1600 Power Beyond Setup

Well it only took about 7 months since we put the loader on to get the 1600 set up with power beyond and a loader valve. We have just been running it off the remotes which gets the job done but sucks compared to what a real purpose built loader valve will do. Only crappy part was trying to figure out how to plumb it up since all the power beyond ports are on the left side of the tractor and the valve is on the right. This was the cleanest setup we could come up with. Steel lines from the power beyond ports, around the front of the hydraulic unit, to bulkhead fittings mounted to the rear of the right hand floorboard, then hosed from the bulkheads to the valve. Keeps everything out of the way of your feet and doesn't have a big wad of hoses going all over the place.

The front port is pressure out giving the power beyond, the middle port is the bypass return, and the back port below the hydraulic filter is the tank return. To make the whole circuit work you have to pull the priority valve off the front of the hydraulic unit and remove the 1/2 inch pipe plug that's behind it. You put in a 3/8 pipe plug about 6 or so inches back in that oil gallery between the pressure and bypass return ports to create the power beyond circuit then put the 1/2 inch pipe plug back in.
 
That's on dad. He has his own industrial and mobile hydraulics business so he does stuff like that for a living. Although this is more on the walk
in the park side of things compared to what he's normally working on.
 
Is your dad using a powered tube bender or a manual one? I have to bend some metric tubing to plumb a couple auxiliary hydraulic circuits on my excavator. I'm hoping a manual bender can do nice work like you show here. Could run it all in hoses, but sure like the clean look of hard lines.
 
He has both. A bench mount manual greenlee and a bench mount hydraulic greenlee. He did these on his manual bender which is his
workhorse to begin with.
 
That is sharp Looking! Nice job to both of you. What type of tubing is that your father used? I am looking for something to use for the oil cooler lines and Hyd. lines to the front of the 1800 we are re-doing.
 

Some spool valves have a separate "exhaust" or "return" port that goes back to the tank vs its power-beyond port.
 
Hi, I just was wondering where you go to get. Hyd. Lines made like that. Beautiful job. Thanks DtK
 
There are valves out there that only have two ports, one in one out, that claim they can be used for power beyond and they will work, But your results will vary. Without the third port as a true tank port pressure builds in the drain passages at the ends of the spools and if it is high enough it will cause the spools to shift and your loader or what ever you are operating with the power beyond valve will drift one way or the other. I have had three tractors that this has been done on by the owners and had to install a bypass valve around the valve to stop the drift when the tractors were being used for other things. Hope this explains it.
 
Looks good, only thing I might do different is where your quick couplers are for your loader valve, put 90's on there so they point forward instead of up. You'll have less problems in the long run with wearing out couplers and o rings.
 
That's what I need to do to my 1600. Maybe I can get to it this summer when I take care of a few other issues. That looks clean.
