5 Ton M934 KTA19 600HP Cummins swap

[RPMRPM]

Hey guys based on all the comments on my previous post I picked up a M934 for my camper conversion. I have a customer I’ve build a few sled pulling motors for who asked if I’d be willing to take a KTA19 600 horse engine with engine brakes off him to knock a few grand off his bill since he didn’t need it and though I might want it for my truck, and I’m thinking if first that engine will fit under the hood of a 5 ton and second that Allison will hold up or if I need to put a RTOO in it I’ve also got a #10 and a #15(i think) fuel pressure button I may put in it with a bigger turbo possibly not sure I’d appreciate any input guys

You won't keep an axle input bearing, torque rod or u joint in it.. or a transfer case unless you go with a 55000 and even then your life span is limited.
Plus I don't think it'll fit and be able to have a radiator big enough to keep it cool. Actually I know it doesn't have the room.

I remember as a kid the first WHITE FREIGHTLINER POWERLINER I ever saw was in a truckstop with the huge new wide grilled cabover made to accommodate the KT 600 /3408 CAT/ OR V12 DETROIT in 73 or 74 then Peterbilt did it with their cabovers in 75 so if they can do it u can do it but its not gona b easy !

if I found a M920 would it fit in there and would the driveline hold up if the driveling wouldn’t what kinda modifications would be required I just think that engine would be a ton of fun so I wanna drop it in something

Yeah the engine was actually a marine engine he wanted me to put in an old 74 dodge big horn for a pulling truck but he decided to sell the big horn and pick up a different project.

Piece of cake… winch frame extensions, graft a couple hoods together, new transmission and transfer-case, plus light foot and GVW!

Just go with an Oshkosh K2358. It's an air force Mx missile hauler. KTA600. 6 speed automatic. 6x6. With lockers. Sleeper included too. They can be found for around 12 to 15k.

The 920 you will need more hood space than it has allowed. Plus a transmission plus a transfer case and hope you don't snap a ring gear in the SSHDs

@South check with him. I think he knows of a Oshkosh near him.

Worst case he has a complete 920 that needs an engine for sale.

You know if it would be possible to stretch the hood on the M920 so I could fit the KTA Im getting from my client in it and take the drive line in the K2358 since I really hate the look of cab overs personally and put it behind the KTA in the 920 if I just bought both of em?

The hoods on the 915 series trucks are a pain in the rear. You would have to stretch the hood and fenders since they are different components. I can measure it since I've got a few 916 920s laying around and a KTA600. its probably possible with firewall revamping probably. Or scoot the cab back and connect it to the front end

I have one of the Oashkosh K-2358 with about 25k miles on it. It's in top shape and doesnt look older than 10 years even though it was built in 1986.

The series 915 looks easy, 939 not so much.
