4 - WORN PLATE RELEASE: The toothed plate (1) is released by the diaphragm spring (3) and can therefore slip
onto the next gear tooth (7). It is now in a position to turn the gear at the next engagement.
5 – NEXT ENGAGEMENT: The toothed plate (1) presses the tooth for a distance that corresponds to the height of
the tooth. This operation turns the gear (7) and at the same time the toothed sector (5) and therefore the thrust ramp
(8) via the slanted section system. At the end of engagement, the ramp has shifted axially to the exact wear value to
be taken up.

The friction plate is fitted with a buffer damping spring system. The propeller shaft is connected to the transmission by
