5-1 Storage Of Items
(1) Long-term storage of items is limited to 12 months. As a rule, items stored in excess of this must be overhauled. All seals must be replaced and all parts must be checked for rust or other defects.(2) When storage is to be arranged without the main pump and 3rd pump installed, use care so as entry of foreign matter from pump mount is prevented.(3) Store items in conditions that prevent damage to mating surfaces.(4) Put items into service only after checking for oil leakage from seals and other likely trouble during operation if storage has been for a period of 6 to 12 months.(5) Rust-preventive treatment must be given to all items before storing.(6) Store items without any external load applied. Also use care so as protruding items like air breather, level gauge rod, etc. will not be damaged.(7) Select an appropriate place to store items, such as a dry, clean place that is not exposed to the weather or direct sunlight. Note that items will require overhauling much earlier if stored in unsatisfactory circumstances.1. Cleaning 1) Remove dust, dirt and moisture with a clean cloth. Take necessary steps to remove rust if items gather rust.2) Use cleaning agent (PS-661) or trichloethylene to completely remove grease.3) Use methyl alcohol or fingerprint remover [MIL-C-5074 (P-O) or equivalent] to remove finger marks and make surface completely clean.4) Clean by brushing or wiping with a cloth.5) Do not attempt to clean coated parts, parts using rubber or other materials or parts affected by solvents.2. Internal rust preventionIf items are to be stored for a long period, fill the inside with gear oil (SAE No.30 or equivalent) to prevent internal rust, and select a dry clean place.3. External rust preventionProtect noncoated parts from rust as follows:1) Apply a coat of rust preventive grease [MIL-G-3278 (P-11) or equivalent] by brushing on mating surfaces and port flanges. Give an even coat of rust-preventive oil [MIL-L-644 (P-9) or equivalent] to other parts.2) Cover finished items with vinyl sheeting or barrier paper (MIL-B121 or equivalent) after coating with rust preventive compound. Store items in a well-ventilated place. Tape up covers if necessary.3) Remove the cover and wipe off rust preventive grease with a cloth. Use a cleaning agent unlikely to affect rubber or similar materials for removal if necessary.5-2 Storage Of Parts
