Engine/Transmission (1994 - 1998) 12v injector and piston diffrence

[NFoster]

Hello all I have a question to throw at everyone. I have a 850 case dozer with a 5. 9ctd rated at 96hp. It is wore very bad and I was wanting to know if a 5. 9ctd from a 95 dodge pickup work if I change the pumps out and leave everything else the same. I figured there might be a slight diffrence in power do the slightly lareger injectors in the truck motor but if there are no changes made to the pump there should be that much of a diffrence. Just wanted to get some thoughts from everoneif they thought this would work without any problems.



Thanks Nathan

in short will a pickup long block work in my dozer help?????????

I don't know the answer, but maybe if you took the engine numbers from both and contacted Cummins, they could answer you.

There are lots of internal differences between auto and ind engines. First there is the emissions stuff, like timing etc. Then there is the rpm difference. The truck engine goes through a broad band of rpm whereas an industrial unit will quite often go from an idle to a set rpm and stay there, as an example. The fuel pump governor is totally different as a result. Because of horsepower differences ( I think your Case will be more than 96hp as a 4BT will put out more than that ) the pistons, injectors, turbo and cam can all be different. Because this engine came from a Case machine your local Cummins shop will not be able to break down the serial number. Although the "B" ( and "C" ) series engine were built as a joint venture between Case and Cummins, think of it as them coming off the assembly line and the Case ones going left and the Cummins ones going right. Case wants you to go to them for the parts and service. So in short although it will "fit" IMHO it won't run properly. Shadrach

I know the timing pumps are differnt that is the whole point. If I take the truck engne and just use the block with it's internals the truck head and injectors and then put the dozed pump on it will it be about the same as what I already have I one there may be a slight diffrence in the injectors resulting in. A diffrence hopebto get a little more power. But all in all will it work?

Is it a straight 850? or a B or C? The engine should be the same anyways. If you swap the pumps, it should make very little difference. Check the engine tags on both and see what year it was built. If it's close, it won't be a problem. I bet the pistons are even the same.

Shoot, couple guys around here swapped bread truck engines into their 450C's. They even left the turbos and pumps on. Works great!



PS, I work for the local Case CE dealer.

850b and [most] c's will be the case diesel engine, not the case/cummins engine. my opinion, take the long block verson of your dodge engine, swap the fuel system off the dozer , setting the timeing to the dozer spec would be wise also. if the dozer engine isnt in too bad a way, would it be simpler to just do a rebuild on it? rebuild kit avg about 750. 00 ish or so.

I swapped a bus motor into my truck had to swap the truck parts onto the motor but all the holes were there. had to tap the holes for the linkage as they weren't tapped on the block but were there . I'll be you could use any B5. 9 block . If I got one with a p7100 pump on it that's what I would use . I'm assuming yours is turbocharged to use the p-pump

It will work just as it is do your swap and watch it run the pump on your 850 is probably a rotory and the 95 is P7100 your linkage will be diff. Have fun
