Once the parts have been properly cleaned, youshould inspect them for damage or wear and replace orrepair the parts as necessary. Before reassembling theejector mechanism, apply a light coat of general-purpose preservative lubricating oil (VV-L-800). Toprevent the piston from locking up, you must wipe offall the excess oil.For further information concerning the Aero 7A-5and Aero 7B-4, refer to the publication Ejector RackAssembly Model Aero 7A-5, NAVAIR 11-5D-20.BRU-10A/B AND BRU-11A/A BOMBEJECTOR RACKSThe BRU-10A/B and BRU-11A/A bomb ejectorracks are used to mount and sway brace a singleweapon/store or for a variety of multiple weapon/storeadapters. The BRU-10A/B bomb ejector rack is pylonmounted on the wing stations of the A-7E aircraft. It ispart of the aircraft’s basic weapon/store suspensionsystem. It may also be weapons-rail mounted to theF-14 aircraft fuselage. The BRU-11A/A bomb ejectorrack is pylon mounted on the wing stations of the S-3aircraft. It is part of the aircraft’s basic weapon/storesuspension system.BRU-10A/B Bomb Ejector RackThe BRU-10A/B bomb ejector rack (fig. 10-15) hasfour suspension hooks-two hooks spaced 14 inchesapart and two hooks spaced 30 inches apart. It carriesweapons/stores weighing up to 4,000 pounds. Thebomb ejector rack has the necessary electricalconnections, mechanical and electrical arming units,ejection components, and the mechanical linkage forsafely suspending and ejecting weapons or stores.Although the BRU-10A/B bomb ejector rack differsfrom the bomb ejector racks previously discussed, thebasic principles of operation are the same, except for theoperations discussed in the following paragraphs. Asyou read them, refer to figure 10-15.A manual cocking bolt and a manual release bolt arelocated on the forward left-hand side of the frameassembly, Before you load a weapon or store, manuallycock the mechanical linkage by rotating the cockingbolt. This places the linkage sears in a position to lockthe suspension hooks when they are moved to the closedposition. The suspension hooks may be released(opened) by manually rotating the manual release bolt.To prevent damage to the mechanical linkage, you mustremove the safety flag assembly (safety pin) before yourotate either the cocking bolt or the release bolt.Figure 10-16.—BRU-10A/B bomb ejector rack hook latchedindicators.To find out if the suspension hooks are properlyIocked, you must visually check the latch inspectionholes (fig. 10-16) located in the frame assembly aboveeach hook. If the hook is properly locked, you can seea silver latch indicator through the latching inspectionhole. If the hook is not locked, you can see a blue orsilver latch indicator. If the hooks are unlocked (open),the latching inspection hole will be blank.The BRU-10A/B bomb ejector rack is designed tohold one ejector assembly that can be inserted in thebomb rack in one of four different positions (fig. 10-17).Figure 10-17.—BRU-10A/B bomb ejector rack ejectorassembly and installation positions.10-13
