In these pics, you can see where I added a dedicated return line for my grapple

Grappel Update.... (The Thumb)

Well, after alot of work it's complete. A BIG THANKS to all that answered my questions & steve for posting the pics.:thumbsup::thumbsup::thumbsup: You can see in 1 of the pics. I found an inspection plate behind the power shift. I made a plate, welded in a nipple & made a return to tank .The hyd...

If the valve has 6 hoses, then the problem is there. What is happening is that you're feeding the third function valve using the Tank port of the loader valve. The solenoid valves don't usually have a built in relief valve but the loader valve does have one and it needs the Tank port connected straight to the tank so it can relieve the pressure.

By feeding the 3rd function valve using the Tank port of the Loader valve, you're basically deadheading the system every time you use the 3rd function. You're very lucky that you're just shearing keys because deadheading a pump usually results on cracked pumps, lines, valves, etc.

To properly feed the 3rd function, you need to use the Power Beyond (PB) port of the loader valve with the proper PB sleeve, while the Tank port will go back to the tank. You may need to check if the valve has PB ability though. It should be marked on the casting of the loader valve. It should have marked like: P, T and PB or C or N. P is pressure, T is tank and PB/C/N is power beyond.

One more question i did have some trouble with one of the quick couplers that goes to the grapple when I went to hook it up it seemed like it didn’t want to couple together but I finally got it to connect, is that Something that may be an issue?? Im pretty sure i plumed everything by directions i got but will definitely recheck? Thanks in advance!

No, that's normal. Don't leave the grapple open unless you prop it up because otherwise it's own weight will pressurize the oil in the line forcing the quickcoupler ball valve against the seat and make it hard to fasten the quickcoupler. Sunlight on black hose will do the same. Everyone with quick couplers knows that game.

There are quick coupler de-pressuring hand tools on the market that will hold onto the end of the coupler and push the ball in to allow a bit of oil to escape. Then it's easy....except now you have oil all over everything.

Old timers often have a clean red rag and a wood-headed mallet to "wrap it and slap it" to momentarily unseat the ball check valve. Put the oily rag somewhere in a baggie so it doesn't attract dirt.
Soundsl like you are getting there.

Question for ya. So can i put a T at the tank port of loader valve and run a line to my third function T port? Thanks for ur knowledge!!

Thanks for the pictures. It does confirm my theory that you were using the Tank port to feed the 3rd function valve.

The right way to get your system properly plumbed is to get the PB plug/sleeve for the loader valve. That sleeve with go on the N port of the loader valve, you'll need to remove the current plug that they fit from factory. You'll also need to know the brand of the valve so you can get the right one. It should have a nameplate or a brand name on the casting somewhere. Could quite tell from the pictures though.

Once you get that PB sleeve figured out, a line will come from that PB sleeve and will feed the 3rd function valve. The Tank line from the 3rd function will feed the rest of the system, the 3 pt in the back and maybe the removes if it has that.

Now back to the loader valve, you'll need to connect that Tank line straight to the transmission housing. On this part, I would ask our fellow members that are more familiar with these series of Yanmar tractors to chime in and hopefully suggest a good place to hook this Tank line to the transmission housing.

This way should make your system hooked the right way and trouble free.

For reference, this is what a PB sleeve looks like:

If you have any question, please ask. Sometimes my explanations don't come out very clearly.

I had a 2210D
They do not have any aux hydraulic system.
The typical loader installation ties the loader system into the hyd pipe going between the engine mount pump and the 3 pt, your #4 photo shows the tie in.
The pipe gets cut, flow goes to loader, back from loader to the cut pipe, and continues on to the 3 pt.
* The 3 pt (with its relief valve) is after the loader
The only relief valve is back at the 3 pt.
Any thing that stops the flow, including disconnecting those loader connectors will dead head

So the loader circuit must be such that it bypass's fluid back out when no spool is operated.

I think Hoyt (sp?) was selling a relief valve kit for that situation.

All true, but it is a lot easier to plumb, no deadhead danger, no sheared pump keys, no back pressure on the return line, and smoother controls by simply using a loader control valve that has a relief valve and a power beyond port.

the loader valve that came on my 3110 Koyker loader had relief valve.
His loader appears to be home made, so No idea what loader valve may have been used

I don't know if your 2210 is the same as my 2310 but if it is there is a power beyond port under the seat. It is in the cylinder head of the 3 point hitch cylinder. To use it there is a little fussing around that needs to be done but it is in the manual. In the manual it is stated that if the proper and easy procedure is not followed the hydraulic pump will deadhead and this can either break the key or break the pump. It does indeed sound as if your pump is being deadheaded. If your loader valve does not have the proper port for power beyond there may be hope if your 2210 is like the 2310.

Hey Eric sorry for the delay, my loader valve does not have PB. Do u have any pics of were u added PB from your 2310? I do not have a manual for mine, I will attach photos of mine if it helps. Any tips help etc is greatly appreciated!!
