Place wooden blocks (12”x12” stock) under each end of each bottom beam and remove dolly half from maneuvering position (Refer to Appendix B, Section b). The condition of each dolly half should resemble Figure 4. NOTE Removal of the top hooks, detent lanyard pins, and toolbox-mounting brackets (front dolly) is not necessary. 5. Remove the top and bottom beams and positioning cylinders from both the front and rear dollies (Figure 5) (Refer to Appendix C, Section a). NOTE The preferred method of applying the MWO is performing the required cutting, grinding, welding and painting WITHOUT removing bottom dolly beams from dolly suspension (see Figure 5). The bottom beams of the dolly may be removed from the dolly suspension if required IAW TM 9- 2330-390-14&P. However extreme care must be taken during reassemble due to close tolerances. 6. With a permanent-marking device, appropriately identify each support beam for future reference (i.e. front bottom, front top, rear bottom, or rear top). 7. Clean and inspect all parts (Refer to Appendix C, Section b). b. TOP AND BOTTOM BEAM PREPARATION NOTE Preparation procedures are NOT the same for the front and rear or the top and bottom beams. Discrepancies will be noted when necessary. All surfaces to be welded should be free of paint and other surface treatments. Three recommended methods for removal are the use of plastic media blasting at approximately 40 PSI, the use of paint remover such as MIL-R-81294, type I, or the use of a hand-held portable sander/grinder equipped with a wire brush. 1. Remove the vertical tubes from the top and bottom beams obtained from both the front and rear dolly. Cut tubes within 0.5 in. from each support beam surface (Figure 6). 2. Grind off remaining tube material flush with surface of beam at all vertical tube connections.
