Source of used hydraulic cylinders?
I'm doing a rebuild and some modifications to the front-end loader on my old Ford 4100 tractor. Part of the project includes getting rid of the original single mid-mounted tipping cylinder and replacing it with a pair of rams mounted on the arms. Does anyone know of anywhere I might buy a pair of used rams? I won't be able to confirm stroke length until I'm a little further along with the modifications but they will be something in the vicinity of 70mm bore by 450mm stroke.

New ones are reasonably priced on evilbay.

I guess 'reasonably priced' is a matter of perception, but looking at not much change from a grand for a pair of cylinders is in my book worth looking at used options. The tractor dealer who I spent way-too-much money with when restoring the tractor told me they'd look after me with the cylinders when I got around to doing the loader rebuild, but I figure it's worth seeing what used options are out there.

Whenever I have looked for cheap S/H hydraulic cylinders I have only needed one. Finding two identical cylinders would present a bit more of a challenge with S/H stuff.
Try scrap metal, Gumtree of eBay.

When describing cylinder specs, is the bore the same as the shaft diameter?

Hi Guys,
Not necessarily ! I've recently being playing with some that have a bore bigger than the shaft / ram.Best Regards:

You can buy a 2/12 bore cylinder with 2 ft stroke for around/under $300 each new on eBay the last time I looked.
By the time you buy used, put new seals in you will be up around that price.Using Tapatalk

Is there some reason you wish to change from a single ram to a twin ram set up. Working out ram sizes and geometry can get involved unless you are copying a known design.
I would not buy any ram second hand without being able to look inside them. I have seen some ugly stuff inside rams.
nadrojWhen describing cylinder specs, is the bore the same as the shaft diameter?
No. Bore is the inner diameter of the cylinder. Shaft (or rod ) dia can be close to it (pic on the right) or a lot smaller (pic on left) depending on application.

The geometry of the thing had been stuffed around with over the years anyway and it was going slightly over-centre, needed a lot of work- I spent a day cutting off forty years of farmer repairs. I'm putting a quick-attach setup on the front of it and the double-hinge tipping arrangement to get increased rotation (cos why not), sorely tempted to put a level-lift system on it too just for the heck of it. I've copied dimensions of a JD loader to get the linkages and pins set up, I'll confirm the stroke of the rams once I can mock it up. Fair comment about unknown internals on used rams. I'll give the dealer a chance to give me a price.

Sounds like you are on top of it.
The "double-hinge tipping arrangement to get increased rotation" sounds interesting. I would like to see a pic of that when your done.

Probably wasn't the most descriptive choice of words, I guess that's what pics are for...This pic from google shows what I'm replicating, pretty standard stuff but not back when my tractor was built. I'm sure there's a name for this arrangement of linkages and pivots but I don't know what the name is and haven't been able to find it anywhere.

Looks to be a fairly standard quick hitch arrangement.
I thought you might be going for a split bucket or 4 in 1 set up.

The quick hitch is not the part I was referring to, it's the set of linkages behind that (closer to the tractor) with the second pivot point. Would love to find the proper name for it.
I plan to buy or build a grapple rather than a four-in-one bucket, something like this https://www.google.com/search?q=wick...VY7peO3JZQZ0M:
I find it better to have an implement made for a specific job rather than try and make one do everything. Apart from moving dirt, I have a lot of trees and am always loading up the trailer with branches and throwing them off again to burn. Getting too old for it.

Sorry I have over complicated things. I use to call them bucket linkages, or the bits that joins the tilt ram to the bucket.
I went to a couple of my old manuals, JCB called them Shovel linkages, Komatsu called them Fulcrum arms. I am sure if I went through more I would find more names for them.

Yeah don't know what it's called, but it keeps the Rams out of the dirt.
Maybe a little mechanical advantage, but I think the main reason for that system on machines is to keep the Rams away from harm.Using Tapatalk
