Help! With Singer 251-6 Industrial Sewing Machine Re: Self Oiling Pump

[mamasew]

Hi All,

I am a newbie and just purchased my first industrial machine from a charity. I found the manual on line and cleaned, adjusted, and added new oil. I turned it on and did not see oil in the window after 2 mins, so I turned it off. I took the screen off the oil pump to make sure it wasn't dirty or filled with lint. It was fine so I reinstalled.

Also, I checked the impeller and it does turn with manually turning the hand wheel. Could I have a clog in a pipe somewhere? Should I replace the oil pump? Or the wicks? Any help would be greatly appreciated since the nearest Singer dealer is far away from me.

Thank you

I also have a 251-6. As far as the oil question, I'm not sure, you've already done everything I would've tried. But I am curious where you were able to find the service manual for this model? All I can find is the parts list. I did find the manual for the 251-1,2 and 3 but there seems to be several differences mainly with the timing adjustments.
