Abstract
A shift system for a transfer case including a spring-loaded range fork assembly operable for shifting a range sleeve between two speed range positions. The range fork assembly includes a bracket, a range fork, and a spring assembly. The spring assembly is compressed and inserted into chambers formed in both the bracket and range fork. The range fork assembly is slidably maintained on a shift rail and the range fork is coupled to the range sleeve. An actuator mechanism is provided for causing selective axial movement of the range fork assembly on the rail. The spring assembly allows the bracket to shift and apply a shift force on the range fork. This shift force causes the range fork to slide the range sleeve to the desired range position.
