00:00:00,000 --> 00:00:02,417
Replace the brake shoe as follows:

2
00:00:02,417 --> 00:00:07,625
1. Chock at least two sets of truck wheels to prevent the locomotive from rolling in either direction.

3
00:00:07,625 --> 00:00:13,583
2. Release the hand brake, if set, and allow time for the truck wheels to seat against the wheel chocks.

4
00:00:13,583 --> 00:00:20,083
3. With the locomotive secure, locate and close the truck air cut-out cock on the underside of the locomotive frame.

5
00:00:20,083 --> 00:00:27,292
4. Move the brake shoe as far as possible from the wheel tread, then remove the retaining key and worn brake shoe from the brake head.

6
00:00:27,292 --> 00:00:34,208
5. Install a new shoe in the brake head, line-up the keyway, and then drive the retaining key to seat tight in the keyway.

7
00:00:34,208 --> 00:00:37,083
6. Check the brake shoe for a tight fit in the brake head.

8
00:00:37,083 --> 00:00:43,708
7. Adjust the manual slack adjuster as required, then reinstall any pins that were removed and lock them into place.

9
00:00:43,708 --> 00:00:46,333
8. Open the truck air cut-out cock.

10
00:00:46,333 --> 00:00:48,750
Adjust the brake system as follows:

11
00:00:48,750 --> 00:00:53,833
1. Chock at least two sets of truck wheels to prevent the locomotive from rolling in either direction.

12
00:00:53,833 --> 00:00:59,917
2. Release the hand brake, if set, and allow time for the truck wheels to seat against the wheel chocks.

13
00:00:59,917 --> 00:01:06,375
3. With the locomotive secure, locate and close the truck air cut-out cock on the underside of the locomotive frame.

14
00:01:06,375 --> 00:01:12,000
4. To adjust the brake system, lift and rotate the pin retainer and remove the slack adjuster pin.

15
00:01:12,000 --> 00:01:23,500
5. With the piston rod fully retracted, adjust the slack adjuster to provide a minimum clearance of 0.75 inches (19 mm) between the brake shoe and the wheel.

16
00:01:23,500 --> 00:01:28,542
6. Replace the slack adjuster pin and rotate the pin retainer in place over the pin.

17
00:01:28,542 --> 00:01:32,000
7. Check adjustments and the brake clearance at all other truck wheels.

18
00:01:32,000 --> 00:01:39,708
8. Open the truck air cut-out cock to supply air pressure to the brake system, then check for proper operation of the adjusted air brakes.

19
00:01:39,708 --> 00:01:42,125
Traction Motor Nose Suspension

20
00:01:42,125 --> 00:01:46,792
Inspect each suspension assembly for defective rubber mounting bushings.

21
00:01:46,792 --> 00:01:55,625
If the mounting bushings are worn, the bushing rubber is extruded from the cast link, or appears damaged in any way, replace the suspension assembly.

22
00:01:55,625 --> 00:01:59,333
Also, check for loose or missing mounting hardware.

23
00:01:59,333 --> 00:02:01,375
Side Bearer Inspection 

24
00:02:01,375 --> 00:02:03,833
Inspect the side bearers as follows:

25
00:02:03,833 --> 00:02:08,458
Ensure that the side bearer is centered under the locomotive side bearer pad.

26
00:02:08,458 --> 00:02:13,625
Inspect for evidence of motion between the side bearer and the locomotive side bearer pad.

27
00:02:13,625 --> 00:02:19,208
Inspect the side bearers for extreme wear or severe separation of rubber and steel laminations.

28
00:02:19,208 --> 00:02:23,375
Replace any defective or displaced side bearers.
