Loader Hydraulics Setup/Power Beyond

[amschind]

I have the mounts for my new to me Westendorf TA26 mounted up on my M6800, which required some die grinder surgery, a come along and a farm jack. But it's mounted. Next step is hydraulics as this loader didn't come with a control block. I'm very much a novice with hydraulics, but getting this set upis a great learning experience so that I know how to maintain things.

I started by making a dumb mistake, adding an extra set of remote ports. I then came to understand that these will only ever respond to the valve built into the remote block, which negates their utility as the hydraulic fluid source for the loader control valve. So I got that installed and now have 4 remotes but am not closer to a working FEL. Looking deeper, it became apparent that the FEL control block runs off of a feed line from the big hydraulic block on the back of v the transmission/PTO/3 point arms, but I started to get confused by the tank and POWER BEYOND outs.

It seems like the power beyond port allows the loader control block to pass hydraulic fluid through so that the same fluid can power the 3 point arms, though I am still hazy on that exact flow path. I am also unclear on the need for tank and power beyond vs one out to power beyond. I want to be more clear on the relationship between the tank and power beyond outs, specifically what the power beyond valve actually is and how a separate route to the tank would not siphon all of the flow away from a high pressure line out to the 3 point control arms.

Basically my crude/inaccurate mental model is that the tank port is basically either a "leak" T'ed into the power beyond circuit or an emergency flow path for a relief valve, but I don't think either of those statements are accurate.

Here is the valve block I have and the power beyond valve:
Magister PB valve
Magister 2 spool open center control block
Any help appreciated.

Pictures of what you have done do far would be extremely helpful. I am assuming this is an open station tractor. and presumably you are going to mount your new valve on the right loader tower like Kubota does with their loaders.

Now for the plumbing. You are going to tie into the hydraulic outlet block nest to the factory rear remote valve{s}. The parts diagram for the outlet block is shown below.

1. Remove plug #140 and run a hose from that port to the P inlet on your loader valve. That is the pump supply going to the loader valve.
2. Remove plug #130 and connect that port to the power beyond (N) port on the loader valve. That is the power beyond line that returns the pump supply to the rear remotes.
3. Now rotate the selector valve #80 to the full extent of its travel. That diverts the pump supply that is currently going to the remotes out to the loader valve. Your owners manual should have a section describing all of this.

Now here is your loader valve and plumbing described above. Fittimg #70 is the hose going to the P port on the loader valve and fitting #60 is the hose from the PB port on the loader valve. The next and final step is to connect the T port on the loader valve to the location #90 on the back of the hydraulic housing.

Thats all there is to it. Study the diagrams and mull on it a bit and then we will see if we can answer any questions you may still have.
