2. Refer to Figure 3-28 and insert the needle case lower rail into the lower rail
retainer. Insure the grabber blade fits into the grabber bar assembly at the
bottom of the needle case.
3. Rotate the upper part of the needle case into position on the front of the head as
you insure the following alignments:
a) All the take up lever slots are positioned onto the take up lever guide rail
and the active take up lever gear teeth are engaged with the take up
lever drive gear teeth. With the embroidery head still in the head up
position, insure the top tooth of the take up lever drive gear engages
with the 5th "valley" of the take up lever gears.
b) The needle case color change pins fit into the color change cam properly.
c) The needle case rests solidly and completely on the bearing retainer plate
assembly and is positioned to the right so the right side of the needle
case is against the socket head cap screw in the bearing retainer plate as
shown in Figure 3-33.
4. Align the 4 through holes on the upper section of the needle case with the 4
threaded holes in the bearing retainer plate assembly.
