	Place the spur gear section of the shaft in a vise equipped with copper jaws. Install the bearing retaining nut and tighten it securely using the special J-1316 wrench. With the nut in a locking position, install the nut lock. The shifter sleeve, having three tapered teeth in each side which work in connection with the detent lock balls and springs in the shaft, must line up with the position of these balls and springs. The tapered teeth in the shifter sleeve are unevenly spaced, and to find the correct position for installation count the number of teeth between the
