Just got a woods loader installed on my b2710. It has a husco valve with just two hoses to connect to tractor. The valve on the loader has a pressure relief I believe. How do I connect the two hoses to the tractor.
Hydraulic connection help B2710/Woods 1006 loader
- Thread starter Chistech
- Start date
The Owners Manual is a vsluable resource.
To connect the loader you need the adapter for the mid-outlet block on the tractor.
The loader valve should have both power beyond and tank outlets. If it doesnt you connect tank to power beyond return on the outlet adapter block (C). That puts you in uncharted territory with potential for damage to hydraulic components on the loader and tractor.

Just to provide you a bit more information about what that block is and does, see this thread for a similar application on a different tractor, you only need to read through post #1 to get the application information.
The dealer may be able to sell you one or you may have to get one machined. If you need to make one then you will need to use the existing cover for dimensions. You will simply drill two tapped holes through the new cover to attach the hoses to. I suggest using any type of sealing port EXCEPT NPT. See SAE ORB as an example. Then a fitting adapter to JIC hose ends makes life much easier!

What parts diagram can you locate that block in? I guess it is in some implement (FEL) parts list. But I have not ever bothered to look under the tractor parts list so am curious where they appear.

Navigating Kubota parts involves witchcraft.
The loader outlet blocks are usually included in the loader parts diagrams. That one was found by going to Kubota's online parts and pulling up B2710 and using the related units list to find the LA402 loader.
From there to Messicks to get price and availability. LA402 lookup returned three variants. The LA402 variant did not show the block. Abracadabra - the LA402-1 did.

Thank you, that’s what I figured.
I have tried looking for implements parts lists but I can’t always figure out the correct model number for the mower or tiller or FEL. And I am too lazy to just hunt and peck through all the options.
I do agree that Kubota does some interesting things with their parts listings.

You guys are great, thanks. Here is my Husco valve drawing. My loader just has two hoses, one in the ”in” and one in the “out”. There appears to be a power beyond port and the valve casting is mark so but it’s plugged. So can I simply attach the “in” hose to the out port and the out hose t the return port on the hydraulic block from Messicks? Would it be better to run a third hose from the PBY port to the trans? The hydraulic line already goes there with a banjo fitting. Is there a double stack banjo fitting? Hose does that hose get routed into the trans when there is already a hard line in place? Is there another port or fitting for the PBY hose? Sorry if my questions sound dumb but I’m very capable of many things, just never learned hydraulics.
thanks in advance.
thanks in advance.

Yes uou should use the power beyond port but its not ascsimple ss judt hooking up as v tug hird hose.
Notice items 13 and 14 in that drawing. Notice the "OR" next to them.
One is a power beyond conversion plug. It has to be installed to make the power beyond port work correctly. Do you have that plug? Do you have the installation sheet for the valve?

Just to give you more hydraulic information that helps you understand the system. You can think of it sort of like a string of garden hoses with diverter valves.
The pump is driven by the engine to produce flow through the pipes. When no additional hy implements or valves are added the flow from the pump is simply piped through that block and on to the three point lift control valve. The flow goes through the valve and dumps back into the (transmission) sump. If you raise the three point system (actuate the control valve) the fluid is diverted to a cylinder (or cylinders) that lift the three point arms. That requires the pressure in the pump and pipes to build up to slightly exceed the load on the arms. (There is really little pressure in the pump or pipes before any valve is actuated if everything is connected correctly.)
When you install a (loader) valve you have to route the pump flow to the new valve and then back to the three point valve. You do that by replacing the cover with the adapter block shown above. The pump flow is then routed to the pressure in port on the new valve, it flows through the new valve and out the other port back to the tractor. That is fine until pressure builds up inside the valve when using the three point. That pressure can damage seals on the FEL valve. Installing the PB sleeve allows that pressure to be isolated from the Tank return section of the FEL valve. That is why you need the PB sleeve in the FEL valve.
Then the cylinders have to allow fluid to be pushed out of the low pressure side of the cylinder and return to the sump. That is the tank return part of the valve that needs a third hose connected to the valve to route the fluid back to the sump.
All the pressure lines have to be in series without any tee connections. The tank returns can be connected together to be one port back into the tractor sump. So the tank return line could just be returned to the transmission fill port or some other port that the manufacturer provided.
I’ll post a link to a picture of my old L185F showing the adapter block and tank return hose.

See post #16 in this thread

Rear remote hydraulic on Kubota L245DT
My L245DT has aftermarket power steering..does not have a front end loader. The power steering cylinder is connected to the control valve below the left side of the seat via an aluminum block. How do I do this? Thanks for any help.

So if this loader has only two hoses, it was probably used on a machine without a 3pt hitch so that pressure build up wouldn’t have happened.
More likely used with a dedicated pump. In any event it looks like you can get what you need from Messicks.
Dan
So it looks like part 13 is what I need. Then a 3rd hose from the pby to the trans case. Is that correct?

Its difficult to tell exactly what's what from the parts diagram. Post a couple pictures of your valve showing the PB port and that port on the side.
Dan
Will do. Just finished all the mountin brackets and even made up the front grill guard. Got the headlight bezel out as I’m repairing it.
Attachments
That makes sense. I’ll call messicks to discuss what I need for the valve. I appreciate the help and education you guys have provided. Can I temporarily hook up just those two hoses to the block to test the loader function if I don’t operate the 3pt? I will have to wait on the PBY parts and then get a third hose made up.
