Spares: Late Clutch (Finally) Disassembled

Can't believe it took this long to finally get the clutch from the Late Bottom End apart.  I got stymied a few times trying to get the damper springs out first, which was completely the wrong thing to do.  It's a little mechanical hubris in not going back to Clymer's to refresh my memory on the procedure.

The first thing I needed to do was compress the clutch, then remove the clip, then remove the springs.

Go figure.

But the even bigger revelation came when I realized that Viola's clutch was NOT an S90 clutch after all.  I had always thought this Late spare clutch was the oddity, not having the screws I was familiar with.  All the while, it turns out Viola's clutch was actually a centrifugal type.  How did I keep missing that fact in the book?

Turns out the true S90 manual clutch is ten times simpler than the centrifugal version, as you'd expect.  You compress it, remove the clip, pop out 2 friction plates and 2 steel plates and you're done.  I also used 2 sockets (chrome 21mm, black 29mm) on the ends of the compressor tool (instead of a wrench placed crosswise like I used to) which made things even easier.

Finally, when measuring the friction plates, I found they were 2.92mm and since the standard is 2.8-2.9, it means they must be brand new.  The springs were also good at 26.6 (with 26mm wear limit).
