I'm looking for the biggest yoke I can find for the input on my divorced NP205. The shaft is 1.4"/32 spline. I think I can get a 1480. Does anyone know about a 1550 or 1610?

Big Yoke for NP205
- Thread starter ARAMP1

BIG plans?
Yup.
The yoke I have now off the transmission is a 1710. I could go smaller to a 1610. Don't want the 205 to be the weak point in the driveline.

u got enough power to turn a yoke that big?
Remember that the stubby drive shaft is before the reduction of the 205, so you'll have half the torque at the input compred to the outputs in low. Also, the operating angles of the stubby should be pretty much zero, so the ujoints will survive a lot more torque.
I'm looking forward to seeing the torque monster you must have.

Good points.
We'll see. Here's the build thread. It's not updated, but there's not too to update.u got enough power to turn a yoke that big?
As mentioned, that's way overkill for the input side. Really, that's way overkill for everything you're planning.
It's silly, even the 1480 joint won't be the weak link.

With a yoke that big, you need to talk to a driveline shop and see how long the shaft has to be with said joints. The length will have a minimum length to it which might put the 205 further away from the transmission then what you have planned...
Oh? I'm not sure I'm following you. Actually, the RTO-610 10 speed is basically the same length as the SM465 (with adapter), so I have plenty of room. Anyway, please explain.
the amount of space a big tranny yoke takes up + the amount of space the slip shaft takes up + the amount of space of tube w/ weld on yoke + the amount of space the 205 yoke is going to take up is going to be pretty long and most divorce t-case setups have a fairly short shaft and yours is going to be longer then most, just hoping you have the space...
Oh yeah, I got you. Basically, the bigger the yoke is, the more length that the yoke(s) will take up, the shorter the shaft will have to be to keep the transfer case in the same spot.
I was actually wanting to have the front driveshaft as long as the rear driveshaft, but I don't think I want that long of a front driveshaft. Right now, I'm planning on the intermediate shaft will be around 18" (give or take).
I get that a lot.
most divorced case setups have an intermediate shaft length of 12" so 18" sounds about right...

Sorry for the thread necro... but did you find one? I am looking for a 1550 input for my Ford NP205 behind my Allison.
I found a Spicer 4-4-7001-1X but not sure if it fits the 205 divorced input. It's 32 spline is all I know.

That yoke is for a 2.114” shaft. 205 is 1.401”. I think the only way you are going to get a 1550 on a stock 205 shaft is to use a companion flange.

Thanks for that.
I found this:
Northern Drivetrain, LLC: Northern Drivetrain 00105
Northern Drivetrain 00105, Our Price: $147.31, In Stock. Companion Flange - Splined Bore, 1410 series, Ø1.401x32 spline, Ø2.125 hub diameter, 4 Drilled Holes on 4.750BC, Ø3.750-F pilot

with this:
1550 - SPI-4-2-669 - 20 deg max
That should work. Is this for the International?

Holy stalker. 
Yep. 1550 from the Allison to the NP205, then 1350 to the front and 1410 to the rear.

Funny, wrong code - sorry for the ugly guy. I meant the Irate one.
