I am copy/pasting here a post I made in another topic to get a more specific conversation going. I have a new Juki "semi-dry" machine (LU-2810) that is lubed by an oil pump underneath for the hook and lower feed, but lubed by grease and wicks on everything above the bed. Zero oil on these upper parts. None. The manual has one page about lubrication and it's basically just about how to fill the lower oil tank. There is no information about grease - like what grease, how often to re-grease, etc. (monthly, yearly?) It is seemingly "permanently lubed" north of the bed according to the manual. I come from bike shops and factory maintenance jobs. (I was also facility and equipment manager at a big screen print shop) I live by the book for maintenance but this seems like machine suicide. There must be SOME kind of recommended interval for greasing these machines? Like...the needle bar not needing oil...that's just WEIRD. Anyone have an engineer's manual for these types of Jukis? One thing I learned long ago is that if it is truly engineered for grease - DON'T oil it. Oil eventually dilutes the grease and may not supply proper lubricity for a given part. Thoughts? One thing I love is I don't really have to worry about staining at all. No need to wipe down the foot every time I start up.
I have a CB3200. When the needle is cycling around the top, and only at slower speeds, I get a distinct "click". I keep it oiled (I sometimes get oil on the leather) but it still clacks on slow speeds. Am I missing something or is this normal? It's done this since I've had it.
Ok, so I have a juki ddl 8700 machine that has an oil pan under it. My husband is an auto mechanic and wants to learn more about sewing machine mechanics, but he refers to this method of "self oiling" as "pressure lubed". I also have several other vintage singers for my leather work. The one I primarily use is a 111w155. It does not have reverse, I have trouble adjusting the stitch length, it does weird things with the lighter weight leather, etc; so I'm thinking of getting a new machine. My husband is convinced that the best way to go is a "pressure lubed" machine. Besides juki and singer I have sewed on adler, consew, and brother and would feel comfortable buying any of these. I don't remember any of the machines I've worked on being "pressure lubed" and it has never been an issue, but in searching, I haven't even found any walking foot machines that are "pressure lubed". Does anyone have any info on this? And does anyone have any reason as to why an adler, consew or brother would not be as good an idea as a juki or singer? And is there a place that has a comprehensive list of attachments for singer 111 and their applications? I have a lot more questions, but I'll stop there. Thank you, heather
