OK, I'm needing some help.

As I've posted, the FEL on my newly purchased 1886 has single acting lift cylinders.

I need to replace them with double acting ones.

BUT, I need to know what to look/ask for when finding them.

Just how are hydraulic cylinders measured?

I'm assuming the the length of the stroke is one parameter, but what other measurements do I need?

Well there's tie rod ends which are more common, theres's welded Tube ends and welded clevis ends these can change the overall length of the cylinder.

Critical dimensions would be.
Stroke, bore, pin hole center to center when retracted. Port size and location. Pressure rating.

Could you post a picture of what you have, and of the ID plate on it, if there is one.
That might help.

I'll take a look/pics tomorrow and post them here.

Here's a side view of the tractor in question from a distance if that would help.

This might be close to what you need.But you will need to know the retracted and extended lenghts and the pin size

It shouldn't be too hard to find DA replacements for those. It will make a big improvement in the loader to have down pressure.
