Second rear remote crossover

[liberty2701]

I added a second rear remote on my Kioti Dk50se to operate a root grapple. I am wondering if somehow when I operate the backhoe it is crossing over into the other rear remote which I use to operate a root grapple. The reason I say this is because the fittings up front will drip(from the ball) when the system is under pressure. I thought maybe the fittings were bad so I replaced them with no change. Is is possible I am dropping some pressure through a crossover? I think my backhoe pwer feels less since adding this remote.

not sure what you mean by "ball"? and cross over? diagram or better description of how hyd fluid is flowing through your setup.

a generic statement = a lot depends on the valve you added. smaller size internals / simply adding more hoses / fittings = more pressure loss through out the system. as a result less power while operating (stuff is moving) the pressure will build up but it may take some time. how long not a clue.

The ball is in the fitting that seals it when you disconnect the hoses.
Maybe it is called a plunger,not sure. It drips from there not the threads. The second rear remote is nothing more than another valve stacked onto the first rear remote valve adding two more ports to the rear actuated by another lever. You can see the setup in the pictures. The additional rear remote was a kit from Kioti. Crossover meaning that fluid is leaking between the valves since they are stacked causing my drip at the front hoses including a drop in hydraulic pressure ( reduced backhoe power).

Did you check and reset the relief pressure on the new valve?.

Most relief are set the same as the tractor relief setting.

The relief pressure is not set on this valve. Is is just a dble acting valve. Center off,left on ,right on. Like a dble throw light switch.

It sounds like what you're describing is a closed center valve...is the tractor system (valves) also closed center?

 

[liberty2701]

Yes. The first rear remote vakve has a dble acting lever(center closed). The second rear remote is stacked on the first valve( i guess this is parallel). The second valve that i installed drips at the quick connects up front. It is as if it is getting fed pressure even though it is not being used. I figured the quick connects should hold back any fluid. Maybe they are not designed to get pressure when disconnected? Maybe something is in the valve keeping it from getting a good seal feeding some pressure up front? I ordered a pressure guage to see if pressure is building when the lever is in center/off.

All valves have a little leakage. That said the quick connects should not leak. One of my Chinese quick connects (the male one) up front leaked. I Replaced it with a Parker brand and it don't leak any more. It would drip all the time about one drip per minute without being hooked up or in use. Bottom line is your quick connects leak and so does the replacement one. Now there might be a tiny oily amount now accumulate over time, and I would consider that normal. But a drip a minute is not normal. And replacement of the quick connect solved the problem.

Why only one hose for the left remote?

It drains to the hydraulic fill port. Supposed to keep the oil cooler.
