TIRES AND WHEELS MAINTENANCE.
Disassembly.
Disassemble the wheels and tires as illustrated in
a.
b.
Cleaning, Inspection, and Repair.
(1)
Scrape dirt from wheels.
(2)
Inspect studs for wear, cracks, stripped threads, burrs, and
any other damage.
(3)
Damage will occur to the wheel if the mounting nuts become
loose, resulting in excessive wear on the wheel mounting holes.
If the wheel mounting holes have become enlarged because of
excessive wear, replace the wheel.
(4)
Inspect tires for cuts, bruises, wear, deteriorated cords, and
other obvious damage.
(5)
Inspect wheel lockrings for cracks, breaks, or bends. Replace
as necessary.
(6)
Replace any excessively worn or defective tires, tubes, wheels,
or related components.
(7)
Clean the rubber flaps and inspect for defects. Replace a de-
fective flap.
(8)
For more detailed repair of tires, refer to TM 9-2610-200-20.
c.
Tire Matching. Measure the circumference of the tires of one dual
assembly at the center of the tread. Tires must match within three-
quarter inch of their circumference and one-quarter inch of their
diameter. Always mount the larger of the dual tires on the outside
wheel.
d.
Reassembly.
Reassemble the wheels and tires as illustrated in fig-
ure 19-1.
Installation.
e.
(1) Place the inner wheel on the hub studs and secure with the
five inner wheel nuts. Alternately tighten the nuts on the
opposite sides to assure tightness. Place the outer wheel over
the inner wheel nuts in such a manner that the valve stem of
the outer tire is as near to 180 from the inner valve stem as
possible, and that the holes in the body of the inner and outer
wheel are lined tip. Install the five outer wheel nuts and tight-
en alternately.
(2) Lower the trailer and release brakes.
