Pfaff 467 User Manual

The exact lime when bar Ba contacts the shaft may be determined by watching reverse feed
control p because at this time the latter starts descending. Loosen stitch length locking disc
o and turn stitch length control n
back to 0. When you depress reverse feed control p now, it
should swing down instantly without having any play. If the vibrating presser should make
any lengthwise motion
when stitch length control n is set on 0, adjust by turning crank LK
on its shaft (Fig. 43), as may be required.
To do this, remove the arm standard rear cover and loosen the set screw on the clamp crank
by inserting a screwdriver through the lower oval aperture. Adjust the position of crank LK
on its shaft and tighten the set screw securely again. If,as a result of zeroing the top and bottom
feeds, the position of the differential top feed scale should have been disturbed, center the
scale in relation to the top feed pointer. Check whether torsion springs DO and DU (Fig. 41)
are tensioned correctly and retension, if necessary.

35. Timing the Bottom Feed
When the machine is assembled at the factory, feed driving eccentric SE (Fig. 42) is adjusted
meticulously with the aid of precision instruments. Hence, there should be no need normally
to readjust the feed driving eccentric unless the basic timing relationship has been disturbed
while repairing the machine.
To check whether the drop feed motion is timed correctly, turn stitch length control n (Fig. 16)
to the maximum stitch length. Rotate the balance wheel until the needle bar has passed the
lowest point of its stroke and risen about V32", or 0.6 mm. Use all-purpose gauge No.
91-129 604-00 for this setting.
