Check the Left-Right Positioning of the Shuttle Gib Hook
If the shuttle assembly and lower shaft have slipped left or right of the factory setting, the Shuttle
Gib Hook will not be in position to catch the thread loop� Fortunately, this is an adjustment that rarely
requires attention�
1� If not already, install the gib hook (p� 30,
M
)�
2� Make sure you have a #20 needle installed�
3� Remove the needle plate (p� 49,
17
) and feed dog (p� 55,
18
)�
4� Looking from the top down into the machine (
49
), slowly rotate the balance wheel� As the gib hook
(
A
) swings past the needle, the hook should be as close as possible to the right side of the needle
without deflecting it (
B
)�
If the gap between the needle and the hook is too large, the hook must be moved to the
left to close the gap� See p� 45 to make adjustment�
If the needle is being deflected by the hook, then the hook must be moved to the right.
See p� 45 to make adjustment�

For the sake of clarity, (
49
) shows the machine without the retaining ring installed� While this makes
it easier to see the timing, the hook must be held in place with light finger pressure to keep it from
falling out of the shuttle assembly when rotating the balance wheel�
