Action
Put the lower arm in its mounting position.
If the hole pattern needs to be adjusted, use a
crank to move the gears in order to find the cor-
rect hole pattern.
Note
Refit the axis 2 side first!
Verify that the sealings are still in place.
Refit all screws (both M12 and M16) and wash-
ers, that are possible to fit at this stage, on the
axis 2 side.
Push the parallel arm against the axis 3 side with
the help of an iron bar or similar.
Refit all screws and washers, that are possible
to fit, on the axis 3 side.
Note
The axis 3 side has no M16 screws!
Remove the guide sleeves and secure two
screws more.
Change the position of the lower arm in order to
reach the remaining attachment holes, and fit
the remaining screws.
