Abstract
A differential lock is activated by a non-rotating piston mounted substantially inside the side quill of the differential. Non-rotating seals are provided between the side quill and the piston to form a pressure chamber for the piston. A thrust bearing is provided between the piston and the pressure plate of the clutch of the differential lock to transmit force from the piston to the clutch while allowing relative rotation therebetween.
