Reverse Check Mechanism: Construction
The construction of the reverse check mechanism is as shown in the drawing on the opposing page.
The reverse check sleeve is bolted to the transfer case and houses the mechanism main components.
The reverse accent shaft is slidable inside the reverse check sleeve and its smaller-diameter end is fitted with the reverse check cam. The cam can rotate and move axially on the shaft but its leftward movement is restricted by a step formed on the sleeve inner wall.
The reverse accent shaft has hollows in both ends. In the left end hollow are the 1st return spring and its cap and in the right end hollow is the reverse return spring, which pushes the shaft leftward.
Around the check cam is the reverse check spring whose left end applies simultaneous leftward and rotational forces to the cam.
Both the reverse check spring and reverse return spring are retained at their right ends by the reverse check plate which is held in place by the snap ring.
The reverse accent shaft has a V-groove in which the detent ball is pressed by the reverse accent spring fitted through the hole in the reverse check sleeve.
The reverse check sleeve and reverse accent shaft have a slot and a notch at their bottoms, respectively, and the selector arm is inserted in the notch through the slot.
