POM 35.000.075 Revision 3 Page 27 d.
Ensure that tangs of capstan spring (18) are properly centered as follows:
1)
Rotate inertia mass (11) quickly clockwise and counterclockwise on shaft of leadscrew.
NOTE (1): If capstan spring (18) tangs are properly centered, the interval between pings will be relatively short, the audible sound will be faint, and the rotational travel between pings will be limited to a few degrees (approximately 5*).
NOTE (2): If capstan spring (18) tangs are improperly centered (only one tang, or neither, between clutch spring lips) the interval between pings will be several times longer, the audible sound will be louder, and the rotational travel between pings will be many degrees greater (approximately 30*).
2)
While maintaining a relatively constant rotational speed, listen for an audible
" ping" as the capstan spring tangs strike the clutch spring lips at the limits of travel. Listen also to the length of the interval between pings.
3)
Repeat proceeding Steps 7.2.5.11.d.1 and 7.2.5.11.d.2 until inertia mass (11) is properly installed.

Install inertia mass assembly (12) in accordance with the following instructions:
1 l
CAUTION
[
l I
l WHEN INSTALLED, BOTH TANGS OF CAPSTAN SPRING (17)i l MUST BE LOCATED IN SLOT OF INERTIA MASS SHELL, l
l BEIVEEN CLUTCH SPRING LIPS. SINCE INSTALLATION l l OF INERTIA MASS ASSEMBLY (12) IS A BLIND l
l PROCEDURE. PAY STRICT ATTENTION TO THE POLLOWING l l INSTRUCTIONS TO VERIFY PROPER INSTALLATION.
l l IMPROPER INSTALLATION OF INERTIA MASS ASSEMBLY l
l WILL CAUSE IMPROPER BRAKING ACTION OF THE l
l ARRESTOR DURING OPERATION.
I Rotate the torque carrier assembly (14) until a.
the tangs of the capstan spring (17) are pointing up.
b.
Visually align slot in shell of inertia mass assembly (12) so that tangs of capstan spring (17) are centered between lips of clutch spring of inertia mass assembly.
With bolt of torque carrier assembly (14) c.
centered in hub of inertia mass assembly (12), and tangs of capstan spring (17) visually centered between lips of clutch spring, carefully slide inertia mass assembly straight in until bottomed, d.
Verify that tangs of capstan spring (17) are properly centered as follows:
1)
Rotate inertia mass assembly (12) quickly clockwise and counterclockwise on bolt of torque carrier assembly (14).

i
POM 35.000.075 Revision 3 Page 42 NOTE (1): If capstan spring (17) tangs are properly centered, the interval between pings will be relatively short, the audible sound will be faint, and the rotational travel between pings will be limited to a few degree (approximately 5').
NOTE (2): If capstan spring (17) tangs are improperly centered (only one tang, or neither, between clutch spring lips) the interval between pings will be several times longer, the audible sound will be louder, and the rotational travel between pings will be many degrees greater (approximately 30').
2)
While maintaining a relatively constant rotational speed, listen for an audible
" ping" as the capstan spring tangs strike the clutch spring lips at the limits of travel. Listen also the length of the interval between pings.
3)
Repeat preceding steps (1) and (2) until certain that inertia mass (12) is properly installed.
12.
Secure inertia mass assembly (12) to bolt of torque carrier assembly (14) with new castellated (10) and new flat washer (2).
nut
- 13. Tighten castellated nut (10) against washer; then, rotate nut counterclockwise until next groove is aligned with cotter pin hole in bolt of torque carrier assembly (14).
14.
Install cotter pin (9) to retain caste 11sted nut I
I (10).
- 15. Secure dust cover (8) in bore of adapter nut (4),
or transition tube (5), with retaining ring (7).
f Make certain that retaining ring is properly seated in groove.
f 16.
Seat new lockirg washer (6) on flange of adapter l
f (4), or transition tube (5), depending upon nut j
configuration of arrestor being assembled.

Install adapter nut, or transition tube, in housing of support cylinder assembly (21).
Manually tighten nut, or tube, until bottomed against housing.
- 18. Torque adapter nut er tensition tube to 150 ft.
Ibs. (140 - 160 ft. Ibs.) as follows:
a.
Verify that locking washer (6) is seated flat between housing of support cylinder assembly (21) and flange of adapter nut (4), or transition tube (5).
b.
Install appropriate torque wrench adapter on adapter nut (4), or transition tube (5),
engaging setscrews of adapter with slots of nut or tube, c.
Insert torque wrench in socket of torque wrench adapter.
d.
Using torque wrench as a lever, rotate
, adapter nut (4), or transition tube (5),
clockwise until torque wrench clutch slips, indicating that proper torque has been applied. Document torque on Attachment 3.
- 20. Using mallet and punch, deform locking washer (6) a minimum bend radius of 60' in three places:
s.
One into housing slot of support cylinder assembly (21) b.
Two into slots of adapter nut (4), or transition tube (5).
21.
If new support cylinder assembly (21) was installed:
a.
Remove drive screws (22) and nameplate (23) from old support cylinder assembly, b.
Steure nameplate (23) to support cylinder assembly with new drive screws.
22.
Remove assembled arrestor from holding fixture.
23.
Slide position indicator tube (3) over telescoping tube of support cylinder assembly (21). Rotate tube until mounting holes in tube and end cap nut (20) are aligned.
POM 35.000.075 Revision 3 Page 44 24.
Coat threads of filister head screws (1) with Loctite retaining compound. Secure position indicator tube (3) to end cap nut (20) with new filister head screws (1) and new flat washers (2).
25.
Install transition tube (5), if applicable.
7.3.6 Document completion of Seciton 7.3 on Attachment 3.
7.4 Paddle Bearing Replacement 7.4.1 To remove a paddle bearing, drive the old bearing from its hole using a brass drive pin and hammer.
7.4.2 To install a new paddle bearing, proceed as follows:
1.
Prior to reinstallation of bearing:
Remove any metal burrs from hole in eyerod.
a.
b.
Check spherical bearing for burrs, dirt, grit or rust. Clean inside and outside of spherical bearing if required.
2.
Center the race of the spherical bearing in the hole. If reinstalling a split race type bearing, position the split on center line toward the threaded end of assembly, see Figure 1 of.
Check to see that the bearing moves freely inside the race.
3.
Place the assembly on the wood block so that the spherical ball of bearing is centered in the hole in the block, see Figure 2 of Enclosure 5.
4.
Use a center punch and ball peen hammer to stake the bearing in four places for small bearings, six places for PSA-35 and 100, on each side approximately 1/16" from the edge of the hole.
Depth of stake should be only enough to retain bearing race in place.
5.
Check to insure bearing totates freely in the race.
7.5 Post Maintenance Inspection, Testing and Restoration 7.5.1 Functionally test the snubber in accordance with Reference 3.1.3.
Document results on the appropriate Attachment.
P0M 35.000.075 Revision 3 Page 45 7.5.2 Ensure that all equipment labels and/or nameplates are reinstalled.
7.5.3 After completion of the work, the Protection Leader /
Work Leader shall sign the Maintenance Order and process the PN-21 in accordance with Reference 3.1.1.
