Can someone give me the (working tip end) dimensions of the Bendix/King contact extraction tool p/n 047-05099-001 that is used to remove contacts p/n 030-01107-00xx as used on KT 76 and KX 155.  Please – no guesses – I need a caliper on this one.  I will be working under extremely difficult conditions.  



Apparently, this tool is also known as Molex p/n HT-1884

Thank you for your help.

    How many terminals do you need to extract?

    The tool size is not critical . . . it needs

    to fit inside the width of the slot in the

    connector housing and be no thicker than the

    depth of the slot. It's a thin blade that

    is used to depress the retention tang

    on the pin.

    Unless you have bunch of terminals to pull,

    suggest you try a sewing needle inserted into

    the center of the slot. The tang is only about

    .4" inside and not hard to reach.

Bob, Thank you for your response.  Fortunately, I have only two terminals to extract.  

I was hoping to get measurements of the actual tool; especially the blade thickness, so the contact would release easily, yet I wouldn’t have to worry about permanently deforming the retainer clip.  Also, I don’t have a spare Bendix/King card edge connector body to give me the slot width, but I could probably guesstimate that.



My idea was to cut a sliver of shim stock.  Do YOU have a guess as to blade thickness of this tool?



Yes, I may have to resort to the sewing needle approach, but I don’t know if these old eyes will be able to keep the needle centered in the slot.  Besides, trying different sizes, I can ruin only so many of my wife’s sewing needles before there is hell to pay.



Thanks again,



Jerry King

   There is possibility of 'flattening' the

   clip even when the 'right tool' is used.

   I always tweak the clip to increase it's

   grip before re-inserting a used terminal

   back into the housing.

   I don't think I've ever actually measured one.

   The last two that I made were fabricated from

   flat spring stock cabbaged from a pocket tape

   measure. I used a cutoff wheel in a Dremel to

   sculpt the material.



   Many moons ago I published this offering

   I believe these numbers were suited to

   the various versions of this pin retention

   methodology . . . but that was some time ago.

   Get your own needles. In fact, I think

   sewing machine needles are about the right

   thickness and they offer a 'handle' of sorts

   on the machine end. Again, a little sculpting

   with a Dremel would tailor them to the task.

I find that one of my very small flat screwdrivers (watchmaker type) 

often works well on these types of pins.

OK, I am armed.  Wife gave me an assortment of different size sewing machine needles (much better to not stab yourself with) and I also raided my collection of jewelers screwdrivers.  Now, if I could only see the back of the connector to tell which wire is which…



Bob & Ken, thank you very much for the tips.
