LOCATION AND DESCRIPTION OF MAJOR COMPONENTS
WATER MANIFOLD
Three sections of cast-iron piping and two steel tubes, containing thermostat, temperature gage
sending unit, high-temperature engine shutdown switch, and shutter control valve. The water
manifold serves as a passage for hot coolant that has circulated through the cylinder block and
cylinder heads to be delivered to the radiator.
ENGINE COMPRESSION BRAKE
Three separate units, one mounted above each of three rocker arm housings. They contain elec-
trically operated solenoids that open engine exhaust valves near the top of the compression stroke.
The engine brake system is energized from a dash-mounted switch. The electrical solenoids are
supplied with power through a switch mounted on the fuel pump and controlled by the throttle lever.
ROCKER HOUSING COVER
Three separate aluminum covers, used to cover each rocker arm housing. The front rocker housing
cover contains the crankcase breather, oil filler opening, and cap. The center and rear rocker
housing covers are plain.
