TM 9-2815-220-24 THEORY OF OPERATION 0004 00 TRANSMITTERS (Continued) High Oil Pressure Transmitter: B A 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 âTâ that mounts the oil pressure gauge transmitter. This switch prevents simultaneous operation of the main engine and auxiliary generating systems. END OF WORK PACKAGE WP 0004 00-29 (30 blank)
