Remove : - the cardan,
- the shim (s)
Reassembly : Adjust the pre-depression of the cardan by
selecting the shims necessary to obtain play-free contact
between the switch-plate and the plungers. In neutral position,
the depression of the plungers must not exceed 0.2 mm. In
order to check this value, observe the displacement of the
plunger located opposite to the one being pressed.
