Timing A Mechanical Sewing Machine

If the thread is not being picked up by the hook, you can set your timing by moving the needle bar height. move the hook so it is in the nearest position to the needle, but not touching. Remove the left, needle bar cover. You'll see a screw, or set screw on the needle bar. Slowly loosen it, and move the needle bar up or down until the hook lines up with the scarf on the back of the needle. The tip of the hook should be in the middle of the scarf, above the eye. Hold still, and re-tighten the screw.

Needle will not pick up bobbin thread


could be the bobbin thread tension is too tight or not out long enough to move around the case
could ne needle and hook timing where the needle and the hook are not in the correct place for the hook to pick up the needle thread
could be the needle in installed incorrectly so the cut away section is not in place to enable the hook to pick up the thread
If you have broken a needle just before the problem it could be the timing has moved and needs resetting
If none of these work for you, take it in to any service shop and have it properly diagnosed

how to set timing and bobbin in my juki ddl-555


hi there
when you need to set timing please first make sure height of needle bar is ok. there's two mark at needle bar, the upper one is for height of needle bar: bring the needle bar at lowest position and in this case the upper mark must be equal with lower needle bar bushing.
second : set timing
move hand machine pulley at the same rotation and when the lower mark equal with lower needle bar pushing the tip of hook must be at the center of needle groove and just light touch not hit. that's all

Singer Model 6233 While sewing the bobbin cas...


If you broke a needle and cannot get it to pick up the thread from the bobbin you need to check your timing. Remove the needle plate and turn the machine over watching the needle, when it is at the bottom of its travel the hook on the shuttle should be right next to or a fraction from the needle. So that as the needle begins to move upward the hook should pass it if it passes to soon it will miss the loop of thread. Check to make sure your needle is installed all the way up in the bar. If your machine is out of time and you are fairly handy, you can retime it. There should be 2 set screws some where behind the shuttle. Loosen them, one loose and one only as loose as need be to turn the shuttle. The needle must have moved upward about 1/16 before the hook is in place to catch the loop. This can be time comsuming, and you will have trial and error. Good luck. P.S. always check for simple stuff before you go for the hard stuff.

my CE 200 jammed and I cleaned it out now it won't pick up bobbin thread how do i reset the timing?


To reset the timing on your machine there are timing marks that show you where the machine must be set.
Remove the needle plate and bobbin case. Turn the hand wheel towards you until the needle bar is in the lowest position. You will see two marks on the needle bar with the top one being flush with the bottom of the bushing. If it is not, loosen the needle bar screw and move it up or down to set the marks. Make sure you keep the needle bar straight (needle clamp screw should be straight to the right).
Next turn the hand wheel until the lower timing mark is flush with the bushing. At this point, the hook tip should be just above the eye of the needle.
If the hook tip and needle do not line up, turn the machine on its back making sure the needle bar does not move. Loosen the two timing screws on the hook pulley (only loosen them 1/4 turn). Move the hook to line it up with the needle. Tighten the screws and recheck the timing. The feed dogs should be in the down position when timing the machine. If the feed dogs are up when the timing is done, the hook timing is out 180 degrees.

Timing is off on my Pfaff 2140/2170 machine.


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
hook.
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.
