Timing Between Needle and Rotating Hook
Follow these steps to help get the proper timing on your machine.
Step 1:
Remove the two needle plate screws from
your machine and set the needle plate to the side.
Step 2:
Remove the two screws on the protection
cover at attach it to the face plate of the machine.
See figure 83
Step 3:
Remove the three screws holding the face
plate to the machine. Remove the face plate and set
this part aside.
Step 4:
Check the protection flange of the position
bracket (A). This should be engaged in the notch (B)
of the bobbin case holder. (D) in the drawing shows
the set screw to adjust hook timing.
See figure 84
Step 5:
Turn the hand wheel to locate the needle to
its lowest position. Note: Correct needle position is
when you can see a small portion of the eye of the
needle.
See figure 85
Step 6:
If the needle is not stopping in the correct
position, you will need to proceed to the next step. If
it is in the correct position, move to step 9.
Step 7:
Loosen needle bar connecting screw (A).
This will allow you to raise and lower the needle bar
for correct location. Note: Check all photos before
making any adjustments
See figure 86
Step 8:
Once you have the needle in the correct
location, tighten needle bar connecting screw (A) to
prevent the needle bar from moving out of position.
Adjusting rotating hook point timing with needle.
Step 9:
Turn the hand wheel counter clockwise to
locate needle to its lowest position.
Step 10:
At lowest position, turn the hand wheel to
raise the needle 2.5 mm (1/8”)
See figure 86
Step 11:
Hook point should be just above eye of the
needle.
See figure 88

Step 12:
If the hook point is in the correct
position then move to step 18. If the hook point
is past this point or not yet reached this position
then you will need to follow the next few steps
to adjust the hook so that when the hook point
reaches this position it is just above the eye of the
needle. Proceed to the next step.
Step 13:
See figure 84
for position of the three
screws (D). Loosen the three screws holding the
hook assembly to the shaft. (Note you will have to
rotate the hand wheel to get to all three screws.)
Step 14:
With the hook loose, reposition the
needle to the lowest position. Rotate the hand
wheel counter clockwise to bring the needle up
2.5mm (1/8”)
See figure 87
Step 15:
Now rotate the hook so that the point
of the hook is just at the edge of the needle.
See
figure 88
Step 16:
Lock one screw holding the hook into
this position.
Step 17:
Rock the hand wheel back and forth to
ensure that you have the hook in the right position
to pass the back of the needle just above the eye
of the needle.
Step 18:
When adjusting the rotating hook point
timing also note that clearance between notch
bottom of needle (D) and hook point (C) must be
maintained. HOOK CAN NOT RUB AGAINST
NEEDLE.
Step 19:
Once you feel like everything is in the
right place tighten all screws you loosened.
Step 20:
Return all covers and screws back into
place on your machine.
