If you can turn the lifter plate without the outer clutch hub turning it is effectively disengaged as I view the service manual photos. To me this goes to the diaphragm spring I mentioned in my earlier post.
Understand , I do not have a clutch assembly in my hands. I am only reading the service book and photos.
I hope the following (my understanding of the operation) helps clarify the operation of the drive system- crankshaft to output shaft.
Turning the lifter plate is turning the steel plates in the clutch pack . If the clutch assembly is engaged, the diaphragm spring is applying pressure to the pack. Turning the lifter plate to an engaged clutch turns the steel plates which are bound to the friction disc by the diaphragm spring pressure, thus connecting it to the outer clutch basket.
The outer clutch basket is driven by the crankshaft. When the clutch is engaged, it turns the inner portion of the clutch basket(steel plates) which drives the mainshaft.
When a forward gear is selected and the clutch is engaged it turns the mainshaft which turns the countershaft, which powers the output shaft.
