tative sample indicates that such mounts will perform in accordance with test requirements of Specification MIL-M-45907. (5) Replace unserviceable skids. Fabricate skids from wood conforming to Class A of MIL- W-3912. Wood shall be pressure creosoted in accordance with requirements of TT-W-57. (6) If interior or exterior of container required removal of paint or rust by power buffing, apply spot prime and paint, as required. If container required abrasive blasting, remove grit and coat with one coat of primer 8010-161- 5718 (TT-P-636) or 8010-298-3867 (TT-E- 529) or 8010-292-3741 (TT-E-485) Type IV) as prescribed by TM 9-213. e. Assembly and Pressure Check. (1) Assembly. Coat a new or serviceable sealing gasket or “O” ring with a thin, uniform film of sealing compound conforming to MIL-1- 8660 and install on lower section mounting flange. Install air pressure gage in place of relief valve (fig. 8-7). Assemble upper and lower sections of container and torque tighten bolts to 90-105 lbs. ft. (2) Pressure test. Pressurize the container to 10 psi using air that has passed through water separator - 4920-242-400 or equivalent. Im- merse container in water. Evidence of air bubbles due to air leaks will be cause for rejection and rework. The alternate method of checking is to pressurize container to the specified 10 psi and allow container to stand for a-minimum of 12 hours. Any appreciable drop in pressure will be sufficient cause for rejection. If the container air pressure is maintained satisfactorily, release pressure, remove air pressure gage and install relief valve. f. Container Markings. The container shall be marked in accordance with MIL-STD-129 and as follows: (1) Adjacent to lifting rings, eyes, or lugs, (with arrows 5 inches long pointing thereto), mark in 10 inch letters, LIFT HERE. (2) Adjacent to and above air-filling valve, mark in 1-inch letters, AIR VALVE, and below, FILL TO 5 POUNDS PRESSURE. (3) Adjacent to and below air-filling valve, mark in 1-inch letters, USE DRY AIR ONLY. (4) Adjacent to and above the item-record receptacle, mark in ½-inch letters, RECORDS. (5) Adjacent to and above the humidity indicator, mark in ½-inch letters, HUMIDITY INDICATOR. (6) Adjacent to and, above the relief valve, mark in ½-inch letters, RELIEF VALVE, and below, DO NOT DISTURB. (7) Along warning closure flange on both sides of the container, mark in 1-inch letters, WARNING: RELEASE PRESSURE BEFORE OPENING CONTAINER. (8) At loaded center of balance (43-inches from relief valve end) on both sides of the lower section of the container, mark a vertical line 6- inches high and 1-inch wide with adjacent 1-inch letters, CENTER OF BALANCE. (9) Each container shall be provided with a name plate conforming to Specification MIL-P- 13525 and shall be secured to the record receptacle end of container. (10) Each container shall contain a decal (10912360) with instruction for assembling container. Decal will be secured to the inner wall (fig. 8-9) of the lower section at the name plate end of the container. g. Preparation of empty container for Ship- ment or Storage. After the container has been reconditioned, pressure checked, and has had the proper markings added, remove the upper section of the container. Install and secure the mounting brackets and hardware used to secure the engine in the container. Apply a film of sealing compound conforming to MIL-I-8660 on the container gasket and assemble container. Torque tighten the bolts to 90-105 lbs ft. Add 5 to 7 psi of dry air and allow sufficient time to insure that the air pressure is retained. 8-11. Engine Preservation a. Preservation Through the Fuel System. Equip an auxiliary fuel container, with a fuel line, and - fill with a sufficient amount of preservative oil, conforming to Specification VV- L-800, to operate the engine as prescribed below. Arrange the container to provide adequate pressure to assure proper supply of the preservative oil to the fuel system. Disconnect the fuel line at the most convenient point nearest to the engine fuel pump and connect the line from the auxiliary fuel container to the fuel-to- engine line at the point of disconnect. Disconnect the engine fuel return line at the quick disconnect coupling and connect a transparent plastic line to the disconnected engine fuel return line with the other end inserted into a recovery container to collect the returned diesel fuel. The fuel valve on the auxiliary fuel container shall be 8-16
