Possible Log Splitter Cylinder ?

[Whitespider]

High(er) pressure hydraulic cylinders use different seals and seal clearances... i.e., the cylinder parts are held to tighter tolerances.
If they ain't designed for high pressure, no matter what cylinder wall thickness is, you'll have internal leakage in short order.
Good luck, I hope they workout OK for y'all. Who knows?? They may be rated for 10,000 PSI just as easily as 500 PSI.
But really, without the specs it's a crap shoot... personally, I'd need to see specs before I dug in my pocket.

Where are these cylinders for sale I may consider purchasing a few?

Hello all this was his response to me on the cylinders when I asked the working pressure.

"The wheel loader is set to function at 2000 psi with relief pressure valves set at 2250 psi
We test the loader at 10,000 lbs. bucket capacity (2 ½ yd. bkt.)"

These are loader bucket cylinders and I bet a log splitter will be easy work for them I wanted to get 2-4 from the get go to have a spare or 2. I just have not hooked up with him because he is pretty far away.

Something does not add up, case wheel loaders operate at 3625psi. Going back 20+ years they've run over 3000psi. Makes you wonder if someone is doing a little CYA. The skid steers run at 3400psi so it isn't just confusing machines.

What gives you that idea?? So what if the loader bucket is "tested" at 10,000 lbs.??
There are two of those cylinders on the loader arm, meaning an individual cylinder is "tested" to 5000 lbs capacity... 5000 lbs = 2½ ton.
Are you building a 2 ton log splitter or a 20 ton (40,000 lbs) log splitter??
You need the specs for the cylinder... the specs for the machine it was mounted on mean zip.

you need a lot more math there, a loader cylinder doesn't lift the load vertical, you would have to know the angle of the cylinder, where the bucket is in relation to the cylinder, where the load center is of the 10,000 lb. (is it at the cutting edge, back, or middle of the bucket, and a few other things... it's nowhere as simple as you're putting it

 

[Whitespider]

I agree 100%...

 

[brenndatomu]

I agree 100%...

It finally happened!!!

Ok if I get this how would I go about pinning it. Can not find a clevis or bolt to what looks to be around 2 1/4" -2 3/8" ball park. Seem hard to find anything over a 1 1/2" diameter . Any ideas ?

4140 solid round stock... small quantities can be ordered through places like McMaster Carr, MSC, Grainger or other industrial supply companies

 

[brenndatomu]

Could probably get a short piece of cut-off round stock from a welding or machine shop for just a few bucks

Why weld that back on there after cutting the shaft shorter? Face it off. Chamfer it. Drill a hole through the shaft to accept a 1/2" bolt.

you know a cylinder needs 2 mounting pins...right?

Not on a log splitter. The design he proposes is a good one. The end of the rod goes into a socket on the push plate, could maybe even use the eye that was cut off, then you cross drill it for a bolt (or a 5/8" hitch pin works good too). The only force that bolt sees is the retract force and it doesn't take much to hold that.

Mr. HE

the rear mounting hole or anchor mount for the cylinder is the same diameter as on the rod end... i said it needed two because he only mentioned one, i also think drilling the rod is a good idea but the OP still needs a pin to anchor the cylinder...

 

[bowtieman427]

My goal would be to NOT weld on the cylinder or the cylinder rod. Personally I would never want to weld on the rod. I am NOT good enough to even try it. In the rear will be a pretty big pin from photo 2 1/4-2 3/8" diameter ball park. I will have to ask around and thanks for the info Nathon .
The rod pusher side I plan on just cutting the rod to length and figure out how to drill a hole in it to accept a common pin and build pusher from there. I really like the 5/8" hitch pin idea. They are common and reasonable. Once I get the cylinder I think I will start a new thread on a log splitter build ???

Found a place that has these 4 I - H beams not sure what ones would work with this cylinder. May want to design a Vert/Horizontal. 85-90% of time will use in Horizontal, but can see and after using the old one where Vertical would come in handy.
Here are the beams.
W6 x 25 @ 9'0" (6-3/8" Deep, 6" Wide, 7/16" Flanges, 5/16" Web)
W8 x 24 @ 9'-1" (8" Deep, 6.5" Wide, 13/32" Flanges, 1/4" Web)
W8 x 31 @ 9'-1" (8" Deep, 8" Wide, 7/16" Flanges, 9/32" Web)
W10 x 22 @ 9'-7" (10" Deep, 5-3/4" Wide, 3/8" Flanges, 1/4" Web)

All thanks again !!!!!!!

When ya get the cylinder and get a final dia. for the pin(s) if it some odd ball size I can turn it to size for you, shipping might be a bit pricy, but might be able to use the post office flat rate box deal.

The W8 x 31 would be perfect!!!

I know it has been asked a couple of time where these cylinders are located. Bowtieman, if you dont want to post it on the internet, you can send me a pm as I really would like to buy two of those cylinders.

 

[bowtieman427]

I think I sent you PM muddstopper not sure. I am newer to this forum and not sure if posting here is ok to do. I am also NOT the seller. I do NOT know the seller. I have NOT seen them yet nor want people to think I know what they are. I would post if ok or I experienced these first hand or used them before and knew if they were legit. After I have seen them with my own 2 eyes and know they are good I would have no issues posting where they are at. So please be patient. hopefully sometime this week I will see them and let you know more. Main concern is will they work and are they a viable solution for a log splitter. Looks like I need a big pin in the rear, cut the rod and drill a hole in the rod.
