Definitely not.....lol . I think it's either a Chevy or a dodge. Forgot to look at it.Is that a RR or Bentley emblem ? Maybe its an old silver cloud ?
Doubler, or underdrive, like a black box or a magnum? I’ve been curious about them.Ok. I had to move the doubler's oil cooler from where I'd installed it previously. Took some pics from under the truck, just so I can get back to the posting routine

Mine is a Black box from Northwest fab. That's what I used to adapt the the 6L90e to the 80 series transfer case.Doubler, or underdrive, like a black box or a magnum? I’ve been curious about them.
I’m looking into them a bit, and after reading 1000 posts on forums and talking with both guys, I think it’s fine to have the fan kick on with the pump, but I would strive for a lower temperature in the box. 180 seems hot to me for oil.I forgot to mention that I will install a temperature gauge inside the truck, so I can also keep an eye on the black box's cooling system 's operation.do you guys think i should allow the cooling fan to operate continually or should it only turn on when the pump is on ?![]()
That might be a question for NWF but I think that depends on normal operating temperature of your oil. I’d bet that you would want to have the oil warm enough to lubricant properly, but not too hot to promote the oil from breaking down. I’d put some sort of temperature switch on the fan if it were me but I tend to over engineer things.I forgot to mention that I will install a temperature gauge inside the truck, so I can also keep an eye on the black box's cooling system 's operation.do you guys think i should allow the cooling fan to operate continually or should it only turn on when the pump is on ?![]()
I think NWF will tell him that having a tank at all is a problem, they promote a closed loop from drain to fill plug with a set amount of oil, with a tall hose on the fill, terminating in a check valve that will close in a rollover situation.That might be a question for NWF but I think that depends on normal operating temperature of your oil.

Glad to see come progress on this!!
Maybe true, but they are also based out of a completely different climate and I’d wonder if heat was a problem in BC.I think NWF will tell him that having a tank at all is a problem, they promote a closed loop from drain to fill plug with a set amount of oil, with a tall hose on the fill, terminating in a check valve that will close in a rollover situation.
Kris is super helpful and I believe he is aware of what I was needing. I believe he recommends coolers on all the installs, but just a simple pump and lines, like a power steering cooler, just a little something for a little extra capacity as much as cooling. I will say that the need for the cooler was kinda mentioned after the fact.Maybe true, but they are also based out of a completely different climate and I’d wonder if heat was a problem in BC.
Yes. I did consider installing one also. Just forgot to mention it. I think it's actually important to be able to to turn it on and off manually. I'll make sure to remember that when we get to wiring. Thanks for the comment !That might be a question for NWF but I think that depends on normal operating temperature of your oil.

They actually told me that I needed a tank to add to the Bb's oil capacity , but i do see how having the black box completely full could also make matters worseMaybe true, but they are also based out of a completely different climate and I’d wonder if heat was a problem in BC.
I think I am mistaken on the tank, as you say here. I was pretty sure he told me no tank, just lines but I could be wrong. Just make sure the tank is vented.They actually told me that I needed a tank to add to the Bb's oil capacity , but i do see how having the black box completely full could also make matters worse. I might have to call Chris before doing more. I'll post whatever I find out here for everyone interested in this matter.
I'll look again at my thermostat and make sure it's in fact a 180° or less . There is a thread on here about that specific issue ,and I think everything i got to build this cooling system was based upon what I saw others do with success in it..... it's been too long since then .... I need to go take a look again. All great input, guys !

I have a lot of hydrostatic machines, and the ones that perform the best for the longest keep the oil 110 to 130. In addition the Mack trucks have a transmission and rear axle temp gauges, and the transmission will typically run 140 at the high end, and the rear driving axle will run 110-130, rear coasting will run 110 or so, summertime temps.
In addition to all that, I would double check running the tank into the top of the black box, I think it should be the fill port, with a way to keep the black box from being completely filled. IIRC there are seal problems along with overheating from being a full case.
All just my opinion though, no direct experience with the underdrives. I’ll look for those posts.
