I've never had a main shaft out...is that straightforward to do? $75.00 w/shpg.the shaft can be hard to get out you need to sand it lightly as it gets rust & dirt on it.Then oil it so it slides out easier.

A few hours sitting with a few drops of diesel made a difference! I'm gonna throw away my penetrating oil 😜 I've got 2.5 turns each way now. How many turns should I expect when it's fully loosened up? Quote friquant. Like a frequent, piquant flyer. Check out my blog: Choosing a Motor for your Industrial Sewing Machine

I'm gonna throw away my penetrating oil 😜 I'm glad the you got it freed up. As far as I'm concerned there's nothing better then good old fashion Diesel. It works better then any of the "penetrating oils" just smells a bit. I would now flush/soak the area with synthetic transmission fluid. That will soak in and flush out the old garbage while lubing. Sorry, can't help with the amount of movement you should have. kgg Edited August 20 by kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver
Contributing Member friquant Posted 4 hours ago Author Contributing Member Report Posted 4 hours ago It's getting better! When I got the machine it stitched 8mm stitches. After the first round of diesel it was adjustable from 8mm - 12mm. I'm guessing that 12mm is the maximum for this machine since it seems to come to hard stop there, and it's a "round number". A week or so later I tried again and now it adjusts down to 6mm! Guess I'll keep soaking it as I use it to see if it will keep freeing up. If I can get it down to 3mm that's probably good enough. I appreciate the help Quote friquant. Like a frequent, piquant flyer. Check out my blog: Choosing a Motor for your Industrial Sewing Machine
