housing, tighten torque is 45 N·m~53.9 N·m. 8.6 (Figure 10) Assemble the needle roller thrust bearing (ZDZ4-170) (3) on the head of screw, turn adjust nut (2) to housing, until the end then back 10°~25°, keep the relative position between adjust nut and housing, then tighten locknut with the torque 180N·m~210N·m. ※
Notice: Must ensure every part of bearing (3) assembles on the screw correctly, it can’t be dropped out or stagger, and should mount the thick bearing seat firstly and make it close to screw shaft. Admonition: If misplace the tooth, it will cause the travel of a certain direction of steering gear is not enough, thereby cause steering accident. Should inspect bruising of spline when assemble geared sector, prevent to cut seal. Adjusting of steering torque (Figure 10) Fix the above assembly to the clamp, turn the adjust screw (4) of pitman shaft components deasil, tweak to the end then back about 3/4 circle, ensure steering shaft run smoothly
and no
obvious lash. Keep the position of adjust screw, tighten nut GB/T889-1986-M16 (5) to 65N·m~80N·m torque. Figure 10
