MWO 9-2300-378-34-2 b. Installation of Solenoid Valve Assembly. NOTE The damper end (accessory end) or the engine will be called the front and the transmission end the rear. As viewed from the front of the engine toward the rear, the side to the right will be called the right bank and the side to the left will be called the left bank. NOTE During the following modification, clean all pipe threads (both male and female) with dry cleaning solvent PD-680 and apply teflon tape (antiseize tape MIL-T-27730). Lube threads of all tube fittings with technical petrolatum VV-P-2 36. (1) Remove protective plugs and felt filtering discs (if present) from inlet and outlet ports of the solenoid valves. NOTE It may be necessary to reposition receptacle connector to install nipple AN911-2. If connector must be repositioned, secure valve in a soft-jawed vise (or wrap a rag around valve and secure in vise) and loosen acorn nut on top of valve and reposition connector. (2) Apply teflon tape to threads of pipe nipple AN911-2 and install nipple between outlet port of one solenoid valve and inlet port of the other (figure 5, view A). The bottom surfaces of the valves must be parallel. (3) Place solenoid valve in soft-jawed vise or in vise with rag. Apply teflon tape to threads of 90 elbow, MS518 15-36 and install in solenoid valve inlet port. Tighten to five o’clock position (figure 5, view B). (4) Place the second solenoid valve in soft-jawed vise or in vise with rag. Apply teflon tape to threads of 90 elbow MS51815-36 and install in solenoid valve outlet port. Tighten to twelve o’clock position (figure 5, view C). (5) Check position of receptacle connector on each solenoid valve 11668627-2. Connector should be positioned 45° from inlet port as shown in figure 5, view D. If connector must be repositioned, secure valve in a soft-jawed vise (or wrap a rag around valve and secure in vise) and loosen acorn nut on top of valve. Reposition connector and torque nut to 50 lb.-in. (5.6 n.m). 15
