The return should go to the filter cover. If you don't already have a ported filter cover, I would get one. If you return back to sump, the main pump may starve for oil .

 

Thanks JD.
Any thoughts about where I can find a T31170 filter cover?

There's a ported filter cover cheaper than the T31170. The PN is L55982 @ $70.36 see photo below.

 

Thanks Jim.
Found one thru Amazon. It's on its way to me.

Any idea what size flares on the running tee fitting for the pressure line? I think they're #10 (5/8") but wanted to make sure.

The pressure line is 1/2" or JIC-8 Rather than use the parts JD shows get a -8 JIC swivel TEE. Male/Female swivel on the run, male on the branch for your loader valve hose.


The ported cover inlet will be ORB SAE-12 to JIC -10, then the TEE drops from JIC-10 to JIC -8 at the branch for the hose. Only reason you need a TEE at the filter cover is if you have something else returning there too. MY SCVs also return to the fitler cover.

 

Got my fittings, filter cover, tee for pressure side. Now I need hoses and the quick connect fittings to hook up to the loader.

Should I add a hydraulic fluid cooler to the return line near the radiator?

Tractor has the blank panel on right side where factory cooler goes, just not sure if I need one. I'm thinking yes as driving more cylinders will create more heat that needs to be removed from the fluid as I work the loader on it.

My 2030 has the factory oil cooler, so I can't say if you need one or not, but JD felt it was needed on mine, or they would not have gone to the expense of adding one to all 2030s.
