From mounting face to yoke face. Please and thank you
@Lil'John You must have gotten your new case all put together ok.
I have a few hundred miles on mine. No cooler installed yet.. I have the parts.. Just been busy selling one house, buying another and moving... Almost done with that.
Bright side is the new place comes with a heated 36x60 toy shed.

I thought anyone watching this thread would like to see this data.
I put a temp gauge in the blackbox last week. This was after a short 20 mile drive... It was actually at 255. It took me a bit to get a pic....
I was really surprised that it created that kind of heat. But I'm glad I got the gauge in it to know...
So this week I put in a pump and cooler. Kind of a quick install. I think as things progress this fall I will change my design some this winter. But as you can see by the pics it works!!! Being as hot as it gets I think the new design will be a bigger cooler...
I am all for ideas. If anyone has any tips let me know. Or if you have any questions let me know. Hope this helps.

For the pump I went with this one. Electric Oil Feed and Scavenge Pumps Very happy with it so far. Very quiet and smooth. A couple things, old school company awesome to deal with. Make sure you order the fittings for the pump to go to whatever size hose you want. I went AN10.
Cooler I went with this one. Universal 19-Row Oil Cooler Not ideal fitment.. But, I was in a hurry, wanted to use it this weekend. I had the cooler from a previous project so that helped in the decision. That being said, I think this winter when the rig is down for avoiding salt, I think I will change it to this one, Universal Dual Pass Bar & Plate Oil Cooler, Large so both fittings come out the same side and its 1/3 again bigger, and lastly, I think the mounting points will work better for my cooling situation.
Northwest Fab said to use Redline MT90. Which I was fine with, except no one local has that to me. So.. Amsoil is close to me, so I called them and they said to use this. Manual Transmission & Transaxle Gear Lube 75W-90 MTG - AMSOIL Which I thought was a bonus since I had some of that.
With the whole system together it holds about 3 quarts now. I thought that was a nice amount of fluid.
Hope that helps.

130-degree delta from a cooler install, geeze, impressive.
I'd be more then content with that. What is the correct operating temperature for the fluid?
Move your sensor over the rear diff or the transfer case for comparison!

@cruisermatt I was pretty impressed with the temp change as well. We did a 300 mile trip this weekend with ambient temps at 75 degrees F and the hottest it got then was 160 degrees F. We had a lot of short runs with stopping and sight seeing. But on the way home is when it hit the 160.
As far as the fluid goes, I wondered the same question. So yesterday I reached out to a friend at Amsoil and he sounded like they prefer it to be about 180 F to keep moisture evaporated off. And after our Sunday drive I would say in the summer that it will run close to that.
I put another hole in the bottom of the Blackbox for the temp sensor. I should put another sensor in the tcase and move the wire just to get a comparison.

the easiest way is to just tap a fill plug.
so will the one for the fj80 fit without gas tank mods?
Are you getting closer to having the 80 series adapters for the BB done any time soon?

Do you have a reservoir or is it not necessary?
I'm assuming that because this pump is a scavenge pump, it doesn't pressurize the blackbox, so the normal vent can still do its thing. Or did you plug the vent in the blackbox, pressurize it with this pump, and vent through a separate reservoir?
I do have a reservoir. I am actually going to add a larger reservoir... I couldn't believe how much the fluid did expand.. It over flowed the small reservoir and helped rustproof the firewall and underside..
I used the same vent out the top of the blackbox. Ran that to the highest point on the firewall and put a reservoir with a filter on top for the breather.
Hope that helps.
Ok, so to be clear, you kept the original black box vent out of the top of the black box, and used the two other tapped holes to route feed and return to the pump. I assume the return to the box has the reservoir in it, and the reservoir is also vented?
Yes, I kept the original vent out the top. That is my line to the reservoir.
On the lower hole on the side of the black box I went to the pump, thru cooler, back to the other side of the black box which was the higher hole(about 1/2 way up the side).
On a side note, with the cooler temps here in MN(it has been in the single digits) the pump blew a fuse. I had it setup to turn on with the ignition and when it was cold the pump could not pump... Now I put it on a switch. So I can let the black box warm up a bit before I start cooling it. I may go back and revisit that in the future. Maybe set it up on a fan control relay maybe?? Not sure yet. We will see how the switch thing works out for a little while.
You're saying yes, but explaining no, lol.
To summarize, your pump system connects to the black box via two ports. The only vent in this system is through the reservoir. Correct?
Lol. Yes it vents out the top through the reservoir. Sorry to be confusing.
A simple thermostatic switch threaded into one of the holes that would complete the circuit only when the fluid temp reached a particular temp, perhaps?
I like the sound of the simplicity of that!! I will check that out. Thanks!

So is it a coincidence that my son Johnny @JohnnyOshow22 is posting up to @Zoverlander today on MUD when Zoverlander and I also traded info on Instagram today on this very topic, instigated by me out of the blue :rofl:? When Johnny's shop learned directly from NWFW personnel that the Black Box...
