CLUTCH ASSEMBLY/DISASSEMBLY
The use of the special tool is fundamental to disassemble the SAC
clutches. If you try to disassemble a SAC clutch without its tool, the
clutch will lose its adjustment and cause operating problems, and you
may damage the mechanism or injure yourself.
1. Unscrew and remove 3 screws from the clutch mechanism at 120°.
Select the screws (spacers) of the special tool suitable for the clutch
to be disassembled and position them in place of the 3 previously
disassembled screws.
Then check the tightness with a wrench ( g. 1).
Note: On some clutches, you will need to remove 4 90° screws and
use the 4 point star for the following steps. Nevertheless, the process
remains the same.
2. Position the socket stop screw in the centre of the 3- or 4-pointed
star and screw in as far as it will go. Then position everything on the
spacers and lock the star on the spacers using the nuts provided in the
box.
3. Turn the push screw by hand until it touches the diaphragm blades
and then continue turning with a suitable wrench.
The diaphragm begins to compress (Figs. 2 and 3).
4. Once the diaphragm is fully compressed, loosen the last remaining
screws of the clutch mechanism ( g. 4).
The clutch is now fully unscrewed.
5. Carefully loosen the tool stop screw completely. Resistance can be
felt and the clutch system must gradually move away from the ywheel:
this is normal.
6. Remove the tool (nuts securing the star, star + stop screw and
spacers). You can now safely remove the clutch and its mechanism.
