This guide will walk you through the entire process of cleaning, repairing and adjusting the top tension unit on any
700 Series Touch & Sew machine. Common models include: 750 – 758 – 756 – 770 – 771 – 776 – 778 – 775 – 774
As with all my guides, it is assumed the user is handy with their tools, and at some point in time, has had the machine open for oiling
and cleaning. Even if you not that handy with a screwdriver, this guide should still be able to walk you through the repairing process.
Always be sure to lay the parts out in order of removal, and pay close
attention to how things are assembled before taking them apart
Basic Tool Requirements:
fig A
1.
Flat blade screwdriver, medium in size
2.
Small needle nose pliers, or better yet, round nosed pliers
3.
5/64 Allan wrench
4.
Flat blade Jeweler screwdrivers
Other Tools Handy To Have:
fig B
1.
A Moto-Tool / Dremel, would be nice, with a polishing wheel (gray
stone type). See figure b
2.
Fine sand paper, about 1200 – 1600 grit, higher if available
Note: if you need to use the sand paper, rub it on some other surface
first, so it is a little worn. All we need to do is clean any rust, or
roughness of the tension discs
3.
Crazy glue, or other type of epoxy, something that will hold very
solid over a period of time
