ABSTRACT:
A multiple mode single lever control lever assembly includes a lever fixed for pivotal movement with a pivot member rotatably mounted in a housing. The pivot member includes detent recesses, a centering, spring-engaging tab and a friction disk-engaging finger. An arm is slidable in a bore in the housing, is biased towards the pivot member and carries a detent follower and a centering spring-engaging tab. A rotatable index member includes cam surfaces which cooperate with corresponding cam surfaces on the housing so that the index member moves axially to frictionally engage clutch disks with the friction disks upon rotation of the index member while a ramp surface on the index member engages the arm to uncouple the arm from the centering spring and to uncouple the detent follower from the pivot member.
