Not sure if this counts as "advanced tech" so feel free to move. Slowly collecting parts for the dump trailer's hydraulic system... want to make sure I've got this right. It's exactly the same as a woodsplitter. I've tried finding schematics on the web, but nothing. Here's what I've got; Does the valve bypass the cylinder in the neutral position? If I wanted to install a couple pressure gages... would before and after the cylinder be good spots?... or before and after the valve? High, and low press? What about a temp gage? Where should that be to monitor the system? Anything else I'm missing?

Glen not sure on your valve. But for this applacation you need an open center valve, one that dumps back to tank. When the pump is on, the fluid will go into the valve and out back into the res. If you push forward or back on the lever it will move the body up and down. For pressure guages. if you want pump pressure put the guage right after the powerpac. If you put it on the cylinder, put it on the top, that will measure your load. A temp guage should not be needed. A wood splitter runs alot longer than you will be dumping. One more thing you should mount your cylinder under your box on on an angle, about 20 to 25 deg. If you keep your cylinder where it is, you will need a cylinder the lenth of your body to dump at a 45 deg angle.

You only need 1 hose to the bottom (furthest away from the piston) of the cylinder. Gravity takes the power down, you don't need (or want really) power down. Its more the unit than a power pack. stores.daltonhydraulic.com/-strse-Hydraulic-Power-Units--dsh--DC/Categories.bokThe power up gravity down are the cheapest. You should look at the air over hydraulic as you have air on the jeep.... that would definitely keep it cheap.

Well here's part two that explains why I want the cylinder on the outside, and a gas powered pump; The dump could use a 2" bore cylinder, but seeing as how I'll be using it to split wood, I'm going to go with 3". It should produce 20Klbs of force. From the pivot point to the front of the trailer is 59". If I can find a 3"X60" cylinder I'll get it, but if not I'll settle for 48". The valve will be a splitter valve, so that it has an auto detent on retraction... closing the dump, or retracting the splitter.

Ditch the gauges and the temp . Its a simple system really . your making way more complicated then needed

NO offence, but gearing up things like this usually end up with neither working well in either situation. You dont want a wood splitter cylinder travelling 48" everystroke unless your splitting woood 40" long, youll waste more time waiting for the cylinder to get to the junk of wood than you would splitting. I realize your trying to keep it cheap, and theres noone cheaper than me, but my advice is do both independently and do it right or yull have something that either works poorly, or costs you more in the long run trying to make it work. As for splitting hardwood, how much do you plan on doing? 5 chord a year? novascotia.kijiji.ca/c-buy-and-sell-business-industrial-Wood-Splitter-Rental-W0QQAdIdZ248008548Heavy duty wood splitter for rent in the Fall River area . $85.00 for 2 days , and $20.00 per day for additional days .

Alright, let's try to stay on track here. Are the components and plumbing in the first pic in the correct order, and am I missing any parts? Scott; I like monitoring pressure systems. It's kinda what I do. Mo; The "I" beam's going to be about 2' long, not using the full stroke of the cylinder. I don't burn wood to heat my house, I'm only wanting to gear up a splitter because essentially I'll have everything needed other then the beam... I have lots of dead wood around my place and instead of just wasting it, I like to junk it up and give it to neighbors. I'll also be gearing up a little outdoor firepit.

Glen I forgot you dont burn wood. I do remember ya boil water for a living. If you want wood split for your outdoor fireplace, you can burrow my log splitting device, AN AXE.... I dont need to split the wood for my fireplace on the beach. I say just build a trailer that dumps and leave it there. The logsplitter would sit around and would be one more thing you will back into, or mow around.

LOL, it's a two foot piece of I beam!!! I'll throw it in the shed. Most of it's soft wood... shit loads of knots. There ain't no splitting it with an axe. Prefer soft wood for outdoor firepit anyway.

2 ft of I beam is not enough for a wood spliter . your prob gonna need at least 6 ft .You will need to weld on the "knife" at one end , and be able to mount the end of the cylinder on the other , with a flat push spot on the middle , at the other end of the cyl and that will have to have a guide , thats able to slide up the top of the I BTW Ill take as much of the fire wood as you want to give away ! I can bring a dump truck , I burn wood

Sorry Scott, in-laws are getting the hardwood, two neighbors don't mind burning softwood, and I've got a friend with an outdoor fire pit that I'll be supplying as well as mine.

Ok, that's funny ... but seriously are the filter/tank/pump/valve/cylinder in the right order? Missing anything?

Yep there in the correct order. The only thing missing is your engine that runs the pump. The oil looks a bit low to.
