Good eye guys, it is a ford divorced 205.. dana44 front with the steering knuckle on the passanger side for a cross over setup.. It was a major low buck build.. Thats why the t-case is welded in solid.. It is almost impossible to get the factory cross member out of the frame without cutting it in half.. That would almost be the same case scenario with a home made one.. I had to use a HI lift jack to spread the frame apart and a 20lb sledge hammer to get the factory one out of a donor truck to put in my wheeling truck.. Then I had to get it back inbetween 2 new frame rails

Also, when I set the angles, I keep the flanges"yokes' paralell and the angle of the shaft 3-4 degrees. You can go more for off roaders, but for dd.. Shot for 3-4 and you will be golden.. Don't want it at 0 because your u-joints tend to wear out sooner, because they are designed to ocilate..

I'm having some angle issues as well with my Divorced unit... I currently have about 10 degrees angle on my 9-3/4" shaft between the 2wd getrag output and the np205 input... not really sure what to do at this point, I was thinking of removing the rubber isolators between the case and mount to allow it to raise up higher a bit but I don't think that will provide the angles I need. I may need to push the Xfer case back a few inches... Too bad I just had a custom 1410 short shaft built for the thing + I just realized the custom exhaust will no longer work!!!

The brownie is going to go away as well. The rear angles are about 14 degrees with the stock 3" block suspension on the rear end.

Drivelines are funnn aren't they, I guess this is a learning process. Definitely have some huge vibes throughout the whole driveline at this point that need to be addressed.

Since we are talking divorced transfer cases, maybe you guys can tell me what is in my 1972 Ford F-250 Hi-Boy.

Every NP-205 I ever saw had just a straight back and forth shift-pattern; 4-HI, 2-HI, N, 4-LO.

This transfer-cases pattern has some sideways movements also, not just forward and back; and, without actually going out and looking at the diagram on the ****, I ??think?? it also has a 2-LO position --- maybe not.

It is a one-stick.

This is definitely a "part-time" case, as the front axle has huge hub-lockers.

What do I have ??

Thanks.

I just went out and had a look at the pattern on the ****, plus I shifted it through the pattern to make sure the **** was the right one.


This is simpler on the **** than my clumsy attempt at explaining it.

Starting at sort of forward and center is HI-LOK, straight back from that is HI, then over left and then forward is N, from there more straight forward and then over right is LO, forward from LO is LO-LOK.

So I guess it does have a 2-LO position.

The truck is 4-speed, 390-V8 I have been told by those who care about such things; it ain't a diesel, so I don't know.





I have this truck ( it looks like new ); and, sitting beside it, is a DRW 1991 non-IC 2wd Dodge/Cummins/Getrag.

The two shall become one.

I am puzzling over whether to try to install the Cummins/Getrag into the 1972 3/4-ton Ford frame, or to mount the Ford cab onto the 1991 Dodge 1-ton frame, then mount the divorced transfer-case and 4x4 front axle onto the Dodge frame.

Seeing as how the Cummins is already mounted in the Dodge, and the later-model frame appears somewhat stouter, I sort of lean toward putting the Ford cab onto the Dodge frame.

Sure sounds like a 203 full time pattern. Maybe someone put a part time conversion in a 203. I put one in once.

BearKiller

That's what I was afraid of.

I didn't know the full-time NP-203s existed in divorced configuration.

Thanks.

Richie O

I have never seen one, but who knows.

PapeCAT

Bearkiller, what does the data plate say? I'd check that to be sure. It'll say np20X

BearKiller

Where on the case will this plate be found ??

Thanks.

The 203 had a strait forward and back patern.

Its not a Dana 20 is it?

PapeCAT

well on my NP205 1972 divorced dodge model it is on the front between the shift rails and the input shaft. It is rather large, you can't miss it. But you may have to scrape away all the years of goo too see it...

Wow thats a weird pattern, whats LO-LOK and HIGH LOK ?

wannadiesel

Locks the diff inside the transfer case.

BearKiller

That's what I thought, but it has been a very long time since I have been in a truck that had a 203.

My uncle still has the 1979 W-150 that he bought new; I need to take a look at his shift-****.



I know that the NP-205 is the last word in transfer-cases, the stick that all others are measured by; if, in fact, this were a Dana 20, how does a Dana 20 compare to a NP-205 ??

Is the Dana 20 all gear driven, or chain ??


I need to get under there with a pressure washer and find a build-plate.

Thanks.
