Suggest you pull out the motor and run it outside the machine. I think you will find that any objectionable noise is originating there. If that turns out to be the case, oil the top bearing where the shaft enters the motor housing just below the worm gear. Remove one of the screws from the bottom of the motor housing and put a drop or two of oil in the lower bearing where the shaft enters the bearing. Run the motor full speed for a minute or two to work in the lubricant and see if the sound level decreases considerably. After reinstalling the motor, put grease (not oil) on the set of gears in the upper section and the two sets of gears in the lower section. -EdAnonymoushttps://www.blogger.com/profile/06057276731453019090noreply@blogger.comtag:blogger.com,1999:blog-26975001.post-66100006206340938612016-06-28T14:26:05.241-04:002016-06-28T14:26:05.241-04:00The Singer 401A I am using sat unused for a very l...The Singer 401A I am using sat unused for a very long time. Maybe the gear noise will soften with more grease and use. I've read great things about the 400 and 500 series Singer machines. In my limited experience so far with my Singer 401A I'm partial to my belt driven Singer machines. They are smoother and quieter. What do you prefer gear driven or belt driven Singers?Jonathanhttps://www.blogger.com/profile/07691465477338113897noreply@blogger.comtag:blogger.com,1999:blog-26975001.post-63278959620524636782016-06-28T13:55:27.403-04:002016-06-28T13:55:27.403-04:00I don't own a Singer 403 but they are handsome...I don't own a Singer 403 but they are handsome machines. I've done a majority of my sewing on belt driven machines. I greased and oiled up a Singer 401A recently. Nice machine but the gear noise was more noticeable than I expected. Does the gear noise on these machines bother you? Jonathanhttps://www.blogger.com/profile/07691465477338113897noreply@blogger.com
