• Ensure that the individual cover parts are removed as necessary.
Continuation for all:
Remove the locking ring - C - from the grooved ball bearing on the input shaft/transmission housing as follows:
- Hold one end of the locking ring secure using a screwdriver - A -.
- Pry the other end out of the groove in the grooved ball bearing in the - direction of the arrow - using the another screwdriver - B -.
- Pry out the rest of the locking ring using the screwdriver - B -.
- Remove the bolts - A - that secure the transmission housing to the clutch housing.
- Install adapter (VW 771/40) into the threaded hole in the transmission housing.
- Heat the transmission housing using, for example, the heat gun (V.A.G 1416) , in the area of the bearing seat for grooved ball bearing/input shaft to approximately 100 °C (212 °F) for approximately 10 minutes.
- Remove the transmission housing from the clutch housing in the - direction of the arrow - using the slide hammer (VW 771/1).
• If necessary, carefully pry up all around and alternating between sides on the protruding flange. Be careful not to damage the sealing surfaces.
- Remove the separating tool - A - and the thrust tube (VW 455) (illustration) or the sleeve (3160) from the input shaft.
A second technician is needed to help remove the shafts from the clutch housing.
- Lift the differential - 1 - with the left hand. With the right hand, lift the output shaft for 1st to 4th gear together with the selector shafts - 2 - - arrow A -.
- At the same time, the 2nd technician lifts the input, reverse and output shaft for 5th/6th gear - 3 - together with the selector shaft out of the clutch housing - arrow B -.
• If necessary, the differential can be shifted again in the clutch housing after lifting the shafts.
- Pry out the input shaft seal using the extractor lever (VW 681).
• Always replace the grooved ball bearing => [ (Item 6) Grooved Ball Bearing ] Input Shaft Overview on the input shaft.
Assembly
• Press the new grooved ball bearing => [ (Item 6) Grooved Ball Bearing ] Input Shaft Overview onto the input shaft.
- First, insert the input shaft - 1 -, output shaft for 5th and 6th gears - 2 - together with the selector shaft - 3 -, reverse gear selector fork - 4 - and reverse gear shaft - 5 -.
Pay attention to the different bearing for the reverse gear selector shaft.
Reverse gear selector fork - 1 - mounted on the selector shaft - 2 - behind the 5th and 6th gear selector shaft - 3 -:
Reverse gear selector fork - 1 - mounted on the selector shaft with the 5th and 6th gear selector fork - 2 -:
Continuation for all:
- Then install the differential - 1 -.
• A 2nd technician is needed to help install the shafts into the clutch housing.
- Hold the output shaft for 1st through 4th gear - 3 - and the selector forks - 4 - with the right hand.
- Slightly lift the differential with the left hand.
- Have the second technician lift the input shaft, the 5th and 6th gear output shaft and reverse gear - 2 - together with the reverse shaft slightly at the same time.
- Install the 1st to 4th gear output shaft in the - direction of the arrow -.
• Places of the input shaft, output shafts and final drive gear/differential must engage.
- Together with a second technician, now place the shafts and differential in their bearing seats.
- Install the bracket (30-211A) to the input shaft and the clutch housing.
• The clutch housing is shown in the illustration rotated 180°.
- Install the bolt - A - just far enough until the input shaft starts to lift.
The grooved ball bearing/input shaft only fits in one position in the transmission housing.
There is a flattened area on the grooved ball bearing and the bearing mount.
• If the flattened areas - A and B - are present, do not insert any washers above and below the grooved ball bearing. Refer to => [ Grooved Ball Bearing Changes ] Input Shaft.
• The flattened sides - A - on the grooved ball bearing and on the bearing mount - B - must align in the transmission housing.
- Mark the flattened side with color.
- Transfer the marks to the upper area of the grooved ball bearing and to the upper area of the transmission housing bearing mount (=> next illustration).
- Heat transmission housing using, for example, the heat gun (V.A.G 1416) , in the area of the bearing seat for the grooved ball bearing/input shaft to 100 °C (212 °F) for approximately 10 minutes.
• It is necessary to heat the transmission housing so that the grooved ball bearing is not damaged when the housing is being installed.
• Apply sealing paste (AMV 188 200 03) evenly onto the sealing surface of the clutch housing.
• Align the mark on the grooved ball bearing - A - with the mark on the transmission housing - B - and install the transmission housing.
- Install the transmission housing and tighten the bolts - A, B and C - to specification.
If the steel bolts (outer hex head) are the replacement part, pay attention to the allocation:
A Bolt with a permanent washer
B Bolt without washer
C Bolt with a permanent washer
- Install the grooved ball bearing/input shaft locking ring - 1 -.
- Remove the bracket (30 - 211 A) from the input shaft.
- Install the selector shaft lock sleeve all the way onto the tool. Refer to => [ Lock Sleeve Differentiation ] Transmission Housing.
- Turn the transmission with the opening for the selector shaft in the assembly stand upward.
- Install the gear shift shaft - 1 - into the lower bearing - 2 - and into the selector forks - 3 -.
• The cover is not shown in the illustration.
- Push the gear shift shaft - 1 - against the retaining sleeve - 2 - in the - direction of the arrow - and guide is through the selector fork all the way down using the shift finger - 3 -.
• The gear shift cover - 4 - must be parallel to the bolting surface on the transmission housing.
• It must be possible to move the gear shift shaft easily (forward and backward).
• If the gear shift cover is at an angle to the bolting surface, then the gear shift shaft is not installed into the lower bearing.
- Tighten the bolts - 3 - for the gear shift cover - 4 -.
- Install the locking screw - 2 -, the locking pin - arrow - must not be installed when doing so.

- Move the gear shift lever (selector lever) through all the gears.
- Install the cover.
Cover differentiation
- I - = metal cover; secured with circlip - A -.
- II - = plastic cover; without a circlip.

- Secure the cap with the circlip - A -.
Plastic Cover
- Install the cap all the way into the transmission housing.
Continuation for all:
• Always pay attention to the cover allocation, refer to => [ Allocation ].
• Leaks in the case of incorrect installation.
