Motor runs machine jams, wheel hard to turn

If this is an older metal mechanical machine, it may be seized due to lack of oil.


Wheel on right side that controls the needle up and down is very tight...

indicates needle thread tension not tight enough
the jamming may be from thread and fluff wound tight around the bobbin shaft an locking it up
remove any threads and other material from the bobbin shaft and bushes
take it in for a service

Check to see if the bobbin case is in correctly. Jamming occurs when something isn't in machine properly. Try taking out the needle & manually turning the hand wheel slowly. It could be just a bent needle too.

Usually, the needle & fabric will release if you are able to remove the bobbincase and the needleplate. You should probably try to do this to remove the broken needle tip, although usually it will drop out of the bobbin area and land somewhere in the bottom of the machine.

Sounds like the motor might be having problems. I would take it in for a proper servicing.

No......CHANGE the needle,,,,it will damage your fabric!!
GET IT SERVICED....It needs retiming by the sound of things

Try the process of elimination. Take out the needle, take off the needle plate, take out the bobbin case. Run the machine. Does if run full speed? You might have to let the machine run for about 5 minutes. If it runs slow or you hear it slow down, you might have a bad connecting link between the needle bar and the main shaft counter weight. They seize up sometimes. (Shop Repair).

Thread is caught in the hook...Remove the upper thread and bobbin case, turn the hand wheel backwards and forwards by hand and remove the thread remands

this very same thing happened to my flat machine turned out to be a piec of material jammed in the workings also wrong oil used or it might be thread jammed try and see

It's been a while since this machines been oiled. try oiling both motor hole and needle operation.
