b. Use e-inch rivnuts of appropriate length, and install the
rivnuts (dipped in the bonding agent specified in the
system specific MK-679/G shelter maintenance manual)
in the shelter bottom with the applicable rivnut heading
tool as instructed in paragraph 30 of the system specific
MK-679/G shelter maintenance manual.
c. Prepare a sheet aluminum alloy spacer 0.001-0.003 inch
thinner than the head of the rivnut.
Drilling and cutting operations create metal chips
which may enter the eyes. Eye protection is required.
d. Use the skid as a template to mark the spacer and drill
holes equivalent to the diameter of the rivnut head.
e. Position the spacer and skid and secure the spacer and
skid by tightening the mounting bolts into the rivnuts.
Figure 10-13. Corrosion Undercarriage of Shelter
f. Prime and paint the exposed aluminum alloy surfaces
per directions in MIL-DTL-14072 with application procedures
per Chapter 7 of this manual.
10.16 VAN AND TRAILER ATTACHMENT POINTS
(INCLUDING LIFT RINGS).
Drilling and cutting operations create metal chips
which may enter the eyes. Eye protection is required.
e. Use the skid as a template to mark the spacer and drill
holes equivalent to the diameter of the blind nut head.
f. Position the spacer and skid, and secure by tightening
the mounting bolts with lock washers and nuts into the
blind nuts.
g. Apply a fillet seal to the skid seams and a topcoat seal
over the mounting hardware.
10.15.2.2 Replacing Damaged Shelter Skids. Damaged
shelter skids secured with rivets must be removed and secured
with mounting bolts. Follow the procedures below when
replacing damaged shelter skids.
Lift, tow, and tie-down fittings are normally mounted on shelter
corners, on end walls, and on roof panels. The lift rings and
mounts are designed for lifting the complete shelter with internally
mounted and stowed equipment. Because of the severe
loads placed on all ring fittings, the ring, mounts, and attachment
hardware must be in good mechanical condition and
properly secured. If the rings are deformed or exhibit weld
cracks, they must be replaced by depot. The lift rings on the
C-E-M shelters are susceptible to corrosion due to the extreme
heavy pressure/stress applied to the rings when the shelters are
moved and setup in the field. The heavy use of the rings
causes the protective coating to crack allowing moisture to
enter and begin to initiate corrosion If the lift rings and fittings
exhibit rust or surface corrosion, but are otherwise sound, the
fitting should be cleaned to bare metal and refinished. Refer to
paragraph 3.13.3 and Table 3-9 in TO 35E4-1-162 for the
required paint system and apply it per procedures in Chapter 7
of this manual.
