Fig. 6.21. Beam of a forward suspension bracket and steering drafts: 1 — the right rotary lever; 2 — a nut; 3 — the spherical hinge; 4 — a bolt; 5 — a collar; 6 — cross steering draft; 7 — a tip of steering draft; 8 — a sealant of the spherical hinge; 9 — a finger of the spherical hinge; 10 — the left rotary lever; 11 — the pivot axle; 12 — a rotary fist; 13 — a bipod; 14 — longitudinal steering draft; 15 — a beam of a forward suspension bracket




The pivot axle 11 and the plug (see fig. 6.21) are replaced when their total wear reached the size of 0,5 mm. The pivot axle and plugs can be replaced, without removing a forward axis from the car, in such sequence:
— to raise the car for a forward beam so that wheels did not concern a floor, to establish on supports and to remove forward wheels;
