Replacing the Take-Up Spring
(#533211)
If you are getting inconsistent stitch tension or if your thread looks loose and sloppy near the tension assembly under
operation, check your take-up spring (H ). If the wire hook has broken off, you’ll need to replace the take-up spring. To do
this, disassemble the Upper Tension Assembly. Keep track of how the parts are removed as they will be replaced in the
same manner (49).
1. Pull the cover knob (A ) straight off (wiggle a bit if
needed).
2. Unscrew and remove the threaded
knob (B ).
3. Remove the big spring (C ), the spring holder (D ), the
two tension disks (E and F ), and the keyway washer
with pip (G ).
4. Remove the old take-up spring (H ) by pulling it straight
out.
5. Slide the new take-up spring over the core post
(I ) so that the pip on the back faces in toward the
machine and the straight arm of the spring faces down
(approximately at a 6 o’clock position). Push the spring
in all the way.
6. Spin the arm of the spring clockwise past the slot in
the plastic core.

7. While holding the spring arm in place, slide the
keyway washer (G ) back onto the core with the pip
facing in, so the take-up spring arm rests on the metal
pip of the washer.
8. Replace the first tension disk (F ) with the convex side
facing out. Add the second tension disk (E ) with the
concave side facing out.
9. Replace the spring holder (D ) with the concave side
facing out and the spring (C ). Screw the threaded
knob (B ) back on the post and add the cover knob (A ).
