Power Steering (Constant Control): Overhaul: Notes
WORM SHAFT AND PISTON REPLACEMENT NOTE : Master serration on power steering gear worm shaft spline, used for centering steering shaft coupling, is machined after steering gear is completely assembled. Should it become necessary to replace a power steering gear worm shaft and piston assembly, it will be necessary to file a master serration on the spline of the worm shaft. To file a master serration, power steering gear must be assembled and worm shaft centered in its travel. With steering gear in its normal upright position remove one tooth of the spline, at the 12 o'clock position, with a suitable file.
