ABSTRACT:
A locking differential includes a plurality of spring biasing assemblies each consisting solely of a helical spring having a spring cap member mounted on one end thereof for isolating the spring from the associated locking pin that extends at one end within the oversized spring bore. The spring cap member has a disc portion the outer diameter of which is at least as great as the outer diameter of the helical spring, and a central plug portion that extends within the spring, whereby the spring bears at one end solely against the cap disc portion and is isolated thereby from the locking pin. The diameter of the cap disc portion is also less than the width of a radially extending access opening that communicates with the oversized spring bore contained in a clutch member, thereby to permit introduction of the spring with the cap mounted thereon into the spring bore via the spring access opening.
