Replacing needle bearing for dual-mass flywheel   Note

t  If there is visible damage on the surface of the input shaft in the vicinity of the needle bearing for the dual-mass flywheel -arrow-, both the input shaft and the needle bearing in the dual-mass flywheel must be renewed . t  For input shaft replacement, refer to → Chapter „Fitting sequence - dismantling and assembling gearbox “.

Depending on the version, different types of needle bearing are fitted in the dual-mass flywheel. t  Needle bearings with the full number of rollers. t  Needle bearing with every 4th roller missing -arrows- (this does not constitute a needle bearing fault). t  New needle bearings have the full number of rollers.

t  -1-Internal puller -Kukko 21/4- t  -1-Internal puller -Kukko 21/5- Removing l  Clutch pressure plate and clutch plate detached from dual-mass flywheel → Chapter.

Removing oil seal from dual-mass flywheel –  Clamp internal puller-A- behind sealing lip of oil seal -B- and pry out oil seal. A -  Internal puller 30 ... 37 mm, e.g. -Kukko 21/5-

Pressing needle bearing out of dual-mass flywheel   Caution Take care not to damage dual-mass flywheel. If the dual-mass flywheel is supported on the flange for drive plate -B-, the flange will become distorted and the flywheel will thus be damaged. In this case, the dual-mass flywheel will have to be renewed. l  Always renew the needle bearing when it has been removed from the dual-mass flywheel. –  Remove oil seal from dual-mass flywheel → Fig.. –  Apply internal puller-A- in area of seal -arrow- in needle bearing and tighten puller. A -  Internal puller 23.5 ... 30 mm, e.g. -Kukko 21/4- –  Then apply press tool -VW 554- to internal puller and press out needle bearing.

Pressing in needle bearing for dual-mass flywheel (press onto stop)   Caution Take care not to damage dual-mass flywheel. t  The centring pins at the dual-mass flywheel may be damaged when pressing in the needle bearing. t  The dual-mass flywheel must always be supported centrally under the bearing mounting for the needle bearing. –  Remove remaining grease in bore for needle bearing in dual-mass flywheel using a dry cleaning cloth.   Note Do not use solvent for cleaning bore. –  Support dual-mass flywheel with thrust pad -VW 511- directly below bearing mounting. –  Insert smaller diameter of thrust plate -30-11- in needle bearing -A-. Lettering on needle bearing (thicker metal) must face towards thrust plate. –  Carefully press in needle bearing as far as stop.

Driving oil seal into dual-mass flywheel (drive in onto stop) l  Needle bearing is installed in dual-mass flywheel. l  Open side of oil seal faces towards needle bearing. l  Attachment of clutch pressure plate and clutch plate to dual-mass flywheel → Chapter.
