- Drain the oil from the gearbox. Remember that either automatic transmission fluid or gearbox oil is being poured in.
- Disconnect the drive shaft from the gearbox in accordance with the instructions in Chapter 11.1. Depending on the engine type, it may also be necessary to remove the middle drive shaft and unscrew it from the cylinder block.
- On the C52 gearbox, unscrew the cover on the left side and press the oil seal out of the cover.
- On the S50 gearbox on the left side, and on other gearboxes on the right side, use a suitable impact puller to pull out the seal. Figure 172 shows the use of the tool. If such a tool is not available, you can screw one or two screws into the seal and pry the seal with a screwdriver inserted under the screw heads.
Fig. 172. Removing the seal from the gearbox side. On the left side of the S50 type gearbox, the side cover must be screwed on.
- Lubricate the lips of the new seal and press it either into the cover or into the gearbox without damaging the seal.
- Install the drive shaft and, if present, the intermediate shaft as described in Chapter 11.1. Check the fit of the retaining ring in the shaft groove. There should be a noticeable gap of 2-3 mm. In addition, it should be impossible to pull the shaft out by hand.
- With the intermediate shaft installed, screw the support onto the cylinder block. Fill the gearbox with oil (box C52) or liquid (box S50). Both boxes require about 2.6 liters. Screw in the filler cap.
