Question about Juki Sewing Machines

My Juki 8700 is spraying oil from between the belt and handwheel. I checked the oil level and it's fine. What could be the problem?

    I would imagine that you moved your machine and oil soaked into the belt. There may also be oil pooled in the belt cover that is attached to your motor. Unscrew the two screws that hold the belt cover onto the motor and wipe it clean. Before you put it back on, slowly rotate your hand wheel and dry your belt with a rag soaked with Windex or alcohol. Sew on it before you put it back together to make sure its fixed.

    I haven't moved it but I did take the wheel off and found there was thread wrapped around. I removed it and it is no longer spraying but still leaking. I will check the belt cover next! Thanks for your help, I will let you know if it works.

  • Shirley Neibarger Sep 04, 2017

    Yeah!! Good job! Other than Windex or alcohol, if you'd rather, you can try to dry your belt with a dry rag or wash it with dish soap(Dawn) and rinse and dry. If the belt is soaked with oil, it will continue to throw oil for a while. Not problematic to the machine but very irritating to you and possibly would get oil on your project. :)

    PS Sometimes thread will also accumulate under the belt where it goes around the shaft that holds the handwheel. You might check that.

Did you move your machine? It sounds like your belt has soaked up oil. You need to take your belt off and either wash it with some dish soap, dry it and put it back on or at least take a towel and keep wiping it down until you aren't getting any oil on the towel. There is possibly oil in the belt guard down by the pulley but it doesn't usually hold enough to keep throwing it out. Also see if there might be thread wrapped around between the handwheel and the machine. If thread accidentally gets wrapped around there, it can absorb enough oil when you move it, to keep throwing it out. Good Luck

Hi and welcome to FixYa, I am Kelly.
This is a self-oiling industrial sewing machine that uses a reservior in the bottom of the unit for lubrication. There is a sight gage on the lower left side of the unit in the base that once filled with oil you will see the oil splashing as the machine operates. Since this is a new machine you fill the lower reservoir to the High mark on the sight gage and then operate it a 3000 Rpm for 10 minutes to do the initial self lubrication. Instructions are in section 6 of the users manual. The main unit is tilted on the base to service the oil in the lower reservior. They don't bother telling you that once the unit base is installed in the sewing console that you should then fill it with oil before installing the main unit on the base.

This link should download your users manual so you can read it on the computer. See page 3:

Juki DDL-8700 wheel not turning. Initially running fine, after a few minutes, wheel seizes. Machine is oiled, and we can see oil in the viewing window, Machine looks very clean inside. Motor sounds


Have you tried cleaning it? Sometimes a piece of thread or some fuzz gets in between the parts and causes friction. If you have a manual, or can get one online, you should walk through the pages on cleaning and do each and every part of the cleaning. If that doesn't work, call a professional. There are service people who come out to your shop and work on industrial machines. Mine charges $55, plus parts if needed.

How do I stop my Juki DDL-8700 machine from skipping stitches?


set up on quilting table? wheres the oil pan?? if your machine sews fine straight and skips on curves i think you are lifting the presser ft as you make the turn. theres nothing wrong with the machine. you could always change the needle which is always the first thing when you encounter a sewing problem.

I just brought home a Juki 8700. The needle went down and now I can't get it basck up. There is thread stuck in the bobbin. How do I get the bobbin casing off


Cut the thread above the needle eye and rock the handwheel back and forth sharply to cut the thread with the sewing hook. If that doesn't work pretty promptly, undo the needle clamp and turn the handwheel, which should raise the needle bar. Then get into the bobbin case area and try to remove the bobbin case, cutting any threads you can. Keep rocking the handwheel and trying to pull out the needle (pliers help!), and eventually everything will loosen up.

Next, clean and lubricate the area under the needle plate and the shuttle, and reassemble. Put in a brand new needle, right way around and fully up in the machine. Load the bobbin case with a well-wound bobbin, and rethread the top of the machine and you should be good to go.
