Remove any locking fluid residue still in the threaded holes using a tap if the shafts are not going to be replaced.
-- Remove both bolts -arrows- for the reverse shaft support.
-- Remove the 3rd bolt -arrow- from the reverse shaft support.
-- Move the gear shift shaft into neutral and remove the gear shift shaft with the gear shift cover. Remove the bolts -arrows- and pull the gear shift shaft out of the transmission housing.

-- Remove the support pins -A- on the top side of the transmission and remove the transmission housing to clutch housing bolts -B- in the area of the differential.
-- Remove the clutch housing to transmission housing bolts -A- .
Do not remove the nuts -B- for the output shaft bearing support.
-- Remove both flange shafts.
-- Remove the flange shafts with the springs, thrust washers and tapered rings.
Remove the following components together with the transmission housing:
- 5th gear synchronizer hub
- 5th gear
- Both plates T10408/3 must be attached to the 5th gear.
- The plates T10408/3 must be located above the two ribs on the housing, opposite each other -arrows- .
There is a needle bearing under the 5th gear.
Secure the plates T10408/3 so that the needle bearing does not touch the 5th gear when removing the transmission housing.
Use the puller T10408 together with the following special tools:
- Thrust piece T10408/2
- Plates T10408/3
- Puller - Kukko Puller - 60-150mm Width, 200mm Length 18/1 (Qty: 2)
-- Install the plates T10408 to the threaded holes in the transmission housing cover using the bolts -A- .
