Question about Necchi 4575 Mechanical Sewing Machine
Sewing a pillow case and suddenly the needle won't move --- at all. With pliers broke needle, removed fabric. The large wheel which runs the needle etc. won't budge. The bobbin feature works. To engage this feature, have to unlock wheel. All that is fine. Just the needle won't move. Any ideas? Thanks. Lisa
Untangle any mess under and around the needleplate very gingerly trimming threads as you go if necessary....remove and clear.
Undo the needle clamp and remove the remains of the needle.
Open the door for the bobbin and bobbin case and undo the clips holding the hook in place......don't force anything, just ease any tangle loose slowly.
You may want to take a photo of how it goes back together if unfamiliar, or lay the bits out sensibly, so you can replace easily later.
Inside the bobbin/hook area is the most likely region for thread jamming the motion of everything, so make sure all is clear and clean, then.......
Without replacing the bobbin or hook, test the handwheel after cleaning before re-assembly.
You may also want to check the take-up crank for thread jams........the small arm in the top cover that moves up/down to "take-up" the top thread has a cam attached to the top shaft and often tangles thread around the shaft, open the L side cover to access.......remove thread by unwinding handwheel manually ....again be patient and careful not to break threads.
