Internal Components

Input shaft, removing and installing - 01J, Continuously Variable Transmission (CVT)

Special tools, testers and auxiliary items required





^ Puller T40050

Removing

Note:
^ Observe general repair notes.
^ Rules of cleanliness for working on automatic transmissions.

^ Transmission removed and secured vertically to assembly stand.

- Drain ATF, pivot transmission in installation position (level).

Note:
^ Transmission must not be turned so that flange points downward.





- Remove bolts - arrows -.
- Using a plastic mallet, carefully knock input shaft flange cover so that input shaft flange cover loosens itself from seal.





- Secure Puller T40050 on transmission input shaft.
- Check Puller T40050 for secure seating on input shaft.

^ Circlip must be pushed all the way down.

- Pull input shaft with flange cover and forward clutch on Puller T40050 out of transmission housing - arrow -.

CAUTION!
^ Input shaft must not be set down on the projecting oil pipe - arrow - otherwise it will be damaged.
^ If the oil pipe is damaged, starting problems or a transmission malfunction will result.





CAUTION!
The reverse gear clutch plates must not be removed from the transmission housing.

Installing

Install in reverse order of removal, note the following:

- Check wear on transmission components
- Clean sealing surfaces on transmission housing and flange cover.





- Check whether bushings - arrows - for centering flange cover on transmission housing are installed and seated securely.





- Check condition of sealing ring - arrow -, replace if necessary.

^ Installation position of oil seal: Sealing lip towards flange cover.

- Place paper gasket in position.





- Align clutch discs of reverse gear clutch e.g. using a straight-edge.

^ Splines must stand exactly in a row.





- Check installation dimension of oil pipe - arrow -:

^ If oil pipe is inserted completely, the dimension from its end to the input shaft is approx. 11.5 mm.

If the dimension is smaller, the oil pipe possibly is damaged as it was pushed in too far and is broken at the end.

If the dimension is larger, it is not pushed in far enough.

CAUTION!
^ Input shaft must not be set down on the projecting oil pipe - arrow - otherwise it will be damaged.
^ If the oil pipe is damaged, starting problems or a transmission malfunction will result.

- Insert entire input shaft into transmission housing.





- Use back and forth rotating motions - arrow - on input shaft until clutch discs of reverse gear clutch have engaged. Raise input shaft slightly when doing this.
- Just before the input shaft is fully in position, rotate it counter-clockwise over the last few millimeters so that it engages in the teeth of the helical intermediate gearing.





- Tighten bolts - arrows - in diagonal sequence and in stages.
- Fill with ATF.

CAUTION!
^ The Multitronic 01J or 0AN transmission requires a different ATF than shift automatics. Only ATF for CVT transmission which can be obtained as replacement part must be used in planetary gearing.
^ Flush ATF after installing transmission.
