STARTING THE ENGINE
The WDG4/WDP4 Locomotive is equipped with dual STARTOR MOTORS
for cranking the Diesel Engine, at left side near the Engine Ring gear. Diesel
Engine fuel oil must be circulated through fuel system before the Engine
starts. When the FP/ES switch is held in PRIME (left), the Locomotive
computer starts the fuel Pump motor. After ensuring the return fuel sight
glass clear without bubbles (approximately 20 seconds), turn the FP/ES
switch to START (right) position. These STARTOR MOTORS run with
Battery supply available on Locomotive to start the Diesel Engine.
While cranking the Diesel Engine, ensure the following:
1. Ensure that Throttle Handle of both control console is in IDLE,
Reverser handle at center and RUN/ISOLATE Switch is in ISOLATE
position.
2. Ensure there is sufficient oil level of Compressor Oil, Engine Lube Oil
and Governor Oil.
3. Ensure there is sufficient Coolant Water level in the water tank
(Engine dead – Full).
4. Ensure that no one is working on the Engine, Generator Room,
Compressor Room etc. and all doors are closed.
5. Ensure that the MU Engine Stop button is in RUN position (For RUN
press Green portion inside).
6. Ensure that the engine Over Speed Mechanism (OST) is reset.
7. Ensure that the Governor Low Lube Oil Button (LLOB) is reset.
8. Ensure that the Crankcase (oil pan) pressure and Low water
pressure detector reset buttons are reset (pressed inside). If any
button is found ejected, press and hold it for 15 seconds immediately
after Engine starts.
