You more than likely will!

How is your 401 doing?
I am sure it will free up and run smooth again. There is always a machine that needs extra effort to free up and much the best method is to take the machine into regular use. If it can't be used quite yet, keep it on a table; detect all (!!!) oil points, go over them every day for the next week or two, a drop or three every where. Take off all covers, lids, faceplate, oil all hinges, joints, gears, anything were metal goes against metal. I don't use the very goey grease, find the soft smooth type, and you can even add a single drop onto the greased gears to thin it out. That is the only point not to oil every day. Sew a few minutes on it once or twice a day. Move levers, test sew the zigzag, the various stitch patterns, etc.


Keep wiping off joints and grooves as you go about oiling the next week or two. Take out the bobbin case, scrape all corners and grooves you can detect down there with a wooden tooth pick. On a 201 I had to take off the a hand wheel entirely, smear oil on all surfaces, inside the wheel as well as the rod thing it slides back on, including stop motion part. It had to be repeated again a few weeks later, after that it never froze up again. I never could detect any particular issue other than not turning smoothly, the stop motion screw not entirely freeing up the needle bar. I think part of the trouble is old oil and grime starts to dissolve as we start to oil and clean, it runs smoothly for a bit and goes sticky again until all the old oil has dissolved and been replaced. It takes a few oiling and whipe-off sessions to get there.

Best of luck ;- )
