00:00:00,000 --> 00:00:03,000
When inspecting the brush holders:

2
00:00:03,000 --> 00:00:08,000
Check for loose, broken, bent, or overheated pressure arms.

3
00:00:08,000 --> 00:00:13,250
Overheating will cause the arms to discolor and result in improper brush arm pressure.

4
00:00:13,250 --> 00:00:16,167
Annually verify brush arm force.

5
00:00:16,167 --> 00:00:27,208
If it is below 4.25-4.75 lbs. (1.93-2.15 kg), replace the brush holder.

6
00:00:27,208 --> 00:00:34,542
Ensure that the thumb loop on the coiled brush pressure spring is in position with the spring end placed into the detent.

7
00:00:34,542 --> 00:00:42,542
Inspect the brush holder mounting arrangement, and ensure the clamp pads are in place and tight against the brush holder stud.

8
00:00:42,542 --> 00:00:52,292
If they are not in place, locate the clamp pads and torque the clamp bolts to 16-18 lb.-ft. (22-24 Nm).

9
00:00:52,292 --> 00:00:55,500
Check the brush holder-to-collector ring clearance.

10
00:00:55,500 --> 00:01:09,708
If the clearance is not between 0.089 and 0.091 inches (2.2-2.3 mm), adjust the clearance as discussed in the Brush Holder and Stud Assembly Alignment section of this module.

11
00:01:09,708 --> 00:01:14,875
Inspect the brush holder assembly for broken connection straps or bus rings.

12
00:01:14,875 --> 00:01:24,292
Replace, if necessary, as discussed in the Brush Holder and Stud Assembly Removal and the Brush Holder and Stud Assembly Installation sections of this module.

13
00:01:24,292 --> 00:01:28,917
Check by hand the tightness of the bus ring to the brush holder bolts.

14
00:01:28,917 --> 00:01:36,250
If loose, torque the bolts to 22-24 lb.-ft. (30-33 Nm).
