Bell Crank Assembly Inspection

2
00:00:02,250 --> 00:00:08,583
Inspect the bell crank assembly for minimum clearance between the bell crank and the traction cap.

3
00:00:08,583 --> 00:00:19,167
Use a feeler gauge to check that there is a minimum clearance of 0.06 inches (1.5 mm) between the bell crank and the traction cap.

4
00:00:19,167 --> 00:00:27,625
If the clearance is less than 0.06 inches (1.5 mm), the thrust washers might be defective.

5
00:00:27,625 --> 00:00:29,542
Thrust Washer Replacement

6
00:00:29,542 --> 00:00:36,875
1. Remove the retainer thrust washer and spacer by unscrewing the four bolts and save the hardware for re-installation.

7
00:00:36,875 --> 00:00:40,042
2. Remove and discard the first thrust washer.

8
00:00:40,042 --> 00:00:47,417
3. Remove the four bolts and washers from the retainer lower bearing cap and save the hardware for re-installation.

9
00:00:47,417 --> 00:00:51,167
4. Replace the second thrust washer with a new thrust washer.

10
00:00:51,167 --> 00:01:06,333
5. Install the retainer lower bearing cap and the four washers and the four bolts on opposite corners, then torque the bolts to 88 ± 5 lb.-ft. (40 ± 2.3 Nm).

11
00:01:06,333 --> 00:01:10,958
6. Install a new thrust washer on top of the retainer lower bearing cap.

12
00:01:10,958 --> 00:01:15,542
7. Install the thrust washer spacer in the center of the thrust washer.

13
00:01:15,542 --> 00:01:30,625
8. Install the thrust washer retainer on top of the thrust washer spacer using four washers and four bolts, then torque the bolts to 58 ± 3 lb.-ft. (26 ± 1.4 Nm).

14
00:01:30,625 --> 00:01:34,417
Visual Inspection of the Traction Link and the Center Link

15
00:01:34,417 --> 00:01:39,958
Visually inspect the traction link and the center link for missing nuts and bolts.

16
00:01:39,958 --> 00:01:42,917
Apply new fasteners if they are missing.

17
00:01:42,917 --> 00:01:45,875
Visual Inspection of the Wing Plate Assembly

18
00:01:45,875 --> 00:01:51,375
1. Visually inspect the wing plate assembly for missing hardware fastened on links.

19
00:01:51,375 --> 00:01:59,042
2. Visually inspect the wing plate shear pads and rubber bushings for cracks or delamination of the bonded rubber and metal.

20
00:01:59,042 --> 00:02:04,250
3. Inspect the wing plate pins for indications of wear and/or clearance.

21
00:02:04,250 --> 00:02:11,375
4. Ensure that the shear pad is properly seated in the wing plate, the reaction arm, and the reaction arm cover.

22
00:02:11,375 --> 00:02:16,000
Visual Inspection of the Equalizer Arm and the Equalizer Bar

23
00:02:16,000 --> 00:02:22,667
1. Check the match marks on the equalizer arm to verify that the arm has NOT moved relative to the bell crank.

24
00:02:22,667 --> 00:02:28,833
2. Visually inspect the equalizer bar rubber bushing for swelling, delamination, and wear.

25
00:02:28,833 --> 00:02:33,583
3. Visually inspect the equalizer bar for any signs of wear or cracking.

26
00:02:33,583 --> 00:02:40,625
4. Visually inspect the equalizer bar for missing nuts and bolts and apply new fasteners, if missing.

27
00:02:40,625 --> 00:02:42,750
Equalizer Bar Replacement

28
00:02:42,750 --> 00:02:45,417
1. Remove the equalizer bar assembly.

29
00:02:45,417 --> 00:02:48,500
2. Dismantle the equalizer bar assembly.

30
00:02:48,500 --> 00:02:56,083
3. Assemble the subassembly by using a new equalizer bar and re-using the damper support bracket and mounting hardware.

31
00:02:56,083 --> 00:03:03,167
4. Connect the damper support bracket to the new equalizer bar, then torque the three bracket mounting bolts.

32
00:03:03,167 --> 00:03:06,000
5. Install the equalizer bar assembly.

33
00:03:06,000 --> 00:03:08,875
Safety Hook Inspection and Replacement

34
00:03:08,875 --> 00:03:12,625
Inspect the safety hooks for proper clearances.

35
00:03:12,625 --> 00:03:19,250
If the safety hooks do not meet clearances, identify and replace the defective hooks.
