2. Check the gap between the bushings and the bipod shaft, which should not exceed 0.10 mm. If the clearance is greater than specified, replace the bushings using tool A.74105.
3. On the inner surface of the bipod shaft bushings there are spiral grooves that go out only on one side of the bushing. When pressing the bushings, position them so that their ends with groove outlets are inside the crankcase opening, and the groove outlets are located opposite each other. The ends of the bushings should be buried in the crankcase hole by 1.5 mm.
4. Lubricate new bushings with transmission oil before pressing.
5. After pressing into the crankcase, finish the bushings with a reamer A.90336 to a size of 28.698–28.720 mm. The mounting gap between the bipod shaft and bushings should be within 0.008–0.051 mm.
6. Check the ease of rotation of the bipod shaft roller on the ball bearing.
7. The ball bearings of the worm and roller must rotate freely, without sticking, and there must be no wear and 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 bipod shaft 7. The gap should not exceed 0.05 mm. If it is larger, replace the adjusting plate 9 with a thicker one.
Attention! Spare parts are supplied with adjustment plates in eleven sizes, with a thickness of 1.95 mm to 2.20 mm; the increase of each size is 0.025 mm.
