I have finally amassed and fabricated parts to complete my PTO winch assembly. I am aware of the shear pin that hold things together and acts as a fuse so to speak. I was wondering what can work well as a shear pin w/o buying one. It looks as if a 16 penny nail will fit, and wire nails are very ductile. I don't want to use a roll pin as it may not shear well if it has to. What do you guys that have used your wench extensively use as a, we'll say a "replacement"?
Thanks

I used a properly fitting nail once, and it bent and was next to impossible to remove b/c it bent a bit too much before it broke. I'd try the real pins from Toyota... just my $.02

How about a piece of mild steel round stock in a close fitting size? If you use anything other than the original pin however you are changing the load at which it will shear and either are not pulling the max that you can or are overloading your winch.

Well it does make sense that if a substitute pin material is used the varibles just increase. It all revolves around the fact that I failed to notice my need for the pin(s) w/ my last SOR order.
I thought that there may be a tried and true substitute. I've worked too hard on this to chance it on the cost of a pin I guess.
Do these "shear" often when winching, as like, when ordering should I get a dozen?

Pete-

even the late model winches (1997 J75's) are rated at 1,800 kg in a single line. second the stock pin-order 2-3 for spares.

I am an Idiot!!!!

I tried bolts, round stock, and other stuff too. The guy I got the winch from butchered the hole bad and it wouldnt hold the facoty pin at all.

All of those things would just shear with the slightest resistance.

I ended up drilling it out and using a 1/4 roll pin. It has never broke or sheared but I recently poped a spankin new 5/16 line

Like I said, I am an idiot <IMG SRC="smilies/biggrin.gif" border="0">
