OVERRUNNING CLUTCH YOKEAB4,AW21 Series Overrunning Clutch Spring-lok Yoke
AB4,AW21 series overrunning clutch yoke with 1 3/8-6 spline bore and spring-lok connection. Note: Image color may not represent actual part.
The overruning clutch allows any implement to free-wheel to a stop. Any implement with a large rotating mass may need overload protection by allowing it to free-wheel to a stop. The clutch prevents the machine from driving the tractor when the PTO drive shaft has stopped. The overruning clutch direction is dependant on the application, the normal tractor PTO direction is clockwise . Overrunning clutches do not absorb any energy, so start up overloads must be absorbed by other means.
