Today, I unspooled (and un-kinked) the cable on the rear winch of one of my M816's.

When I went to spool it back up, I was a little concerned when the winch drum did not turn!

Came to find that the shear pin was sheared, and I need a new one (the previous owner, Uncle Sugar, spooled the cable in too far, and bound up the cable and sheared the pin).

Currently making due w/ a 5/8" dia 4" long bolt, but I would like to have the correct thing.

Dia is 5/8", made of steel. Length is unknown (to me) as all I have is the center section. The pin is scored on each end. I can always take the pin out of the winch on my other wrecker, but asking here is a lot easier .

Anybody have an NSN or idea of where to find them? I did not see any info on it in the TM.

Thanks,

Andy

PS, greasing up 380' of 3/4" cable takes a LOT of grease!

I'll dig in the garage and see if I have one. What I got sounds like your description, just gotta find it.

yes that pin is a very large one.. big round head with notches cut into it.. i would hate to buy one but i would rather that than use the wrong pin. if i had more than one spare i would let you have it

From what I've read and some basicly calulations(which I think works). This is all assuming that the winch shear pin strength go up linearly with the weight the winch can handle.

I took the deuce winch max load and pressure the shear pin is suppose to shear., and multiplyed that by 4.5 (10k vs 45k) and a grade 2, 5/8in iron bolt is slightly weaker(about 5%) then what the normal shear pin. So you should be able to get away with one of these until the proper pin can be aquired.

That said, it really depends if the winch rating and shear pin strength scale linearly.
