2. Check the clearance between the bushings and the pitman arm shaft, which should not exceed 0.10 mm. If the clearance is greater than specified, replace the bushings using the A.74105 mandrel.
3. On the inner surface of the pitman shaft bushings there are spiral grooves that come out only on one side of the bushing. When pressing in the bushings, position them so that their ends, having the groove outlets, are inside the crankcase opening, and the groove outlets are located opposite each other. The ends of the bushings should be recessed into the crankcase opening by 1.5 mm.
4. Before pressing in, lubricate new bushings with transmission oil.
5. After pressing into the crankcase, finally process the bushings with the A.90336 reamer to a size of 28.698–28.720 mm. The mounting clearance between the pitman shaft and the bushings should be within 0.008–0.051 mm.
6. Check the ease of rotation of the pitman shaft roller on the ball bearing.
7. The worm and roller ball bearings must rotate freely without binding and there must be no wear or damage on the surface of the rings and balls.
8. Check the axial clearance between the head of the adjusting screw 8 (see Fig. Steering gear housing parts) and the groove of the pitman arm shaft 7. The gap should not exceed 0.05 mm. If it is larger, replace the adjusting plate 9 with a plate of greater thickness.
Attention! Eleven sizes of adjusting plates with thickness from 1.95 mm to 2.20 mm are supplied as spare parts; the increase in each size is 0.025 mm.
