–  Allocate locking collar and synchro-hub for 5th and 6th gears according to → Electronic parts catalogue “ETKA”.
Due to the deeper notches, the adjustment procedure for 5th and 6th gears has been changed:
–  Adjusting 5th and 6th gears through gearbox manufacture date 11 06 6 → Fig.
–  Adjusting 5th and 6th gears from gearbox manufacture date 12 06 6 → Fig.
   
Dismantling and assembling locking collar and synchro-hub for 5th and 6th gears
1 - Spring
2 - Locking piece
3 - Synchro-hub
4 - Locking collar
–  Slide locking collar over synchro-hub.
Deeper notches -arrow A- for locking pieces in synchro-hub and notches -arrow B- in locking collar must align.
  N35-0365
Assembling locking collar and synchro-hub for 5th and 6th gears
l  Locking collar has been pushed over synchro-hub.
–  Insert locking pieces in deeper notches -arrows- and install springs offset 120°. Angled end of spring must locate in hollow locking piece.
  Note
t  From gearbox date 26 05 8, a wave spring washer is installed below the synchro-ring for 5th gear and above the synchro-ring for 6th gear → Item and → Item.
t  In this case, install only locking piece springs without angled ends. (As shown in → Fig. - item 1-)

Installing springs with bent ends -A-
The modified springs are installed on both sides.
–  Modified springs can be installed in earlier gearboxes only in conjunction with locking pieces which are hollow on the inside.
–  Insert locking pieces.
  N35-0336
Installation position of springs:
–  Install springs offset 120°.
–  Angled end -A- of spring must locate in hollow locking piece.
It must be located under shoulder -B- of locking piece.
Bent ends always face away from synchro-hub -direction of arrow-.
