Pulley and gear arrangement, the motor is on the right.
When I took this photo I had already taken the little plastic cap which is screwed in by two screws off. Now that I could see a bit better what was going on I took the entire machine off its base. This is probably not essential but makes visibility a lot easier. I was now left with this:
The black belt connects the gears and pulley to the main drive of the machine. When you have unscrewed the machine from the base tip it downwards slightly to facilitate getting that belt off. I have also taken the toothed belt that runs from the motor to the pulley off. Now take the white cover off and follow with the grub screws holding the pulley on.
Now by rotating the pulley until one of the holes is positioned directly over each of the screws on the right hand side in turn and removing them you can get the whole gear set up out. You should now have this:
This can now be pulled apart even further:
I pulled mine apart and lubricated everything that could possibly move. I then re-assembled it and put it back on the machine. I'm not exactly sure what was wrong with it but it doesn't grate any more unless you apply a force when it is turning. I suspect there is a small clearance somewhere but although I tried for quite a while to find it I was unsuccessful. It's almost ready for sale now, at a reduced price because of the cracked cams.
I will hopefully be uploading a manual for one of these shortly. Has anyone out there sewed with one of these in better condition? What are they like?
