i'm picking up a 241 from behind a cummins that supposedly had a NV4500. first off, did a pass side drop 241 come behind a NV4500 (thought they had the getrag)? second will it be the same spline count as my 435? thanks for the help.:D

93 was the last year for the passenger side drop Tcases in the dodges.. The only Tcase offered for the Diesel engine was a 205 and the manual tranny was the Getreg 360.. 94 was the first year that the 4500/241 were offered behind the Cummins.. The input spline was still the 23 spline count which allowed the 205 to bolt up to the 4500 if it was swapped into a 93 or earlier truck to replace the Getrag360..
I have heard rumors that the 241 was available in the Gasoline trucks starting in 88 with a passengeR side drop but I personally have not seen any that were equipped with that the 241..
I can Scan the owners manual and/or the sales brochure from my 93 if you would like to see what it shows..

its from behind a '93 360 engine. thanks again for the info :D

additional question:

do you think a 241 would hold up running 44's in my powerwagon with a 360/435 in front of it?:D

I dont see a problem with that combination.. I was running a 208 behind cummins with 36X12.50's with no problems after the original 205 grenaded..

hey Fullsize, if you run across an X-TRA t-case for the diesel with the 29 spline input just let me know, i'm doing a conversion and need the internals...i'm trying to mate a getrag to a passenger drop 205 or 241
thanks

That would be 23 spline not 29

I'd have my scout/cummins project completed by now if my getrag tranny had a 23 spline output, there are lots of adapters out there for nv4500 23 spline to d300's
the married style getrag shares the 6 bolt pattern as t350/t400 and a bunch of others..the 29s output shaft is a tad larger than the 23s ..i'm trying to get confimation on the spline count behind the 94 and later diesels with the 241's and 241hd's???
any of you have one you can take a look at? i may have to take a trip to the dealer to get that answer...thanks in advance
ray

The dodge diesels have 2 241's.

241dld, light duty no pto, smaller input shaft
241dhd, bigger input, wider chain, pto covers.

I did a 618 to 4500 conversion in my 96 and discovered all this after I got rolling.

All the later model 93 up dodges are l/h drop.

The 241dhd is in the "snowplow" prep optioned trucks. The output shafts are bigger as well.

No I dont remember the spline count but, could count the dld I'm shipping out today.

Joe
what did you come up with and thaks in advance

I have a question of my own???

Will the 241 mate upto or replace the 231 in the 1500's? I want to get rid of my 231 and upgrade. I don't want to use a 205 because of all the extra work it will take to get it to work.

I'd like to bring back this thread to see the answers to the above posed questions. Have one of my own, too. Will the 23 spline Dodge 241 bolt in place of the 23 spline Jeep 231? Same spline count, same bolt pattern, probably different clocking but I can work with that. Main question is shaft stickout. I have a Jeep AW4 automatic.
Thanks,
Travis

i can answer that in kind of a bass ackwards way, i swapped a 4500 for my stock 3500, and was able to keep the stock 231 t-case. so yes, the 241 should interchange with the 231. i was going to swap the 241 at the same time as the trans,but funds ran out. from the research i did, a 241 would be a direct bolt in the front d-shaft output is just a bit longer, and of course different joints so some driveshaft work may be needed. and i have personally seen a 241 in a early 90's ramcharger, so rumor is true hy_desert. 1990JeepXJ... keep in mind our dodge 231's are a bit different, we have an HD version that has a wider chain and larger bearings. i assume input shaft and pattern are probably the same though...

I'll back up the spline count on late model Dodge Cummins 241's.
I got a 2002 241HD and it has the 1-1/2" 29 spline input and the larger output shaft( can't remember the size & spline count ).

If this helps, I talked to an engineer at New Venture a while back and found out that a lot of the NVG T/C's input gears will interchange. Meaning you could get a 241HD w/ a 29 spline and change out the input gear w/ a 23 spline if that is what you need.

I found this out when we where looking to change a Ford NVG 271 to the larger 29 spline.

Changing out the female input gear might give you many more options...... HTH , Tom

O.K. Here's where I'm at now. Was gonna go with a Ford NP205 (31 spline) and put a Klune in front of that with a 23 spline input and 31 spline output. Running low on funds so started looking at the 23 spline Dodge units.
Now with the input gear swap option it seems like I can use any NVG unit with the 2.72 planetaries. So I was thinking of two things.
1) Grab a Ford NVG 271/273 and swap in the 23 spline input gear out of a Dodge NVG 241dLD (94 and later, right?).
2) Rumor yet confirmed is that Dodge actually started using the NVG 271/273 case in 2002 and later Rams. True? Pretty good odds of it having a 23 spline option, right? I believe all automatics had 23 spline and manuals had 29 splines. Thought I might hit some yards and try to confirm this with the 241dHD. The 241dHD above uses a manual tranny, so I still have hopes.
Lastly. Who knows if the 241, 261/263, or 271/273 ever came with fixed yoke rear outputs.
Thanks,
Travis

Dodge started using the 271/273 in the 2003 HD models and is a slip yoke. Ford S-D's have used the 271/273 since 1999 and has a fixed yoke.All the 261/263's that I have seen are slip yoke.
It seems logical that the 2.72 planetary set up would allow the interchange of the inputs- don't know for sure, but the 241HD and the 271 did interchange.

I think you are right about the automatic Dodge's still having a 23 spline in the 271's , there is a new auto coming out to handle the H.O. motor and it might have the larger output shaft so becareful.

Tom

the pre 94 241's were fixed output as well. are you trying to keep a driver side drop 1990Jeep? if so, you can forget cases from pre 94 dodges. but, you do have another interesting option in the form of a dana 300. a company right down the road from me, down east off road, makes a flip kit for it so you can use it as a driver drop. that's what will be slipping into my truck eventually. basically, with 94-01 rams here's what it boils down to... 1500's got a 231hd. the 2500/3500's got a 241ld or hd depening on the motor. only the 5.9 gas engines got the ld, the v10/cummins got the hd. that should be all you need to tell the difference on your junk yard hunts. try out www.car-part.com too, they have some decent deals on things.

On the 94 to 02 Dodge trucks some 2500 diesel/ V-10 trucks came with the 241 LD . It was a "snow plow " option or "heavy duty " ( PTO ) option on the 2500's and standard on the 3500's.
The 241 HD also went through some changes around model year 2000 , so not all are equal.
I am not trying to be picky but I thought it might help to know that while your in the bone yards.

Tom So I thought all Fords used 31 spline input shafts. True? So is the 29 spline shaft still larger? How does the 23 spline shaft compare to either of these in size and strength?
Thanks,
Travis

To the best of my knowledge most all the Ford case's do use the 31 spline input gears. For years the Ford 31 spline , Dodge 23 spline , and GM's 32 spline ( GM's being the largest )were all very similar in size and strength. The 29 spline is the largest spline input shaft out there that I have found. GM has started using the 29 spline in some of there applications too ( EX: ZF 6-speed ) .

All in all the 1-1/2" 29 spline is the top dog, but there ain't nothing wrong with the other sizes- there all of good size and strength, the 29 spline was just needed with such high factory torque #'s and such high GVWR's.

HTH , Tom
