You may need to engage the safety clutch manually, with a screwdriver. Here is a video that shows how the safety clutch mechanism works, and how to disengage/engage using a screwdriver.

 

Well Ill be damned, less than 24 hours and you have helped me troubleshooting an issue ive had for over a year. The drive shaft is now turning. Ill keep you updated on any issues that may follow... do I use it manually to ensure that all blockages are removed for the time being?

Make sure the handwheel turns freely (easiest to check with motor drive belt disconnected), and that it forms stitches. If all checks out you can reconnect the drive belt and go back to stitching under power.

The safety clutch may disengage again if too much load is placed on the hook driving shaft. Two things that will make it go much better for you:

1. Start each seam with the take up lever at its highest position
2. Hold the top thread for the first couple of stitches

I was trying to figure out what might have caused the issue initially and it became clear very quickly when rethreading! So the little black guide photographed doesnt click as I am led to believe it should? So the thread gets wrapped around the disc after a couple of revolutions and the thread tension is far too high. Ive asked a lot from you already but do you have any further advice regarding this matter? 

Thank you all again, Merrick 

Sorry, photo attached here

That little black guide is called a check spring. It's a very important part of the thread path.  The "snap' you mention is the sound of the thread snapping behind that teeny little tab, visible through the oval hole next to the screw.  If it's not snapping in, try holding the thread that's above the check spring so that it doesn't pull from the spool.

At that point in your threading process, you could drop the presser foot. That will clamp the tension discs down and should hold your thread.

Based on the angle of the thread coming off the check spring, it looks like it's behind the tab. I think.

Around the disc? Meaning more than what is shown in the photo? (The photo looks correct to me)
