Np205
Hey everyone -
I've got a lead on a spare / replacement NP205 - it'll be going into a 74 F250. The person selling it does not know what it came out of. From the plate info and the pics can anyone tell me if it'll work? I'd compare to the one installed but everything but the model has been worn away on the plate.
Model 205 Ratio 196
Serial 3 15 76
Assem NO 3987901
Thanks!

Less intersted in the data plate. The 205 is pretty much the same regardless.
Only a couple of variables here, Ford, or not. Then whether it is divorced or married,and after looking at your case, this tells me that this case is not a ford case. The drop is not on the correct side. The second pic is the output and this is on the wrong side. Second, the coarse input and strange pattern for the adapter tells me that this is a married case and that it is a chevy.
Your application will be a ford, divorced case, and has to have three yokes. No splined shafts like the one pictured. Your 74 will require a divorced 205, so anything other than this will simply not work.

That evil bay transfer case is the correct ford divorced 205 transfer case. Not a bad deal either I might add.
Converting a married case to a divorced case does not work. The cases mount differently, and the married case does not have the giant holes or castings to accomodate any fasteners on the driver side of the case.
Now, the second reason would be the front of the case and the input shaft. The input shaft on a married case is "female" and not male, there is no way to install a yoke to it.
The same is true for the method in which the bearing retainer is actually bolted to the case. The case is drilled for the adapter and not for the retainer so retaining the bearing would be close to impossible.
This is far more work than it is worth.
Get the correct case and all of the troubles will be over. While reasonably rare, these divorced cases are out there, and not all that expensive.

This is a good question. I used a bearing supply place when I lived in Arizona. See bearings are sized by ID, OD, and thickness. Find, or use the numbers on the original and a bearing supply store will get you what you need. This can save some time and a little cash. The same is true for seals.
Now that I am in So Ca, there are plenty of local shops that carry complete re-build kits. Tri-County Gear is where I usually buy complete kits, or even just seal kits.
I have used Jeffs Bronco Graveyard too.
Know that many kits only supply seals for 1310 yokes. If you use larger 1350, 1410, 0r 1480 joints you will be shopping again. This is part of the reason why I buy individual components.
If you are taking a 205 apart, also be aware that the aluminum bearing retainers are fragile and will break very easiily. Also note that these retainers have an oiling hole, and has to be re-installed correctly, in order to oil the bearing. Failure to notice this will result in a failed bearing.
