Removal:
Replacement:
1. Remove the free-arm extension table, al the covers, needle bar, face plate mounting
bracket, needle threadr, needle bar vibrating bracket, the stitch lenght and
buttonhole control assembly, the thread take-up assembly, the disc stack shaft gear
and bracket assembly, and the handwheel.
2. Remove horizontal arm shaft sufficiently to clear vertical shaft bevel gear (A).
3. Rotate vertical shaft (C) until vertical gear set screw (B) is accessible.
4. Loosen set screw (B) to remove gear (A).
1. Replace these parts the same way as described above, but in a reverse order.
2. Check for vertical shaft end play and adjust if necessary. (See pages 68-69).
3. Locate gear (A) so the top of the gear hub is even with the top of the vertical shaft (C).
4. Locate arm shaft bevel gear (D) on the horizontal arm shaft. (See pages 70-71 for
bevel gear mesh and arm shaft end play).
5. Position arm shaft bevel gear (A) and (D) so that the mark (G) on the gear (D)
straddles the marks (F) on the gear (A).
6. Lightly move bevel gear (D) to the left until it just touches vertical shaft gear (A).
7. Tighten bevel gear set screw (E) making sure it is correctly located in the "V" shaped
groove in the horizontal arm shaft (L).
8. Rotate the horizontal arm shaft (L) slowly several times. Observe the position of the
two gears with relation to each other. The top edges of the gears should be even with
each other (illustration M). If this condition does not exist, it will be necessary to
repeat the above procedure and move the vertical bevel gear (A) up or down in order
to achieve the correct position.
9. Adjust camstack radial play, take-up lever and needle bar connecting link lost motion,
pendulum timing, needle location left-to-right and needle to hook relationship. (See
pages 74-75 or 78-79, 80-81 and 86-87).
10. Check and adjust, if necessary:
Needle bar height (pages 84-85).
Left-right needle position (pages 92-93).
Zigzag lever bight stops (pages 98-99).
Presser bar height and alignment (pages 106-107).
