ABSTRACT:
The wall portion of a chain-type 4-wheel drive vehicle transfer case disposed adjacent and generally paralleling the slack reach of the transfer case chain when the associated vehicle is being driven in a forward direction has an opening formed therein registered with the midportion of the slack reach and a mounting plate having an opening formed therein is secured in position over the external surfaces of the wall portion with the openings registered with each other. One end of a guide sleeve is secured to the outer surface of the mounting plate in registry with the opening formed therein and an elongated shank member is slidably supported from the sleeve and projects through the registered openings with one end of the shank member projecting into the sleeve and the other end of the shank member projecting into the transfer case. The sleeve is provided with structure engaged with the shank member adjustably limiting movement of the shank member outwardly through the openings and the other end of the shank member disposed within the case journals a roller therefrom for rotation about an axis transverse to the shank member. The roller inwardly deflects and is rollingly engaged with the slack reach of the chain in order to limit the slack thereof.
