(3) The gap between the taper sleeve and the upper part of the main shaft, which is more than double the original assembly clearance (see Table 3) or severe cracks should be replaced;

(4) If the tooth thickness of the conical large gear is more than 20%, it shall be replaced;

(5) The lower end thrust bearing pad of the eccentric bushing shall be replaced if the wear non-parallel deviation exceeds 0.1 mm or the thickness wears more than 5 mm.
