(B) Main PTO shaft (inner): solid shaft
As shown in the figure above, the hollow shaft A (main shaft (outer)) is fixed to the boss of the clutch disc
assembly with splines while the solid shaft B (main PTO shaft (inner)) is fixed to the PTO sleeve (2) of the
flywheel with splines.
When the engine is running, the rotating force is delivered to each shaft. When the main clutch is disengaged
in this state, the hollow shaft A does not rotate as it is fixed to the clutch disc assembly. However, as the solid
shaft B is connected to the flywheel with the PTO sleeve, it rotates continuously. As a result, the PTO shaft
connected to the solid shaft B is driven independently regardless of the driving shift condition.
The clutch is to deliver or cut off power from the engine to the transmission. When the clutch disc is pressed
against the flywheel, the rotating force from the engine is delivered into the transmission through the shaft
which is connected to the spline boss of the clutch.
However, when the clutch pedal is depressed, its clutch rod pulls the release shaft which then pushes the
release bearing in the clutch housing to press the clutch cover spring. As a result, the clutch disc is separated
from the flywheel, so rotating force from the engine is no longer transmitted to the transmission.
