Hydraulic Cylinder Question

#11 is the breather

These plugs are solid, with no vent. Maybe I can find a plug that vents to keep this working right awhile longer.

Maybe the place that builds my hydraulic hoses will have one.

I’d loosen one of those plugs and see if fluid has built up behind ram.

Probably will do that when I hook up next time. I have it unhooked from my tractor right now because that tractor is in hay moving mode.

Yeah, it looks like it to me as well, and the other batwing shredder I have looks like that.

But near as I can tell, by looking at this cylinder, both plugs are solid. I've put some Kroil on them to help me remove them when I get hooked up next, but it has the appearance of two solid plugs to me. A vent plug usually extends out some, doesn't it?

It's magical. Must be for sure.

Must be. The bottom of the cylinder has two outlets. I've posted pics of both.

Perhaps you can point out the vent plug to me?

Neither of them plugs in the pictures look like vents. Single acting cylinders can work with one port plugged they just compress the air on the blind side. This could be a cushion effect when winging up. Not normal but can be done.

Must have a one way Chevron type piston seal to accomplish this. Just thinking that crd and oil bypassing to the base possibly causing the problem

I believe that's what that is.

I had another Woods batwing cutter that was really a POS, compared to the one in question.

The wings were sticking and not coming down, so I removed that one solid plug, and converted the batwing cylinders into two way cylinders. It worked fine until I sold it for half of what I gave for it.

Solid??? How does the cylinder vent then?

It doesn’t necessarily have to vent. It could just compress the air inside. The problem starts when the seals leak a little bit and fill the sealed cavity with oil which is probably the problem with this cylinder.

I'm thinking that as well. Probably going to remove the solid plug and put a vent plug in. After 10 years of pretty substantial use, the seals have to be letting some fluid by.
Perhaps if I can vent the bottom successfully, then I can put off having to redo the entire cylinders for awhile.

Top of the cylinder is pretty clean, and it's not been pushing any oil out.
