How to measure hydraulic cylinders

Looking at my measurements here. What size are these? I'm guessing 20 inch and 1-1/4 ?

Thanks! After calling a couple highly recommended repair shops and being told starting price on rebuild is $160 each,if not bent bad or rust pitted, I started hunting new ones. Maybe way cheaper......
 
Stroke length (amount of travel measured from fully retracted, to fully extended)
Overall length pin hole to pin hole (measured when retracted)
Diameter (inside diameter of the cylinder, not the rod)
Mounting hole diameter and style (Clevis one end/both ends, single tab W/hole)
and finally working pressure. So the rod diameter will follow the above specifications and be sufficient for use. Jim
 
Amazon and ebay are also viable sources--got my last cylinder off Amazon and have been pleased. Quick look on Amazon says $127 and free shipping, though you'll want to check to make sure all the specs match up and other places may be cheaper. Rebuilding them yourself is also an option--if the seals are common ones and nothing else is bad, you can often get away under $50 for smallish cylinders with low pressures, which these would be.

As long as they are not welded ends, you can rebuild them.

Seals are available at online seal suppliers.

You kinda need to open one up to get an accurate ID measurement.

Some calipers will be a handy tool to add to your collection. You need to be more accurate than eye-balling a tape measure.

If you replace the cylinders, be very meticulous in your measuring, study everything closely. Getting it wrong will be very expensive. Pay particular attention to the pivot travel. The cylinder MUST NOT bind in any way, that may be why they are bent. Check the pivot clearances closely from full retract to full extend.
 
Look at Bailey Hydraulics too. They are out of Knoxville. I've found some really good deals there from time to time. Would be a nice day or overnight trip for you too.

Remember it will be almost impossiblet fine correct mounts, every thing is propritary to a specific maker. Might have to get the old ends put on new cylinder. But some loaders the top piviot end is the pin thru the shaft of the lift cylinder. Now a cylinger for your haybine is a different story, those are a standard size and type.
 
Kevin, check Titan Industries, good prices and free delivery. I replaced both lift cylinders on my Fasco loader for just over $200.

Those appear to be single action cylinders, not double acting which is needed on a loader bucket.

My reply about the cylinder type was to OldFarmTractor's post. [/quote]
 
I agree . My old farmhand loader does have bucket cylinders with just clevis pin ends on both ends but most of the loaders you won’t get that lucky
