What is leaking?

[future_vision]

I changed the o-rings on this connection to the hydraulic pump but it looks like fluid is still leaking out at the connection. What am I missing?

Pin hole or crack in the welded area of the pipe, or incorrect/pinched O ring?

Looks like the leak is higher up. What is the the yellow line? It looks dripping wet.

Good point. What was the original situation that you thought you needed to change the o-rings ? Maybe it was a false flag. Like TinHack suggests here !

Well. I would stand outside the tractor and move the joystick and see fluid spray out at the connection but maybe I miscalculated. I want about to stick my face in there and get sprayed. I'll need to check again. Maybe later today when I can get over there. Would be great if it was something simple.

Need to check

Yellow line is just the hydraulic cover when they are disconnected.

Are talking about a Hydraulic Quick Connect? Why is it wet? If the leak is indeed coming from the flanges, you probably used the wrong seal.

Get a piece of board 2-3 ft long and use the board to show oil spray. Use a board the length suggested to keep fingers(use gloves to) away from high preassure spray. Oil in the blood is a hospital job

No. I have some leaks with those too when the hydraulics get hot but this is about the connection in the image I posted.

Use a pressure washer or a can of brake cleaner to get the whole area as clean as possible. That will make it easier to find the leak. Also in my experience leaking orings and seals don’t spray oil. They just kind of seep out. A cracked line or pinhole in a hose will spray. And those can be very dangerous. Don’t use your hand to feel around for it. Good way to loose a finger or two.

Wrap some paper tape around the suspected joint. When you operate the valve the torn tape will make the spot that is leaking will be readily apparent.

If you see a spray, your leak is on a pressure line not a return line. Have your wife get down close when you activate and see where the leak is. Good luck.

If you use a piece of cardboard. Place it above the respective part to make sure it is from there are above.

I agree with Tinhack and acarr1. There is also a fluid leak higher up and doing a good pressure wash and letting it dry first will be the first step in locating any possible leaks. As all have pointed out, pressure leaks are dangerous, and unless you are bent on getting rid of your wife, use a piece of card board and not her face to locate the possible source. Placing the cardboard as close to the engine as possible will help lead to the exact location of the pressure leak. Curious, I looked up the Model No. shown in the photo, thinking that was the hydraulic pump, but it appears to be the engine model nbr plate for your Kioti tractor.

Best guess is the bent hydraulic pipe has a stress crack in it either under the fitting or or at the swedged end. Not uncommon after many cycles. I would replace the hydraulic formed line

Not so sure about pressure washing, I always thought the “clean spot” was the best tell when identifying hydraulic leaks.

Very likely the Kioti uses metric O-rings, which look similar to SAE dash number O-rings, but are not a match. Did you get the O-ring from the dealer, or just put in the closest match you could find? Also, hydraulic O-rings for flange connections must be 90 durometer. Most O-rings you get from an auto parts store are 70 durometer, which WILL leak.

Is the original picture shot looking down or sideways?
