TYPE B: SEPARATED SHIFT CLUTCH
The centrifugal clutch and the shift clutch are separate in this type, increasing the clutch capacity in comparison with the
combined type described on previous pages. Differing from the type mentioned in the previous section, the centrifugal clutch
has a mechanism whereby the clutch shoe attached to the crankshaft is expanded outwards by centrifugal force, and the
shoe is pressed against the inner surface of the clutch drum, allowing power transmission. This is a similar mechanism to a
drum brake. The shift clutch is attached to the mainshaft as with a manual clutch. The work of engagingldisengaging is also
the same as with the manual clutch. The gear shift lifter mechanism is the same as that of the combined type described in the
previous section.
