(f)
Reservoirs can be pressure filled or manually filled. A hand pump and reservoir fill valve (selector) allow filling of the selected reservoir.
G. Left and Right Hydraulic System Components (Fig. 6)
(1)
The left and right hydraulic systems each have one engine driven pump (EDP) and one alternating current motor pump (ACMP). The EDP is attached to the engine gearbox on the under side of the engine. The pump is a line replaceable unit (LRU) with a rated output of 37 gpm.
(2)
The ACMPs are in the left and right mainwheel forward fairings. The associated filters, valves, and reservoir are also located in that area. The electric motor is powered by 115 vac using 45 amps at rated output. The pump is a LRU with a rated hydraulic output of 7 gpm.
H. Center Hydraulic Systems Components (Fig. 7)
(1) The two ACMP primary sources are on the left side of the airplane in the fairing aft of the main wheel well. They are mounted on shelves on the keel structure. The associated filters, valves, and reservoir are also in that area. The center ACMPs are identical to the left and right ACMPs.
