Plan 'B' for Koyker loader on 656 (pic)

Thanks for all the previous tips on what to try next for getting the Koyker loader to function. I have changed filter/fluid, over filled fluid, and operated steering and loader enough to purge air but it still only works like a loader should 10% of the time.

While reading over archives again and using different search text I came across some pretty old posts that reference diverting the high pressure flow PRIOR to the rear remote by installing a 'T' to supply the loader valve directly. In the examples in the archives the return fluid was sent to a connector that had been 'added' to the hydraulic filter cover (via welding or whatever method worked best). I'm about to that point for two reasons.

#1) I can't get it to work consistently as it was configured when I bought it which was simply two hoses connecting to the 'in' and 'out' on the loader's Cross valves to the tractors single rear remote.

#2) When I engage the rear remote to try to send fluid to the loader the engine lugs noticeably the whole time the valve is engaged. I just don't think that is healthy for the pump and some of the older posts indicated dealer's said you could ruin your pump this way?

There are two lines it looks like I could plumb into. It looks like it would be easy to replace the elbow on the one that feeds the rear remotes with a 'T'.

Does anyone know anybody that has actually done this? What can I screw up. I would get a donor filter cover plate for the other side to do the return line surgery on.

This is going to be a cool and very useful tractor. I think it's almost there.
