SOURCE: Replacing broken gears on Singer Touch & Sew Model 648

Remove the plastic faceplate from the front of the machine. There is a Singer logo button that you will have to pop out to release it, and then the lever nobs to get around to get it off. You can then access the allen screw on the top gear.
Remove all the set screws on both the top and bottom gears on the vertical shaft. Put them in a safe place.
The vertical shaft sits directly below the horizontal shaft, but there is some space between them and wiggle room to do the following. If the shaft does not slip down easily, use a small diameter rod or screwdriver to gently tap the vertical shaft downward until the top gear slips off the end. Remove the gear.

loosen the screw on the larger of the two feed gears (not bevel gears). Retigten so that the feed teeth start to rise right when the needle starts to rise and fall right when the needle starts to go into the fabric. Make the setting the same. i.e. when the feed teeth start to rise, how high is the needle (2mm, 3mm, etc.)? set the feed timing so the teeth rise and fall with the needle at the same height going in and coming out, this assures that the fabric only feeds when the needle is out of the fabric.

I have an old Singer 478 and I can't get the needle to grab the bobber thread. Is there a special trick for this one?


When you turn the handwheel, does the hook move? If not the top gear on the vertical shaft is stripped and needs to be replaced.
