Parts for a 300U Davis 102E Loader

The 300U is finally running, and the next problem is the dump cylinders on the Davis 102E are missing. Well, I have the parts of one but the other is flat gone. Previous owner was going to get it fixed but some shop told him it was not repairable and just get a new set. The dump hoses have been bypassed and the lift works like a dream, so I'm hopeful...

A 102 manual I found online seems pretty close but the listed hydraulic hoses for the list cylinders are not like the (half rotted) ones I have. It seems the same in the drawings so maybe it is and the hoses I have are replacements that are longer than necessary?

Anyway, where is a good place to purchase replacement cylinders? The manual claims (which I can't find the reference now) 2 1/2" piston with 15 3/8 travel or some such. Pins are 3/4". Locally I can get bolt together 2 1/2" with 16" throw and 1" pins. I don't know if the extra length will make a lot of difference, nor do I know if the bolt together kind are ok for this purpose. Not even sure it will fit against the arm because of the increase in diameter.

I also would appreciate a good source for appropriate hoses? Seems like everyone around here sells hoses, so if a hose is a hose is a hose then I'm golden Sorry for what may seem like a simple question, but this is new to me. How do I judge the condition of a hose? Just replacement as they burst or is it worth buying a set? The hoses to the 3pt are all relatively new, but all but one to the loader you could convince me they are original (not that I can really tell, they just have been oversprayed with several colors of paint and have dry rot and a few flaps of loose skin).

Thanks for the help,

surpluscenter.com is a popular suggestion on this site for hydraulic cylinders. They have hundreds of sizes and styles, maybe thousands.

It's going to be tough finding exact fit cylinders but you need to come as close as you possibly can in order to get proper bucket action. To get a cylinder to fit without modifying the loader, you need to know what the closed length of the cylinder needs to be. This is measured with the bucket rolled all the way back, from center to center on the holes where the cylinder mounts.

And you're right, hoses are hoses. You just need to determine what kind of ends you need on both ends and the length, then go to a hydraulic shop and have them made up. There are choices for hose but you don't need the expensive high end hose. 2500PSI hose is plenty.

The cylinders you found local will work fine with bushings for the 1/4 inch difference in the pins. One thing to watch for is the diameter of the replacement cyl.,I have a tractor that the replacement cyl were so wide, the the PO beat the loader frame with a large hammer to get clearance for the cyl. Just be ready for the cost of those replacement hoses,the last 14x1/2 one I bought was $100.00.

Looks like I need a unicorn...

The original cylinders have a clevis base, and a crosstube rod end. I reassembled the parts I have and it is certainly not original. Looks like someone made this with a screw-on crosstube mount and threaded it on and then welded it on as well.

I see some modern cylinders that have threaded rods with clevis on both ends. What I can't find now is a screw-on crosstube mount. All the ones I see are welded on. I suppose I can chop up the clevis rod end and put a crosstube on it (?), but if someone knows of a screw-on crosstube mount for sale that would best?



The other issue is that these cylinders are dual ports, but I suppose some creative plumbing can resolve that?
