Disconnect spring No. 3 at its lower end (Figs. 74 and 75).
By means of the tool, shown in Fig. 47, remove the snap ring " 2 "
which is holding the pivot " C " of the stitch length lever " 4 "
(Fig. 74).
The stitch length lever " 4 " can be now taken out by pushing it
toward the inside of the machine.
Disengage the plate " 5 " by pushing down the reverse sewing
control button.
Note. Do not remove the bushing " 6 " with its retaining ring " 7
". In case the replacement of bushing " 6 " should be required,
care must be taken to the effect that the new bushing is placed in
the right position so that the free end of the small stud in plate "
5 " (Fig. 75) is neither too close to nor too far from the stitch
regulating shaft.
HOW TO REMOVE THE STITCH LENGTH REGULATING KNOB AND THE
REGULATING SHAFT (FIG. 75)
Loosen the screws "8", as well as the screws "10" on bush-
ing " 9 ".
Take off stitch length regulating knob " 12 ". In taking off this
knob, care must be taken so that washer " 16 " as well as spring
washers " 14 " (Fig. 75) are not lost.
Take off the regulating shaft "11 ", along with its pin " 13 ", by
drawing it toward you until the rear end of pin " 13 " comes out
of its hole.
HOW TO REASSEMBLE THE STITCH LENGTH REGULATING KNOB AND
THE REGULATING SHAFT
Take the regulating shaft " 11 " and insert the shorter end of its
pin " 13 " into the bushing " 9 ", as shown in Fig. 75.
