[QUOTE=Mickey2;8196695You can take the cam stack out when cleaning, it's a bit easier to check the oil points and move parts up and down manually when they are out. Another thing is the area behind the face plate where the needle bar moves up and down, if it's gummed up it can take a bit of effort to flush things out and to get things moving freely again. A good way about it is to have the machine out on a table in a heated room, go over all the points the next few days, work a bit on it now and then. The problem spot will show it self sooner rather than later.[/QUOTE]
I've got her in front of the heat register to see about loosening up some of the old grease. I don't know if my mechanical ability is up to the task of disassembly and reassembly. I took off the top and my eyes got big. I know the 401 is a serious machine with lots of stitch capability, but seeing that was intimidating. I did just find several YouTube videos on servicing the 401, so that may give me the boost in confidence I need to tackle the job.
Thanks for the vote of confidence.
