Why Was the Cummins 555 Not Popular?

Hi,

Why was the Cummins V-555 line not so popular?

My theories are that these engines, which include the VTF-555, were an outgrowth of the V-470 (VINE) and the V-504 diesel engines, all of which are undersquare (with a 4-5/8" bore, the V-470 having a 3-1/2" stroke, the V-504 a 3-3/4" stroke and the V-555 a 4-1/8" stroke).

Here is a video of a VTF-555 in action as a retrofit engine in a 1952 American LaFrance fire engine:

Ouais ils sont à la gamme de 3200-3400 TR-MIN non sûre, mais ont entendu dire que quelqu'un m'a dit que le 555 moteur a vraiment utilisé acier pistion {que la partie je ne suis pas sûr si c'est des renseignements corrects}

Yeah they are at 3200-3400 RPM range not sure but heard someone told me that the 555 engine did use steel pistion { that part I am not sure if that is correct info }

Merci,Marc

Someone told me the 555 gave excellent service in marine use; I'm thinking they were run near WOT and no stop & go which might have helped ?
