ABSTRACT:
A transfer case fork assembly for selectively shifting a vehicle powertrain clutch between two speed ranges. During the shifting to either speed range a momentary lock-up condition may result because of the applied torque to the transfer case output shaft. The invention uniquely arranges outer and inner nested spring biased brackets on the shift rail allowing subsequent lagging travel of the fork and clutch. The arrangement provides lost-motion travel of the manual shifting controls during the momentary clutch lock-up condition. Upon freeing of the clutch the spring biased brackets advance the fork thereby engaging the clutch in either its high or low speed range mode of operation.
