opalstar, there's a coil spring inside the arm of the machine that pushes the motor against the handwheel, yours is probably just out of place. Here's how you can check, its fairly simple:
First, you have to go underneath and push some wire up into the arm so you have some slack to pull the motor off: [ATTACH=CONFIG]596486[/ATTACH]
Second, loosen the stop motion screw so you can remove the knob and the handwheel:

Now you can rotate the motor about a quarter turn clockwise, where it can be pulled off. Take care you don't drop the motor, as it could yank the wires out.

This what it looks like pulled off, the spring that I'm holding with my pinky is the one that's either missing or out of place on yours. Note where it goes on the motor, there's a rod inside the arm that it slides over. Hope this helps, lmk if you need me to clarify something.
