    Ferro, Glad you were able to get stopped with out and major problems. I'm curious, do you still have the broken pin? Does it show any signs of being previously cracked?

    This reminds me I need to check over my pins before I loan out my towbar.

    I've heard the Unmanned Arial Vehicles (UAVs) are amazing.

    It would be burrs most likely, from repetitive use that weaken the pin.

    If used extensively, it is always a good idea to change them out, and throw the old ones away.

    Just be sure you buy original mil-spec pins that come with the towbars, or from a GL auctions.

    There are plenty of people out there with them. I would never use a grade 8 bolt, or anything else other than the original mil spec pins specifically tested at the highest standards for these things. You just got to do regular maintenence on pins and towbars, just like you do on your trucks, though it is not something we usually think about. Why? Cause they never go bad.

    This is an extreme rare exception.

    I think the lynch pin failed for some reason, and allowed the 1" pin to come out.

    The ring can come out of the head of the lynch pin, then there is nothing to hold the lynch pin in.

    I tend to agree. I just can't see a 1" pin breaking under normal conditions.

    I replaced the lynch pin with new ones not that long ago.
    If the new lynch pins were "foreign" manufactured, I have seen the rings come out of the head with one or two uses. The quality of "foreign lynch pins is very low(non spring steel rings).

    There's a good reason TSC or ACE can sell them, 10 for a dollar.
