Seals — replacement (Opel Omega B2)

Cardan shaft flange seal

1. See. Section 8 and detach the front end of the propeller shaft from the flange, then remove the vibration damper (where is available). If necessary, remove the shaft to gain easier 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) and a bolt with a nut split tool; the nut and bolt form a pivot point (see illustration).



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 (see illustration).



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 contact surface of the cardan shaft flange with the seal for damage and signs of wear. If any are found, replace the flange.

6. Clean the area around the seal opening and remove all traces of locking compound from the output shaft and flange nut threads.

7. Apply a small amount of grease to the outer sealing lip of the new oil seal, then turn the oil seal with the sealing lip inward and install it onto the end of the output shaft. Using a suitable tubular drift, (should rest only on the solid outer edge of the seal) carefully drive the seal to the depth measured before removing the old component.

8. Lubricate the oil seal with a small amount of transmission oil, then carefully install the propeller shaft flange into the operating position, being careful not to damage the sealing lip of the oil seal.

9. Apply a few drops of blocking compound (Opel recommends using 15 10 181) onto the thread of the flange mounting nut. Install the nut and tighten it to the tightening torque specified in the Specifications.

10. Install the driveshaft as described in Section 8, then check the transmission oil level (see Chapter 2).

Input shaft seal

Note: Leaks around the transmission input shaft may be caused by a leak at the input shaft seal or the clutch release cylinder O-ring. Replace both components regardless of their condition.

11. Remove the clutch release cylinder as described in Section 6.

12. Note the depth of the oil seal in the release cylinder, then carefully press it out using a large flat-head screwdriver.



13. Clean the area around the seal opening and apply a small amount of grease to the outer sealing lip of the new seal. Turn the seal with the sealing lip outward (to the transmission block when the cylinder is installed) and install it into the cylinder to the depth measured before removing the old seal. If necessary, use a suitable tubular drift (it should rest only on the hard outer edge of the gland).

14. Replace the O-ring and install the release cylinder as described in Section 6.
