Truck Alignment Verification

2
00:00:02,000 --> 00:00:05,583
1. Ensure that the locomotive is on a straight, level track.

3
00:00:05,583 --> 00:00:12,583
2. Release the brakes on the truck being aligned by closing the truck air brake cut-out cock and bleeding air from the brake cylinders.

4
00:00:12,583 --> 00:00:16,292
3. Check the axle distance between the center and each end axle.

00:00:16,292 --> 00:00:18,958
Wheel Lateral Alignment Verification

6
00:00:18,958 --> 00:00:22,458
1. Align the end axle wheels with the truck frame as follows:

7
00:00:22,458 --> 00:00:33,458
a. Install 5.125 inch (13.018 cm) blocks to the journal box tees on the non-gearcase side of both end axles.

8
00:00:33,458 --> 00:00:45,042
b. Install airbags between the truck frame and the wheel on the non-gearcase side of the end wheel sets, then apply air to the airbags and move each wheel set until there is contact between the blocks and the truck frame.

9
00:00:45,042 --> 00:00:50,708
2. Use wedges to block the end axles in respect to the frame and remove the airbags from the end axles.

10
00:00:50,708 --> 00:00:54,750
3. Align the center axle wheels with the end axle wheels as follows:

11
00:00:54,750 --> 00:01:01,917
a. Use a long straight edge or a wire stretched tight against the backside face of the non-gearcase wheels of both the end axles.

12
00:01:01,917 --> 00:01:06,875
b. Use airbags to align the center axle wheel with the straight edge or wire.

13
00:01:06,875 --> 00:01:20,708
4. If the center axle wheel is not aligned with the straight edge or wire, loosen the CAMCAR bolt connections on the two inter-motor links at traction motor positions 1, 2, 5, and 6 to allow the center axle to be laterally aligned.

14
00:01:20,708 --> 00:01:27,583
5. If the CAMCAR bolts are not already loosened and hand-tightened, remove and install new CAMCAR bolts one at a time.

15
00:01:27,583 --> 00:01:33,417
6. Hand-tighten the nuts and tag the bolts as loose, then repeat steps 3a and 3b.
