How to remove the handwheel on a 1703 (and maybe others but not sure) To remove the handwheel on an 1703 you need to remove that light colored circle in the center of the handwheel. Take a pin or needle and put it in the tiny hole you'll find along the edge of that circle and lift off. Under it is a screw
to loosen to remove the handwheel.

Model 385.1764180. How can I loosen tight hand wheel?


Be very careful if your machine is computerized as you don't want to get oil in the electronics. These instructions are for a Mechanical Machine only!



Revised--okay, if the needle mechanism is not moving, it needs oiling too. Open the top of your machine so you can see the mechanical insides. Gently and slowly wiggle the handwheel and watch what parts move where. Using good quality sewing machine oil (not 3-in-1, WD-40, cooking oil, or the old sewing machine oil from your grandmother's sewing box), drop ONLY one to two drops of oil each spot where metal moves against metal. Do NOT oil any metal Cams, belts, or plastic gears! Oil all the moving spots across your machine including the needle bar mechanism. (If possible, you will need to open the side cover to the left of the needle bar.) The needle bar needs to be able to move up and down and most likely it is stuck or it could be the take-up lever (the parts that look like knuckles that rotate round & round to move the needle bar). (WATCH Video Part 2 below, about 1 minute after the beginning.)

Look closely for oil ports (little round holes next to joints where things move) and apply a couple drops of oil in each port. (About 1.20 minutes into Video #2, you will briefly see an oil port on the top as she is rotating the take-up lever.) Those are the oil ports you will be looking for but they will be spread throughout your machine.

While you are at it, you might as well oil the moving parts in the bobbin area too. Most likely if the needle is stuck, parts in the bobbin area are also hanging up.

Now, to make the oil work faster, direct hot air from a handheld hairdryer at the mechanical interior of the machine. Get the metal warm to hot (don't get burned). Let it cool and try your machine. See if anything has loosened up. Are things moving better? If it is but the motor is still straining, you need to repeat the process until the sewing machine has a "happy" little sound.

IN THE FUTURE, clean and oil your machine every 8-10 hours of constant sewing or every six months if not in regular use. Doing some regular maintenance will keep your machine and you happy!

This is Part 1 (of 3 parts) of oiling a mechanical machine video that may help you. The machine is older than yours, but the idea is similar:

Part 2: https://www.youtube.com/watch?v=lA0TwCK2MOY

Part 3: https://www.youtube.com/watch?v=7KChFHHG7nk

=====================

What exactly are you trying to accomplish? Is the handwheel difficult to turn (if it's a mechanical machine, it needs cleaning and oiling). This may help except you will need to concentrate of the handwheel mechanism:

Or is the handwheel not spinning freely because the belt is too tight?

Or are you unable to disengage the handwheel to wind a bobbin?

Here's a manual if you are need of one:

How to replace kenmore model 158 13400 belt


Good morning
If you have got the belt, I would remove the old one and put the new one on as the old one disappears. I used to change belts that way when I had a machine.
Enjoy your coffee

How can I fix a drop-in bobbin


  1. Cleaning and oiling the machine
    • 1 Unfasten the top, bottom, side and handwheel covers, using a screwdriver. Set the covers aside.
    • 2 Remove the plate that covers the thread bobbin. If it is screwed in place, use a screwdriver. If it is held by a clip or magnet, use a small flathead screwdriver to pry up the plate.
    • 3 Thoroughly clean inside all the openings, using a vacuum with crevice attachment. Remove any stubborn lint, and use tweezers to take out any thread that is wound around the parts.
    • 4 Clean the teeth on the gears, using the tip of a round toothpick to loosen the grime. Vacuum to remove it.
    • 5 Lubricate all the moving parts. Use white lithium grease on the gears, and sewing machine oil on the other parts.
    • 6 Reassemble the machine and plug it in.
    Tightening or replacing the drive belt
    • 1 Remove the top cover, bottom cover and handwheel cover, using a screwdriver to take out the screws.
    • 2 Inspect the drive belt. If it is slack, use your screwdriver to loosen the screws that hold the motor in place, then follow step 4, below, to increase the belt's tension. If the belt is cracked or broken, get a replacement from your sewing machine supplier.
    • 3 Install the new belt. Loosen the motor-mounting screws, and shift the motor toward the handwheel so you can slip the belt over the parts.
    • 4 Shift the motor away from the handwheel to increase the belt's tension, then tighten the motor-mounting screws and check the tension. The belt should flex no more than 1/2 inch (12 mm). If it is too loose, increase the tension.
    • 5 Reinstall the covers and plug in the machine.

The needle doesn't go up & down. Any suggestions? Thank you


Does the handwheel turn eazy or is it stiff. If it is stiff you need to take the top and bottom off and lubricate all moving parts. may take a bit of turning the handwheel and lubicating(it may tire you out). If the handwheel is not stiff I would check to see iff the motor is spining at all. If motor is not spining may be a bad footcontrol. If it is spining try cleaning the belt pullys and tighting the belt.
hope this helps

Model no. 158.17741. the belt is moving, the motor is running, but the part that goes up and down with the thread is not, the belt seems to be tight enough


Check the centre of the handwheel, there will either be A) an inner wheel or B) push/pull device to disengage the needle arm when bobbin winding....it needs to be A) tight, or B) pressed in to re-engage the clutch for sewing......your manual will probably have a diagram,
I could not find a picture of this model, so unsure of the exact mechanism, but it is in the middle of the handwheel

Singer Model 5050 Timing Problem


Actually,timing of needle vs, shuttle is not very easy job several factor you should check on.There is belt ot sometime a shafting with worm gear and helical gear under machine w/c drive the shuttle with the bobbins in timing order,Any one of them is present on the timing adjustment can be done by releasing the belt or the helical gear,besure machine is unplug then set all mechanism on low dead center meaning the needle move to utmost lower position catching this by the shuttle and bobbins at center position.No motion applied if this was set up,engage the belt with pulley and the bobbins link holder tigh allenscrew besure the needle is lower dead center at the center of shullle bobbins catching needle without motion when setting back at original position.If this was made manually move it on handwheel going up and side down the needle gradually if the needle move freely several time and it was catching this by the shuttle hook bobbins.if ok put thread bobbins and upper thread dial tension with the needle.Move machine on handwheel try to catch the bobbins thread,If this so your machine is ready to sew again if problem occurs on alignment repeat adjustment on perpect alignment,besure all parts on upper casing of machine specially two drive gear are in normal alignment.

Broken belt


If you are having problems finding the correct belt, sometimes the stretch belts work great for these situations. You can find many of them on ebay.

Old kenmore sewing machine model # 1237 ( not found in search) - prob. purch.'d in 198o's


Check the handwheel. If it is pulled out, the clutch is not engaged. Try pushing it in! (It would be really nice if the solution is this easy!)

Handwheel is stuck


NEVER force a newer model machine. Everything inside is plastic and WILL break. Remove the needle, bobbin, bobbin case, and unthread the machine. See if the handwheel turns. If it doesn't, several things could be wrong. The lower end machines won't have belts to come off, they will be fully gear driven. If it is a better machine, it might be a belt problem. Small pieces of thread could be stuck in a gear mesh somewhere. A gear could be broken. It is possible for a gear to break on the first use.
