5.9 swap

[Doe69936]

Could a guy swap out an industrial 5.9 24v with a pickup truck 5.9 ?
Are the blocks the same so one could use the industrial versions pump,electronics and so fourth or are they different?

the electronics are different for sure... if your school bus transmission is electronic you need the industrial comouter's J1939 link to run it correctly.. alrternatives exist but from my experience dont run the transmission near as well as the J1939 data link that the later ones have..

That part would be easy because I would be using all the electronics from the industrial

My understanding is that if you swap the accessories and sensors over it would work more or less fine. The pickup version obviously won't have the air compressor and fan setup and there may be differences related to level of tune, I haven't read my ISB manual yet.... But I think it would run pretty well if not perfectly.

Thanks for the reply sure seems like it would work not much into performance tuning anyway

oh i had it backwards.. i was thinking you were bringing in the pickup version because you wanted more power and support of the aftermarket pickup tuner crowd...

No I'm just needing a rebuild or new motor depending on what I find when I get to popping off the head so I'm spit balling ideas one of them was the feasability of checking prices at at junkyard for a dodge truck motor

I suspect that you can buy a 5.9 equipped bus at auction for not much more than the pickup motor from a junkyard. Pull the engine and scrap the rest.

I read some Cummins literature a while back that was talking about B50 numbers. It gave one number for standard duty and a significantly lower B50 number for severe duty.

School bus applications were considered severe duty.

Alot of stop and go mixed with drivers who don't have to work on em

The core long block will be the same. You'll have to swap alot of the external pieces over though because I know those are different. Best to swap the ecu as well.

Make sure you go year to year though. There were many changes over the years and a lot of it isn't documented.

Furthermore, industrial usage is the term they give for gen sets and prime power like pumps. You don't want to get one of those.

The term you're looking for is commercial/on highway. That's what is found in buses. Automotive would be considered dodge trucks.
