- whether there are any signs of wear, jamming, dents or scratches on the working surfaces of the roller and worm. Worn and damaged parts are replaced;
- the gap between the bushings and the pitman shaft. If it is greater than that specified in table 18, then the bushings are replaced;
- ease of rotation of the pitman shaft roller and worm bearings. The latter should rotate freely, without jamming, and there should be no visible wear or damage on the surface of the rings and balls;
- runout of the bearing journal of the steering shaft relative to the average diameter of the spline hole of the shaft end. To do this, a special mandrel is put on the lower end of the shaft, which is installed on a prism. When turning the mandrel on the prism, the runout of the bearing journal should not exceed 3 mm. If the shaft is deformed, it is straightened on a hand press;
- axial clearance between the head of the adjusting screw 2 (see fig. 125) and the groove of the shaft 11 of the pitman arm. The gap should not exceed 0.05 mm. If it is larger, replace the adjusting plate 1 with a plate of greater thickness.
