OVERTEMPERATURE INDICATORS
Power is supplied to the transmission
through two
main drive shafts. Each shaft
has a flexible splined coupling at either
end, which
allows for variations in alignment
caused by normal motions of the
transmission. The dynamically balanced
shafts pass through the forward firewall
inside quick-disconnect baffle assemblies
which maintain the required isolation of the
engine compartment. Overtemperature
indicators are found on each coupling, and
will change color if the coupling has
exceeded operational limits.
