Theoretical topic: 203 Range box behind 205?

[MOBK5]

EDIT: Didn’t see the forest for the trees. Mods delete or whatever you gotta do.

I’d like for this discussion to stay on the topic of forces and tolerances, not the cost of custom or one-off parts.

What are the reasons that this doesn’t exist?

Can the 203rb handle the reduction from the 205?

Why would you want to do this?

Good question.

The opposite is used regularly, 203 range box attached in front of the 205.

Not including the machine work, placing just the np203 range box behind the np205 would only provide gearing reduction to the rear axle. So unless the vehicle is only in rear wheel drive, parts will break.

Says theoretical in the title dude.

Lol that solves it. Holy hell I feel like a dumdum.

Keep in mind your Vendor does transfer cases for a living. Was a pretty legit question

So aside from the whole “only driving the rear axle” part, what was the end goal that having the 203 in front doesn’t obtain?

I got caught up in the details of balancing the drivetrain better but failed to even think rationally and realize that I’m stupid beforehand.

What do you mean by balancing the drivetrain?

And I like theoretical questions. This came up once before and we were told the shaft in the 203 would likely not survive the underdriven input

I don’t. Apparently my brain never fully developed. Thanks for the nip in the bud.

I meant more rigid. Less weight hanging off a 205 instead of a heavy 205 hanging off the range.

In that aspect, (not for our application) understand a dana 18 underdriven by a Quadratrac planetary rerouted back into the d18 to feed the outputs.

There's several of them out there in prototype land. It's called a Kluge V. I think Marlin was going to buy the rights to it at one point

 

[ChrisPerry]

If done behind a four banger, yes. If done behind a blown 600ci+ monster motor, less likely. It's a matter of total torque the range box actually sees.
Google, stacked 203 range boxes. There's a guy that did 3 range boxes then a 205.

Google'd triple stack...this is what I got...

no use of course, but now I'm hungry!!!

carry on...
