High Oil Pressure Transmitter:
B

A
The electrical oil pressure gauge transmitter
(A) is located at the front of the crankcase in
the gallery line below the number 1 right
cylinder.
This sealed transmitter consists of
a threaded plate to which a diaphragm, a
radially notched spring, and an overload
guard plate are crimped.
Electrical resistance
in the transmitter varies directly as the oil
pressure varies.
The resulting variation in
the current is transmitted to the electrical oil
gauge on the vehicle instrument panel.
Auxiliary Generator High Oil Pressure
Sending Switch
(Model 2DR only):
The auxiliary generator high oil pressure
sending switch (B) is located at the right
front of the crankcase in the “T” that mounts
the oil pressure gauge transmitter.
This
switch prevents simultaneous operation of
the main engine and auxiliary generating
systems.
