How to make an early GM nv4500 fit behind a Cummins. Part 2 OBS Chevy 24v Cummins swap

[@johnathanm82]

This has to be by far the most informative video I've seen thus far, regarding this, I'm in the same exact situation now. I'm going to send the transmission shop this video and seen if the can machine it down and make it work. Thanks

Very Helpful. I have a 1994 K3500 with 5 speed manual and it's a gutless thing. I want to put in a 12v cumins. Looks like this is what I need to do. I had no Idea I could just put on a Dodge bell housing and not buy the $800 or $900 adapter plate.

This video is awesome. Thanks!

Great information

[@andymcdowell7917]

What transfer case did you use

[@1badpiter458]

So from what I understand is that if I have a 96 up gm nv4500 I can just put the dodge input shaft and bell housing on the gm trans and it will just bolt right up? If so that would be so much easier than buying a $1k adapter lol.

That must have been early morning just couldn’t sleep lol

[@fullforce581]

So your main gears are suited for the 5.61 countershaft right. I've got the 93 and a guy just told me this morning 2nd and 3rd need to be swapped as well as the counter shaft

[@honeyridgehomestead3197]

What size is the input shaft? 1"-1/4 or 1"-3/8? I'm doing an 1988 OBS, I've got a 99' chevy NV4500 going on a 12v cummins.

Just some info about NV4500s - Dodge Cummins NV4500 Input shaft 1-1/4 10 spline and Main Shaft is 29 spline. GM main shaft is 32 spline I mated up a Cummins to a Dodge HD NV4500 with a passenger drop GM NP205 using Chevy 32 Spline Main shaft, 6 Hole GM cast iron extension housing and an Advance Apapters spacer. Gas Engine Dodge NV4500’s will not work with a Cummins, unless it’s out of a V10 truck.

Do u still have to change the input shaft in say a 1998 gm nv4500?

[@Victorsvolkswagens]

Most likely

[@omarflores4018]

What Shaft did you use im having trouble mines its a 94 nv4500 with 20 teeth and the ones i have searched for that fits the cummins its a 22 tooth do i have to change the bottom gear if i wanted to install it>?

[@BayWop]

Omar have you found a solution? Im in the same boat.

[@andymcdowell7917]

Would a 1994 Chevy NV4500 have the same gear ratio as the dodge input shaft

[@valentinedurasenko7066]

Did you ever try it? I’m on the same boat I believe my nv4500 is a 9;

[@valentinedurasenko7066]

94

[@BayWop]

Im also in the same boat. Have you guys find which input to use? I have a 94 also.

What clutch and flywheel do you run?

[@trucksofthemidwest6454]

Dodge clutch and flywheel. From a 99 3500
