Disassembly

- Install the transmission to the assembly stand with the bolts - arrows -.

If one of the bolt holes does not touch the transmission support, place shims between the hole and the transmission support.






- Turn the transmission in the assembly stand so that the drain plug is facing down.

- Place a drip tray underneath.

- Drain the fluid from the manual transmission.

- Remove the right flange shaft (the illustration shows the left flange shaft).






- Remove the slave cylinder with the release bearing bolts - arrows - and slave cylinder.






- Remove the bolts - B - that secure the clutch housing to the transmission housing.






One bolt - arrow - is located outside of the bolting flange.

- Secure the input shaft.

The stub shaft splines on the input shaft has different lengths on the transmission.

- Either place the thrust tube (VW 455) over the input shaft on the clutch housing.






- Or, place the sleeve (3160) over the input shaft on the clutch housing.






- Tighten the separating tool - A -, for example, Kukko separating tool 5-60 mm (17/0) , securely behind the splines on the input shaft.

The back of the separating tool must touch the thrust tube (VW 455) or the sleeve (3160) free of play.

- Remove the left flange shaft.






Make sure the gear shift shaft is not blocked by the locking pin - arrow -.






- Move the gear shift shaft into neutral.

- Remove the locking screw - 2 -.

- Then remove the bolts - 3 -.

- Remove the backup lamp switch (F4) - 1 -.

- Remove the gear shift shaft - 4 - from the transmission housing.

With a Metal Cover:






- Remove the sealing cap circlip - A -.

- Pierce the rubber cover - C - in the center using a screwdriver.






- Remove the cover from the transmission housing.

A Counter support, for example, Kukko support (22/1)
B Internal puller, for example, Kukko puller 12-14.5 mm (21/01)

With a Plastic Cover:






Carefully remove all tabs - A -. Do not damage the transmission housing when doing so.

- Pry out the cover.






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.

- Install the backup lamp switch (F4) - 1 -.

- Install the input shaft seal so that it is flush.






- Install the slave cylinder with release bearing. Refer to => [ Slave Cylinder with Release Bearing ] Slave Cylinder with Release Bearing.

- Move the gear shift lever (selector lever) through all the gears.

- Install the cover.
