I forgot to turn on my thread detection after doing a WD40 clean up on my bobbin area and now have a mess I need to know if I can fix myself - I'm not afraid of taking things apart if I have clear instructions. Thread wrapped itself all around the thread feed parts and I have managed to get it all out except one area. The white gear directly behind the thread feed gear with the yellow rubber on it is the place I'm having a problem. It has an integral hub on the right side of it that I've cleared of thread, but some thread has tangled in the crevice between the hub and the black plastic housing. I assume there is some kind of shaft that runs through these gears and that is what the thread is wrapped around. Again, its not the yellow thread feed gear, but the one behind it. Any help would be greatly appreciated because right now needle #4 is in retirement.

If this is the white gear hidden behind the black cover with the small grove in it that the thread has to fit into....pop the black plastic housing off and take the gear out. It's part of the maintenance you ahve to do at ... 4million???... stitches, where you grease the hub and check the roller for grooves. Check your maintenance procedures for how to get it off, get the gear out, cleaned out, greased up, back in, and back on. -
Judy, unfortunately that was the easy one to clean up. The problem is with the gear directly behind behind the one that can be popped out.

Mama,
Unfortunately there is no easy way for the kind of mess you have described. The best way I have found, other than taking apart the whole threadfeed assembly which, unless you have tech training under your belt, I would not recommend, is by using a #11 Xacto blade turned upside down and scrubing the tread out of the axle shaft area. It takes time but it does work....Xacto knife and tweasers....flashlite and time....

If you move the active needle to #16 the gear your refering to will be exposed on the right side of the needle case from the back.
and If you remove the rubber thread roller for Needle 4 you expose both sides of the gear. then carfully snip and pull threads a bit at a time to remove them. you can push the gear up from the front to rotate whic will click but not damage it.
it should give you tha access to get the thread out.
If you need to remove the three screws holding the thread feed cover on from the right side it may give you more access.
Good luck.Comment

Also Form the back of the needle case when your looking at the rollers if you push the little read tab in above the gear #4 you will find the roller will move freely while it is pushed in both directions without clicking.Comment

Thank you Rod and Jerome. I had already done a bit of exacto/tweezer/flashlight work on it. Now I've tried scrubbing away at the crevice, but there is still some thread jammed down in there and I have a feeling its the best I can do without tech training. The gear now spins but not as freely as the others; I'm assuming this added resistance will put added stress on any motor(s) involved so I'm going to save needle #4 as my needle of last resort.
One last question - I have not run across a lubrication procedure for these gears. Do I need to use the same lubricant as that used on the other plastic parts?Comment

Mama,
Yes use the Poly lubricant.
You need to keep working at getting that thread out of the hub area. You will have to work from both the front and the back. Have someone depress and hold in the little red locking tab so the gear can turn freely in both directions. You can then concentrate on using the Xacto knife and tweasers to scrub and pick at the tread. Yes, I know it's a pain, but by turning the gear forward and backward and spinning it , you will get it out of there..... don't give up..I have had to do this many times over the years.... ;-(

I have also used waxed dental floss with some success. it can pull end out so you can get ahold of them.
I am not a fan of the exacto knife due to the fact it makes many little pieces rather then, (Though it is pains taking)- just finding the end and slowly pull then unwind front, back, front ,back, ect....
Too late for that wisdom now sorry.
But it sounds like your getting there.

Not used but USE that would be recycling to a extreem !!

I did spend an hour scrubbing and picking. I think using floss and getting someone to spin the gear for me are the next step. Thanks for your advice.Comment
