ABSTRACT:
A power transfer device of the type which includes a housing, a first shaft rotatably mounted within the housing to transfer drive torque from a power transmission to a set of rear-wheel drive axles, a second shaft rotatably mounted within the housing in parallel with the first shaft for drive connection to a set of front-wheel drive axles, and a pair of clutch sleeves mounted on the first and second shafts and shiftable between respective positions in which they effect drive connection or disconnection between the first and second shafts. A shift mechanism for the clutch sleeves includes a shift rod arranged in parallel with the first and second shafts and axially movably mounted within the housing, a first shift fork axially slidably mounted on the shift rod and coupled with one of the clutch sleeves, a second shift fork fixedly mounted on the shift rod at a position adjacent the first shift fork and coupled with the other clutch sleeve, and a retainer element fixed to the shift rod at a position where it is spaced in a predetermined distance from the first shift fork when the second shift fork is maintained in engagement with the first shift fork.
