PREPARATION FOR USE
Section I. TRAILER ASSEMBLIES AND AUXILIARY SYSTEMS.
a. This chapter contains the information required
to prepare the METS trailer assemblies and auxiliary
systems for use and provides instructions for installation
of all engine accessories used for engine testing. The
preparation procedures are recommended at initial use
and after prolonged storage or replacement of major
components. Procedures pertinent to operation,
servicing and lubrication and repair or replacement are
presented in other chapters of this technical manual;
reference will be made to the applicable chapter when
b. Each trailer assembly is shipped completely
assembled. Prior to operation of the system, an initial
inspection is required to ascertain that damage to the
equipment has not occurred in transit or handling.
Following this inspection, the trailers must be towed to
the operation site, positioned, and interconnected. The
engine to be tested is then equipped with the
appropriate engine accessories and towed to the test
site by use of the engine test dolly assembly and a
prime mover. The dolly and engine are secured to the
deck of the test trailer assembly and interconnected to
the auxiliary systems and instrumentation. Following
instrumentation is made to ensure the integrity of the
accomplished, a checkout is made prior to firing the
engine to complete the preparation of the system for
2-2. Inspection at Receipt of Equipment.
To ensure that in-transit, towing, or long-term storage
damage has not occurred, a visual inspection of METS
is required prior to use. If damage is found, record the
extent of the damage on the appropriate form in
accordance with AR 735-11 and notify the Maintenance
Officer. Repair or replace the damaged component as
specified in chapter 6 of this manual. Accomplish
inspection in accordance with the following:
a. Check the sheet metal and structural members
of the trailer assemblies for dents, scratches, security of
attachment, and condition of paint for obvious in-transit
damage. Check to
ensure that all red reflector glass in intact and secure.
b. Check the exterior lights on the test trailer
assembly for damage and security of installation.
c. Check to ensure that the glass in all gages,
meters, and indicators in the control cab submodules,
data acquisition assembly, portable oil unit, hydraulic
start system, and engine accessories is intact and
d. Check all hydraulic tube and hose assemblies,
bulkhead fittings, and quick-disconnects for dents,
cracks, and loose or damaged sleeves. Remove the
protective plugs and caps from plumbing fittings and B-
nuts and inspect for chipped, crossed, cracked, and
broken or truncated threads.
e. Check installed connectors and the plugs and
connectors of cable assemblies for broken or damaged
shells and stain reliefs. Check insulation and sleeving
for obvious damage. Check the legibility of the part
numbers and reference designation markings on the
sleeves of each cable assembly.
f. Check to ensure that the control cab module
door will open and close properly and remain in the
instrumentation sub-module doors will open and will
latch when in the closed position.
g. Check the security of the dust caps on all
external connectors and quick-disconnect couplers.
h. Check the pan interior of the cooling tower
module for damage and presence of foreign matter.
i. Check the fan assemblies, air inlet screens, and
the motors in the cooling tower module for damage and
j. Check to ensure that the removable steel
branches and plastic spray nozzles of the sprinkler
system in the cooling tower module are securely
k. Check to ensure that the removable wet deck
surface and sectional eliminators in the cooling tower
module are securely mounted.
