Positioning the expansion racks

Procedure

  1. Determine the position of each expansion rack to be installed to this Rack-1.
    1. When viewed from the front of Rack-1, each expansion rack is installed to the right. See Figure 1.
    2. Use each expansion rack number label Callout label 2 (Figure 1) to ensure it is for this Rack-1. The Rack-2 label must list the Rack-1 serial number.
      Attention: This storage facility installation will fail if an expansion rack is for a different Rack-1. If the Rack-1 serial numbers do not match, stop the installation and call the next level of support.
    3. Roll the expansion racks being installed into position. Keep them about 20 cm (8 inches) apart from each other.

  2. On the rear of each expansion rack being installed, remove the right cover.
    1. On the upper and lower door hinges, loosen the screw  1  and move the retention plate  2  that prevents the hinge pin  3  from being removed. Refer to Figure 3.
    2. Remove the hinge pins, remove the rear cover and place it in a safe location.

    1. Roll Rack-2 into position approximately 3" (75mm) from Rack-1.
    2. In the expansion rack ship group, locate:
      • 4 x spacer studs P/N 22R5046
      • 7 x spacer mounting bolts P/N 1621545
      • 4 x M8 washers P/N 84X5850
    3. See Figure 4. The front of the rack uses two spacer studs, four bolts and four washers.
    4. See Figure 4. The rear of the rack uses two spacer studs, three bolts and no washers.
    5. In the rear upper left corner of Rack-1, next to the hinge, there are two holes; one above the other. See Figure 5. In the lower hole, install a spacer stud with a mounting bolt. Leave the bolt loose so the spacer studs can move to line up with Rack-2.
    6. Install the remaining three spacer studs to Rack-1. Leave the bolts loose so the spacer studs can move to line up with Rack-2.
    7. Move Rack-2 into its final position and install the bolts and washers as shown in Figure 4.
      1. To access the front lower left bolt, you must temporarily remove the battery service module enclosure cover (if present)
        Note: These covers are not used on later versions of models 961 and 96E.
      2. At the bottom of the cover, pull the knob out on both fasteners.
      3. Pull the bottom of the cover away from the BSM set.
      4. Lift the cover up until the two top sheetmetal tabs release from the BSM set enclosure.
    8. When the alignment is correct, tighten all the bolts that have been installed.
    9. Install the BSM set enclosure cover (if removed).
    10. Install the wheel chocks Callout label 1 (located in the ship group) on all four casters. See Figure 6.
