Repair Q & A


Q. My Featherweight runs sluggishly. It has recently been cleaned and oiled. Any ideas?

A. Four suggestions:

1. Check for old pieces of thread from previous thread jams wrapped around the hook shaft. At this writing, of the last 81 Singer Featherweights that we have serviced at our shop, 67 have had thread wrapped around the hook shaft. In a complete overhaul, removing this old thread can cause as much improvement in performance as every other step combined.

2. If that doesn’t fix the problem, I would suggest removing the belt to check that the motor is running strongly with no load. Motor brushes may need cleaning or replacement, or the motor may need to be greased.

3. The horizontal arm shaft may need adjustment.

4. The hook shaft may need adjustment.

Q. My Featherweight is noisy. It has been cleaned and oiled and I am using a new needle that is properly inserted. What is the probable cause?

A. Five possibilities:

1. Excessive end play in hook driving shaft.

2. Throat plate is incorrectly seated.

3. Excessive end play in horizontal arm shaft.

4. The feed dog is striking slots in the throat plate.

5. Excessive end play in feed shafts.

Q. I am having a lot of general handling difficulties with different types of fabric with my Featherweight. To name a couple, my thread keeps snagging and I often get skipped stitches. I am certain the needle is not inserted backwards. Any other suggestions?

A. Four likely culprits:

1. Check the position of the hook to or from the needle.

2. Pressure or tension settings need adjustment.

3. Incorrect needle bar height.

4. Hook timing needs adjustment.

Q. The needle is striking the presser foot. Any ideas?

A. Five possibilities come to mind:

1. Needle bar height needs adjustment.

2. Needle is incorrectly seated in needle bar.

3. Presser foot is incorrectly seated on presser bar.

4. Presser bar height needs adjustment.

5. The needle is bent.

Q. The needle is striking the sewing hook. What is the likely cause?

A. Five possible causes:

1. The needle is incorrectly seated in the needle bar.

2. The needle or needle bar is bent.

3. Hook timing needs adjustment.

4. The needle clamping screw is loose.
