So, I was making an apron and my machine started making a clunking/thunking noise.

I did a quick search here and tried to troubleshoot the issue.

The only thing I can think of is it is bobbin case.

My machine is not a super great one... a Brother 2600i, or something to that nature.

Has anyone else had a similar problem? Just trying to figure this out.

Thanks in advance.

I have a Brother and when to much lint builds up in the bobbin case and under the feed dogs it will start making a clunking noise. Have you gone in and cleaned the bobbin case? You may have some lint build up. I use canned air to clean mine out then do a quick swipe with the brush to get rid of the lint.

Hope this helps.

I will try it again.... hopefully it will be that easy to fix.

Thanks!

could be a dull needle as well if you haven't changed it in a while

Do clean out, though I'd recommend vacuuming as you brush instead of canned air. A quiet "thunk" or "thwack" might be a dull needle, though.

Thanks....

No luck... it makes the sound without the needle in. Also re-cleaned and it still makes the sound.

HECK!

It may be that the timing is off. This can make a thunking noise if out of line.

how do you fix that? Is it a repairman type visit?

I only ask, because it was a $120 machine from Walmart about 5 yrs ago. I have only been quilting about a year and was thinking of getting a better machine. Therefore, I do not want to spend a bunch to fix this machine, if I am going to be upgrading soon.

Sigh... decisions-decisions.

I understand your pain-I am going in tomorrow to the local machine store to test drive their machines. I wasn't counting on doing this for at least another 6 months!

Some less expensive machines aren't made to be repaired.: (
It's a throw away society. Check with a local repair shop, they may not recommend repairing it.

I have several brother machines and the latest one has a plastic black case around the bobbin housing, it is the problem with mine. I was very disappointed had to buy a new machine for the same reason, price. I upgraded to a new machine. I do regular maintenance on my machines and keep this area clean.

Brothers are not easily oiled, but I do mine. Use a dime to loosen that big screw. Oil the moving parts there. It helped mine.

My friend had. Brother,same problem...it made so much noise that it sounded like it was going to explode! It's now at the dumps!!! Good luck!

I have the same machine and had that happen one time. I cleaned it, completely re threaded it (spool as well as bobbin) and put in a new needle and whatever was the problem was solved.
Make sure you're using the right kind of bobbin??? A plastic one like what came with the machine - metal is not good.

When this happens I always clean and oil, then change the needle.

I'm sorry the cleaning didn't help. Did you clean the moving parts as well as the case? Lint builds up on those to. I ended up cleaning mine yesterday after reading your post and boy did it need it.

This is a neat little tool I use to get into those difficult spots on my machines when I need to oil them. My husband got me one from his job but you can buy them and they make oiling a cinch. Some if you look around do have a longer tip.
