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 gearshift rods -2- -arrow A-.
-- At the same time, the second technician lifts the input - reverse- and output shafts for 5th/6th gear and reverse gear -3- together with the gearshift rod out of the clutch housing -arrow B-.
If necessary, differential can be shifted again in clutch housing after lifting shafts.
-- Remove the input shaft seal.
Replace grooved ball bearing on drive axle after removing. Refer to OVERVIEW - INPUT SHAFT .
Assembling the Transmission
- A new grooved ball bearing is pressed onto the input shaft. Refer to OVERVIEW - INPUT SHAFT .
- The reverse gear shift fork -1- is placed on the 5th and 6th gear gearshift rod -2-. Refer to the information below.
-- Install the input shaft -1-, the 5th/6th gear output shaft -2- and the 5th/6th gear gearshift rod -3-, the reverse gear shift fork -4- and reverse shaft -5-.
- The shift jaw -arrow A- on the reverse gear shift fork faces the outside of the transmission. The shift jaw -arrow B- on the 5th/6th gear gearshift rod must face toward the inside of the transmission.
-- Then install the differential -1-.
A second technician is needed to help install the shafts into the clutch housing.
-- Hold the 1st through 4th gear output shaft -3- with the gearshift rods -4- in the right hand as illustrated.
-- Lift the differential slightly with your left hand.
-- Have the second technician lift the input shaft, the 5th/6th gear output shaft -2- together with the reverse shaft slightly at the same time.
-- Install the 1st through 4th gear output shaft in direction of -arrow-.
- Places of input shaft, output shafts and final drive gear/differential must engage.
-- Place the shafts and the differential in their bearing seats with a second technician.
-- Secure the : 30-211A for the input shaft to 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.
- The flattened sides -A- on the grooved ball bearing and on the bearing mount -B- must align in the transmission housing.
-- Mark this flat side with color.
-- Transfer the markings to the upper area of the grooved ball bearing and to the upper area of the transmission housing bearing mount (see next figure).
-- Heat the transmission housing in the area near the bearing seat for the grooved ball bearing/input shaft to approximately 100 °C (212 °F) for approximately 10 minutes using a : Hot Air Blower , for example, : VAG1416 .
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 marking on the grooved ball bearing -A- with the marking on the transmission housing -B- and mount the transmission housing.
-- Install the transmission housing and tighten the new bolts -A, B and C-.
Transmission with Reinforcement Measures (Manual Transmission 0FB)
-- Redetermine the locking ring -1- for the grooved ball bearing/input shaft -2- :
- Check that the input shaft with the : 30-211A is pressed up against the transmission housing.
