Fisher Angle Pistons Breaking

    I work at a machine shop and had a buddy ask me the other day if I could have my shop make some new ends for his broken angle pistons to weld on. He has six broken angle pistons that the ends of the rods where the pin passes through broken clean off. He has several plows ranging from straight 9' footers to the extreme V's and says it's not specific to any one plow. He's saying at $330.00 each time he replaces one he wants to at least try to fix a couple of them and see if they hold up. Is the end snapping sheer of the piston rod a common issue? Anyone ever try fixing one this way?

    Thanks

    Never had that happen to any fisher piston and I run a few on skidsteers with no preasure relief valves and never did that in 27yrs of plowing

    I've only been plowing about 8 years but here in upstate NY everyone runs fisher plows I've never had the opportunity to try anything else. I've never heard of or experienced the angle pistons breaking. I have seen them break through the the front of the plow before.

    28 years plowing mostly with fisher never busted a piston, or seen one busted with all my snowplow buddies. Just what is he doing to them?

    Thanks for the reply's and that's pretty much the answers I thought I would get. I couldn't understand it either but I did get a little more of the story last night. It sounds like it's more to do with the center pin failing on a V-plow and the angle pistons breaking when the blade folds over. Either way it's a maintenance issue and the angles piston are just collateral damage. We're going to weld four of them up with what's in the picture and send him on his way.
