Divorced t-case question

[Russell]

Hey guys!

I picked up a divorced transfer case today, but I need some help identifying it. The seller claims it is a 205, but it seems rather small to be... It has an aluminum housing, and I am able to pick it up myself. It has 29 splines behind the u-joint knuckles. Wouldn't a 205 be rather heavy? He had it installed in his S-15 350 powered Jimmy, and bought it off someone else prior to that. It has a u-joint knuckle input and front output, with a slip rear output. I am on the road right now (wireless internet, father is driving, lol) so I cannot get you guys pictures till later on tonight. I bought it becuase it was a fairly long drive down, and if it isn't a 205, or something tough enough for my K25, I will ship it back to him collect while demanding a refund.

Anyone have any ideas?

I can't quite guess what it would be (Ford Borg Warner?), but anything aluminum or 29 spline at the output is NOT a NP205.

 

[Russell]

I does have a passenger side drop, so it has gotta be either Chevy, Dodge or IH...

Divorced NP205's did not have slip yokes either...sounds like you've been had.

Being able to pick up a 205 is a relative term. I can pick up and carry one no problem.

 

[Russell]

Hmmm... I guess we will just have to identify it, and figure out if it is going to be tough enough to stand up to a fairly stout 355. If not, I know where the seller lives, and I can get my refund either way. Its a good chance he may have just been ignorant to what it actually was.

Ok, now that I am at home, I see it is an NP241. I guess its going back to the PO...

 

[NorthWestFab]

Bearing in mind those NP241's can take 5500 ft-lbs of input torque...you might want to keep it? they have better low range, the only think to be mindful of is making sure nothing can contact the case itself, as they can crack easily from a rock impact.

I'd run it.

This truck won't be offroaded often... Its being built to pull, not play.

How will it hold up with about 12 000 lbs behind it?

 

[atho]

I don't believe any manufacturer ever used a divorced NP241.

 

[Russell]

241 was a typo -- I meant 231

Will an NP 231 bolt to an NV4500?

 

[u2slow]

The GM 231 is 5-bolt. Nv4500 (and just about everything else) is 6-bolt.

All it would fit is a TH700 (with the S10 adapter) or a Getrag/NV3500 (S10 version).
