Joystick Question Koyker 195 FEL

This photo shows my loader valves. The hyd lines you see are going to the loader cylinders. Where do I attach the new valve/spool? There are lines coming to the valve not clearly... one from the top that I think comes from the pump and the one on the bottom that goes over to another valve that operates my rear remotes.

There should be 7 hoses connected to your valve. You have to figure out which hose is the power beyond, which is the inlet and which is the return to tank. The valve is most likely marked as to what is what. The 4 work port hoses should be easy since they go to the lift and curl cylinders.

The hose from the pump is the inlet, the one going to the remote valve is the PB and there should be another going to the sump/tank.

Rob, is your spool assy mounted on the fender? I have a KM454 with the 195 loader. The valve/joystick is mounted on the top of the loader uprite. It virtually blocks exiting or entering the tractor form the right side .. a real pia!
I'd love to modify the set up if it were possible ... Scozz

Scozz,
My joystick is mounted on the right fender sort of on the front downslope of it....see the picture in that first post. It is still a PITA to get on the right side as the control cables curve outwards from the joystick anyway. I nee to reduce the curve without hindering their function.
My valves are mounted underneath the right fender (inside of the rear wheel) onto a bracket that is wleded to the FEL stabilizer bar which bolts to the rear end.
Here's a picture of that stabilizer bar (in red) for the FEL underneath the tractor where my valves are bolted.

My bucket measures 29" from the cutting edge to the top of the bucket but 32" out to the teeth. Which size grapple should I use? The 28" or the 32" one? Any reasoning/comments behind the choice?

I would go for the longer. By adjusting the placement of the mounting bracket closer or farther from the top edge or making the bracket higher you can make it fit but I believe you will have more room for adjustment with the longer one. I adjusted mine by moving the mounting bracket back and notching the grapple arms so that the arm tip almost touches the teeth when fully extended.

Every bucket and installation is different. Ask the manufacturer for their recommendations.

Gentlemen,

Koyker offers a 3 spool valve and joystick for 3rd functions such as this. However it would not be a turn-key package this unit. You could also add another single spool valve in the series, make sure it comes with a power beyond function, so it eliminate the threat of back pressure to the hydraulic system. You could also add an electonic solenoid switch valve to your current configuration. It would run off an electronic switch you would mount near your joystick and when energized it would allow you to use one function on the joystick to control your valve.

I would choose the #1 or #3 option for ease, number 2 for cost.

Good luck

Sorry to take so long to get back on this one until now. I've got a valve for my grapple to install before I attempt the side links. So here's my question....
On my loader valve there are 7 connections.
#1 being the input that comes from the valve that operates my rear remotes (stock tractor valve) The "out" from that valve goes to the "in" (#1) on the loader valve.
#2, 3, 4, 5 go to the loader cylinders and those ports are sideways/perpendicular to the "in" port.
then #6 and 7 go into the rear hydraulic case to
a) maybe the reservoir or
b) even maybe to what makes the 3pt work?

That's what I don't know...which one is the out #6 or #7?

Now, from the look of my loader valve, #6 is on the side of it (perpendicular to the "in" line) like the others 2, 3, 4, 5, but #7 port goes out the opposite side ...inline(parallel) with the "in" port, so I'm guessing that's the "out" line? I was hoping someone could help me there?

Here's a picture that might help. Try to follow this... The "in" port is on the very bottom and you can't see it, but it goes straight up. You can see the other 6 ports, 4 of them go to the loader cylinders. #6 is the one perpendicular to the "in" and #7 goes straight out the very top of the vlave. Both of them go to the hydraulic casting.

This picture is from the front right side and shows the 3pt controls (draft and position). To give you some perspective of this photo, you can see the adjusting knob below the seat towards the right. See the metal hydraulic line that is bolted to the hydraulic case? What does that line do? That comes from port #6 (I think) See the rubber hyd line to the left of the position control levers? That one goes to the back of the hydraulic case. What does that one do? I think that may come from #7 on the valve?
NOTE: I may have the ports mixed up because I don't remember whether port 6 or 7 went to the steel tube or rubber hose, but in any case, it's port 6 and 7 that go to the case.

This picture is from the rear. You can see the metal hyd line attached to the casting and then look in the very lower left corner and that is the rubber hyd hose that goes into the casting.
If you can tell by that which of those 2 should be the "out" on the vlave...the metal line or the rubber line, that would help me determine which is "out" on the valve? If I've managed to confuse, please let me know and I'll try again.

Last thing, would it hurt to connect the grapple valve between the rear remotes and the loader valve? Since I know which is the "out" for sure in that case. Would the loader suffer in performance because it's running AFTER another valve? Or would that be OK. If so, it gives me a choice where to put the new grapple valve in series.
Also, where do the wires from the switch go? How do I hook them up to the valve and tractor electronics? I went with option #2 and got the third function soleniod valve.
email from Nelson @ WR Long:
The valve is our part number VALDO3S2C12D-35
The Subplate is our part number VALSUBPLATED03
and the Handle is our part number G3-0100HANDASY4

Thanks,

Are you saying that the tractor is plumbed so that the rear remotes are BEFORE the loader valve? Rear remotes are usually plumbed so that they are AFTER the loader valve. The circuit is typically sump to pump to loader valve to aux valves (remotes, solenoids, etc) to 3pt to sump.

#1 is the valve's high pressure inlet.

# 2, 3, 4, 5 are the work ports that go to the implement cyliinders. They are matched pairs so be careful on how you connect them.

As for #6 and #7, one will go to the transmission sump/tank and the other is the power beyond which goes to the next valve in series (the 3pt). You will have to figure out which is which because connecting them wrong will cause the last valve in the circuit, the 3pt, to stop working.

You can connect an additional valve anywhere in the circuit. Just remember that if you want to operate more than one function simultaneously the first valve in the circuit will have priority for any fluid flow.
