- the bearing must not have any damage or wear; if the axial clearance in it exceeds 0.7 mm, it is replaced;
- the retaining ring and bearing must not be offset from the original fit; if the inner bearing ring rotates relative to the axle shaft seat, the retaining ring is replaced;
- the axle shaft must not be deformed, and the mounting surfaces must not have any scratches or damage. The axle shaft runout, measured at the centers on the journal under the oil seal, must not exceed 0.08 mm. Before installing in the center, the centering holes on the axle shaft are thoroughly cleaned of dirt and rust. Minor bending of the axle shaft rod is eliminated by straightening. After straightening the axle shaft rod, the flange end runout, measured at the centers, must not exceed 0.05 mm. If the flange end runout is greater than specified, but not more than 0.08 mm, then it is allowed to machine it to eliminate the end runout. A decrease in the flange thickness due to machining is allowed by no more than 0.2 mm.
