If the surface of the input shaft is visibly damaged near the needle bearing in the dual mass flywheel -arrow-, then replace both the input shaft and the needle bearing in the dual mass flywheel.
Replace the drive shaft. Refer to TRANSMISSION, DISASSEMBLING AND ASSEMBLING .
Depending on the version, the following bearings are installed in the dual mass flywheel:
- Needle bearing -A- that has a complete set of rollers
- Needle bearing -B-, that is missing every 4th roller -arrows- does not indicate a faulty needle bearing.
- New needle bearings are equipped with rollers.
- Ball bearing -C-.
- Allocate correct components .
Removing
- The clutch pressure plate and clutch plate are removed from the dual mass flywheel. Refer to CLUTCH, REMOVING AND INSTALLING, "Single-Disc Clutch - LuK" or CLUTCH, REMOVING AND INSTALLING, DUAL DISC CLUTCH .
-- Tension the Internal Puller -A- behind the sealing lip on the shaft seal -B- and pry out the seal.

Internal Puller 30 to 37 mm, for example, Puller - Kukko Internal - 28-37mm 21/5
The dual mass flywheel could be damaged.
- If the dual mass flywheel is supported on the transfer plate -B-, it will distort and be damaged. The dual mass flywheel must then be replaced.
- Always replace the needle bearing after removing from the dual mass flywheel
-- Remove the shaft seal from the dual mass flywheel. Refer to Fig 3.
-- Install the Internal Puller -A- near the seal -arrow- in the needle bearing and tighten down on it.
A -
Puller - Kukko Internal - 20-30mm, for example 21/4
-- Install the Bearing Installer - Clutch Housing/Gearbox Bearing VW554 on the Internal Puller and remove the needle bearing.

- The centering pins on the dual mass flywheel could get damaged when installing the needle bearing.
- The dual mass flywheel may be supported only in the center under the needle bearing mount.
-- Remove any grease still on the hole for the needle bearing inside the dual mass flywheel using a dry towel.
Do not use any cleaning solution to clean the hole!
-- Support the dual mass flywheel directly beneath bearing mount using Bearing Installer - Differential Bearing VW511.
-- Install the Press Piece - Multiple Use 30-11 with the small diameter into the needle bearing -A-. The side of the needle bearing with the writing (the larger metal thickness) faces the Thrust Pad.
-- Carefully install the needle bearing all the way in.
- The needle bearing is installed inside the dual mass flywheel.
- The open side of the shaft seal faces the transmission.
- Attach the clutch pressure plate with the clutch plate to the dual mass flywheel. Refer to CLUTCH, REMOVING AND INSTALLING, "Single-Disc Clutch - LuK" or CLUTCH, REMOVING AND INSTALLING, DUAL DISC CLUTCH .
