The '84 manual says the maximum tow speed is specified in the '10 for the towing vehicle.I wonder what changed between 1972 and 1994.
Possibly the towbars? MWO's?
Why would they have ommited the speed limit in the later TM?

I can tow for pleasure , not for hirerDoes your insurance cover you to tow?
More importantly, have you gotten it patched up yet? How is that old girl doing?
that's what i read, too.The '84 manual says the maximum tow speed is specified in the '10 for the towing vehicle. ...
Yes, I posted the original .pdf file here back in Sept. I believe, for all to see and download. (If you mean the MRAP towbars. )AngusT, do you have towbar TM info for the new bars you sell?
TOW4, you do realize of course most destruct testing is done on new material, not well used material that has already been through a great deal of stress.Having done a lot of destructive testing on large bolts, pins, and other hardware I would say it's more likely that the saftly pin failed and allowed the 1 inch pin to come out.
The Towbar manual that was posted (4910_496_10_towbar) did not mention safety chains. What we have learned here is proper rigging and safety chain use prevented a mishap.
The OP has a lot of experience and it paid off. Thanks for posting.
I'm very familiar with failure analysis 3dAngus. The whole point of engineering is to make something that will just barely not fail.TOW4, you do realize of course most destruct testing is done on new material, not well used material that has already been through a great deal of stress.
You have to do a reverse engineering of a broken device to determine cause. i
I am thinking what we have here based on the OP's comments is this was a well used pin. So where every well used pin would suffer different levels of fatigue, I am not sure we can say conclusively the pin did not shear.
I do agree with you the simplest answer is usually the best.
Anyway, I've said enough on the matter. Just be careful out there guys.
Over and out.
I wish i had a towbar
