- Measure distance between body and rear push
rod (in selector mechanism).

If that is not the case, obtain distance -a- as follows:
Specification: distance a = 43 mm

- Loosen bolt (arrow) for pivot rod.

Rear pivot rod (in shift control mechanism) must move freely back
and forth on sliding piece.
- Adjust measurement -a- by moving pivot rod rear (in shift control
mechanism).
- Tighten bolt for pivot rod to 25 Nm.

The illustration shows the gear shift from the right.
Note:
The gear shift must remain in the same position while the bolt is being
tightened.
Gear shift inclined slightly backwards (approx. 7 , angle b)
- Hold gear shift in this position.
- Tighten selector rod bolt to 25 Nm.

Gear shift adjustment, checking


The gear shift lever must rest in the 3rd/4th
gear gate when transmission is in neutral.

- Check operation of 1st and 2nd gear stop.

- Engage 2nd gear and push gear shift to the left
against the stop.

- Reduce pressure on gear shift until it moves
back to pressure point.

Spring-back measured at gear shift handle: 3-5
mm

- Check that all gears can be engaged.

- Check operation of reverse gear lock.


It should only be possible to engage reverse
gear after pressing the gear shift down to
overcome the reverse gear lock.

It must be possible to move the gear shift,
without pushing and without force, forwards
from the reverse gear lock to the 3rd/4th
gear plane
