This must be raised further until the distance
between the upper edge of the insert sleeve and
the edge of the stem guide is approx. 5 mm.
♦
In order to raise the spindle
802
into this position,
the adjusting screw
538
is now pre-tensioned
approx. 25 mm (turned into the bonnet). Then
mount a distance sleeve approx. 35 mm long (or
hex. nuts with U-washer, see
Fig. 18
) onto the now
free spindle end.
♦
Grease the end surfaces of the spacer sleeve well
so that these surfaces cannot "seize".
♦
A hex. nut is screwed onto the spindle end and
countered with another hex. nut. See
Fig. 18.
♦
Undo adjusting screw
538
(turn out of the spring
bonnet
513
) until the distance between the upper
edge of the insert sleeve and the edge of the stem
guide is approx. 5 mm. See
Fig. 24.
♦
When undoing the adjusting screw
538
, hold the
spindle
802
with a wrench on the counter nut to
prevent it from turning so that the bellows
206
or
the spring-type pin
939/1
are not damaged.
