MIL-PRF-63004D(TM)
b. Lubrication point notes. Lubrication point notes shall provide instructions for
applying lubricants, taking into account the following factors:
(1) Type, grade, availability, and properties of prescribed lubricant.
(2) Expected temperature.
(3) Lubrication gun and tools available to authorized maintenance level.
(4) Types of lubrication fittings.
(5) Possible ill effects of excessive or insufficient lubrication.
Caution shall be stressed where over or under lubrication of a part will damage that part or
closely associated parts. Such cautionary notes shall be included either as a portion of the point
note, or as a special note (see para 3.8).
3.5.6 Disassembling/and hand packing. If applicable, disassembling and hand packing
instructions shall be provided for medium and high speed antifriction bearings which are
sensitive to the amount of lubrication applied and do not have bleed holes or relief valves.
3.5.7 Cleaning, disassembling, and reassembling. Cleaning, disassembling, and reassembling
instructions required before or after lubrication shall be provided. If instructions are extensive
and contained in a technical manual, the TM shall be referenced.
3.5.8 Washing and natural drying. If applicable, instructions shall be given for washing and
natural drying of finely machined and dirt-sensitive parts before relubricating. Use of
compressed air jets or temperatures above 212 degrees Fahrenheit shall not be prescribed.
3.5.9 Preservative material. Instructions shall not specify a coating of preservative material,
either before or after packing parts that are lubricated with grease; nor shall they specify an
application of oil, solvent, or additional grease to a "sealed-for-life" or prepacked antifriction
bearing.
3.6 Lubricants and military symbols. Unless otherwise specified by the contracting activity,
lubricants shall be identified by standard military symbols, in accordance with MIL-HDBK-113
and MIL-HDBK-275 (see FIGURE 3). The lubricant symbols and interval symbols shall be
printed in separate vertical columns on the inner side of the point names. These columns shall be
headed by the words "LUBRICANT" AND "INTERVAL". Those lubrication points which are
serviced or lubricated by checking level, replenishing lubricant, or draining and refilling shall be
indicated by the lubricant's symbol at the point on the illustration which is designated for
replenishing or refilling. The amount of lubricant required shall be given either in the point note
or in the "Capacity" column of the table, if applicable.
