Is your Sachs moped having clutch issues? Not a surprise, Sachs clutches suck! No worries, here's something I did that made it work like new again.....

I'll show you how to do it.

I made it at Techshop. The have a work bay where you can work on your car, motorcycle, moped... whatever! There are 3 of them around the SF Bay Area, so it's pretty convenient. There's others around the country and they have lots of tools and workshops. Wood, Metal, Fabrics, Electronics and more. It's rad.

You'll need:

Sandpaper and a file
A flathead screwdriver
A piston stop
A socket wrench with a 17mm socket and a sparkplug socket

Step 1: What's Wrong????

The Sachs clutch is pretty simply, yet it can have various problems. With your clutch apart, look for obvious problems, like broken springs or friction discs. If those are broken, you'll need to replace them.  Sachs clutches have a tendency to "glaze over", so start by sanding the surface of the friction discs, just a little to remove any shine. Those friction discs are sandwiched between your clutch plates. With rough sandpaper, scratch crosshatches into the surface of those clutch plates. We want the clutch to grip as well as possible.

When the clutch is together, it moves up and down the notches in the clutch bell, and after time it creates burrs in there. When those burrs get big enough, they hang up the clutch and it don't work no more.   :(

Use a file on those notches of the clutch bell, if you have big burrs, just to get it smooth again. Then finish it off with some 220 grit sandpaper. Do the same on the clutch plates if it's rough there. You might need to lightly sand those spots in the friction discs as well.

When you think it's good, put the clutch pieces together and squeeze it to see if it moves smoothly. It should.
