Input Shaft

Input Shaft

Special tools, testers and auxiliary items required

• Puller (T40050)

Removing

• Observe general repair information. Refer to => [ General Repair Information ] General Repair Information.

• Rules of cleanliness for working on transmissions. Refer to => [ Clean Working Conditions ] Clean Working Conditions.

• Transmission removed and secured vertically to assembly stand. Refer to => [ Suspending Transmission Vertically ] Securing Transmission to Assembly Stand.

- Drain the ATF. Refer to => [ ATF, Draining for ATF Flushing Process ] ATF Flushing. Pivot transmission in installation position (level),

• Transmission must not be turned so that flange points downward.

- Remove bolts - arrows -.





- Using a plastic mallet, carefully hit the input shaft flange cover so that the cover loosens itself from the seal.

- Secure puller (T40050) on the transmission input shaft.





- Check puller (T40050) for secure seating on the input shaft.

• Circlip must be pushed all the way down.

- Pull the input shaft with flange cover and forward clutch out of the transmission housing in direction of - 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 the reverse order of removal, note the following:

- Check the wear on the transmission components. Refer to => [ Input Shaft Checking for Wear ] Testing and Inspection.

- Clean the sealing surfaces on the transmission housing and flange cover.

- Check whether bushings - arrows - for centering the flange cover on the 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 the 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 approximately 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 counterclockwise over the last few millimeters so that it engages in the teeth of the helical intermediate gearing.

- Tighten bolts - arrows - in a diagonal sequence and in stages.





- Fill with ATF. Refer to => [ ATF Filling for Flushing Process ] ATF Flushing.

CAUTION!
• The Multitronic 01J transmission requires a different ATF than shift automatics. Only ATF for CVT transmissions which can be obtained as replacement part must be used in planetary gearing.

• Flush ATF after installing transmission. Refer to => [ ATF Flushing ] ATF Flushing.
