Members the deacon Posted January 19, 2018 Author Members Report Posted January 19, 2018 Thanks Wiz. I made those adjustments, I didn't see too much change in loop tension. I also moved the spring stop per Uwe's video on adjusting the check spring tension. I think it's pretty good. I have to do some more thorough sewing to be fully sure. I did see another issue while doing all this. It has to do with the feed dog. I'll start another post so as not muddy up the valuable info here. Quote
Members the deacon Posted January 19, 2018 Author Members Report Posted January 19, 2018 One more thing. I noticed there was some play and an audible click with the finger that pulls back the bobbin switch. Are those normal tolerances? Quote
Uwe Posted January 20, 2018 Report Posted January 20, 2018 (edited) On my Juki LS-341 that bobbin case opening finger is rock solid, has no noticeable play and makes no clicking sound when pushed. Perhaps something didn't go back together quite the right way after you removed the hook. I'm also a little surprised that we have totally different hooks in our supposedly identical machines.

Members brmax Posted January 20, 2018 Members Report Posted January 20, 2018 (edited) From this last part of the discussion, I am going to assume there is some slack. This end play/slack is up and down. Its where the inner hook guide/bobbin case opening lever Plate sits in my oppinion. From looking in the 13 series parts book, this is showing a couple different hooks. Interesting hook differences and case “ hold down part”. But anyway I think importantly here in this discussion is, that the case opening lever is on a plate assembly. This is like my 1341 So keeps my interest. Also like my own a slight bit of end play or slack, this will enable the lever to move. Actually still end play, though when pushed as mentioned earlier it actually tilts ( noise/click ) the plate. This seems to move and so can be an adjustment to use some Kentucky windage when adjusting. In this I suggest adjusting to a bit more slack opening. Im hinestly going to be glad in understanding better how best to remove the end play. This may be accomplished with the different but available shims on the gear side but I’m not sure with this plate assembly. On a bit more with hook differences, I see the 1340 and 1341 differences, I suspect not much different than the 340 & 341, I do recall this different bobbin style from a long time ago ( and liked it ) but I have the cap style, maybe adler style of a sort. Have a good day there Floyd ps: respectfully to Juki mine was this way out of the box. I work with it! Edited January 20, 2018 by brmax Quote
