Adding hydraulics

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.

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.

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.
