00:00:00,000 --> 00:00:06,292
The traction motor nose suspension provides support for the traction motor between the motor and the truck frame.

2
00:00:06,292 --> 00:00:13,125
There is one traction motor nose suspension assembly connecting each traction motor nose to the truck frame.

3
00:00:13,125 --> 00:00:16,583
There are two types of traction motor nose suspension.

4
00:00:16,583 --> 00:00:25,792
The AC Traction Motor uses a "dog bone" shaped suspension, and the DC Traction Motor uses a laminated rubber-steel stack suspension.

5
00:00:25,792 --> 00:00:31,542
Let’s first discuss how to inspect and replace an AC traction motor nose suspension.

6
00:00:31,542 --> 00:00:36,125
Inspect each suspension assembly for defective rubber mounting bushings.

7
00:00:36,125 --> 00:00:46,083
If the mounting bushings are worn, bushing rubber extrudes from the cast link, or bushing rubber appears damaged in any way, replace the suspension assembly.

8
00:00:46,083 --> 00:00:50,042
Also, check for loose or missing mounting hardware.

9
00:00:50,042 --> 00:00:57,750
<b>Note:</b> A mounting bushing is worn if there is any clearance between the crossbar and cast link because of missing rubber.

10
00:00:57,750 --> 00:01:08,708
<b>Caution: </b>Remove the suspension link by using a special socket tool to remove the CAMCAR bolts or by cutting the CAMCAR bolts with a torch or hydraulic splitter.

11
00:01:08,708 --> 00:01:16,958
If a torch is used, form a shield to protect the rubber parts of the suspension link from heat damage, and use extreme care.

12
00:01:16,958 --> 00:01:20,875
Do NOT reuse the bolts, washers, or nuts.

13
00:01:20,875 --> 00:01:26,833
Do NOT replace CAMCAR bolts and nuts with ordinary fastener bolts and nuts.

14
00:01:26,833 --> 00:01:34,458
Bolts and nuts may loosen during locomotive operation and cause traction motor failure or other equipment damage.

15
00:01:34,458 --> 00:01:40,667
<b>Note: </b>Refer to the applicable Parts Bulletin for recommended replacement parts.
