Heat
Air temperatures of up to 120°F are bad enough, but the ground absorbs the heat
and can get as hot as 165°F!
Those temperatures are extremely hard on rubber parts. Heat makes track shoes
soft and weakens their resistance to sharp rocks and plant spines. High temperatures
also increase rubber/metal separation on roadwheels.
Pay special attention to shoes and roadwheels during PMCS. Replace pads that
are severely damaged or worn down to the grouser.
Roadwheels with tread separation on each side up to the entire circumference
of the wheel that is 1 inch or wider for M1-series tanks and M88A1/A2 recovery
vehicles,
3
/
4
inch or wider for M113-series FOV, or
1
/
2
inch or wider for M2/M3-
series Bradley, M109-series howitzers and MLRS should be replaced.
Also, replace roadwheels that have chunking extending across half
the width or more of the outer rubber surface in one or more spots.
