Maintenance and Service Parts
Over time, exposure to foreign chemicals and
particulate matter as well as prolonged operation
at extreme conditions may reduce the effectiveness
of the temperature detector. At such time,
AMOT Temperature Detectors can be restored to
original performance by replacing the fuse rod.
Please order a fuse rod assembly and the service
instructions using the part numbers, quantities and
descriptions in the service parts table below. Fuse

should be replaced if the crimp
section becomes loose. The life expectancy of
fuse rod assemblies is five (5) years, under normal
operating conditions and proper maintenance.
AMOT recommends that the overall safety
system be checked MONTHLY for proper
functioning by simulating an unsafe condition.
AMOT recommends maintenance, including
visual inspections, at the major overhaul of
the engine or YEARLY if lacquering of the lube
oil is observed. Excessive lacquering can
cause sticking which impairs operation.
To test fuse rods, heat a mixture of 50% glycol and
50% water, stirring constantly. Place the fuse rod
in the heated liquid. Use a mercury thermometer
to check the temperature of the liquid. The
fuse rod assembly should trip within 4°F of the
temperature stamped on the bottom of the rod. DO
NOT attempt to resolder a eutectic fuse rod; the rod
expends upon firing.
AMOT designs and tests all its products to ensure
that high quality standards are met. For good
product life, carefully follow AMOT’s installation and
maintenance instructions; failure to do so could
result in damage to the equipment being protected
or controlled.
