Question about Sewing Machines

1 Answer

Timing is off on my Pfaff 2140/2170 machine.

If I could get detailed directions with diagrams, I could fix my machine. I was sewing the other day and the needle came down on one of the pins in my fabric, thus causing the message, "main motor blocked". I cleared out the broken needle and tangled thread, and tried to resume sewing. It would not sew stitches correctly. That is when I removed everyting I could to see inside where the bobbin hook passes the needle. They were WAY off. The nearest service center is over an hour away, and I don't have the time or money. I planned to make lace covers for ornaments to give as gifts this year. Please help.

    Now, if I had a diagram of my machine showing me exactly where the set screws are and the gears I would be set. Thank you for your directions. I did find them helpful, but I need the extra step of diagrams.

Basically on any sewing machine to time it you will need to separate the two gears that drive the hook. Usually loosen the set screws that attach the gear to the shaft and separate them.
Time the hook first. On center needle position, set the hook so that the point is behind the needle when the needle bar has risen about 2.5mm.
2) Set the needle bar height. Choose the needle position which is the last for the hook to pass.
(Left on most machines, right on older Vikings) At this point, place the point of the hook behind
the needle and set the needle bar height so that top of the eye is just barely below the tip of the
3) Check feed timing. Set the stitch length to the longest stitch. The needle should enter the
fabric just as the teeth drop below the surface of the plate.

Timing PFAFF 1222SE timing

Have you tried a brand new needle and checked to make sure it is the correct needle and installed facing the proper direction? If you've done all that, then it is most likely a needle/hook timing issue. Probably need to take it for service.

How do you reset timing on Pfaff Creative 7570 Machine? Was sewing and heard loud pop, now will not work. Any ideas?

Hi Lisa,
"A loud pop" whilst sewing sounds as though a capacitor has blown probably in the power supply unit. I'd recommend that you take your machine to a Pfaff service shop to have it serviced.
To reset the timing on a sewing machine is a specialist job. To give you an idea of what it entails on a mechanical machine (your machine is electromechanical) have a look at this video
Good luck :)

How do you adjust timing on pfaff 138 sewing machine

Take the foot off the machine
Remove the needle plate
Remove the feed dogs
rotate by hand until the needle is at the lowest position
continue rotating until the needle rises 2 mm
the hook assembly should be passing exactly by the scarf of the needle
if not loosen the two screws that secure the the hook assembly and rotate the hook assembly by hand until it is exactly at the scarf of the needle and the distance between the hook and the scarf is .1 mm (almost touching the needle)
tightened the two screws, replace the feed dogs and foot and it should sew perfectly
