Is there such a thing as a 24V industrial, like a Gen set or water pump, or are they 12V? If there is 24V what do they use for a lift pump? Do they have a VP-44? And/or what do bigger medium duty trucks use?
Thanks

 

6cylinders I wish someone would answer. I would like to know also. That's an interesting question you posed.

 

As I recall, every industrial Cummins I've seen is a 12 valve with a mechanical pump. (Less stuff to install, and less stuff to go wrong at the worst possible second)

 

The only industrial 5.9 cummins I have been around was run with natural gas. It ran an irrigation pump.

 

they have 24 valve industrial engines, I bought one and installed it. Worked well when changed over to vehicle use, but it was a 53 block and cracked right away. This came from a gen set. Cam timing has better torque, near what the commercial engine has.

Lift pump was the same, exhaust completely different, injectors were tiny, I used my vp44, don't know about the original but it was a vp44.

Best engine to use for pulling weight, commercial unit from a bigger truck, school bus, etc. They are limited by the vp44 to 2500 rpm so have a low hp rating but high torque. I have an RV275 in the Dodge, not just the injectors, the whole engine. Real strong. Rated at 275 with 2500 rpm is quite high in comparison to a dodge engine based on 3300 rpm.

 

Same as Haulin_in_Dixie ,, I too bought one, ISB 185, Out of a 35 pass airport bus That burned,Engine was 55 block (heehaww) 8525 Miles on it,,,, Same lift pump,, Different VP-44 For Mid range app, redline @ 2500 Rpm cause of VP. And small injectors,, I changed injectors and put my Vp-44 on it, Runs GREAT I now have about 30000 miles on it AND I'm 53 FREE!!!!!!

 

I have one i am parting out. It is in a Bearing MD 26. That is a 26000 gvw straight truck. Rated at 215 HP has the same HX35w but has a band type downpipe clamp. The guys at cummins up here said the vps on them were the same as the pickups (wanted a spare) and that an ECM flash would put them in our pickups rpm range.

 

Here is a picture of the fuel system on a generator set placed into service October of 2000:

 

we had a 24V cummins in our *gasp* ford F750 bucket truck. Whether or not it was running the VP-44 I could not tell you but from what others have said I gather it was. I do remember it having a really low rev limiter but I couldn't tell you what rpm, just that it would fall flat on it's face if you didn't shift.

 

That is not a 24 valve engine.,,,

 

As printed that is wrong information. The ECM will not raise the rpm of the VP pump. There is a module on the VP that can be flashed by the proper equipment, but for all practical purposes that is above our abilities to achieve.
