67 Loader Cylinders

[SwingOak]

Anyone replace the cylinders on their 67 loader? If so, what did you use?

Just got done putting a new bucket on my dad's 750 with the 67 loader, checked the bypass pressure and it's at 2300 psi, so the lack of lift is probably the cylinders bypassing. I'd pull them off and rebuild them, but by the time I'm done getting the seal kits and all, might be 1:1 cost wise just to replace them.

Look up how to test the cylinders. You can test them for bypass and see if thats the issue before you spend any money.

As far as buying vs rebuilding.....most loader cylinders are made to fit. They arent an off the shelf common part like a logsplitter cylinder would be. And they arent easy to duplicate or modify from an existing cylinder.

Rebuilding them will probably only cost $25-$30 worth of seals each and they arent hard to do if you have average mechanical ability

How do you check the cylinder's bypass pressure? I've never heard of that.

I assume he is talking about relief pressure of the hydraulics

I can see that the relief valve might actually be what he is testing...but maybe not since he says he is thinking about using that 2300 psi "bypass" pressure as a reason to rebuild his cylinders.
There may be a way to test for bypass inside a cylinder. I've never done it, but that doesn't mean much....& always ready to learn some more hydraulics.

My thought is there looks to be room for some more discussion before rebuilding anything.

Yes, I meant relief valve pressure - it opens at 2300 psi. I've rebuilt my fair share of hydraulic cylinders, pumps, etc. and have the tools and skills, what I don't have is time. Just wondering if anyone has found any drop-in replacements.

I were to take them to a hydraulic shop to have them rebuilt, every shop in my area charges at least $130/hr and will take a couple weeks to get done, so by the time I get them rebuilt, I could replace them right away for about the same money.
