Changing 4020 158 loader so that I don't use remote on back

2520-4010 · Sep 11, 2020

I have a 1967 model 4020. I'm trying to plumb for a loader. It already has one that is using the remote for power.

It had the hydraulic control lever wired down....that is, it was pulled down and wired in place. That makes the loader controls work correctly...if I reverse the control lever and wire it up, it reverses the loader controls.

My question....which hose on the back would be the one going to the inlet on the remote valve on the loader (158). Would it be the left side of the remote on the back...or the right side?

Or should I just loosen one of the hoses a bit and see which one blows out the most oil when I move the control lever on the dash?

Any/ all help appreciated!!

IIRC RH breakaway barrel has pressure when control lever in dash is moved forward.

Have you considered attaching FEL control valve hyd supply/return directly to tractor hyd system & free up rear breakaways for other uses?

Yes, that is what I'm planning on doing.

Just not sure which hose was being used as the "inlet" on the remote loader valve. It's covered in old
grease and wasn't sure if it would be marked inlet and outlet.

Thanks for the help!!!

Can you post a photo of your FEL control valve. Maybe someone can ID the inlet port.
