2240 Hydraulics Questions

M5farms, i think this is the port you are talking about.

No that's not the port I was referring to. Port you're pointing finger at is just an opening to sump. Port I was referring to is under foot rest at rear of priority(pressure control) valve.

This is how mine is plumbed.

Do you realize that galvanized pipe fittings does not have a pressure rating anywhere close to 2250 psi? It will be alright for return oil but I wouldn't use it for pressure.

It's possible it might fail and possible it won't . If it does I will replace it .

Here is the RETURN from the SCVs on my 2030. It's my understanding this was some type of optional kit It goes to the optional ported oil filter cover

You're correct the hose from scv to ported filter cover was a "very good option" that I never personally witnessed.

I am going to offer a different opinion for the plumbing the return line for the post driver. In my experience, the driver works much better when return goes to the pipe plug fitting the original poster showed. When returning to the filter cover, flow is restricted too much and the ram does not drop fast enough to efficiently drive posts. At least in Maryland with Hard clay soil and shale rocks. The small diameter cylinder on the driver does not require a large volume of oil that will starve the pump for oil when returning to sump. At least it won't if closed center valve is used on the driver. Open center valve will not work well at all if returning to sump.

Thanks for clarifying the return oil routing. My knowledge of hyd post drivers is very limited.

Shaver recommends returning to the trans fill port (cap removed). Unless the tractor will be dedicated to post pounding (think fence installing company) I would just bungie cord the return to the trans fill when installed.

As always, you guys are a wealth of knowledge! I have heard several times now from different sources to return the oil through the fill cap. The plug I pointed out in that first pic is going into the same cavity and is about 1.5" diameter. I think i will find a 90* fitting i can screw into that port and then tightly hoseclamp my return hose onto. This should help keep dust out of the hydro oil.

The last piece of this puzzle is the closed center valve for the pounder itself. This is an old shaver pounder. Would they carry the part i need? Is it a generic part that could be acquired from any hydraulic or tractor shop? Is there something i could simply add to the current pounder valve to convert it for closed center use?
