Fig. 37 Balls & ball guide halves
Fig. 38 Installing guide half & remaining balls
19.
Fill one ball guide half (43) with grease and insert remaining 7 balls (42) into this guide half. Then attach the other ball guide halves into steering
nut (4). Mount fastening clip and install hex screws with serrated washers and tighten to 8-11 ft. lbs. (12-16 Nm), Figs. 37 and 38.
Fig. 28 Measuring friction torque
20.
Position measuring fixture (70) on splines of steering worm (3) and measure friction torque of ball circuit, Fig. 28. The friction torque of
steering nut/steering worm should be 30-50 N-cm. If the friction torque is not within this tolerance, replace complete ball circuit together
with steering nut, steering worm and balls.
