38. Attach the base plate using the three screws.
39. Attach the power supply unit assembly using the two screws, and insert the inlet connector.
40. While attaching the timing belt, assembly the lower shaft assembly using the metal presser and screw.
41. Position the outer rotary hook and three spacers with the lower shaft assembly (refer to following illustrations),
and attach using the screw.
42. Attach the FPM holder assembly using the two screws.
43. Attach the horizontal feed shaft bracket using the screw, and attach the horizontal feed assembly using the
metal presser and screw.
44. Insert the shaft of the feed rod into the feed block, and catch the two feed rod tension springs.
45. Attach the tension pulley holder using the screw.
46. Attach the N.P. board assembly using the screw.
47. Insert the timing belt over the upper shaft and attach using the metal presser and two screws.
Assembly Points
40. Install the lower shaft assembly with the hole (A) in the lower shaft eccentric metal facing toward the front of
the sewing machine and the notch (B) facing upward.
40. After installing the lower shaft, check that it moves smoothly. If its movement is not smooth, lightly tap the
bushing presser with a punch, then check the movement again.
40. Install the outer rotary hook with the lower shaft reference hole (C) in the thread cutter cam and the outer
rotary hook baseline (D) facing toward the front of the sewing machine.
41. * Install the rotary shaft washer with the thicker side facing upward.
41. * Adjust the outer rotary hook and lower shaft play (rotating direction clearance of the outer rotary hook) by
adjusting the position of the hole in the eccentric metal. Moving the hole downward decreases the play.
Although the ideal position is facing forward, if there is an unusually large play, adjust the position in order to
prevent the rotary hook from generating an irregular noise.
42. The screw (E) used to install the top of the FPM holder should have a screw of 14 mm.
42. Install a spacer (poly washer) on the right side of the feed adjusting assembly.
42. Press the left side of the FPM holder assembly until the feed adjusting assembly does not shake, then tighten
the screw. Do not apply pressure to the holder when tightening the other screw. After installing the holder,
check the operation and clearance of the feed adjusting assembly.
43. The screw (I) used to install the left side of the horizontal feed shaft should have a screw of 14 mm.
43. Attach the parts with the drop knob moved to the right side.
43. Check that the feed bar moves forward and backward smoothly.
* If the feed bar does not operate smoothly, an incorrect feed pitch may be produced, or an incorrect forward
and backward motion of the feed bar may be produced.
44. Install the feed block with the "S" mark facing toward the inside of the sewing machine (feed rod side).
44. Attach the feed rod supporting plate spring ((44)-1.) to the feed rod supporting plate.
45. After the tension pulley assembly is installed, adjust the tension of the timing belt. (Refer to (H).)
47. When installing the upper shaft, attach the two feed rod tension springs (44) after install the timing belt and
inserting the feed adjusting shaft into the feed regulator slide block.
* After installation, adjust the rotating torque of the upper shaft.
47. To install the timing belt, align the lower shaft reference hole (C) with the lower shaft baseline (F) and move
the notch (G) in the horizontal feed cam so that it faces toward the front of the sewing machine, then install the
timing belt.
