Singer 153W 100 Needle and Foot Timing

Recommended Posts

One of these days I will get this right. I was working on getting the needle timing right on my machine and after a few tries I got in right on the money I noticed I now have the timing for the foot movement messed up.I loosened the three set screws that lock the beveled gear in place and slid it back so the bobbin assembly moved freely. I loosen the two screws that held the bobbin assembly in place then I adjusted assembly so it to the right spacing between the needle and the pickup point. After I had the right spacing I tightened the two bobbin assemble screws from the bottom and moved the beveled gear back in place and tightened it up.   When I was turning the machine by hand the needle timing and spacing were great but it appeared the presser foot motion was wrong. The needle was entering the front of the hole in the presser foot and exiting the back. The way I remember it is the needle entered the back and exited the front. I see on the spline that the oval bearing that makes it move back and forth has a groove that it locks into so it can't be adjusted. On the other end of the shaft is a bar that moves back and forth (image00004.jpg) and has a set screw but I not sure what that will change. Can anyone help me get the presser foot and needle back in time I would greatly appreciate it.

Well I think I figured it out. The oval bushing in the 1st pic has two holes. One is for the screw that goes into the slot and the other is just a set screw. They are booth the same thread and when I took off everything to clean and oil it I had put the set screw in the wrong hole and thus the timing was off.

Is the feed and foot action back in sync now?

I believe so. The foot is raising at the front and dropping as it gets to the back. Had to loosen and adjust the large screw you see in the middle of the last picture to get it were it wasn't jamming against the plate as it began and ended its arc. From what I figured that arm if somehow connected to the stitch length so I set it to the largest stitch and then made the adjustments. Not sure if I am right but it is working on the test pieces I have tried. Could find anything written about how to adjust it so I did the best I knew how.
