How to check timing on pe180d embroidery machine


In case of adjusting sewing machine timing, there are twomain parts that you should follow.To adjust the hook needle timing on the rotary hook, first,remove the bobbin, bobbin carrier, and covers so you can see the movement ofthe hook. This may involve removing the needle plate for top loadingassemblies, or removing the hook cap from the front of the machine. Itoften requires the removal of the lower covers to reach the componentparts. Adjust as needed when doing sewing machine repair.Set the machine to a straight stitch at the defaultposition. Different models have different default positions including themost common far left and center positions. If no problems are perceivedin needle bar positioning, the default position will suffice. If thereare needle bar position issues, these need to be adjusted prior to adjustingthe timing. Follow proper sewing machine repair procedures.Rotate the hand wheel toward youuntil you see the needle reach its lowest position and begin its rise. Now lookfor the point of the hook as you continue rotating the hand wheel. Thepoint of the hook should strike inside the needle scarf above the needleby about 0.5mm. Sewing machine repair is vital for smooth operations.Check to see if the hook fails topick up the thread. Double check the needle bar positioning including thehook needle spacing. If these are appropriate and the point of the needlestill fails to pick up the loop thread, proceed to adjust the timing of thehook. Maintain regular sewing machine repair. Look for the lower drivemechanism. It may be a lower shaft with gears on either end. If this isthe case, look to the right end of the shaft for a gear with adjusting setscrews. Loosen and manually adjust the position of the hook. Tightly hold thehand wheel while turning the drive shaft to set the proper position. Retighten adjusting screws. Some models have timing beltsthat control the timing of the sewing machine. Look for a belt connectedon each with to drive gears. Look for work cogs on the belt. Inmost cases, you can reset the timing belt, without replacing it. If,however, the belt requires replacement you will need to do so. Loosen the drive mechanism on the right side to free the movement of the belt.Manually adjust the position of the hook to the needle and re-tighten set screws. This knowledge is vital for effective sewing machine repair.Once the timing has been reset,conduct thorough test sewing on the sewing machine to make sure everything isworking properly.Hope this will help you. Good Luck.

I can't get my buttonholer to do anything but stitch in the same place over and over. It will not advance to make the buttonhole. I have read and read the manual and followed all instructions and still...


there is a gear inside the button holder socket.
A gear inside the buttonholer device "rides" against these edges to give you exact same size buttonholes every time! .the gear whioch spins is cracked or got misallighned so it needs readjusting or replacement.
get it done.

Bobbin drive gear


You need to get the gear from your elna dealer. To time the machine, you want the tip of the hook to pass just over the top of the eye of the needle when the needle is in the left most or right most position depending on which side the eye of the needle will be higher

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.

Singer 758 adjustments for needle position and stich width


Found this below that may help confirm timing? As for the zig zag one thought is to check for end play in the upper shaft. At the left hand end of the shaft (under the top cover) there is an white plastic "bushing" with one slotted screw - this can be adjusted to take up the slack. It is possible that this bushing is split by the screw which may make it come out of adjustment. Check the other collars on this shaft are tight (hex) - by the belt and near the drive gear. P.S. double check the zig-zag cam is in the correct position (set to straight sew - centre position to install the cam - check instructions).

Timing
Turn the handwheel towards you until the needle is in the lowest position and observe two lines on the needle bar at the place where it comes out of the machine. You have to see these lines. When you find those, you have to tilt the machine on its back and you will see that on the right hand side there is a belt coming down onto a gear like piece on the timing shaft. Move your eyes to the left and the next thing that you will see is a large round gear on the feed shaft. Now that we have determined the difference between the feed shaft and the timing shaft, follow the feed shaft to the left and there will be a small metal piece there with two metal screws on it. Next to that to the left is a stationary metal peice that has a bump on it. You must see these two things to adjust your machine.

Now, to determine if your machine is out of time, turn the handwheel towards you (always turn it towards you) until the needle is in the lowest postion again. Observe the two lines on the needle bar, turn the handwheel toward you until the bottom line goes in the exact place where the top line was. Now look at the needle and hook. The hook should be directly behind the needle. If it is not, we go back to the bottom of the machine on the gear like metal piece that the belt rides on and loosen the two screws that are in the piece. Now if you will remember, this is on the timing shaft. When these two screws are loose, the hook will become moveable. Place the tip of the hook directly behind the needle without moving the needle bar (remember that the needle bars bottom line was placed where the top line was). When you have accomplished this, tighten the screws on the belt gear.

Now you have to determine whether the feed is in time. Again, place the needle in the lowest postion, rise the low line to where the top line was, and see if the line on the feed shaft is directly next to the bump on the stationary metal piece. If not, without moving the handwheel at all (because it must stay in this position to time it), loosen the two screws on the feed shaft piece and align the two lines together. Then tighten the two screws, make a few rotations with the handwheel, and again, put the needle in its lowest position and rise the bottom line to where the top line was. Inspect the two lines on the feed shaft and the hook behind the needle.

If these did not stay in adjustment, re-do the entire process, but be more careful not to move the handwheel when making the tightening adjustment. If you re-do this and it still does not stay in adjustment, you need to replace your timing belt,
