Adjusting the Left-Right Positioning of the Shuttle Gib Hook
Make a mark on the Shuttle Race Guide Shaft (A) where the halves of the compressible clamp meet
(B). If the shaft should accidentally rotate, realign the mark with the clamp gap.
To move the hook closer to
the needle:
1. Incrementally loosen screw (C) until light
taps will move the shuttle assembly.
Carefully move the shuttle assembly (D) to
the left.
2. Move the assembly (D) to position the
hook as close to the needle (E) as possible
without deflecting the needle (52).
3. With the clamp gap (B) and reference
mark on the Shuttle Race Guide Shaft (A)
aligned, hold the clamp (F) to the far left
firmly against the cast iron foot and tighten
its screw (C).
4. Holding the shuttle assembly (D) in place,
loosen the right collar (G) and move it as
far right as possible, just resting on the
frame. Tighten the two collar screws. There
should be practically no side-to-side play in
the center shaft (H).
To move the hook away from
the needle:
2. Loosen the two screws in the right collar
(G) and move it to the left on its shaft and
move the shuttle assembly (D) to the right.
3. Move the assembly (D) to position the
hook as close to the needle (E) as possible
without deflecting the needle (52).
4. Holding the correct position of the shaft,
move the right collar (G) as far right as
possible, just resting on the frame, and
tighten its screws.
5. Holding the shuttle assembly (D) in place,
loosen screw (C) and move the clamp (F) all
the way to the left against the cast iron foot.
6. With the clamp gap (B) and reference mark
(A) aligned, tighten the clamp screw (C).
There should be practically no side-to-side
play in the shaft (H).
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. 47).
