In order to accomplish a NP205 with both offset and centered rear outputs, it's necessary to use the offset front and rear output shafts of a NP200. That's the M37 and M715 transfer case. Also, the front wheel drive shift rod and fork must be replaced with the NP200's. The end result is a NP205 case with coupled centered and offset rear outputs and shiftable four wheel drive in high and low ranges. This could be used in a Land Cruiser with a HD drivetrain (like NV4500). In my case I'm going to use it in my M37 coupled to a NP203 reducer box from Wagoner (3.2:1). The reducer box is from a divorced Ford application so the whole 200/205/203 will be divorced from the Clark 280VO 5spd.
Anyways, it works.

Let's see some pics. I'm interested in this setup.

Don't have any pics but it's really simple. You have to replace the front output shaft and that big flat 8 bolt cover with the NP200's two front and rear output shafts and the NP200's rear bearing retainer. Same bolt pattern. And the NP200's 2WD/4WD shift fork/rod. The 205's high/low shift rod/fork stays.
The key ingredient is the NP200's two-piece output shaft. I couldn't use the 200's E-brake on the centered output becuase the shift dog teeth are male on the 200 and female on the 205, so the input shaft/center output had to stay all 205.
The other key thing is that the idler shaft and all the gears in fact are totally interchangeable, and the 200's outout shaft and bearing retainer fit perfectly in the 205 case.
It'll have two separate shift levers, one for high/low, one for 2WD/4WD. And of course one for 3.2 ultra-low (184:1 in my case). Hmmm, I could put a Klune in front of the 203 and go 500:1....
Charlie

Hey, I thought you could do a front high-neutral-low and a rear high-neutral-low kinda like the atlas t-case? or can you not do this on a dual rear output Np205?

Not enough shift positions on the shafts. Here's what you get:
2WD high and low, both rear shafts
4WD high and low, all shafts
No front WD

oh ok, but on a normal 205 it can be done. cool tho. now what are you going to do with that extra output?

Well of course the M37 has an offset diff. I'll use the centered output for a Jesse E-brake. But obviously this is the way to go for a 6X6, though if fully divorced without a doubler is needed just a plain old NP200 has dual rear outputs.
Charlie

Little off the subject but, how are the prospects of finding a Cruzah up in the Anchorage area, FJ40 or 45? Can you run across to Canada bring back a Cruzah? A nice 45 with a diesel..... :skull:

My DD (other than diesel M37) is a BJ40 I bought new in '79, back when border crossing with Canadian origin rigs was simpler. I found a mysterious '84 BJ60 in the classified ads about 3 yrs ago which I snapped up and now my daughter (student at CU in Boulder) drives it - OME, lockers, 4.56s, 34s, F/R winches, 3.04 low range gears, H55F...
Charlie

is there any possible way to set that up to disengage the rear offset output seperately? I'd love to be able to do that to get a pto output in the rear

Not that I can think of. But you could always run a PTO off the standard 6-bolt cover and face it rearwards.
Charlie

yeah I know I can run a pto off the case or the tranny (sm465) I was just looking for an easier way as I am having no luck finding the pto drive for either right now

What are the size/ spline counts of the NP200 output shafts?

1.375" 10 spline.
Charlie

This could be done with 205-only parts by taking the input shaft and center output, and rear bearing retainer from the "top" of a DIVORCED NP205. This would be to get a shaft splined for a yoke. It would be necessary to machine the teeth off the rear input gear so the gear didn't engage the rear idler gear in the offset position. Might work if the shift dog/clutch still engaged.
The rationale for doing this would be if you wanted a fine spline front output or if you had a pile of NP205s around and no NP200.
Charlie

Bringing this thread back from the dead...

When shifting into 2wd, does the rear output in front of the front output get disconnected as well?
Thanks,
Mikel

Charlie, I like it, two+ years to reply! :D

Also this is a great thread, I have read this and others many times and some of this info even exists on my website...

doh!

did anyone ever get pics or more details?
I am looking into doing this for a 6x6 conversion

hey charles how are you doing man ? i have not heard from you for quite a while- Jess

I'm still trying to confirm if disconnecting the front offset output will also disconnect the rear offset output behind it.

In this thread it has been said it can't happen, but that it's possible in this one http://www.pirate4x4.com/forum/showthread.php?t=14218&highlight=daul

Which one is it?? :confused:

Thanks,
Mikel

I also have put the twin sticked 205 with M715 200 offset into my '74 FJ40. The center rear output is still effected by the range shift rod and has three positions high/neutral/low. The 4wd or 2wd shift rail only effects the front output, it only has two postions front output engaged or disengaged. The offset rear output is always engaged no matter what position either shift is in, if follows along with high or low range, basically whatever the intermediate gear is doing.

PaulC

Thanks Paul. Is there any easy way in which that offset rear output can be disconnected?

