dancingevilgenius Report post Posted January 4, 2012 I just happened to be in Toledo over New Year's so I decided to go ahead and buy a SewPro 500GR servo motor from Toledo Industrial Sewing Machines and save myself some shipping. I installed it on a Juki 5530 (don't laugh). My first priority was slowing down the speed so I can control my stitching. The gear reduction and increased torque is desired but not necessary for my current projects. Anyway, after the motor replacement I noticed that I cannot get the oil to splash in the tiny bubble window, like it used to with the clutch motor. The oilpan is full. And yes, I did try to 'burn in' the machine again by running the machine for 5 minutes, with short infrequent stops. I tried the paper oil-spray pattern test. I'm getting some spray but it is uneven droplets, not the small even spray pattern I was getting earlier with the clutch otor. I'm afraid that if the machine doesn't get proper lubrication I could break something. Help. thanks, Carlos Quote Share this post Link to post Share on other sites
Art Report post Posted January 4, 2012 I have always had a suspicion that the pumps for high speed machines don't quite preform at lower speeds. I have two self oiling machines and I oil them by hand. I also use very high performance oil on them occasionally just in case. That is just a suspicion I have had ever since they started putting pumps on sewing machines. If you run them fast there does not seem to be an oiling problem. You seem to be getting some oiling so there might not be a problem for you. A dermatologist friend told me there are only three things you can do: 1. If it is dry put oil on it. 2. If it is oily put astringent on it 3. Don't do anything, it might go away on it's own. The first one is really important for sewing machines.
