14
00:01:24,583 --> 00:01:32,333
13. Raise the locomotive platform clear of the truck with jacks or a crane, or lower the truck on a drop table.

15
00:01:32,333 --> 00:01:43,125
14. After the truck is removed from under the locomotive, cover the truck center pin bearing and traction motor openings to prevent contamination with dirt and other foreign materials.

Steerable Truck Installation

17
00:01:45,458 --> 00:01:50,125
1. Space the trucks for a truck center-block to center-block spacing.

18
00:01:50,125 --> 00:01:56,500
2. Remove the temporary dust covers from the traction motor air duct and center pin bearing openings.

19
00:01:56,500 --> 00:02:04,667
3. Inspect the traction motor air ducts between the locomotive platform and the truck and replace any air ducts that are cracked or torn.

20
00:02:04,667 --> 00:02:12,000
4. Coat the center pin on the underside of the locomotive platform with grease before lowering the platform onto the truck.

21

24
00:02:26,292 --> 00:02:33,292
8. Install the lateral dampers to the platform, with the shorter bolt at the bottom, and torque the bolts.

25
00:02:33,292 --> 00:02:37,708
9. Install the yaw dampers to the platform and torque the bolts.

26
00:02:37,708 --> 00:02:42,292
10. If installing the long-hood end truck, connect the hand brake chain.

27
