(2) Application paint. Paint should be applied by spraying, but may be applied by brushing. The paint

coating shall be uniform and complete, without sags, runs, blisters, or holidays. Holidays are spots accidentally left

uncovered on coated or painted surfaces.

(3) Painting requirements. One coat of Lacquer resisting, lust-inhibiting, synthetic, coating Primer

conforming to TT-P-664, shall be applied to all areas not already prime coated. After the primer is dry, two coats of gloss

alkyd enamel, conforming to TT-E-489 shall be applied. The first coat should be thoroughly dry, prior to application of

the second coat. For touch-up purposes, the enamel shall match the existing color of the item. When complete

repainting is required the color shade shall be medium gray, number 16187, in accordance with FED-STD-595.

Drive belts. All drive belts shall be either removed from the equipment or have the tension released.

(1) All removed belts shall be cleaned by wiping with clean dry cloth. If a glazed surface has formed on

the pulley side of the belt, it may be removed with a cloth lightly dampened with a 50-50 percent solution of alcohol and

glycerin or with cleaning solvent.

(2) All removed belts shall be packed in accordance with MIL-P-116, method III and secured to the

equipment. All drive belts shall be identified with the drive units to which they belong.

(3) Clean the faces or grooves of all ferrous metal pulleys with cleaning solvent, and dry in accordance

with paragraph 2-3 process D-1 or D-4. The faces or grooves of the metal pulleys shall be coated with primer conforming

to TT-P-664, after cleaning.

v. Packings and wipers. Various types of packing and wipers used in connection with hydraulic, lubricating,

and pneumatic systems have a destructive effect on metal surfaces when maintained in stationary contact for extended

periods. Because of the presence of residual tanning and finishing chemicals, leather packing may cause pitting. Other

types, due to their moisture-absorbing qualities, cause corrosion at the point of contact with metal surfaces. To alleviate

these conditions all packing and wipers shall be thoroughly saturated with preservative oil P-10, grade 30, of table 2-1.

(1) Organic type packing in coolant, lubricating, hydraulic, and other liquid carrying systems shall not be

removed unless it is necessary for replacement purposes.

(2) All way wipers shall be removed and replaced with new ones. New way wipers shall be thoroughly

saturated with preservative oil P-10, grade 10, of table 21.
