Cylinder rod pitting - How bad is this?

[PILOON]

Piloon - I think it is more to protect the hydraulics than the plow. Impact inward on an extended piston will create huge hydraulic back pressure in the lines and could blow something. Impact on the retracted cyl would cause essentially zero hydraulic pressure buildup as it hits the solid metal stops.

I'll agree with your statement in principal but still in the scenario I described even the hydraulics are protected only on the extended edge.
OK, I'll bend a bit and agree that if plowing straight ahead then both corners are protected like doing a parking lot with big 'ears' to gather lots of snow.

I think they are not worth saving. I tried rotating the rod using a 15-18" prybar in each bolt hole, and basically they wouldn't budge. Bummer since they don't seem real bad otherwise.

When you are finally able to hook up your hydraulics you will only then know if the cylinders are good. And, yes, they can be stiff but quickly loosen with use.

Not sure if I want to wait until then to find out I need new ones, especially if I have to put more time into cleaning them up and getting them ready. If they were double acting, I could temporarily plug them in and run them back and forth a bit to see, but with them being single acting, all I could do is one push forward, one time. Not very helpful. I could maybe try remounting them to the frame. Dunno if it is worth it or not. I don't have much time to get in depth messing with it right now either.

Yes, the extended edge is the only edge protected, but you have the "protection" backwards. The crossover is NOT designed to protect the plow. It is designed to protect the hydraulics. So the retracted edge doesnt have hydraulics holding it. (It is against the mechanical stop). So no the crossover dont effect that edge, because there are no hydraulics to protect.

The trip springs are what protect the blade itself. Assuming you catch something low on the blade.

I dont knwo if I gave you the link but baileynet.com is the Place I was talking about that has aftermarket cylinders. The 1-1/2 x 10 cylinders are $53ea. You will want to measure your extended and retracted (if possible now) because they do list a couple different 1.5x10 cylinders

You can try some compressed air. Hook to the cylinder, but use a regulator that way you can slowly increase the psi instead of blasting all at once. ...........

This is never a good idea. If the ram breaks loose it can hit the end of the cylinder hard enough to severely damage it or even cause it to be broken and as hard as it might be to believe, people have been killed doing this very same procedure.

Lots of things we do in every day life can be classified as dangerous.

That is why I said to use a regulator and slowly creap it up. I know it "can" still break loose, but not as likely as just hitting it full blast with 100psi.

And if it were ME doing it, I'd use the regulator on my compressor, and the cylinder at the end of my 50' hose:thumbsup: and possibly even outside if I thought it was going to go with a bang.

If you have a bar clamp, or a big "C" clamp, or a press, or anything to push on the rod with, just push the rod back in (with the hydraulic port open of course).

x2 .......very VERY dangerous.......

Good to see the safety police showed up:thumbsup:

You have no idea at what pressure it will finally break loose. Maybe it takes 5 psi...maybe it takes 90 psi. Using a regulator does nothing to change that. Once it breaks free, it is going to slam into the end of the cylinder, likely at high speed. That can and has resulted in a varying degree of damage to the cylinder ranging from a minuscule amount to a catastrophic amount. As I said, there have been instances where people died using air to move the rod.

From reading your reply, it is quite evident you have never done this yourself. "if it were ME doing it". "if I thought it was going to go with a bang." "If I" and not "when I". Giving people bad/poor advice is one thing when it would be harmless to follow it but when it has the potential to cause damage and injury or even death, a person has to know what they are talking about before they give it.

You post "Lots of things we do in every day life can be classified as dangerous." and "Good to see the safety police showed up." as if they somehow have a bearing on it. Doing something dangerous because you are either too stupid or too lazy to do it safely doesn't make it right to advocate to the next person to do it also.
