Hello All, I did find some more informa on from previous inspec on reports for Contract 06-C-0061. Please see the a ached cer fica on.

VR,

Navdeep Sharma

Good a ernoon all, Here are the answers to your ques ons:

1. The diameter callout should go from the groove on one side to the other. This groove/slot is where the O-ring (P/N: 988AS150-2, Size: AS568-010) will go. The O-ring has the following dimensions: Inner diameter: .234 min, .244 max; Width: .067 min, .073 max. This means that the O-ring can have an absolute max and min outer diameter of .39” and .368”, respec vely and an average outer diameter of .379”. This ensures that the O-ring has a ght fit and that it won’t move during assembly or during firing.

2. The .37” diameter dimension is for the inner sha of the plug and does not correlate to the inner grooves (where O-rings are placed). The diameter dimension that is assigned to the inner grooves is: .360" -.001/+.003.

3. The .37" -.00/+.01 diameter callout shown in zone B-3, should correlate to the 1.255/1.265" deep inner sha hole.

4. NSN should be the same as JM60 (1377-01-520-9738)

5. Navdeep would have to answer that ques on for you. He should be able to access the lot folders tab in VFS telling what the part was cer fied to (Type, method, sensi vity, etc.). I unfortunately don’t have that informa on in my database but he should be able to get that to you. Navdeep, please let Latrice and I know so that she can move forward and I can update the drawing to reduce confusion.

Hope this helps!

Ques ons for the following on the CKU-5 Machine Parts M1-0035

I am reviewing the engineering for the subject RFQ, and I have a few questions regarding the 512-174-0076 drawing:

In detail “B” of the drawing it shows two I.D. grooves at .360” -.000/+.003 dia. But the dimension line for this feature does not go all the way to the dia. of the groove. Should it? It is slightly above the dia. feature.

In zone B-5 of the drawing the I.D. groove is again dimensioned, but this time at .37” -.00/+.01 dia.

The drilled hole that is 1.255/1.265” deep has no dia. callout, and is thus unknown in dia.

Just a guess, but this is what I think these dimensions may be:

The .360” dia. shown in detail “B” should be drawing to the full dia. of the groove(s).

The .37” dia. shown in zone B-5 should go to the drilled hole that is 1.255/1.265” deep.

Please review and let me know your findings.

Could you provide me with a NSN number for the Wire, Lock 11735367 Rev H – Wire, Lock?

What type, method and sensi vity level of penetrant tes ng do you require? ( Plug, Breech ) Drawing Number: 5184315
