Fix:

1) the higher of the ladder position rubbed off with a ruler placed on watch no light shall prevail
2) the bearing bell big endian removal of 8-10mm.
3) Due to the eccentric shaft threads have been damaged, you can not tighten the nut, now thick 16mm steel plate lathe a ring, the ring diameter and bearing small end diameters are the same, the same outside diameter cylindrical nut with bearing.
4) ring, nuts, bearings and packaged with a place, ring and shaft 6:00 uniform symmetry welding, each weld 20mm. Welding, intermittent, and can not let the axis of the heat is too large Jaw crusher tooth plate.
5) After welding the nut to tighten ring, so that the bearing sleeve to move backwards and shaft fastening, which is especially important.
6) Finally, ring and bearing nut, welding 2:00 welding, nut, weld length 10mm can.
