Divorced D18's?

[joe]

For a future project/lash up I think I may need to go with a divorced x-case. Weren't some divorced D18's used in maybe some non-Jeeps apps...or am I just having a blonde moment here?
Any options for a divorced x-case(of any flavor) besides the 205? I don't need the ultra bullet proofness of the 205. Something of D18/20 strength is adequate. Oh yeah...needs to be righthand drop too. Thanks.

There are several divorced cases out there, but as far as I know they are all the size and weight of the 205. Why not go with a 205, there are a lot of them out there and it is what you're looking for?
:cool:

friend of mine just bought a novak adapter used from someone on the JU page to make a d18 or 20 ito a divorced xfer. you might check on pricing on a new one from novak or AA or keep your eyebells peeled on jeeps unlimited,pirate4x4 for sale forums,and on Ebay.

doesnt look like it would be too hard to make. seems you could simply cut the rear off of a t90 or t150,and modify the outputshaft to have a yoke on 1 end. using part of the tranny like that youd have the mounting surface.and a bearing and seal to support the shaft,as well as the splines for the input gear.

like 64 said,i cant really think of ay other xfer cases that came divorce mounted that wernt as big ad heavy as the 205. i also dont think that the d20 or 18 ever came in a divorce application from the factory...

Thanks guys, I'll look into the adapter thing since I've already got a couple of D20's.

Land Rover used to use a divorced case, it was pretty beefy from what I've heard.

Other choice is the option, that any case can be made into a divorced case... All you really need to do, is to use the tailhousing from the transfer case in front of the tranny (remember there's a seal between the two) machine (cut/grind) it down to basically be just a cover plate. Then have the output shaft modified to accept a yoke (might be as simple as cutting it and drilling/tapping a hole)

for the sake of novices like myself and all the multitudes that would never ask in fear of showing their shortcomings :eek:

and for all future FSJ'ers
Would you guys please DEFINE a "divorced case". :confused:
Thanks

Hummm...I'm liking the idea of reworking the aft end of a donor trans. I can come up with a sacrificial T90 pretty easy.
Plan B might be trying this with a T-5/D300 twin stick combo I already have...sacrificing the T-5 for a good cause certainly won't cause any saddness.

BOM, a divorced case is one that's connected to the trans via a short driveshaft rather than being bolted directly to it.

What about the rockwell cases that came in some early scouts?

The D20 came in a divorced unit (D24) for fords but that is a drivers side drop. There is a divorced case in Datsun/Nissan pick ups that looks to be similar to the D20 in size and strength but I do not know for sure if it is.

[Shake N Bake]

That Nissan case is pretty beefy, I love old nissan/datsun kingcabs. Almost unbreakable (I know there is a KingCab guy on 40s, running a 4.3/700r4 who swears the thing is unbreakable)

The conversion of any case to a divorced unit is a undertaking... Don't get me wrong, its easy to explain, but the machining can a pain. Modifying the input or output shaft (depending on how things are setup) can be expensive, and the weak link (you'll be cutting the shaft, possibly adding splines, drilling/tapping the center. could require some heat treatment to ensure strength. Might be better to just have a new input shaft machined) I've seen it done 2-3 times now, haven't seen a problem with them yet, but its still something to keep in mind.

Andy what rough spread of years should I be looking at for a Datsun x-case donor?

[Shake N Bake]

Think the first kingcabs came out in 79 or so, not sure when they finally changed the case design, but it think it was 87 when the newer body style came out that they went to a married unit... Just look for the old style 4x4 Nissans, the ones with the boxy body lines...

Now if you want some real fun, go looking for a Nissan kingcab diesel (decent engine, now a powerhouse tho) Get it and its tranny, then a tcase out of another truck, put em together for a real fun rockcrawler drivetrain. Light too! I've never seen one that came that way from the factory, but you might stumble across one.

ooooh,oooh,ooooooohh! i completely forgot. what about a samuri t case? they are divorced,very small,light,and compact,have a pass side drop,and you can get lower gears and cool stuff for one thru calmini :cool:

they look to be about the size of a d18 or 20,maybe alittle smaller. have seen ones internals,but its been a long time,so cant really remember the size of gears and whatnot.

while your scroungin lookin for a nissan t case,you might have a look at one and see if you think it may fit your strength requirements. samuris are fairly abudant.

Joe, don't forget that the M-715 came with a divorced D-21, IIRC. Can't be too different from a D-20, so it should be doable.

The M715 x-case(NP200) is a Big Mutha and a bit overkill for my needs but thanks anyway. ;)
FWIW the D21 is a single speed version of the D20 used in the early Wags with the 230/AT combo.
