NP205 question

[ddarnell]

Are all NP205s the same? Will a unit out of a Ford or Chevy work in my 76 W200? I would imagine the input is different for each brand, but is the rest of the unit the same?

Ford is a drivers side drop, Dodge & Gm were passenger side drop.

Dodge used divorced version 1969-74. Married version 1980 til possibly 93, mostly in 1 tons.

I think GM only used a married version. Ford I think had both.

They are all different as far as input shafts/splines/adaptors. But I believe the innards are basically the same. Low ratio is 1.96:1 in all of them.

If you are using a Dodge engine/transmission it's is much less hassle to use a Dodge version of the NP205.

New Process at the time was owned by Chrysler, so yes GM/Ford/IH used a Chrysler made transfer case for decades, the ultimate flattery.

I learn something new every day, thanks for the info.

Good info, but check your dates, I'm pretty sure that married 205's could have started as early as 1978?
The reason Dodge and GM created New Venture Gear from New Process Gear
was GM couldn't take the embarassment any longer. After the Chrysler/GM divorce, Chrysler once again owned NV, but Daimler quickly sold it to Magna and now I believe they are gone and the new electronic cases are Borg-Warner and others. A sad page in Chrysler history and another mess caused by Daimler.

Well best I can figure, GM had married NP205's during the 70's, as an option to the full-time NP203. In other words, GM offered both 203 & 205 during the years 1975 til about 1980.

Dodge was strictly NP203 (married) from 1975 thru 1979, except in the W600. Married 205 began in Dodges in 1980. I think the NP208 appeared in Dodges in 1981, so both were offered 81-later. But I think the 205 wasn't in the 1/2 tons.

I have a owners manual for the 1979 light duty Dodge trucks. Only the NP203 is mentioned.

I used to tell ford & gm guys that back then and they'd look at me like I had an iguana on my forehead.

Bucky, do you have a lot of reference material or is this all cached in your mind?

Honestly on this particular subject, its mostly in my head. So much misinformation is out there in Chiltons/Haynes manuals, at least concerning what years certain t-cases were used by Dodge.

Concerning Dodge's use of the NP205:
1969-1974 was used in W100,200,300 as a divorced setup.
1975-79 not available in Dodge.
1980 used in all W series
1981-later used in some W250's & most/all W350's until the 241 came out.

Some Fords of the 60's used Dana's & maybe Borg-Warner's too. And GM's had a Rockwell T221 somewhere in the 60's.

I have owned/read alot of reference books over the years. I wished I still had most of them.

I have owned a dozen or so 1972-1979 Dodge W series trucks. I am comfortable working on them.

IH light duty trucks

I do not have the answer to this specific question, but just a point of interest (maybe??).

I know the IH PUs from 1965 through 1975 used the NP 205 as a divorced setup in their 4X4 full size vehicles. I do not know what they used in the Scout. But in the 1/2, 3/4, and 1 ton models of Travelalls and PUs of this time period they used the divorced NP 205. From a production standpoint the divorced set up was an easy solution to mating it with any of their transmissions (3 speed column stick, 4 speed floor shift, 5 speed w/OD floor stick, or the earlier Borg Warner automatic, or the 727 torqueflight beginning in about 1970).

The IHs typically had the 205 drop to the right side and by placing the transfer case further back on the frame than a married setup, they could use a longer front driveshaft, eliminating the need for the double U joints my 86 W250 Dodge has on the front shaft. The longer front driveshaft had less angle on the U joints. All of the IHs I had from that time period sat the body lower than my Dodge, so the driveshaft angles were less.

The Scout used the Dana300, same as Jeeps from that era, with as you noted, different "indexing" to increase the drop.

[712edf]

Paul is correct. The IH NP205 is almost identical to the Dodge version.

If a divorced transfer case is mounted centered between the front/rear axles to where the front & rear driveshafts are equal lenght, it would be somewhat economical to have a single spare shaft that could be used on either end, should there be a u-joint/shaft failure. Old school off-roaders did such.

Chrysler also owned Carter and DANA with the NP new process

so a mid80,s chevy 1 ton dually with with a dana 60 front and a dana 70 rear with a NP 205 t-case a 350 with a Carter carb is pretty much a dodge truck

Yep, and I've had to do that once when I lost a rear driveline in South Dakota. That Capitol City (Pierre) didn't have Dodge parts!
So we drove in FWD all the way to Denver. We could have swapped the drive line as they are identical, but we were lazy....

I'm not sure about Carter, but Dana had been an independent company, until recently, for over a 100 years. They were a tier one supplier to Chrysler but never Chrysler owned.
