Adding hydraulics to dump trailer
I'm buying a 1-ton trailer that is "dump ready". I need to add a cylinder with 24" stroke and hook it into the tractor. The dump cylinder can probably be connected in place of the hydraulic top cylinder. A few questions please.
1. Will any 24" stroke cylinder work? Any special features to look for?
2. Should I go to a hydraulics shop to get custom hydraulic hoses made? Or is there a safe and reliable way to DIY the hoses?
3. Are the hydraulic quick disconnects pretty much interchangeable?

There are different ends to the cylinder available but the most common are the ones used in the ag industry so they would be the most economical to buy. Depending on location, might dictate the amount of strength needed to lift the box to dump when full. I'd probably say a four inch should be be fine. I'd also use 1/2 inch hoses to transfer the fluid as quickly as possible to have a good dump speed. Hoses carry a lot of pressure and I wouldn't try to put the ends on with other then the proper machine.

Hydraulic hoses can be purchased at most auto part stores, ends-to-fit. They are also avaliable on line at very good prices with NPT Fittings. You would need the fitting adapters for your Quick connects amd cylinder. The replacable hose ends are OK for emergency repairs, but not for long term use.
We add hydraulic dump to 2-ton wagons and always use 4" bore tie-rod cyliners with clevis ends. The cylinders are available about anywhere hydraulics are sold since that is also the most popular log splitter cyclinder. I would bet your wagon is set up for clevis end cyliners.
You can get everything you need at SurplusCenter. We order a lot of parts from them and they have always been great to work with.

As far as the hoses go, northerntool.com has a pretty good selection of hoses for a decent price. I made the mistake of going to my local hydraulics shop for some hoses once, and they cost me about 5x what the same hoses went for at northerntool.
All hydraulic QD fittings are not the same. The ones at northern tool are not the same as the Parker ones on my 4110 power beyond kit. If you go to Mcmaster.com and do a search for: 'hydraulic quick' - click on the first item: 'about quick-disconnect hose couplings'. Near the bottom they show the different styles of fittings. My fittings were either an ISO series A or B, I don't remember which off hand.

According to their web page, the manufacturer of the dump trailer has some sort of hydraulic dump kit.... presumably manual.
I would start there.
Here is the web site.

KW: Another thing to take into consideration is pump pressure and volume at the tractor remotes. And the inside diameter of the hydraulic lines; smaller (cheaper) lines will take longer for it to operate. And the type of lift geometry makes a big differece on how much it dump (maybe not so much in a one-ton lift but the larger ones). A hay wagon style (and there are others) has much more lifting ability from a dead, fully-down position compared to a direct-lift hydraulic cylinder which tends to need help to lift. These are generally mounted low, down in the trailer at an angle. A telescoping, front mounted cylinder seems to offer the best lifting ability.

Mark, you sure are a master of digging up online information. The company lists a hydraulic kit for the DT-2000 but not the DT2000-TM (which is the one I'm buying). I sent them an inquiry and will hold off buying the hydraulics until they reply. Most of the ATV dump trailers use battery operated hydraulics so that's probably what it is but their reply should clear things up.
EW, I'm hoping to not have to do much fabrication. The trailer is supposed to be dump-ready so the lift geometry is already established. Hydraulics wise I'll use the same big hoses that operate my top-and-tilt cylinders so that should be OK. Not sure of the I.D. of those but the O.D. is a good inch or more.
Thanks for the good info everyone.

Actually I sleuthed the Northern Tool paper catalog. There was a tiny logo on the page that could only be discerned with a magnifying glass.
The other thought I would like you to tuck away is the fact that wood decking is not very slippery.
You may eventually need to line or shingle the bed surface with sheet metal to get it to dump smoothly, especially after the wood ages and warps a bit.

On the TM model Northern told me that any 24" stroke cylinder would work but didn't mention any sort of kit. A Millside response should clear that up. Cylinders seem pretty standard so this will probably be one of those projects where most time spent will be in the chasing down of the right parts.
