CLEANING AND PRESERVATION OF LARGE COMPLEX EQUIPMENT THAT WILL NOT BE STORED

"STANDBY" AND IS OF SUCH SIZE AND/OR DESIGN THAT DISASSEMBLY IS NECESSARY PRIOR TO

MOVING

a. This type of equipment shall not be reassembled for the purpose of timing and alignment. It is necessary

that cleaning and preservation be accomplished without any delay between the two operations.

The following procedures may be used as a guide for preservation of large, complex equipment:

(1) Matching surfaces. Assemblies removed from the basic machine shall be cleaned in accordance with

MIL-P-116 process C-3 as described in paragraph 2-2. All cleaned areas shall be dried by either drying procedure D-1 or

D-4 which is detailed in paragraph 2-3. Immediately after drying, all cleaned surfaces shall be preserved with

preservative P-2, grade 2, of table 2-1.

(2) High-speed spindle bearings. It is unlikely that this type of assembly would be found on large complex

equipment. If high-speed spindle bearings are part of this equipment, they shall be preserved/filled with preservative oil

P-9, of table 2-1 and plugged to prevent spillage during handling.

(3) Gear housings. Thoroughly coat the mechanisms and all areas of the reservoir with preservative oil P-

10, grade 30, of table 2-1. This may be accomplished by spraying or any other suitable method.

(4) Hydraulic systems. Apply a thorough coating of hydraulic oil specified in the operators manual, on all

operating mechanisms in the hydraulic system. This may be accomplished by any suitable method of preservative

application. If this fluid is not available, use preservative oil P-15 conforming to MIL-H-5606 or MIL-H-6083.

(5) Self-contained lubricators. Fill all self-contained lubricators to operating level with preservative oil P-

10, grade 30, of table 2-1.

(6)

Grease fittings. Charge all grease fittings with preservative grease P-l 1 of table 2-1.
