Viewing the attached hydraulic diagram of my machine, and the diagram for the "auxiliary" hydraulic kit (which I don't have), where would you tie in a supply and return for a new valve?

I want to set up a valve with some quick connections on my loader arm for a grapple and auger. (both factory options, but long since unavailable as direct bolt in)

Thanks!

It doesn't look like you have a PB port, so you would have to add a valve with PB before the FEL valve. The new valve would be the aux circuit. You could probably use something like this that has PB.

Attached is a schematic of the actual loader valve. So this doesn't have a PB port,and the return port cannot be used as such?

I'm curious what #37 is. It is right next to the 'out'.

Thanks!

What does your parts manual say about that plug. It could just be another tank outlet . Are there any marking by that plug or port.

A lot of valves have two IN/pressure ports and OUT/tank ports.

Who makes the valve and what is the model number?

Can you show a picture of the side port?

Looks like it says "Grasser hydraulics" on the body, and the only number I see stamped is "J6"

Pictures attached.

Thanks!

Item #45 in the second (right) drawing with an auxiliary valve added looks like it may be power beyond sleeve, plus there is a second tank valve added to the main valve. Look into that item descripriton, see if it is available. I think JJ has best idea. Your going to have to get an auxiliary valve anyway so get one with Power Beyond in it and hook up ahead of the main valve.

It could be a PB outlet, but the only way to tell is to take the plug out and see if the OUT port is open to the side port. If it is, a PB insert would block off the gallery between the OUT and the PB port. Maybe if you cleaned it up a bit you might see some more marking.

Does the parts manual offer a PB option. or suggest what the plug is for.

I just looked in the book for my loader, and my loader valve is a Cessna, and it looks very similar to yours. The plug on the end of my valve is a PB outlet.

If #19 is your aux valve, you should have outlets on the front of the loader. The output from the aux valves would feed an auger, or a grapple.

My skid wasn't ordered with the aux kit, so I don't have any of that.

Perhaps I will just get a valve and put it in before the main loader valve as you suggested. I would use the PB port rather than the Tank port on the new valve to feed the loader valve, correct?

This machine was made by Erickson from 1969 until I think the early 80s. It was a model LC4D, then Ford picked it up and called it the Ford CL340, then it became a new holland. Mine is a 1976 Erickson branded model.

It's a neat little machine, 30hp wisconsin vh4d, 57" bucket.

I think the second drawing is for "optional kit" that is not on the loader. In photos of the valve you can see the retrun hose is secured with hose clamp, so no pressure, but just below it on the left side is a large Hex head plug. This would be where the PB sleeve would go in for supply to the aux valve.

That is the same engine I have on my Case trencher and BH.

Check out that side plug, that may save you a lot of work, as you just add the new valve in series. You have to consider priority when using hyd valves, as the first valve up stream might take all the fluid.

My thoughts also.

How is it ? I picked this machine up in November to replace my Oliver 550 for digging/manure duty. The first engine lost all compression. I picked up a very low hour used vh4d for $300. I had to swap the top mount distributor and a few misc things, and did a pertronix ignition. I set the timing today to spec (23*) and it runs pretty good. I had to rebuild all the throttle linkage to the foot throttle. It's a little weird having a foot throttle rather than a governor, but that is how it was built.

How is yours set up?

So if that plug is for PB, I hook it up to the in side of the new valve, and then move the tank from the old valve to the new valve, correct?

I wish I knew more about hydraulic systems.

I do have the service manuals and specs in the books, but the diagrams don't tell me much. perhaps I should scan them. I did find out that the pump is actually 3 pumps, each port is 15 GPM, and I think it said 3,000 psi. Two for the drive wheels, and one shared for the loader.

My only complaint about this machine, other than the slightly odd foot throttle, is the foot brake. Apparently this was built before they figured out how to make it auto stop (like a bobcat). It has some big 1 ton truck size drum brakes, a master cylinder, etc. WHen I got the machine the master was junk, so I found a clark forklift master new for like $40 online. It was almost identical. All I had to do was oval out one of the mounting holes on my drill press and it bolted right up.

The only problem with my engine was the fuel pump had some white powder in it. It was trashed, so got an electric fuel pump. The hyd are strong, and it drives well, but I will need some new hoses soon, as a lot of them are brittle and cracking.

All tank hoses go to tank, and you can tee into them as they are low to no pressure.

If that port is the PB, you order a PB insert and screw it in and connect that outlet to the IN port of the new valve. The only problem is knowing the manufacture, and if parts are available.

anesthes,

What you have is a Gresen/Parker SP monoblock valve bank with a conversion plug (hex plug you show in pics)

There is a power beyond sleeve available for this valve, check this out.....You may need to copy the entire file on your computer for great reading....it shows cut aways to explain the dilema of understanding how these are manufactured

Check out page 30......4-20.....that's the PB plug you need to run an additional valve downstream of your setup .......look at pages above it and below and it should answer questions you have.....

on page 7 you'll see the PB Sleeves......

ie: Part# K-2021C

Leave the current tank retun line where it is, this is need to dump oil when the relief valve opens. From the Power beyond plug to inlet of new valve then tank return from that valve can tee back into the tank on the original 2 spool valve. Just the way it is drawn in that parts drawing you posted.

Howdy Neighbor!

Thanks for the link and info. I'm gonna get to reading!

Ah, I didn't notice you were so close.....

I may even have one of those PB sleeves at work, I'll have to check tomorrow at work.......

Good reading, look at the cut aways real good, the visuals are priceless....

Thanks. Yeah it's good to have some documentation.

I was just out moving dirt with the machine. Must be too hot out. It's running a bit hot, and it knocks occasionally at idle and stalls.

It would be nice to have a brand new kohler. It's kind of hard getting used to throttling it with my foot, using the controls, but then backing off the throttle to keep from overrevving when I stop the controls. ugg.