Mikel,

The offset rear will always be engaged to the intermediate gear. I tried messing with the range shift rail to disengage both rear outputs and didn't get it to work. The offset output is either high or low range. Is this for the tandem axle M715 your building.

PaulC

Mikel,

PaulC

Yes. Thanks.

Mikel,

How is it coming along? Send me some pictures.

Hello Paul,
I have finished all the link brackets, both on the frame and axle sides. But I am waiting to get a larger 220V MIG welder to weld them in place. I can't get good penetration with my little Hobart 135

what are the rear axle you are useing to get the rear axle with a driver side offset?

I'm reversing the tubes in a second identical axle.

start a build thread, that is cool as hell.
No one will see it here with this title. I dig it, different

I'm reversing the tubes in a second identical axle.

good idea . I think i will be looking into that that way i can use factory shafts :)

I gotta drag this one back up just to ask those who have done it if the t-case still runs cool or if it overheats like the np200 is prone to. I can't see any reason it would, but I figure its better to ask those who have actually done the mod.

I have two late 60's military Dodge WM300's contact maintanance trucks that has the same type of setup with two rear outputs, one drives a big welder and the other has a disconnect for the rear driveshaft. I dont know if it is a NP205 or not, i just thought it was pretty awesome.

desertwheeler that case your talking about sounds alot like the good ol rockwell 223 it's a great case just really heavy
you can find them in alot of hd 4x4 chevy trucks 70 and older

I dont know it looks like the same case that is my 47 too. And the rear disconnect is external. talk about alot of levers this thing has 2 for the tcase 1 for pto another for the rear driveshaft.

NP200 overheating is always a popular conversation topic in the M715zone. Nobody really knows with any certainty why some cases never overheat, but one thing needs to be kept in mind - With 5.88 gears, your transfer case is going to be spinning VERY fast! With taller gearing, this may not be a problem at all.

Reviving this post as I am hoping someone now has pics they can post up. Pos an update?. Can any NP205 be used to do this, are all NP205s essentially the same?. Can I get a NP205 to bolt directly to a Chevy NV4500 or do I need the AA adapter ring? Would a NP205 from a 88-91 dodge 5 speed getrag be A stronger choice, I know its only 29 sline but it is 1.5". This will then bolt directly to a dodge nv4500 without adapters I think.

I have an extra divorced t-case with two rear out-puts made for a 6x6. it only has a 1.94:1 low range though 1:1 hi
it is from a military chevy from the 40s no idea what model it and no one seems to know. asked all over the CCKW forums and WWII gmc-chevy forums.
it just seems to be known as the chevy t-case.

I am building my truck with the other one. Let me know if you are interested.

So is it the same center line drop as the np200? How much distance is there between the outputs and the centerline? A pic would be nice. Anybody gotten it to work with LoMax?

I would love some pictures of this. Could it be built to only have the one offset rear output.

Giving this a quick bump wondering about the strength of these various options. Going 6x6 won't work well with a doubler but having a single t-case with a Klune-V would....just wondering if it could handle the power from, say, a 6bt cummins or 7.3 powerstroke through that underdrive.

Another semi-related issue: for cost-effectiveness and cool factor, using a HP steering axle for the rear-most axle would be pretty pimp...but would the intermediate axle being a non-steering unit have issues with the rear steer? I can imagine the scrubbing of the rear axle trying to push the intermediate side to side. it would require that intermediate to have its own steering and that jumps the cost of a 6x6 build immensely, or I'd have to go with an offset non-steering rear axle and have the turn radius of an aircraft carrier.

Sorry the pics aren't the best but here are some pics of a dual rear output on a 205 made from 205 parts. This unit has been in service in my bronco for 2 years behind a big block Ford and turnin a 2.5 ton case powerin 66" tires. Plus I have built several others too that get abused regularly too. As you could see it was time for a new rear output seal too. Lol

Yes this works too.

Could you go into more detail on what was done to the 205 parts to make them work properly, I would love an offset rear to help with my drive line angle, but I did not want to use the np200 part since the out puts are smaller 10 spline units,

I'll try to dig up some of my pics. The case in the pics is low range 4x4 only. But I made it that way for simple reliability and I don't use the front output but there is no reason it couldn't be used. I'll have to check my notes to see what configurations can be done. You will need a divorce 205 input shaft to do this though.

Those who put offset NP200 guts into the offset side of a NP205, are you getting high AND low on the front output? I did precisely that and that output is always on low. The NP200 only has a large gear on that side, whereas the NP205 has a large and a small one.
Any thoughts?

To save pulling the loose 205 out of the attic and taking it apart, would it be possible to take a divorced mounted 205 and take the front output and stick it in the back and put the bearing retainer on the front?

Is there a better way of having a divorced case with an inline and offset rear output? Don't need any gear reduction and I don't need a front output I need an offset rear facing output that can be engaged when the inline output is disengaged.
