Loadbearers

16
00:01:25,750 --> 00:01:28,875
Inspect the loadbearers as follows:

17
00:01:28,875 --> 00:01:33,792
1. Ensure that the loadbearer is centered under the locomotive loadbearer pad.

18
00:01:33,792 --> 00:01:39,208
2. Inspect for evidence of motion between the loadbearer and locomotive loadbearer pad.

19
00:01:39,208 --> 00:01:45,625
3. Inspect loadbearers for extreme wear or severe separation of rubber and steel laminations.

20
00:01:45,625 --> 00:01:50,167
Replace any defective or displaced loadbearers as follows:

21
00:01:50,167 --> 00:01:52,292
1. Remove the safety hooks.

22
00:01:52,292 --> 00:01:57,042
2. Jack up the locomotive high enough so that the loadbearer can be removed.

23
00:01:57,042 --> 00:02:01,000
3. Remove and replace ALL four loadbearers as a set.

24
00:02:01,000 --> 00:02:03,542
Lateral and Yaw Shock Absorbers

25
00:02:03,542 --> 00:02:10,500
Inspect each lateral and yaw hydraulic shock absorber for leakage or defective rubber mounting bushings.

26
00:02:10,500 --> 00:02:14,583
Replace lateral and yaw shock absorbers as follows:

27
00:02:14,583 --> 00:02:20,625
1. Remove all four bolts and associated washers and nuts securing the shock absorber.

28
00:02:20,625 --> 00:02:24,042
2. Remove and discard the hydraulic shock absorber.

29
00:02:24,042 --> 00:02:26,500
3. Install new shock absorber.

36
00:02:52,083 --> 00:02:54,042
3. Install new snubbers.

37
00:02:54,042 --> 00:02:59,542

Coil Springs

39
00:03:01,250 --> 00:03:10,458
Visually inspect each coil spring for breaks, cracks, vertical wear flats, deep nicks, gouges, or other signs of damage.

40
00:03:10,458 --> 00:03:18,958
If visible damage to a coil spring indicates that the useful life or performance of the spring may be limited, replace the spring.

41
00:03:18,958 --> 00:03:25,000
Remove the coil springs as directed in the Traction Motor Removal section of this module.

42
00:03:25,000 --> 00:03:26,625
Safety Hooks

43
00:03:26,625 --> 00:03:30,167
Inspect the safety hooks for proper clearances.

44
00:03:30,167 --> 00:03:36,000
If the safety hooks do not meet clearances, identify and replace the defective hooks.

45
00:03:36,000 --> 00:03:38,667
