Bart Sanders on how to install
clutch disks... the proper way.
"With two standard BMW clutch assembly
tools putting pressure on the springs, lining up all the
plates is easy"
"The other tool is a BMW R60 tool
modified for holding two halfmoon keys which keep the
clutch splines in line. A a center notch gets the clutch
plates in a centered position."
"Attaching the gearbox [to the engine]
is a piece of cake now. It slides in easily."
