CHAPTER 4
ORGANIZATIONAL MAINTENANCE INSTRUCTIONS
Section I. SERVICE UPON RECEIPT OF MATERIEL
4-1. Inspecting and Servicing Equipment
a. Inspection.
(1) Inspect the identification plates for positive
identification of the equipment.
(2) Make a thorough inspection of the
pumping assembly and tanks for damage which
may have occurred during shipment,
(3) Check the equipment against the packing
list to make certain all items are accounted for and
in serviceable condition.
(4) Inspect the components for loose or
missing mounting hardware and loose connections.
(5) Turn the engine with the starter rope to
make sure all moving parts are free.
b. Servicing.
(1) Lubricate the engine in accordance with
the current lubrication order.
(2) Perform preventive maintenance checks
and services (para 4-9).
4-2. Installation.
a. General. The tank and pump unit is designed
for mounting in trucks. Three types of blocking
frames have been devised to prevent shifting of the
tank and pump unit during movement, particularly
on rough terrain. Section 1 (fig. 4-1) is used in the
5-ton. 6 x 6 cargo truck M-54 and prevents
longitudinal movement. Sections 2 and 3 are also
used in the M-54 cargo truck, and in the 2 1 / 2-
ton, 6 x 6 cargo trucks M-35 and M-211. They are
designed to prevent side movements of the tank and
pump unit. Construct frames in empty truck bed
for ease in measuring lengths of lumber and
assembling frames. Install tank and pump unit
between the frames when the frames are con-
structed. Complete installation instructions are
given in b below. Dimensions shown in figure 4-1
must be altered slightly to take care of individual
differences in dimensions of equipment. Before
constructing blocking frames, check measurements
of the track bed and tank skids to determine
centerline for mounting of tanks. The tanks must
be centered so that section 2 blocking frames will fit
properly. Also determine centerline of pumping
assembly so that section 3 blocking frames will fit
properly. As an alternate method, tank and pump
unit may be temporarily centered in truck bed and
an outline made along sides of tank skids and
pumping assembly to check dimensions used in
constructing blocking frames.
