Problem swaping input shaft np249

Hi

In from norway, so excuse my english writing

I have a -95.mod 5,2 v8 ZJ. And the transfercase broke down. So i by a used transfercase, from a -93.mod 4l. So i had to change the input shaft.
But the case i by have early gear cut and mine late gear cut.

So my question is what du i have to change so i can use the new case?
Do i have to change the front case or can i just change some parts??

Thank you for answers

Jeg håper dette er det samme språket, haha. Hva er min forståelse er at du blir nødt til å bytte fronten tilfelle av 242 (L6) i 249 (V8). Er jeg riktig å anta at du har en 242 eller en 231 og en 249 ikke sant? Kort sagt å svare på spørsmålet ditt, må du endre innvendige av 249 ut og bruke de 242 innvendige med fronten tilfelle av det.

Jeg kunne muligens ha den bakover, la meg dobbeltsjekke?

I hope this is the same language, haha. What is my understanding is you will have to swap the front case of the 242(L6) into the 249(V8). Am I correct to assume that you have a 242 or a 231 and a 249 right? In short to answer your question, you will have to change the internals of the 249 out and use the 242 internals with the front case of it. I could possibly have it backwards, let me double check?

Both cases are 249. But the one is from a GC whit the L6, and mine is frome a v8. And they have differiend input shaft, and differiend gear cut

Jeg så ta tilbake det siste innlegget og ha søk etter det som ser ut som du må knekke saken og bytte gear. Litt verre enn det høres ut, men ingen rakett vitenskap involvert. Hvis du må bytte da i tillegg til skiftenøkler du trenger gode snap-ring tang (hullete og flat - spre 1 til 1,25 ").. Et andre par hender er også svært nyttig Linken nedenfor viser en langt flott write -up og bilder på toppen for å hjelpe med eventuelle visuelle problemer.

I then take back the last post and have search for what looks like you have to crack the case and swap the gear. Slightly worse than it sounds but no rocket science involved. If you have to swap then in addition to wrenches you'll need good snap-ring pliers (holed and flat - spread 1 to 1.25"). A 2nd pair of hands is also very helpful. The link below shows a by far great write-up and pictures on top to help with any visual issues.

Use the 249 front case half and input assembly that was original to your Jeep.

Correct, keep the original input gear and the original case half together. Those will have matching gear cut's..

To be clear, your using the case half closest to the transmission. With the original gear inside and the original input gear to that 249.

If you look closely at the gears, you'll see where they differ. One set will have a flat on end, where the other will have more taper. You don't want to mix these.
