Adjusting the Left-Right Positioning of the Shuttle Gib Hook
1. Set the machine to straight stitch and place needle in
center position.
4. Carefully move the assembly to position the hook as
close to the needle as possible without deflecting (E).
2. Make a mark (A) on the shuttle race guide shaft where
the halves of the compressible clamp meet (B). If the
shaft should accidentally rotate, realign the mark with
the clamp gap.
5. With the mark on the shuttle race guide shaft (A) and
where the halves of the compressible clamp meet (B)
aligned, tighten screw (C).
3. Incrementally loosen screw (C) until light taps will
move the shuttle assembly (D) in either direction.
After adjusting/verifying the correct left-right position of the shuttle gib hook, proceed to check the rotational
positioning of the shuttle race guide shaft (p. 53).
