Maintaining and Servicing the Valor
Removing and Reinstalling the Light Bar Lens
The light bar lens, which is the top half of the Valor housing, covers the ROC (Reliable
Onboard Circuitry) PCBs and controller PCB.
Tool required:
T27 Torx driver
Removing the Lens
To remove the lens:
1.
Disconnect all power to the light bar either at the battery or at the light bar. See
“Disconnecting/Connecting Power and CAT5 at the Light Bar” on page 38.
2.
Use a T27 Torx driver to remove the 1/4-20 Torx-head barrel nuts securing the lens
(Figure 13). Carefully remove the lens and gasket as a unit. Avoid damaging the lip
seal.
3.
Verify that an O-ring is under the head of each barrel nut and not stuck to the
lens. Use a wooden or plastic pick to carefully remove the O-rings from the lens to
prevent damaging them.
4.
Inspect the O-rings and the lip seal for deformation, brittleness, cuts, or tears. To
maintain watertightness, replace a questionable O-ring or seal.
5.
Inspect the lens for cracks, crazing (hairline cracks) and other defects.
