At what point would the T 136 case come apart? Can't find the max tourqe ratting for it here or any other sites. Would 600 ft two be way to much?

Not sure about torque but it can handle 200 hp at 2800 rpm all day.
They can handle gobs of hp and torque more than 600ftlbs. I've seen one in a truck with an 8.3. Even can twist an output shaft on one. Make sure it's an air shift case though.
I'm sure @Jeepsinker is making more than 600ftlbs from the 6bt

Yeah the one behind my Cummins is holding up fine. It'll hold up to more torque than the transmission will. I have zero concern about breaking my transfer case, and no plans to upgrade it.

That was my next question, is the transmission as strong. Guess not. I'm always watching jeepsinkers YouTube videos when I'm board. Love to see him do a power steering hf54 conversion. By the way if jeepsinkers reads this, did you ever find a thicker flywheel? I know in your video you wasn't pleased with how far you input shaft went in.

When I get back I'll be installing power steering. I didn't find a thicker flywheel yet but I think I may be able to use a dual disk clutch instead.
For what it's worth, the transmission is plenty strong as well, but I do believe that the transfer case is stronger.

Well, our transmission actually does act like a torque multiplier for the engine. So, for the 3053 in 1st gear, at 5:1 - the transfer should hold all day long at 2000 ft-lb, at least. I know it does - and much more than that.

instead of using a SAE#2 to SAE#3 adapter ring, is there a SAE#2 clutch housing that will fit the spicer 3053?

A #2 bell for the 3052/3053s? Not that I know of... (?)instead of using a SAE#2 to SAE#3 adapter ring, is there a SAE#2 clutch housing that will fit the spicer 3053?

the one off a 5 ton wont bolt up?

No, 5-tons would use the bigger series Spicer models 6352 and 6453. Totally different beast, at twice the size of a 3053...

Since nobody else has asked yet, why?

The pilot bearing would be the same I think. The Spicer 6000 series was used on the LDS in the 5 tons. So I think a 6352 input shaft would fit the 6BT?

Sure, with the right clutch and an SAE2 bellhousing.

Same as what? Not the same, if you are referring to the 5-ton Spicer vs. the Deuce's 3053.

Can confirm for sure. I'm just finding this out the hard way. I got a LDS motor, but it looks like they put a LDT crank in at some point because it has the .750 id bronze bushing instead of the 30mm id bearing listed for the 5 ton. I always thought the motors used the same crank. I was apparently wrong.
They sure didn't make drivetrain modifications easy on these things. Now I get to choose between machining the fso6406 input shaft down, or making a contraption to bolt to the clutch housing so I can fire the engine up, feed a cutter in, and bore out the crank, or, making a flywheel spacer and clutch housing spacer/adapter.
The FSO was only available with SAE#2 clutch housings and pull clutches apparently, so figuring out how to convert all that is my next hurdle. It's probably simpler than it looks, but no one lists measurements of anything anywhere, so I can't do anything until I've gathered all of the parts. Just have to find a clutch housing next, or decide to modify/adapt the one off the 3053.

It probably has a bushing adapter pressed into the crank. While I'm not 100% positive, I don't think they would've had a separate crank for 5 ton and 2.5 ton applications. Bushing/ bearing adapters in crankshafts are very common.

I did more research after this post and it looks like a 62mm od bearing gets pushed into the flywheel on 5 ton applications, which is cool. Now I just need to find a bellhousing and figure out if the 5 ton release bearing setup will work.

Exactly. It takes a 6202 LLU (30*62*16, sealed).
BTW, MF cranks are all the same, for the various models. Not so the flywheels.
