Over the summer my Dad and I swapped a Cummins into a V10 Ram. I know its been done but it was hard to find information on, so i figured id write this up with the hope of helping someone...

Started with a 1996 Ram 2500 4x4 V10 with the 47RE transmission. The truck had around 180,000 miles on it and I had owned it for 2 years with the V10. No problems with the V10, good engine, terrible gas milage while towing (got 6.5 towing a trailer to Tennessee).

So with the help of a friend,
https://www.facebook.com/Whitetrashfabrication?fref=ts, guy puts Cummins motors in everything. I found a 1989 Cummins motor with 150,000 on it and got it with a 3 speed trans for 900 bucks. This was a mistake... but more on that later.



So I started taking the V10 out. But left the tranny, wire harness, gas tank computer, ect.

Cont.

So the story on the motor. Was in a truck that ran into a tree. The guy pulled it and covered it and it sat for years. Well this as well as the tree led to some problems. First the motor didnt have the fan pulley, bracket, it got bent in the accident. So i had to find one of those (ebay), But the worst part was the injection pump ended up being shot :doh: .... So i had to replace that. Fun stuff. But with a new injection pump it started up and ran great. :party018:



Back to the swap:
So with new motor mounts on it i went ahead and test fitted the motor... And it didnt fit... The 89 motor was set up with a 3 speed originally and i was bolting it to a 47re. The 3 speed doesnt have overdrive so the torque converter is skinnier than the new overdrive torque converter. :banghead:

(NOTE: i did change the torque converter on the transmission to a diesel one, simple, just take the old one off and slide on your new Diesel 47re Torque converter.)

SO this was a major problem and after a little searching on the internet i figured out that i needed a new transmission adapter plate... So looked at prices... :shock: 700 bucks!!!!!!!! This was getting expensive.

But i had an idea, What about Destroked, they take those plates off and use the ford adapter plates, called them, boom got 3 for cheap. So if you need one call Destroked.

So i swaped the plate and it bolted right up NBD. :thumbsup:

So the motor is in. :party018:

Now i left the original V10 wiring harness and Computer. With the motor in and no sensors hooked up and the new injection pump....:doh:, the truck fired right up and i pulled the TV cable tight, make sure you do that, i could drive the truck with "3 on the tree" :party018:

Now to make it shift by itself...

The V10 computer looks for 2 things, as far as i can tell to make the the tac/alt work. The Cam position sensor and the Crank position sensor.

EDIT!!!
I dont know what i was thinking. I wrote the first step wrong. DO THIS!!!
The relay is still used, but instead of sending 12v to the cam sensor(this is wrong), the relay is energized for a spit second the starter is on, this takes signal from the crank pos sensor and sends that into cam sensor signal wire.


Next the Computer looks to the Crank Pos sensor to count RPM's and this also keeps the alt on. So i got a Cummins crank position sensor and bolted it to the front of the gear cover to count the grooves on the harmonic balancer.

Now before you look at this and tell me its not gunna work or what have you... It works fine, been like this for months, over 8,000 miles sense.

But the problem was the V10 crank position sensor looks for 10 grooves and the harmonic balancer i had only had 2 grooves. Now i could have takin it to a machine shop and have them cut grooves in it but wheres the fun in that?

So i did this....





And with the .050 gap, boom the Tac works the alt charges but still no OD.... Hmmmm :confused013:



EDIT!!!
I dont know what i was thinking. I wrote the first step wrong. So do this

So got the tac working, battery charging, And i missed spoke on that, it shifts 1-3 auto now that the tac is working. Had to adjust the TV cable and i just clamped it of so it had good line pressure till about half throttle then the cable gets pulled from there to WOT for passing gear.


But i still dont have 4th/OD. So with a little more research i figured out you can remove the relay for OD and just use a switch, its out there on forums, just search for it. If you can find it ill show you...

So with the switch hooked up the truck goes into 4th and OD.

I guess thats pretty much it. I hooked the AC compressor to the original plug, I used the V10 thermostat for temp. I did change the gauge cluster out to a Diesel one, everything works as it should, except the Tac, its off by like 300 RPM but if you hook a scanner to the OBD2 plug it reads less than whats displayed on the RPM gauge :confused013:

List of parts youd need

95-98 12V motor mounts
Adapter plate if you buy a older motor
New Torque Converter (I used the V10 valve body seems to work fine)
Crank Pos sensor
Relays
A new starter if you change backplates


I think thats it possibly more, if i remember anything else ill post it. If you have any questions feel free to ask, The swap was awesome and the truck runs so much better with the Cummins!:woohoo:

quick thing, Last week the relay went bad i had set up for the cam pos sensor, when i fixed it i also put a new crank sensor on. When i did this the truck now shift 1-4/OD by itself and then you flip the switch and it goes into full lock-up, and wont unlock until you flip the switch (like a standard tranny with a clutch)... No idea what changed but if i figure it out ill post

Added an Intercooler this weeked to the truck

Added an intercooler

95 Cummins intercooler

All the mounting holes are there but i had to get a cummins radiator for it to fit:doh:, the lower port on the V10 radiator is to low and interferes with the intercooler. But with a Cummins intercooler and a PUSHER intake i got it all on.

Had to make new mounts for the AC condenser and Trans cooler but it all fit great.:party018:

can someone help me ? i have a 99 ram 2500 4x4 extended cab short box v10 4speed automatic truck with a blown engin "rod"@59,000 miles

i have a 2002 5.9 ism 235 engine only no trans from a wrecked truck that had a five speed Manuel . i thought everything was going to be there to do the swap without customization's "plug n play" but the wireing is completely dissimilar ! am wondering what more is needed to make the swap "correct"

as i am not trying to rig it up . its a nice low mile truck with no rust and solid 5.9 ism235?

the wire harness on the 5.9 is complete just nowhere for it to plug into ! is there any way i can use the v10 radiator and transmission and what all will need to be changed as far as the wiring /fuel system

anyone willing to help a long time dodge fan out is encourged to email me @ [email protected]

Hey so you did awesome with the thread. Here's my question. I put an 89 12 valve in my 98 ram 2500 that was previously a v10 fuel hog. Everything works but I have no clue how to do the tachometer. I'm aware I need a tach sensor but no clue how to hook it up and do the cam sensor/ crank sensor stuff and the grooving of the harmonic balancer.

So I have a 94 ram 3500 4x4 with the v10 in it I have had it for years love the truck I bought a 98 with 24v in it to swap into my truck well I couldn’t get the ecm for it so had to scrap that plan I traded that truck for a complete 89 12v engine last year i have sense been gathering parts for the swap first question I have that I am not sure on is with the mounts on the frame work or do I have to move them I have a bran new tourqe converter and flex plate and second gen adapter plate I am going to put a 35 gallon bulk tank in the bed and not use the stock tank I was thinking on the charging issues I’ll put an older stand alone voltage reg in that way I don’t have to deal with the cutting more notches in the balancer is there any other things that I may run into I need to know
