How do you do this to a winch shaft?

[Rebar]

This is 1/2 of the winch shaft on a recently recovered M817. How did they do this?

The chain is also torn off of the winch cable.

Dude! What were you pulling on?

Also, anyone know where I can pick up one of these shafts cheap and how to reattach the chain to the end of my winch cable? I am also wondering whether there is non-obvious damage to some of the other winch components with this degree of injury.

This is great fun!

Thanks,

Rebar

Simple: put a steel bolt in place of the original shear pin...

You are lucky if it only twisted the DS, and not rip the PTO out of the transmission.

The rest of the parts look okay, but I am worried that other damage occurred before the drive shaft acted as a shear pin.

Hard to say until you replace the drive shaft and do an operational check. I think I would put the winch and PTO in the Neutral postion and turn by hand to check and make sure eveything spins nicely first. If you get any strange noises or it feels funny, time to disassemble and look further.

I have also seen roll pins used in place of the shear pin, big no-no! Have it re-tubed, they are not easy to find or cheap either.

Its not always the shear pin. My buddy borrowed my M817 , accidently put the winch in high range and drove the truck down the road. The winch clutch was disengaged. When he got to 2100 rpm in 3rd gear the shaft spit right out the bottom bashing the oil pan on its way .....real mess. That pto shaft is too long for those shaft speeds.

When I got the M54, the PTO was busted off the transmission. The shaft was still in place, but they managed to lose the yoke as well when they wired the shaft pointing down and drove off. When I took the shaft off the winch, there was a grade 8 bolt in place of the shear pin. Probably would be a good idea to put a touch of anti seize on the shaft when you put it back on the winch with the shear pin. Mine was rusted in place in addition to having the grade 8. It was a devil of a time getting that bugger off. The only fortunate thing is that the shaft does not seem to be tweeked.

Not totaly related to the tread, but where can I get shear pins for the deuce and 5 Ton winches.

doghead may have some 5 ton shear pins he could sell you.
Don't know for sure.

ordered mine from a parts supplier in Tennesee. Any good hydraulic shop or farm implement store should be able to fix you up.
