132k6 thread jam
I've had an issue with my 132k6 for a while. The needle thread gets jammed between the hook and the "position bracket". This doesn't happen on every cycle, and sometimes it will sew fine for a while. The result is needle thread loops hanging from the bottom of the material (at any needle thread tension). So i was curious if anyone has run into this as well: (jammed.jpg, tight.jpg)
My knee jerk reaction is to just take the position bracket and/or hook to the mill/grinder: (modify.jpg)
The timing looks pretty good, but maybe the hook is a little close to the needle? When the hook tip is at 12 o'clock, it is pretty close to the middle of the scarf, but as it continues to rotate and the needle goes up farther the gap is reduced to about nothing, perhaps even light contact aft of the hook tip. So maybe a better solution would be to move the bobbin/hook assembly farther from the needle? I am unable to find a user manual for timing info (only a parts manual) and i have come to the conclusion one doesn't exist.

I actually have that manual in paper form, but didn't pay much attention to it since the B26 is a double needle drop feed, and the K6 is a single needle walking foot. But now that i think about it there's no reason the timing would be any different between the two.
I advanced the hook timing. I would guess about 20 degrees. It hasn't jammed since so i think that was the problem. Thanks for the info.
It seems to be sewing well now with the exception that the thread and/or bobbin tension(s) vary based on the locations of the loops. Without changing anything, and sewing on the same thickness material, sometimes it appears the thread tension is too high / bobbin tension too low and sometimes vice versa. It seems to randomly vary back and forth and everything in between (sometimes the tensions look balanced). Maybe i'm just being picky.
