Loader Hydrolic Value

[J_J]

I have the 284 and it is an open center system.
Those 2 sites are incorrect.
I sent an Email to the first and will call the second tomorrow to ask them to correct their sites.

Thanks, I am glad you corrected that. Those were the only sites that listed the GPM, and the type system.


greg_g,

I do fully understand the differences of open center, and closed center hydraulic system.

Any idea how the valve cracked. Were you working on anything, or switching things around. Valves usually crack because the fluid has no place to go, and if the pump is strong enough, then something downstream will let break.

When did you find the crack, before you installed the loader, or afterwards.

My 284 has a open center system for sure. I have modified it highly adding rear remotes, a hook up for my log splitter, ect. I am 100% sure its open center. I also changed my loader valve.

Since you have 7 hoses you will need a Power Beyond kit. I would just order the adapters. They will cost you $10 and may save tons of frustration. You could not pay for the gas to drive 30 miles to get some if you did need them.

As for the valve cracking my guess is it had or got water in it and froze. This is strange since it was not even connected to your tractor when it failed.

If the loader were up, then disconnected via the quick-connects, and then dropped, it MIGHT create enough pressure in the valve to crack it. Sounds like the dealer screwed up to me.

Why not call Spirit Implements and ask? They have a toll free number and boast about good customer service - http://www.spiritmfg.com/

For what it's worth, on my Jinma 354LE with the Chinese ZL-30 loader I used that same Brand valve to replace my valve. I did not need power beyond. I did not need adapters as I had new hoses made. It works much better than the original.

I see in post #6 Brad has a link to Spirit install instructions, page 4 of that link has pictures and mentions power beyond, so you'll probably need the sleeve, but can't say for sure. As for GPM, the valve is fine, all you'll need to worry about is whether you need power beyond (get the sleeve, it's cheap enough, and you can install it or not depending on the requirement), mechanical mounting considerations, and connections. Spirit should be able to advise you on all this. My Brand mounted right up to my ZL-30, but note I needed new hoses (or adapters) because my loader was Chinese.

I say again, call Spirit and get their input. I agree with Chris (or Rich) in the posts below the dealer screwed up and ker-blooie!

I dont think you are getting the full story. Now that we have it here is what I think happened.

The dealer did not know what he was doing. More than likely he was going to drop the loader so he pulled the tractor to where he was going to drop it. He DID NOT shut off the tractor. He then went to unhooking the hoses to the input, output, and power beyond. My guess is he unhooked either the power beyond or output first and it dead headed the pump. There was no where for the hydraulic pressure to go so the weakest component failed. Usually this is the pump or the pump seal.

Keep a eye on your pump and hydraulic level. If the level starts going down check you engine oil level. If the seal between the pump and the engine is blown it will happen.

I would bet my lunch money the dealer screwed up. Its weird that the valve failed before the seal I mentioned first but anything is possible.

Yeah, a cast iron valve body busting before an aluminum pump body blows would make me wonder. That's why I'm guessing the buy collapsed the loader cylinders into a closed set of hydraulic lines on the loader itself and blew the valve body.

I maintain that the dealer screwed the pooch and it was NOT a defective valve body - a bad valve would have blown long ago under use of the loader. That's why they have pressure relief bypass valves built into them, isn't it? But with the hoses connected together there would be nowhere for the pressure to relieve itself to, if you see where I'm going wit this.

Disclaimer: I'm a complete tyro when it comes to hydraulics so I could be way out in left field on this one.

Here's a link to the Brand drawing, maybe it will mount right up, maybe you drill a couple new holes.

What is the Spririt response? Do they not provide support for their loaders?

I called Spirit in Wisconsin on Friday. Apparently there is only one guy that deals with the loaders. I left him two messages on his voice mail and I left a third message with a real person. I have not received a call back from them. I will see if I get a call back on Monday. I put it out

I could not figure out how the valve cracked if the hydraulics were disconnected.

 

[Smalljobs]

Is there any chance that water could have become trapped inside the valve and then froze?

Somethings not right here for sure,the loader sitting alone could not build up enough pressure to "EXPLODE" the side of the valve out,I think it was still connected to the tractor also.

I would contact Ronald at Ranchhand Supply,he can build a kit for you that has everything you will need including a New Valve ,Brackets,hoses,fittings,ect.

Ronald will only build complete systems, so if you are wanting to buy the valve,you may not want to call him,I've know him long enough that,he can and will provide the whole system turnkey,but he will not be interested in doing just parts/pieces of this job .Everyone that I have sent to him have been very happy.

And he answers his phone ,give him a call 757-650-9124

No chance of water got in and froze. It has worked perfectly for 6 years. The temperature is in the 80's to 90's.

I think the equipment dealer screwed up. He works on alot on heavy equipment and I don't think the mechanic knew much about hydraulics on this type of tractor.

What should I tell or ask the dealer about this? I feel he should replace the valve but I know he will probably tell me it was defectice.

Thanks,

Don

The forces involved must have been incredible.

I have heard of instances where the quick connects, when disconnected at low temperatures and then allowed to heat in the sun become unworkable due to the pressure induced by the sun's heat.

Hydraulics are hydraulics regardless of the machine, Cat, Case, Euclid, Jinma...

Tell him it worked for six years prior to going into his shop and now it's broken. Ask him to explain the science behind his diagnosis of "defective". Tell him you are on his side and that you want a diagnosis that will stand up in court
