We've removed the bobbin case in the last entry, revealing the bare hook assembly beneath. As you can see in the photo, the area underneath the hook assembly is filthy. We've got the bobbin case off, so we might as well remove the hook assembly to clean down there. We only need to remove one screw, that big one in the center.
This screw is a rare case where a B-Square bit (#10 3/8) fits perfectly, and a Brownells bit (#360-4) is workable but not a perfect fit. If you have the Chapman screwdriver set, the bit labeled "98" is likewise just a passable fit, not perfect. (UPDATE: On one of my 201s, I found the Chapman "97" bit fit better than the "98," although both machines have screws with slots that seem identical to the naked eye. Test both bits first--stick them in the slot by themselves and wiggle them loosely--to see which is a better fit before you start to remove the screw.)

Please note that the Chapman bit numbers are read with the blade pointing to the left. In other words, this is a "98," not an "86:"

| Try the Chapman "98" bit as well as the "97" to see which fits better. |
