35.000.69 , Rev. 4 Page 4 5.0 Precautions and Limitations 5.1 Ensure the external surface of the component and its surrounding 4 area are free of dust, soil, foreign materials, rags, loose objects, and debris prior to commencement of work. 5.2 All lif ting, supporting, and positioning of heavy components is to be performed in accordance with Reference 3.1.5 (MI-M338,
" Guidelines and Practices for the Use of Hoisting and Rigging Equipment").
5.3 Unless otherwise directed, during disassembly discard all used 0-rings and gaskets. 5.4 Use suitable temporary covers on open piping, pump cases, flanged mating surfaces, valves, etc., to preclude the entry of foreign E material into the system and to protect sealing surfaces from damage. 5.5 Provide adequate thread protectors to prevent damage to shaft threads and body bound stud threads. 5.6 Establish a designated storage area for parts removed during disassembly. Tag parts removed to ensure proper reinstallation. Document location of storage area in the Remarks section of Attachment 1. 5.7 Match mark parts as required during diassembly to aid in proper orientation during reassembly. 5.8 Observe applicable radiological precautions. Contact Health Physics for guidance, as required. 5.9 All bolting and torquing shall be in accordance with Reference 3.1.3 (MI-M055, " Bolting and Torquing Guidelines") . 5.10 During the disassembly / assembly of the pump, do not allow the pump shaft (10) to strike any hard objects. 5.11 The mechanical seal (429) is very delicate and extreme care must k be exercised during the removal, handling, and installation of the sealing components. Direct bare hand contact with the sealing faces will cause etching and poor seal performance. 5.12 Do not bend or kink the oil rings (31) when removing / installing the shaft assembly. 5.13 The inner and outer thrust bearings (204) must be seated against the shaft shoulder, with the wide flange of the outer race facing toward the pump coupling.
