I have the tool and a m22520/1-02 head.

Just looking for the proper method of inserting the pin to be crimped as well as what a good test for the quality of the crimp should be.

I do not have a g-125 gage to calibrate with. Also, do not have more than a couple pins to practice with.

Thank you,

Keith McKinley

You should have a positioner to hold and properly position (gee...) the pin within the crimping pins. Which contact positioner you need is based on what socket/pin contacts you are using. To free-hand position a contact within the crimp head, well, for a reliable crimp I would think it not a good practice.

If you're just worried about the depth of the crimp, you can purchase some gage pins from McMaster Carr for a few bucks each. Don't offhand recall the go/no-go diameters, but I can check them tomorrow and post.

If you visit the Daniels/DMC tools site, there is extensive reference material to chose the correct tooling...

Thanks Ron,

I looked at the small pins that do the crimping and tried a test. I now see that the pin is actually inserted almost all the way into the positioner for the correct crimp. It also seems to "snap" into place.

I think my crimp was just fine as a healthy pull on the connection did not break it.

I probably should invest in the go no go tool and I do have the number for that. Saw one on ebay for 25 bucks

Thanks again

Keith

The G-125, aka, M22520/3-1 can be used to test crimp depth for both the small AFM-8 M22520/2-01 and large AF-8 M22520/1-01 crimpers. The NO-GO diameter is 0.0440 dia and the GO is 0.0390 dia.
Use SEL 4 for the /1-01 and SEL 8 for the /2-01 tools.

Plug gauges can be purchased from McMaster-Carr at this page
http://www.mcmaster.com/#plug-gauges/=5cx5qj
using these part numbers
23055A039
23065A044
for $3.06 each.

The G-125 tool is little more than a dual ended collet holder for these plug gauges with the above instructions...

  After the crimp is completed, give it a good pull test Don’t try to destroy it, but give a good firm pull.

  Do NOT archive

Some time ago on the aeroelectric list I posted and I believe Bob archived some NASA how-to documents on various wiring practices, among them harness fabrication and wire terminations. Included were accepted procedures to insure reliable crimps.
