Removing
• The flange shaft/driveshaft seal can be replaced only when the rear final drive is removed.
Observe general repair notes => [ To perform a problem-free and successful
transmission repair, extreme caution and cleanliness, as well as properly
functioning tools are an important requirement. Understandably, general safety
guidelines apply when performing repairs. ] Component Description.
- Remove rear final drive. Refer to => [ Rear Final Drive ] Rear Final Drive.
- Attach the rear final drive to the holding fixture (VW 540) using M10 x 40 bolts - arrows -.
- Measure the friction torque before loosening the pinion nuts.
- Write down this value.
If, during the repair, the flange/driveshaft must be replaced, then this measured value must be adjusted again. Refer to => [ Flange/Driveshaft and Seal with Rear Final Drive Removed ].
- Mark the location of the pinion nut on the pinion - arrow -.
Determining Dimensions a and b
• Distance between the flange and the pinon = dimension - a -
• Distance between the flange and the pinon nut = dimension - b -
- Write down the dimensions.
- Attach the (3028) to the flange/driveshaft with the bolts - A -.
- Attach the (T10235) in the threaded hole under the flange/driveshaft.
- Loosen the pinion nut. The (3028) will be supported by the (T10235) - arrow -.
- Count the number of turns when removing the pinion nut and write this number down.
- A - three M8 x 25 bolts
- B - 32 mm socket
- C - bar
- Mark the location of the flange/driveshaft - arrow A - to the pinion - arrow B -.
- Place the drip tray underneath.
- Install the (VW 391) with two M8 x 25 bolts - arrows -.
- Remove the flange/driveshaft.
- Remove the shaft seal.
- Clean the thread on the pinion.
Installing
Installation is in reverse order of removal. Observe the following when doing so:
- Coat the outer circumference of the shaft seal with gear oil.
- Fill the space between the sealing and dust lips halfway with sealing grease (G 052 128 A1).
- Install the new shaft seal all the way without tilting it.
- Warm the flange/driveshaft to approximately 80 °C (176 °F) with an (VAS 6414).
- Line up the markings on the flange/driveshaft - arrow A - and pinion - arrow B -.
- Install the flange/driveshaft.
- Install the old pinion nut with locking fluid (AMV 185 101 A1).
- Attach the (3028) to the flange/driveshaft with the bolts - A -.
- The (3028) must be supported by the housing brace - arrow - when tightening the pinion nut.
- A - three M8 x 25 bolts
- B - 32 mm socket
- C - bar
- Tighten the pinion the number of turns noted earlier when it was being removed at the marked location - arrow -.
Checking dimensions a and b
• Measurement deviation: ± 0.2 mm
- Install rear final drive. Refer to => [ Rear Final Drive ] Rear Final Drive.
- Check the gear oil in the rear final drive. Refer to => [ Rear Final Drive Gear Oil, Checking ] Rear Final Drive 0BD (0B2A,0B6A,0B4A,0B5A,0BKA Transmission).
