Just like the Syncro starter, Sach is saying one size fits all.
Unfortunatly, this is not true. But, for the limited number of Syncros
out there, and the likelyhood of someone spinning the clutch disc
to fast, like I did, Sach is obviously not going to be bothered with
an additional part number, just like Boucsh(sp).
The problem lies in the hub. Centrifical force will blow the stock
disc apart. This can happen only if you have your Syncro in low
gear, drifting down a hill with the clutch disengauged. The wheels now
are turned the disc. The engine, being the clutch is disengauged, will
not limit its speed. With the very low gear ratio running backward,
the RPM's can really get up there.
IMHO, just don't hold your clutch in, with your Syncro in low,
and drift down any big hills.
On the other side of the coin, Sach could have a stronger hub
for all there clutch discs that they sell for Vanagons.
