Installation of the needle bars in the needle bar linkage
–
Insert the needle bar 7 in the linkage 1 from below.
–
Insert the needle bar in yoke 14 and clamping ring 13. The thin side
of the clamping ring must point to the other needle bar and its
indentation must point upwards.
–
Push up the needle bar so that the three lower ball holes 3 are still
below the linkage.
–
Insert three balls 4 in the lower ball holes 3. Use grease to avoid
that the balls drop out.
–
Push the needle bar upwards so that the lower balls disappear and
the upper ball holes 5 become visible.
–
Insert the three balls 6 in the upper ball holes 5.
–
Hold the needle bar tight and press the decoupling bar 2 into the
needle bar.
–
Simultaneously pull the yoke 14 down half over the upper balls 6.
ATTENTION !
Now the needle bar and the yoke must not be shifted
any more because otherwise the balls being under spring pressure
might come out.
–
Push the clamping ring 13 down the needle bar until the annular
slot 9 lies exposed.
–
Place the two securing halves 8 in the annular slot. Push the
clamping ring 13 upward as far as it will go so that the securing
halves lie in the indentation.
–
Press the yoke 14 upward against the clamping ring 13 as far as it
will go so that the needle bar is coupled with the yoke.
–
Screw in needle holder 11 and fasten by means of screw 12.
–
Turn the needle bar in such a way that the fronts of both needle
holders are at the same level.
