Members farmersracer Posted October 18, 2024 Members Report Posted October 18, 2024 Hello all:) Just started to restore a singer 31-32 for some leather work. I have noticed a small friction noice from the needle bar roller bushing. Is this ok? This is my first experience with a singer 31, so I don't really know how silent the machine can be. I have made two films. One with the roller bushing, and one with the bushing removed. With the bushing removed the head of the machine is almost totally quiet. Any idéas on how to fix this - or is this not a problem at all? I can live with the sound if the machine can take it. Thankyou. Quote

I would look at the roller bushing and if it has no signs of uneven wear I would reinstall it then I would coat it with some synthetic oil and see if the noise is goes away. If it goes away you know to oil / grease it more often. kgg Quote
Members farmersracer Posted October 18, 2024 Author Members Report Posted October 18, 2024 Thanks kgg The bushing is fully oiled in the films. Bright as a mirror and shiny. I can spot a small edge in the slot where the bushing is running. I think I will try to make a small bevel at the end of the roller. In that way it will not make contact with the edge in the corner. The slot is polished and the roller is turning freely when the machine is running. I can not see any other area where the sound might come from. Any idéas? Quote

I would first try and cleanup the spot in the slot and put a drop of oil in the slot to see if the noise goes away. I wouldn't try and bevel the bushing as yet. kgg Quote
Members farmersracer Posted October 18, 2024 Author Members Report Posted October 18, 2024 Hello Slott and bushing oiled - still friction sound as in the videos. Will a 31 be silent in the machine head? Or does it always make these sounds more or less? Does anyone know... The clicking is from the hook. Quote

Members Constabulary Posted October 19, 2024 Members Report Posted October 19, 2024 (edited) just checked the 31k Parts list. Is this roller 1904 probably missing? https://www.college-sewing.co.uk/1904-roller-for-nbar-con-stud-singer.html Edited October 19, 2024 by Constabulary Quote
