So I’m looking to add a third function to my loader on my 7300. The loader is a 417. I’ve read that if you have seven leads coming out of your hydraulic block that you do have a power beyond port. I’m pretty sure the oversize nut that is circled in picture 2is the power beyond port. Just want to confirm. Thanks.
No, that's not rquite right. Instead of "hydaulic block" it should be, "If you have seven hoses coming out of your
Front End Loader Control valve stack then one of them is probably coming from the power beyond port.
What you are showing in the photo looks like a hydraulic diverter block or junction block. No idea or way to tell what that oversize nut is doing without looking in the shop manual. Yes, it could be some sort of Power Beyond - I've never seen one like that. We need the shop manual.
for the 417 and 7300 to show us for sure what that block is doing. If you have one and post the hydraulic schematics here then we can help with it. It needs to be of your particular hydraulic diverter block and control valve setup. They are all different.
As for the seven hoses, all Front End Loader Control valve sets will have the first six below, some have all 7. Unblocking a PB port also requires a special inside sleeve be installed inside when the large nut is replaced with a PB hose fitting.
FEL control Valve typical hose list:
1. Pressure IN from the hydraulic pump or diverter Into the control valve set. Labeled as IN.
2. Pressure out of the control valve set used to raise the FEL lift arms
3. Pressure out of the control valve set used to lower the FEL lift arms
4. Pressure out of the control valve set used to rotate the bucket down
5. Pressure out of the control valve set used to rotate the bucket up
6. Return flow from the FEL valve set back to the sump. Mayb be labeled as Out, Tank, or Return.
7. Power Beyond - often labeled: "PB"
If you have PB, a hose can go from there to power the IN port at the next control valve in the hydraulic series that needs pressure. That next control valve could be the your third function for the grapple, or a set of rear remotes, or sometimes the 3pt hitch lift arms.
Bottom line is it looks like you can get there with what you have, but need more info.
