<b>Caution:</b> The DC armature must be locked when the motor is transported, other than from work station to work station during processing, to prevent damage to the bearings caused by shock and vibration.

2
00:00:12,625 --> 00:00:26,875
<b>Note:</b> A shipping kit, Part number 41B537934G1, may be ordered that contains two long bolts (with heads painted yellow), two jam nuts, and a caution tag.

00:00:26,875 --> 00:00:33,458
However, when a complete traction motor combo is shipped, the armature is locked using only one bolt.

4
00:00:33,458 --> 00:00:39,792
The armature locking bolt is installed on the commutator end of the DC traction motor.

5
00:00:39,792 --> 00:00:47,042
Typical steps to install the DC armature locking bolt on a DC traction motor combo are as follows:

6
00:00:47,042 --> 00:00:56,792
1. Remove one of the two 5/8-inch bolts that are diametrically opposite each other from the commutator end of the traction motor frame.

7
00:00:56,792 --> 00:01:01,833
2. Screw a jam nut onto one of the long bolts from the kit.

8
00:01:01,833 --> 00:01:08,917
3. Thread the long bolt into the traction motor frame until it bears on the commutator end cap.

9
00:01:08,917 --> 00:01:17,125
4. Torque the bolt to 30 lb.-ft. (41 Nm), then secure it with the jam nut.

10
00:01:17,125 --> 00:01:27,000
5. Place the regular bolt and washer into the bag, then tie the tag to the yellow locking bolt for shipment with the traction motor combo.

11
00:01:27,000 --> 00:01:34,667
<b>Caution:</b> To avoid commutator damage, do NOT attempt to rotate the armature with the locking bolt in place.
