00:00:00,000 --> 00:00:05,042
Typical steps to remove the traction motor combo from the high adhesion truck are as follows:

2
00:00:05,042 --> 00:00:12,833
<b>Note:</b> The steps in this demonstration are applicable to both AC and DC traction motors, unless mentioned otherwise.

3
00:00:12,833 --> 00:00:17,375
The AC traction motor has been used to depict the steps in this demonstration.

4
00:00:17,375 --> 00:00:27,958
<b>Warning:</b> Disconnect the Multiple Unit (MU) jumper cables connecting the locomotive being serviced to any other equipment prior to performing any maintenance tasks.

5
00:00:27,958 --> 00:00:32,208
 Hazardous voltages may be present between interconnected units. 

6
00:00:32,208 --> 00:00:38,667
Failure to disconnect the MU jumper cables from the locomotive being serviced may result in injury or death.

7
00:00:38,667 --> 00:00:49,208
<b>Warning:</b> To ensure the safety of personnel, before proceeding, ensure that the truck and locomotive are securely supported and that the electrical power to the traction motors is OFF.

8
00:00:49,208 --> 00:00:57,250
<b>Warning:</b> On AC locomotives, capacitors in the inverter circuits may not be fully discharged and may contain lethal voltages.

9
00:00:57,250 --> 00:01:06,708
Before performing any maintenance on a traction motor or traction motor power cables, open the auxiliary cab door and raise the barrier bar to the vertical position.

10
00:01:06,708 --> 00:01:12,417
Raising the barrier bar closes the Capacitor Discharge Switch (CDS).

11
00:01:12,417 --> 00:01:20,458
Wait until all lights on the Capacitor Discharge Indicator (CDI) are extinguished before proceeding with any maintenance.

12
00:01:20,458 --> 00:01:26,083
1. Position the traction motor combo to be removed over a single-axle drop table.

13
00:01:26,083 --> 00:01:34,833
<b>Note:</b> If the axle to be removed is at either end of the truck, support the truck frame with suitable blocks to prevent it from tilting.

14
00:01:34,833 --> 00:01:47,792
2. Set the locomotive wheel brakes and chock the wheels on the truck not being worked on, then manually release the brakes on the wheels of the traction motor combo to be removed by closing the cut-out cock in the air line for that truck.

15
00:01:47,792 --> 00:01:55,208
<b>Note:</b> Ensure that all traction motor leads and connection cables are properly marked to ensure correct reconnection.

16
00:01:55,208 --> 00:02:07,333
3. Disconnect all power cables and the motor ground cable of the traction motor combo to be removed from the truck, then secure the cables to prevent damage during traction motor combo removal.
