transmission housing, then carefully pry it out using a large flat-head screwdriver.

5. Check the sealing surface of the propeller shaft flange for damage and signs of wear. If any, replace the flange.

6. Clean the area around the seal bore, then apply a small amount of grease to the outer sealing lip of the new seal.

7. Position the seal with the sealing lip facing inward and install it to the previously measured depth using a suitable socket that rests only on the hard outer edge of the seal.
