Knocking noise when sewing

Hello,
I have a problem with my machine making a knocking noise when sewing. It seems to be coming from the needle clamp. As it raises up it appears to be knocking against the plate above it. This hasn't happened before and there has been no damage done to the machine. In fact apart from this noise it seems to be sewing as normal.
Is there something I can do to remedy this problem?
Thank you.

If the machine does not knock when in straight stitch then it is the stitch width limiter. You would have to take off the side cover with a T20 torx screwdriver. Once open you will see an elongated U-shaped piece with a screw through the bottom of it (its maybe a half inch long or so). Its just above that big bottom thread guide. I think you need a T10 torx driver, loosen that screw and move that u-shaped part slightly (very slightly) so it isn't hitting anymore on the side to side action. It happens but can't really harm anything.
I'm sure thats it.

We got Juki DDL8100E. Few days ago. when sewing, needle broke and since then our machine is making heavvy noise. Also, the Stitch adjuster knob is vibrating up and down. please help


check that a bit of the broken needle is not interfering with the bobbin case movement
if the breakage was hard enough it may have altered the needle / hook timing which will cause a knocking sound as well

Why does it make a knocking noise as it sews?


the needle position is up tight in the holder and no where else
the cut away bit of the needle faces the bobbin case hook and the groove in the needle faces the end of the machine and gives clearance for the thread to pass through the material
from your description and what you did, the needle /hook timing needs adjusting as it is out
turn the machine over by hand as in sewing and watch the position of the eye of the needle and the bobbin case hook
just as the needle starts to move up, the hook should be just above the eye of the needle at the edge of the needle
The adjustment is by loosing off the screw on the vertical shaft at the end of the machine that is attached to an arm that moves the needle up and down and move that bit up or down until the needle is positioned correctly to the hook
tighten up the screw
next is to check the needle tension is not too tight
workshop manuals are available on line in pdf version or take it to a sewing machine repair shop for a proper diagnosis

A KNOCK FROM MACHINE


If the machine is making a knocking noise when stitching, the first thing to do is install a brand-new needle. Frequently, bent or damaged needles will make a horrible noise. If the noise continues, you may want to take it in for service. Could be out of time.

First thing, install a brand new needle. A bent/damaged needle will frequently make noises.

Second, if it is mechanical machine (not computerized), it most likely needs a good cleaning and oiling.

Will not zigzag or decorative stitches New to these newer plastic style...

If it continues to make a knocking noise, it could have a bent part or be out of time, in which case you should contact a service repair shop.

My machine started knocking & the lower thread jamming; how do i fix it?


have you tried a new needle
Correct needle insertion is mandatory for proper use of your sewing machine.
Raise the needle bar to the highest point, then loosen the needle clamp screw to remove the old needle.
Place the new needle in the needle clamp with the flat side of the needle facing the back, (round needle, the groove in the needle should face away from the shaft).
Push the needle all the way up as far as it will go. Then tighten the needle clamp screw.
check the bobbin to make sure it's not damaged
rethread the machine top & bobbin
clean under the needle plate & in the bobbin area for lint or threads
also make sure the top thread doesn't come off the thread take up

Singer Confidence 7463 - needle is knocking - bobbin wont thread...machine doesn't stitch - not even 2 months old


Have you changed the needle since you purchased it? A needle should be replaced every 4-6 hours of stitching so for each garment sewn as a rule of thumb. So try replacing the needle, cleaning and oiling the maachine as per the manual. Check needle is in the correct way, it is easy to put in backwards if you aren't familar with them, flat shank to the back and there is usually a scarf (cut away area) at the back of the needle which is where the rotary hook under the needle plate comes around to catch the upper thread during the stitch process. So if needle is in backwards this will cause stitching to fail.

So elimate the needle firstly.

If this fails and the knocking noise continues, then it could be that the timing has been knocked out. It can happen if you sew over a pin and hit it hard (or the needle strikes the foot if stitch setup is wrong for the foot being used). In this case, you'll need to take it back to the shop for the serviceman to fix.

Seems to be out of sync. makes a knocking sound, not catching bobbin thread.


Is the needle in facing the right way? Flat shank to the back.

The knocking sound could be your needle is bent too, have you just had a threading jam up?

I'd remove the needle plate and bobbin and threads, clean everything and oil, put in a new needle, then slowly move the flywheel manually and watch the needle action to see if you can identify where the knocking noise is coming from.

Failing that, I'd say the timing is out, take it to a serviceman. The thread's not locking is usually a good indication of this fault.
