Preparation of Jaw Crusher for Shipment
a. General. Detailed instructions for the preparation of the jaw crusher for domestic shipment are outlined within
this paragraph. Preservation will be accomplished in sequence that will not require the operation of previously preserved
components.
b. Inspection. The jaw crusher will be inspected for any unusual conditions such as damage, rusting, accumulation
of water, and pilferage. Inspection shall be completed as outlined on the quarterly preventive maintenance Services. All
deficiencies will be recorded on DA Form 2404 (Equipment Inspection and Maintenance Worksheet).
c. Cleaning and Drying. Clean and dry the jaw crusher by an approved method. Approved methods of cleaning
and drying, types of preservatives, and methods of application are de- scribed in TM 38-230.
d. Painting. Paint all surfaces when the paint has been removed or damaged. Refer to TB ENG 60 for detailed
cleaning and painting instructions.
e. Depreservation Guide. A properly annotated DA Form 2258 (Depreservation Guide of Engineer Equipment) will
be completed con-currently with preservation for each item of mechanical equipment. Any peculiar requirements will be
outlined in blank spaces 27 through 33. The completed depreservation guide will be placed in a waterproof envelope,
marked DEPRESERVATION GUIDE, and fastened in a conspicuous location on or near the operator's controls.
f. Cooling System. Determine that cooling system is filled to the proper level with a clean solution of 50 percent
water to 50 percent ethylene glycol conforming to specification O-A-548.
Note. It is not necessary to drain and refill cooling system if the solution is clean and checks to a -25 F. If
temperatures below -25 F. are expected, antifreeze conforming to Specification MILC-11755 will be used in its
undiluted condition.
g. Lubrication System. If level of lubricant is low and no leaks are apparent, refer to the lubrication chart and fill
with the specified lubricant. Operate the engine at a fast idle until lubricant has been circulated throughout the system.
h. Sealing of openings. Openings that will permit the direct entry of water into the interior of engine-driven
equipment, electric motors, engine, etc., shall be sealed with pressure-sensitive tape conforming to specification PPP-T-
60, type 111, class 1.
i. Fuel Tank. If the fuel tank is empty it will be fogged with type P-10, grade 2, engine preservative oil, conforming
to MIL-L-21260. It is not necessary to drain fuel tank for domestic shipment.
j. Hydraulic Control System, Except Hydraulic Brake.
(1) Fully retract the piston as far as the linkage will permit and secure.
(2) Coat exposed portion of the hydraulic piston rods and operate valve controls with type P-6 preservative
conforming to specification MIL-C-11796, class 3. If preservative is not available, Automotive and Artillery Grease
(GAA) may be used.
(3) Wrap the preserved portion with type 1, class 2, grade A, barrier material conforming to MIL-B-12L.
