I'm looking to replace them with 12" strokes since I'm already planning to modify a replacement bucket I got for $50. The slightly extra length would allow me to have the bucket curl up a little more at ground level yet still dump at an elevated position. I will be modifying the cylinder end bracket on the FEL to accommodate the longer length anyway.

Has anyone been able to source and/or recommend cylinders that would do the job? I tried Baileys and Surplus but can't seem to find the right fit in the 2" bore size. I've seen small loaders with 1.5" bore and was wondering if they may be ok for the bucket because I found some from Bailey's that will fit perfectly.

Hope you guys can help...

Try Northern Tool and Equipment, they have a pretty good selection of cylinders. Not sure if it's what you are looking for but they have several different ones with 2" bore and 12" stroke.

No Bulldog, quite limited. I'm at the point of just seeking verification that 1.5" bore cylinders will do fine. I've seen other slightly larger tractors have 1.5" cylinders so I just only wonder why the 2" on these.

You will lose almost half the cylinder force if you drop from 2 to 1.5". The number you care about here is the cross sectional area that your hydraulic pressure is acting upon.

Other tractors may have higher pressures and/or different loader geometry and thus not apples-apples.

Magkarl, Thank you! That makes sense and likely why the loader has 2" cylinders. I wonder if the limiting factor was the pump itself or the fact that it's the horsepower of the B7100?

Bulldog, that may just be the ticket! I'll have to call about the width of the cross tubes. While my old cylinders use 3/4", I suppose I can always use internal bushings to reduce the diameter. Hopefully it's workable!

Thanks guys!

True, hopefully I can do just that, if needed be. The question is the cylinder size, it just looks bigger on the website but then that could be the stock photo of a shorter cylinder. I'll let you know how it turns out!

A good machine shop can cut down rams and cylinders but the cost may be around the same for new.

They can't add length though (not reliably anyway) and so you can do some things to make them longer.

Buy longer rams. The stroke will be the same length but you'll adjust the action of the item being acted upon. Most of the time they'll just relocate the 'mount point' of the cylinder to do the same thing.

Buy much smaller rams and create a mechanical cam/fulcrum to adjust the mount point of the main rams. You connect the small ram in parallel with the larger one but use the small rams mechanical advantage on the fulcrum to actually deliver more power to the main ram. This is actually seen out of the factory on some heavier duty loaders and such.
