Hyd cylinder parts

[handirifle]

On my splitter, the end plate, the one the piston goes through, has developed a leak. It started with a pin hole in the top section, that leaked occasionally, but now it seems to leak constantly when in use.

Can I get just the new end plate or do I have to get a whole new cylinder? I hope just the plate. I do not currently have numbers from the cylinder to reference. I think the main cyl is 5" with a 1.25" piston, but that's a guess.

It seems like all my leaks showed up at once. I also have a hose, and what looks like the shaft seal on my pump. Good grief, when it rains it pours. I am hoping to get all my splitting done before tearing it down for repairs. I am assuming the repairs will take me some time, and we have a couple long RV trips planned for the fall, and want my wood split before we travel. I have MOST of what NEEDS to be split, but there is more to do.

Is it a tie rod cyl? You are calling the rod a piston. The piston would be just under the size of the barrel.

What is a tie rod piston? I'm sure it's the rod diameter that is 1.25" Cannot see the piston, I assume that is inside the cylinder.

quote; What is a tie rod piston. I don't know! I said tie rod cyl. A tie rod cyl is that it has 4 long rods that hold the end caps on. The barrel and end caps have flat o rings to keep them from leaking and that might be what's wrong with yours.

OK sorry I totally blew that one. Yes it IS a tie rod cylinder. It has the long bolts. No, that is not what is leaking. There is a tiny pin hole at the top of the 1/2" thick end plate that the rod goes through. I can see fluid squirt up about 1/4" if I do not release the lever when the rod is all the way in the cylinder. At least is used to be that way. It's getting worse.

Well I thought I had a place booked mark that sold the end cap and other parts for them. I looked at all the info I have and can't find it. Take it to a hyd repair shop and maybe they can fill the hole by brazing it.

Here's where it's leaking

It's (I think) a 4" bore and 1.5" rod. Measured the rod, cylinder outside dim is 4.5".

For some reason my phone won't load your picture but depending where it is leaking I would look into maybe drilling the hole out to say 1/8 and down 3/16 or 1/4 inch then hit it with the mig welder. I say mig because I "THINK" (someone who knows correct me if I wrong) it would be faster and allow less heat into the end cap than brazing and possibly damage the seal.

That's exactly what I was wondering about doing. I HOPE that will fix it cause a new cylinder is pricey.

Brazing it would have to come apart, that's not hard at all. The end caps are cast iron. I was thinking with brazing that you might be able to fill the hole all the way up.
