5. Tighten until cover and housing are fully engaged
metal-to-metal (see Figure 2-8). Once metal-to-metal
contact has been made, it is not necessary to tighten
the cover any further.
6. Visually inspect both covers to ensure they are
installed metal-to-metal. Visual inspection is sufficient
to ensure metal-to-metal contact; however, a gap
gauge may be used for verification if desired. When
metal-to-metal contact has been made, the
acceptable gap between cover and housing will be
less than 0.010 inch (see Figures 2-9 and 2-10).
NOTE
Replace the cover O-rings per the steps outlined in
Electronics Housing Reassembly section if either cover was
installed metal-to-metal and then removed.
